Loading and Totals
The general rules are that the panel is capable of supporting up to 200 devices per loop; this can be a
combination of Detection, Callpoints, I/O units and Sounders.
The protocol and internal memory are constructed in such a way that there are certain loading rules
which must be strictly enforced.
Maximum 200 devices per loop
Maximum 60 sounders/beacons/sounder beacons (set low) per loop.
Maximum 20 I/O units per loop which assumes each I/O uses 3 output channels;
Maximum 120 Output channels based on 2 + 3 above.
Certain devices have been constructed to circumvent these rules effectively ‘fooling’ the panel to
offset some of the totals. The maximum 200 per loop CAN NOT be changed.

Assigning devices to the relevant zones can be done either at the panel direct or by using site
installer. The contractor should always provide the zone information, as this is part of the system
design process and takes into account the fire compartment boundaries, which you may not be aware
The panel has 96 zonal led’s, if ringing patterns are required across a network then all zones must
exist on all panels within the network.
eg. Panel 1 has zones 1 –10 in use, Panel 2 zones 11 – 20 in use, Panel 3 zones 21 – 30 in use.
In this case ALL panels would have zones 1 – 30 programmed onto Loop 1.
Panel 1 would have devices in zones 1 – 10 but none in zones 11 – 30.
Panel 2 would have devices in zones 11 – 20 but none in zones 1 – 10 & 21 – 30.
Panel 3 would have devices in zones 21 – 30 but none in zones 1 – 20
Access Codes.
There are four access codes for the DF6000
User Code: This allows control of the silence, evacuate and reset functions and also
enable/disable; replace device and check auto config functions. This code can be changed to
a site-specific code.
Engineer Code: This gives access to the engineer parts of the menu, which are used, for
learning and programming the system.
High Level Codes: These 2 codes give access to menu’s which:
1. Can be used to return the system to its factory settings, and to change the logo’s on the
2. Disable ALL Outputs.
3. View all access codes and reset to default codes.
Disable/Enable Devices.
This menu allows the customer to disable and enable selected detectors, zones or I/O’s.
Detectors and zones are self-explanatory, simply touch the Enabled/Disabled box against each zone
or device.
The disable I/O menu however, allows the user to disable FRE, FPE, AUX relay, Fault output and
panel Sounders 1 & 2.
When the panel is in Auto learn individual sounders CANNOT be disabled, the only method of
disabling sounders is by using the ‘Disable all outputs’ function, or, download text into the panel,
which will then allow the sounders to be disabled by zone or individually.
If a device is already ‘in fire’ the system will not allow the user to disable it. The zone that the device
belongs in must be disabled; this function is still available if the panel is in fire.
If a complete zone is disabled, individual devices within that zone cannot be selected for re-enabling.
If the panel is part of a network then devices can be disabled across the network by using the
‘Network disable/enable function’.
Amended: Mar 2013
Replace Device.
The replace device function is used to change faulty equipment without the need to change text or
zone allocation.
The faulty component is changed and then the replace device function selected, the loop and address
of the faulty device are inputted and the panel then scans the loop for address 254, when it receives a
reply the previously inputted address information is programmed on to the new device.
This function cannot be used if a different type of device is replacing the component. ‘Add/Delete’
device function must then be used.
Check Auto Config.
This function has two purposes, the first is to check that when a database has been downloaded the
transmitted data matches the device data on the loop and then it highlights any anomalies as device
unknown or device type mismatches.
The second is to pinpoint any o/c or s/c faults on the loop. The panel achieves this by electronically
disconnecting the return legs and interrogates the devices on the loop. If there is a break the panel
will go to fault stating the first device it cannot see beyond the break. This same function also
pinpoints short circuits in the same way, creating a fault beyond the point where an isolator has
A sounder delay is set up using site installer and is must be programmed on stage 1 of ‘Device
Outputs’. The maximum time is ten minutes and it can only be programmed in whole minutes.
When programming a delay on the panel sounder circuits the zones selected in the allocate devices
box trigger the delay. Whereas on the loop powered sounders and the sounder controller unit the
zones not selected will trigger the delay and the zones selected will operate the sounders
The above has been changed in V1.81.01 Display/V1.83.3 Loop so that the devices selected in the
list will trigger the delay and the devices not selected will have no effect.
The delay trigger can be by address, zone, panel or globally.
When selecting the trigger to be by address all the addresses have to be on the same loop and the
limit is sixteen.
When selecting the trigger to be by zone then the limit is sixteen zones, which must be on the same
When triggering a delay on the panel sounders by zone the limit is reduced to 8 zones. If no zones
are selected then the delay will be global.
When a delay has been set up (on a sounder or an I/O) the sounder fault and general disable
led’s will be illuminated permanently.
Alternatively on later hardware/software versions the ‘Delay Active’ led will be illuminated.
A delay can be set up on the Sounder control unit and 3 Chan I/O in the same way as a loop powered
sounder, however, only stage 1 of output 1 will accept the delay.
The other 3 sounder circuits or 2 relay channels WILL NOT accept a delay.
Amended: Mar 2013
Double Knock.
Double knock operation is programmed on site installer and is used to prevent unnecessary
evacuation of the site. Two fires are needed from the selected list before the output condition is
satisfied and the output can operate
The operation can be done by address, zone, panel or global. Later versions have included the
opportunity to double knock WITHIN an individual zone (any zone 2 devices)
When selecting the trigger to be by address all the addresses have to be on the same loop and the
limit is sixteen.
When selecting the trigger to be by zone then the limit is sixteen zones, which must be on the same
panel. Selecting by zone means that two different zones will have to be in fire before the output
condition is satisfied.
When selecting the trigger to be global then any two fires on that panel will satisfy the output
If double knock is required to operate across the network then selecting by panel will allow any two
fires on the selected panels to satisfy the output condition.
NOTE If Double knock is set by zone – any 2 devices within the same zone will NOT satisfy
the condition.
Coincidence (Dependency type C).
Coincidence is different from double knock in that two fires from the allocate device list are required to
satisfy the output condition but one fire from outside the list will also satisfy the output condition.
This function is similar to double knock in the way that it is set up i.e. by address, by zone and has the
same restrictions on the number of trigger devices.
NOTE If Coincidence is set by zone – any 2 devices within the same zone will NOT satisfy the
Weekly Test.
This function allows the user to perform a weekly test single-handed.
Once this function has been selected the panel starts a four-minute timer, when a call point is
activated within these four minutes the panel will operate the sounders and then silence and reset the
Once this has been done the weekly test mode will be cancelled. If no call point is activated within the
four minutes the weekly test mode will be cancelled.
During this test mode the relay outputs controlling plant and equipment shutdown will not
operate, neither will the FRE nor FPE outputs
FRE: Fire Routing Equipment typically used to operate a remote centre communicator.
FPE: Fire protecting Equipment typically used to control fire doors.
Note: If ‘disable all outputs’ is selected, weekly test or walk test will still make the sounders
Sounder Level Test.
This option allows for Db readings to be taken without causing too much disruption to the site
Selection of the sounder level test mode turn the sounders on for 15 seconds enabling a reading to be
taken and then turn them off for 30 seconds allowing the engineer to move on to the next area.
Amended: Mar 2013
One Man Walk Test.
This function is similar to the weekly test feature, this allows the engineer to test the complete system
without having to continually return to the panel and reset it. Once all devices have been tested the
‘Stop’ button can then be operated.
Test Device
This is not a true test of the device. Individual devices can be identified using this menu.
When a device is put into test the fire Led will illuminate or a sounder will sound and a relay will switch
Following an Autolearn test device can be used to indicate cable routes and in what sequence the
panel has numbered the devices etc.
On v3.0 software Next/Previous has been added to enable the user to navigate this function more
easily also the relay of an I/O device will change state.
Auto Learn.
This is the process of addressing the devices on the loop. The process starts telling every device to
open its Isolator. It then numbers the first device and tells this to close its isolator, the next device is
interrogated and given the next number this continues until all devices are numbered in sequence.
On version software (v 3.0 introduced August 07), Autolearn by loop has been introduced. This allows
a second loop to be learned without having to relearn Loop 1.
If a second loop controller is installed then the option to learn loops 3 & 4 individually is displayed.
Pre-Addressed Autolearn has been added. This allows the engineer to Pre-Address the loop
devices in any sequence using a hand held programmer. (CF800) Once the system is installed, preaddressed autolearn only interrogates the devices without renumbering and saves the device list in
memory. Note This method does not support holes in the numbering system.
Maintenance Autolearn is a recent addition from Display dated 20/7/12 and loop version which has been added to support the Hybrid devices.
A hybrid is a device taking 1 address that supports up to 32 Radio Fire devices. The hybrid can be
added directly to the number sequence but its associated radio devices can ONLY be added using
the Autolearn. Clearly this is not acceptable on established systems therefore the maintenance
autolearn has been developed. When this feature is initiated:
1. It supports holes.
2. It supports the Hybrid by putting Radio devices attached to it at the end of the loop.
3. It will address a device with a 254 and place it into the next available address or at the end of
the loop whichever is available.
4. It will leave the zoning and text information alone.
5. Most importantly it will not alter the cause and effect of the existing devices.
Amended: Mar 2013
Analogue Level.
The analogue level reading is used to display the analogue value being sensed by the detector, this
value is displayed in a numeric format and also in a graphical form. This reading is displayed in real
On v3.0 software Next/Previous buttons have been added to enable the user to scroll through the
addresses more easily. The min/max values are erased on exiting the menu and resetting the panel.
Printer Settings.
When the printer is fitted then there are two options for its operation: Auto and On Request.
When changing between the two, the panel needs to have a hard reset or power down/power up to
see the change in the settings.
If the printer is replaced then a hard reset or power down should also be carried out to recognise the
Programming I/O and Sounders & Sub- Menus.
There is a number of sub – menus within this screen.
1. Panel Outputs
The only sounder programming which can be changed on the panel is the sounder tone and the
volume, if these settings are changed then the changes are applied to all the sounders on the system
whereas if the settings are done on the site installer software then it is possible to individually
configure the sounder tone and volume for each sounder.
These controls only apply to loop powered sounders.
There are three volume settings; Low, Medium, High; and four tones: Pulsing, Continuous, Two Tone,
Slow Whoop. If the sounder settings are not altered on the panel then they will default to two tone and
medium volume.
The panel sounder circuits are limited in the way they can be programmed, the three stages available
to the loop sounders are not available for the panel sounders. They should really only be used when
the system is a one out all out configuration, if anything more complex is required then loop sounders
are the best option. If conventional sounders are required they need to be controlled by a sounder
control unit.
Amended: Mar 2013
2. T1 & T2
Also contained within the above menu are T1 & T2, this feature to enables the user to acknowledge
an alarm and investigate the cause before the building is evacuated. (see Fig 3 )
T1 time delay is between 10secs and 3 min.
T2 time delay is between 1 – 10 mins.
If T1 is set to a delay this will delay the operation of ALL outputs or FRE only (selected in this menu)
until T1 time expires.
The sounder programming will then revert to the site installer program minus any programmed delays.
When T2 is set and silence alarms are operated before T1 expires, the delay set on T2 will start.
When this time expires the outputs will revert back to the site installer program plus any programmed
delays. Both must be set if either is reqd.
Both of these delays can be overridden by the operation of a Callpoint or the input of an I/O. (this is
also selectable within the T1/T2 menu)
If Day/Night mode is selected, the first fire during night mode overrides T1 such that the outputs will
revert to site installer program minus any programmed delays.
If a Non Fire Input is used to set some cause and effect then this will also override T1/T2
When the delays are running during an alarm condition, a countdown timer is displayed on the
screen to indicate time remaining before operation of the outputs.
T1/T2 can also be switched on and off/on using the input side of an I/O or Callpoint programmed to
disable devices within the Site Installer input programming. (see page 18).
Amended: Mar 2013
If T1/T2 is required on a site where these delays need to be active during certain times and turned off
at all other times, generally a member of staff would need to operate the callpoint or I/O.
However, within the T1/T2 menu is a feature called ‘Auto enable delays’. This feature enables the
user to automatically set T1/T2 at the required times as a backup if the input is missed.
A more recent amendment (July 2011) has introduced an automatic disable feature to run alongside
the auto enable feature. (see FIG 5)
The release dated July 2011 has also introduce extra features within the T1/T2 the first of which
allows the user to select which internal outputs respond to the T1/T2 time delays (see FIG 6)
Amended: Mar 2013
The second feature allows the user to select which external outputs should respond to the T1/T2 time
delays. This feature is programmed through the device outputs dialog within the Site Installer
All external output devices are defaulted to follow the T1/T2 timer and are unchecked not to follow.
Amended: Mar 2013
3. Alarm Verification Feature
When this is set any detector that enters a fire condition will show on the panel but no sounder
program will be activated, a 15 sec timer will start. At the end of the 15 sec, if the detector is still at
alarm level the sounders will activate. If during this time the detector has dropped below the alarm
level then the panel will not go to alarm.
This is particularly useful to prevent false alarms from detectors where the smoke is from other
sources other than a fire i.e. smoking in bedrooms.
On later version software the AVF length can be timed from standard or long delay (30 secs) and
when in UL 864 9 edition mode a longer time (60 secs) has also been added. (see page 27)
A further option includes the addition of AVF on specific zones.
4. Auxiliary Board
Extra boards or additional features for other markets can be installed within the DF6000. These
include Extinguisher and Fire brigade boards to enable the control of other services within buildings in
Australian Mode creates a re-configured display screen when class change is shorted. In this mode a
key-switch device is installed on the front door of the DF6000 panel which can only be operated by
the Australian fire brigade (this key-switch shorts the class change). Address or zone text for the
alarm can be viewed on the screen depending on how the screen is configured. (See page 21)
The re-configured screen gives the Fireman controls to; silence the alarms, mute buzzer and reset the
panel without having access to the pass-code.
Swedish mode is very similar except that the panel must be in Swedish language for this feature to be
5. HMO Mode
This feature has been added to accommodate BS 5839 Part 6 – Fire Alarm Installations in Dwellings.
BS 5839 part 1 does not cover private dwellings, however, a landlord is required under this to protect
all common areas within his building, and generally this would be designed as L3 coverage with a
detector and sounder in the lobby area of the flat.
Mains smoke detection would then be installed within the living accommodation to provide protection,
but preventing a false alarm in a flat evacuating the whole building.
This system is set up using the menus on the panel and the Site installer program.
Each sounder within a flat should be programmed to go continuous by the HMO zone or device
addresses in the flats up to a maximum of 16.
The adjacent zones can then be programmed to go pulsing after a delay which will be the same as
the reset timeout explained below.
There are 3 settings within the HMO menu;
1. Class Change; this is the controller of HMO mode, when class change is set to ‘global alarm’
the mode is on. In this instance, if there are any pulsing sounders adjacent to the zone in fire,
then operation of class change will change them to continuous. Setting class change back to
‘normal operation’ on the screen HMO will be turned off.
2. HMO Zones; This button allows the operator to select the zones required to be in HMO
Amended: Mar 2013
3. Reset Timeout; Detectors within the HMO zone can be set on a delay from 1 to 5 minutes.
Essentially this is an extended version of Alarm Verification (section 3 above), if smoke or
heat puts a detector in fire, the panel and detector will indicate this, but will not activate any
outputs unless specifically programmed to do so. If the smoke or heat clears within the
timeout period then the panel will reset. If smoke or heat remains until the timeout period has
elapsed, then the programmed cause and effect will commence.
Note; Only Photoelectric Detectors and Heat detectors can be used with this mode
Opto/Thermals will not operate until a change to the loop code version dated Oct 11
6. Sounder Tone
Recent product introductions include an Australian Bell Tone electronic sounder for school
applications. These operate as normal electronic sounders during an alarm situation but go to bell
tone when class change is operated.
This feature is at odds with the HMO settings above so the panel must be informed if these sounders
are installed. Once installed within this menu HMO cannot be set.
7. FRE Double Knock Override
If FRE double knock is required in the panel programming, certain devices can be chosen to
automatically override this setting if triggered.
Options within this menu include Optical, Opto/thermal, Heat detector, Callpoint and I/O unit.
Change Text.
Zone/device text can be modified directly at the panel, once the change text option has been selected
and either address, zone or panel text has been selected a list of the available zones/devices is
displayed on the panel. A qwerty keyboard is the displayed on the screen and with the existing text
above, typing on the keyboard then changes the text.
The address and zone text is limited to 25 characters which is the maximum that can be transmitted
over the network. Both are also restricted in the Site Installer program.
Amended: Mar 2013
Set Date/Time
FIG 10
The ‘Set Date/Time feature is a relatively simple and self explanatory method of setting the date and
However, if the panel is part of a multi-panel network, all of the clocks would need to be synchronised.
An extra button ‘Synch with master’ has been added to automatically synchronise the time with the
master panel, which in this case is always panel number 1.
Configure Zones
Following an Autolearn all devices are by default placed into Zone 1, if the Site Installer is available
then extra zones can be added and devices can be moved into the correct zone. If minor changes are
required then this can also be carried out directly at the panel using the configure zones menu.
Fig 11
Amended: Mar 2013
Input Programming.
Input devices are Detectors, Callpoints and the input side of an I/O unit which can be programmed on
the Site Installer to carry out different functions, (If un-programmed the default is Fire).
The Device Inputs box is opened by ‘right clicking’ on the individual device and when the device
options box opens then choose ‘Device Inputs’
This shows a device input box and subsequently how the panel is set to respond to each input option.
Selections can be made to make the panel reset, silence, evacuate, pre-alarm, fault or fire.
Other options include the disabling of a pre assigned group of addresses or zones (up to 8 of either see notes), or initiating the Day/Night or Non-Latch functions.
On a later release of Software and Site installer (July 2011) more selection have been added to the
input programming list to include – non-fire input, FRE only activate or Extinguisher only activate.
The input programming can also be used to turn on and off the feature T1/T2. When disable
addresses is used on the input and the isolate list is selected, all of the devices on the loop are
displayed together with a ‘Delay’ showing as the last device. This ‘Delay’ is T1/T2 which is disabled
when the Callpoint or I/O is operated and reinstated when the input is removed.
Non-latch is a feature where the panel goes back to quiescent state when the Fire situation clears,
this is particularly useful when interlinking with other panels.
1. The addresses must be on the same loop as the input device, whereas the disabling of
zones can be achieved across the panel.
2. The maximum number of Isolate lists allowed are 10 per loop i.e. 10 inputs set to
3. When disabling devices or zones the Non – latch button is not required.
4. Allow at least 30 – 40 secs from the end of a reset before returning the input to the
quiescent condition.
FIG 12
Amended: Mar 2013
Output Programming
Outputs are classed as Sounders/Beacons, I/O units, Sounder Control units and Shop Unit Monitors.
The panel is capable of accepting 120 outputs per loop, (60 Sounders set low) and 20 I/O units (each
I/O automatically takes three channels). Sounder Control and Shop units use sounder channels.
To set the device outputs right click the device, when the device options box appears choose ‘Device
The output device can now be programmed to respond to a specific trigger – globally, by zone by
address or by panel.
Each output can have three stages programmed – whatever is set in each stage that matches the
input trigger the output will follow (there is no designated hierarchy).
However, if the trigger is ‘Global’ in any stage this will always take precedence unless double knock is
also set.
FIG 13
If the sounder programming is to be the same for every device then hit ‘apply these settings to other
devices’ all of the sounders on the panel will be listed and ‘apply to all’ or apply to selected’ can be hit.
1. A delay can only be programmed onto Output 1 stage 1 of any multi-output device
such as a 3 chan I/O or a Sounder controller.
2. Double knock and delays need to be on separate stages.
Amended: Mar 2013
If the sounder trigger is by address, zone or panel then ‘allocate devices box can be used, the
allocate devices box appears and the trigger source can then be selected.
For example if this sounder is to operate only on a specific zone then that zone can be highlighted
and moved to the right hand box (up to a max of 16 per stage) and hit ‘ok’.
If there are more than 16 zones that need to be programmed to control an output, then the other 2
stages can be used to increase the allocated zones.
For example;
Stage 1 can have zone 1-16, stage 2 can have zones 17-32 and stage 3 can have zones 33-48.
The sounder will now only operate when a device in the selected zone goes into fire
FIG 14
Another feature within the output programming is ‘Any zone 2 devices’ when this is selected and the
allocate devices tab hit any zone can be placed in the right hand section. This will effectively double
knock the selected zone whereas that zone must have 2 devices in fire to initiate outputs.
Amended: Mar 2013
Zone Groups and DN any zone 2 devices
To further enhance the cause and effect programming options Zone groups have now been added
into both Site installer and the latest release software (JUL 2011).
250 Zone groups have been added to the system so that when any output devices trigger source is by
zone this now becomes by zone group.
Each zone group can contain up to 32 traditional zones and each output stage can be programmed
by up to 16 zone groups.
FIG 15
In fig 13 above output 7 is programmed to operate by zone group and zone groups 1,2 & 3 are
selected as the trigger source.
Amended: Mar 2013
FIG 16
Fig 14 shows that zone group 1 has 16 zones allocated (the maximum is 32).
FIG 17
The double knock any zone 2 devices has been radically improved – in the previous version only one
zone was allowed in the assigned zone groups.
In this latest version the number allowed has been increased to 16 zone groups and 32 zones within a
zone group.
Alternatively if NO zones are allocated in the right hand box ALL zones on the system would require 2
devices in alarm to satisfy this condition.

Further recent additions to both Loop software and Site installer allows the programmer to select extra
features on the output programming box
FIG 18
2 extra tick boxes have been provided; the first is used to tell the output device to follow any delays
set in the T1/T2 menus on page 12.
If left unticked this device would follow the normal program – this is particularly useful on a beacon
which is used to warn the operator of an alarm situation before T1/T2 has a chance to time out.
The second is used to exclude the particular output from an Evacuate command.
Evacuate command is used to override ALL output programming.
If, for example the system is part of a shopping precinct that send Evacuate commands to set the
outputs, then any zonal controls may be overridden, this box can be used to maintain any cause and

Sounder Settings
Globally, the sounder volume and tone can be set from the configuration menu described on page 11,
this could potentially cause issues if ALL of the sounders on the system were set to high volume.
Generally the sounders should achieve 65 dba or 5 dba above any likely background noise. The other
requirement is to wake a sleeping person where the minimum sound is required to be 75 dba at the
In this instance individual sounder volumes can be programmed through the site installer program to
prevent the panel from becoming overloaded. This is achieved by a right click on the individual
sounder and choose ‘sounder settings’.
Fig 19
Fig 20
This sounder (address 2) can now bet set to any of the required settings available. If All of the
sounders on this loop were required to be the same volume then choosing the address from 2 to 116
on this loop would ensure that all sounders in the range chosen would follow the settings in the boxes.
This method can be done for all loops on the program.
Amended: Mar 2013
FIG 21
This function allows new devices/zones to be added to the system.
When a zone is added then the panel uses the next zone number and adds it to the zone list.
When a new device is added then the panel asks which loop the device is connected to and the scans
the loop looking for a reply of 254, once this reply is received that device is allocated the next
available address location, this process is then repeated for the next device to be added. It is not
possible to add more than one device at a time as multiple replies of 254 would be received at the
same time and the panel would try to address them all with the same location number.
Once a device has been added then it will be placed in zone 1, it then needs to be assigned to the
correct zone and have text inserted. Sounders and I/O units can be added but on the older software
will not operate so these needed to be programmed by site installer. Version 2.4.25 addresses the
sounder issue but I/O’s are yet to be resolved. (The panel must receive a Watchdog reset for this to
When zones/devices are deleted then a list of available zones/devices is displayed and the one to be
deleted is selected and then the panel removes that zone/device.
When a Zone is deleted all devices in that zone are also deleted (a warning is displayed on the panel
to this effect).
If a device is deleted the panel returns the address number back to 254 enabling the device to be reused
Delete/Add Device cannot be used on address 1 of loop 1, the panel must ALWAYS have a
device at this point.
Amended: Mar 2013
Configure Heat Detectors.
FIG 22
When a heat detector has been auto learnt on to a loop the default setting is rate of rise.
If a fixed temperature setting is required then the detector must be changed via the panel menu
before the database is downloaded from the laptop computer otherwise when a check config is
carried out the there will be conflicts on all the heats that are set to fixed temperature on the laptop. If
this occurs and is left unmodified then the heat detectors will operate as rate of rise and may produce
unwanted alarms
Network programming.
When panels are networked together they each take a network address, this address is set up in the
engineering part of the menu along with the total number of panels that are connected on the network.
Panel 1 is automatically configured as the master such that if a network fault occurs the master and
faulty panel only will display the ‘Lon Network Error’.
When setting up a network for the first time after the network card is connected, the panel must have
a hard reset or power cycle to enable the panel to search for and recognise that a card is present. For
connection details see the ‘Networking section’.
On the network all fires, faults pre-alarms etc. are transmitted to all panels. All user actions such as
silence, reset and mute buzzer are also transmitted, so panel 1 could silence the alarms on all other
connected panels.
It is possible to individually configure the panels not to receive silence, evacuate and reset operations
from the network; this is particularly useful where the panels are installed in separate buildings such
as Student accommodation.
FIG 23
Amended: Mar 2013
If the network is such that all messaging needs to be turned off but certain panels need to
communicate directly with each other this can be controlled using the network filtering system where
individual panel messaging can be enabled/disabled across the network.
These features are found in ‘Network’ in the configuration menu.
Extra filtering has been added to enable the user to filter commands (reset, evacuate, silence, mute
buzzer) and Status messaging ( Fires & faults) across the network
FIG 24
Day / Night Settings
This is a function in the panel programming that allows certain devices to change their characteristics
dependant on the time of day. The devices that respond to this programming are the Heat detectors
and Photo thermal.
To program day night mode on the panel you add an input device and then on the input programming
menu you tick the day night box.
Then you go to either thermal or photo thermal detectors and on the input programming menu, you
tick day night mode.
When you tick day / night on an input unit you are controlling when the panel goes into and out of
day / night mode.
When you tick day / night on a detector you are instructing that specific detector to respond to
day / night programming.
1. The input unit in question must be either an I/O unit or a Callpoint.
2. If a 3 Chan I/O unit is used only channel 1 can be used for this function (the other
channels will put the panel to full fire.
3. The input unit must be on the same Loop Controller as the devices it is setting to
4. As soon as a Photo thermal has a tick against Day/Night the detector becomes pure
heat (A2S - Fixed Heat 60). Hence the Callpoint or I/O must be operated to return this
device to dual mode.
5. A half moon indication now appears on the screen between the supervisor button an
the clock when day night is in operation.

High Level Menus
FIG 25
Disable all Outputs
This menu enables the engineer to carry out a full test without any outputs operating. This function
can not be used with Weekly or Walk test features.
The outputs can be switched on and off from this menu, if however the outputs are inadvertently left
disabled when the engineer leaves site, the user can re-enable the outputs from the enable/disable
menu in 2214, or on later versions simply toggle the button in the high level menu.
On release version Jul 12 when all devices are enabled the panel will automatically ‘Hard reset’ to
ensure All devices are enabled.
Optical Detector Sensitivity
The sensitivity of the Optical detectors can be reduced by up to 70% to prevent unwanted alarms in
hot dusty environments such as the Far east and India. This feature is outside EN54 specs.
Amended: Mar 2013
Buzzer Disabled/Enabled
The Buzzer can permanently disabled using this feature, a disabled led will be displayed on the panel
and when interrogating the disable devices in the user menu, this will be shown as 1 I/O disabled.
Intermittent Fault Search
When a device goes into fault the panel has polled the detector a number of times to confirm the fault
(this is called integration), this can take up to 90 secs dependant on the length of the loop and number
of devices installed.
This feature forces the panel to indicate a fault on the first poll, which means the fault will appear
almost immediately.
This is particularly useful if a detector has an intermittent fault that would normally not be seen during
the standard polling sequence.
Generally this setting should be initiated at the commissioning stage.
This menu allows the engineer to change the Logo shown on the front screen of the panel
Customers can also download their own logo into the panel from the Commissioning menu
The logo must be configured as a Monochrome Bitmap (.BMP) 160 x 80 pixels.
FIG 26
Non Latching RF Faults.
With the addition of the Addressable and Conventional Radio fire Hybrid panels and the ability to
network Radio panels, extra features have been added into the menu structure to support these units.
One of which is the ability to select Non latching faults on the main panel.
Radio devices are highly susceptible to interference and blocked communications from various
sources and as such could go ‘Missing’ for short periods. These periods would generate faults on the
panel so could be classed as nuisance warnings therefore whilst still providing these warnings it
would be unreasonable to expect the user to have to reset the panel every time, so the RF ‘Missing
Address’ faults can now clear when the devices re-establish communications with the panel.
Tamper faults continue to ‘Latch’.
Amended: Mar 2013
Reset to Factory Settings
This feature will restore the panel to it’s factory settings, which on a programmed system is
catastrophic and not to be used lightly.
The panel will go into Autolearn – losing all programming. It will also re-calibrate the screen and put
the default logo onto the screen.
Sounder 1 & Sounder 2
This menu allows the conventional sounder circuits to be set to continuous or pulsing, delayed or
double knock
When the panel goes into Fire the word FIRE or ALARM can be selected to display this as part of the
indication on the screen.
Autolearn Locking
This feature has been added to prevent malicious or untrained personnel initiating an Autolearn once
the system has been commissioned.
Evacuate Locking
Evacuate, once initiated from the panel menu or a programmed input, can operate ALL internal and
external outputs connected to the loop. If the panel is controlling critical systems requiring a double
knock scenario such as a Gas release system this could be immediately overridden by the evacuate
In these instances evacuate would be considered inappropriate, therefore, evacuate can now be
locked to prevent it overriding critical programming.
Activate on Evacuate
FIG 27
This feature allows the user to further filter what is required to operate when Evacuate is not locked.

Australian FB Screen
This enables the screen to show Zone or Address text when in Australian mode (see page 13)
UL 864 9th Edition
This is an additional feature to enable the panel to be operated in areas where UL is specified.
Essentially the panel remains the same; however, there are a number of differences in terminology
and minor changes to internal software.
Disablements are now displayed as Supervisory warnings, Faults become Troubles.
Sounder circuits become Notification appliance circuits (NACS) and the Loops, Signal line circuits
The Mute buzzer is acknowledge alarm and as a UL requirement, the buzzer also re-starts after 8
hours if the panel is not reset.
The Callpoint is now a Pull Station.
Earth trouble (fault) now has a separate led indication as well as information on the touch screen and
buzzer sounding.
T1/T2 remains the same feature but is now called ‘Positive alarm sequence’.
Alarm Verification has been slightly enhanced to provide 3 time scales 15, 30 and 60 secs
Daylight Savings
FIG 28
Daylight saving mode which would normally be set for the UK market can now be disabled in the high
level menu.
Amended: Mar 2013
BS 5839 Button
This button has been added for when there is significant cause and effect programmed into the
system but the outputs need to meet BS5839 specification.
FIG 29
This means that when selected and a Callpoint is activated, the sounders will operate within the 3
seconds required by BS overriding any sounder cause and effect. However, the remaining cause and
effect for output devices will only follow when the time to process this is available.
Local Zones ?
Generally UK networks use global zones where all zones for the whole network appear on all panels.
In this case if a shared zone on 2 panels were put into test then the zone would be in test on both
Most European networks would not be configured in this way for example on a 3 panel network
Panel 1 would have 1-5 zones, panel 2 would have 6- 10 zones and panel 3 would have 11-13 zones.
This feature has been added so that when selected local zones are displayed on the panel screen.

Test Fires Activate fault relay.
This feature was provided so that when connected to a shopping mall the main operator needed to
know when a test was been carried out by individual shop units. During a weekly or walk test the fault
relay will change state to warn the centre that a test was in progress rather than a true fire.
Abnormal Comms Detection.
Abnormal comms has always been monitored within the loop code, however when any abnormal
comms is generated by raised background current this will generate a fault on the panel. This is a
requirement for EN54 part 13
Fast Automatics.
The introduction of a more robust response to electrical noise on the loop wiring has slightly slowed
the response of smoke detectors on larger loops. Whilst still within the requirement of EN54, fast
automatics have been introduced to provide an interrupt to speed up the response to an alarm
Opto Fire and Fault Threshold override.
The thresholds for fire and fault are defaulted to 60 and 10, these two buttons can be used to lower
these thresholds down to 53 and 3 respectively.
FIG 31
Global Weekly Walk tests
If the panel is part of a Network, the customer may require the weekly and walk tests to be transmitted
across the network – this is defaulted to activate the local panel only.
This feature allows the customer to globally test the system.
Amended: Mar 2013
Conventional Sounder Local fires
Under normal circumstances if loop sounders are used on a system these can be programmed
through the Site Installer to operate on the local panel.
The conventional sounder circuits do not have that level of control in the Site Installer and therefor
react to ANY fire anywhere on a network. To that end a measure of control has been added so that
the conventional sounders will only sound when there is an alarm situation on the panel they belong
Pulse Buzzer on Disables
In normal circumstances the buzzer will sound when any disablement is put onto the panel. This is a
requirement of EN 54 and UL 894, however in certain countries, this is classed as a nuisance warning
so the facility for disabling the buzzer on a disablement can be removed using this button.

The network can be wired as either a Loop or a Radial. If Booster devices are used the system must
be run as a Radial
The maximum cable length before Boosters are used is 1000m.
The Terminator resistors are fitted across the network to smooth out the signal. The network requires
51ohms across pos & neg when checked at any card on the network, This can be achieved by cutting
off or soldering on resistors as required. (See Figs 32, 34, 35, 36 & 37)
On the later version network card this process has been improved by selecting the switches provided
on the PCB for loop topology or radial (bus) and terminator in or out.
NOTE Connection details on the terminal block are not polarity sensitive.
Cable Types
The recommended cable for the network connection between panels is an enhanced cable
manufactured by Draka Cables (Pt No 910234). Screen continuity must be maintained throughout the
entire network circuit including each junction point.
The screen should only be earthed at the connection point at the first panel and not at any other point.
The screen or drain wire of the network cable should not be considered as a safety earth and
therefore should not be connected to the terminals marked with the earth symbol, except at the panel,
and should not be insulated with green/yellow sleeving.
Where the network passes between buildings, screen continuity should not be maintained from
building to building. A Booster device must however be used irrespective of cable length and should
be fitted at a suitable point in the link between buildings. The screen should be connected to the earth
of one panel in each building.
The L-Switch Booster is made by a firm called Loytec, and works on a supply voltage of 9-35 v DC.
This means that the Easicheck or DF6000 panel external 24v output can power this device.
The Booster has two modes of operation ‘Smart Switch mode’ and ‘Configured Router’, for all
applications we use the former mode. In this mode the device automatically detects the bit-rates of
the connected channel, copies the information detected on the network and forwards it to the next
network card.

Ancillary Devices
Standard devices include Photoelectric, Ionisation (which will be obsolete by Dec 2007), Multimode
heat and the replacement for the Ion, the OptoThermal.
The heat detector defaults to RoR when the panel is in Auto learn, these must be set to the required
value RoR, BS (fixed 60 deg) or CS (fixed 78 deg) before upload or download to the laptop.
The OptoThermal has both an optical smoke chamber and a heat element that work in tandem such
that the smoke half becomes more sensitive when heat is also present.
Each element will also work independently such that the heat is fixed temp 60 deg (A1S) and the
optical has slightly reduced sensitivity (but remains within the tolerances laid down by EN54).
The OptoThermal and heat detectors are capable of responding to Day/Night programming described
on page 27
Call points
Call points are supplied as Surface, Flush mounted and IP 67 Weatherproof. Various accessories can
be fitted such as the hinged protective cover, recessing bezel and resettable plastic element.
Generally the inputs of this device are used primarily for Fire, but the Input programming in Site
Installer gives the options of setting them to fire, fault, reset, silence, pre-alarm and evacuate.
A call point can also be used to initiate day night mode, isolate addresses or zones or be set to nonlatching.
Sounders, beacons, sounder beacons all appear on the DF6000 device list as alarm/beacons and a
maximum of 60 are allowed per loop, the panel and site installer treats them all the same for
programming purposes.
The site installer allows 3 stages for the device outputs and various options can be chosen at each
stage. Delays can ONLY be used on stage 1. (There is NO hierarchy on the stages whichever setting
fulfils the requirement the sounder/beacon will comply with that setting)
The settings i.e. sound or volume for the sounders can be done globally at the panel or individually on
site installer.
Input/Output Devices
MIO1240 is a single input single output device. The output takes the form of a mains rated relay
capable of switching up to 8A.
The Input spur is used to monitor a set of volt free contacts the end of line being 22k and a firing
resistance of 5k6.
Programming of the output has the same features as the sounder outputs. The Input programming is
the same as programming for the call point.
Amended: Mar 2013
MIO324 is a 3 channel I/O (3 separate inputs & 3 separate outputs) that only takes 1 address. The
outputs are three relays capable of switching 1A at 30v.
The 3 input spurs have the same function as the MIO1240, 22k end of line, 5k6 firing resistor.
Each channel is individually programmable both for inputs and outputs in the same way as the
Because this device only holds 1 address there is no way to apply text to the individual channels.
This unit contains the same restrictions concerning delays – which can ONLY be programmed
on stage 1 of output 1
This unit is identical in build to the MIO 324 but this has been designed to take 3 addresses (this can
be expensive in terms of outputs because it replies as 3 x 3Chan I/O’s), this means that text
information can be allocated to each channel. It also allows each individual input and output to be
disabled (by address).
Once again this unit is identical with the MIO 324 only taking 1 address. The programming is the
same as the MIO 324. This unit was designed so that the relay outputs reset on silence rather than
full reset.
This unit is a Mini output unit providing switch contacts only, rated at 1A 30v. There is no input on this
unit. This item replies as an I/O unit so takes 1 of the 20 I/O’s allowed per loop.
Identical to the above but this unit is programmed to reply as a sounder, the relay contacts on the
MCOM/S change state on reset, the UL version resets on silence. These units have been created to
enable more than the 20 relay outputs per loop by sacrificing the total amount of sounders allowed.
Note – The MCOM/S unit must be programmed using site installer - the contacts DO NOT
change state in Autolearn
This unit is a Mini input unit capable of monitoring volt-free contacts in other fire panels, sprinkler flow
switches etc. It replies as a I/O unit and therefore will take 1 of the 20 allowed per loop. End of line
resistance is 22K the firing resistor being 5K6.
The MCIM/C is identical to the above this unit replies as a Callpoint so accommodating up to 200 per
loop. The response time of operation has also been modified to operate in the same way as a
Callpoint, so this item will put a fire on the panel quicker than a standard input generated from an I/O
The MCIM/NF is a Non-Fire input and is identical to the MCIM and MCIM/C. This has been
programmed not to indicate a FIRE condition on the panel when in alarm.
Loop outputs can be programmed to respond to this device without the need to create a fire condition
on the panel. The panel outputs DO NOT respond to this input.
This new device replies only as an Input number - allowed 200 per loop. It has been introduced to
replace all of the above inputs and is programmed on Site installer for various functions as shown.

Zone Monitoring Units
MIU 871
This is a true Zone monitor with 2 inputs, one for a zone of conventional call points the second for a
zone of conventional detectors (max 20). End of line for the call point zone is 6K8, end of line for the
detection zone is the EOLM 1 (the JSB FXN 520 series can only be used on this zone).
MIU 871/IS
Similar to the above but the detection zone has been programmed to accept a Zener barrier and zone
of intrinsically safe detectors. End of line for this zone now becomes 6K8 and the diode in the detector
base must be removed.
This device has been programmed as a Technical input similar in effect to the Non fire input. This
device can be used in conjunction with a Fan controller, and can be used to provide confirmation of
operation (feedback) from an extract fan or smoke vent.
MSU 840
Another zone monitor similar to the MIU 871, this unit also has a fire relay rated at 30v 1A and 2
conventional sounder circuits fully monitored. The power supply, which is also monitored, is the FX1A
and must be fitted even if the sounders are not used.
MSU 840C
This device provides the output to control an extract fan or smoke vent in conjunction with a Fan
control unit.
Fan Controller FC6
The FC6 Fan Controller is designed to satisfy the requirements of Australian standard AS1668 & can
be connected to a Cooper analogue addressable fire alarm control panel by means of the comms
Loop utilizing only one address.
There are 6 channels per Fan Controller capable of controlling & indicating 6 individual Fans.
Each channel is programmed to an output device and feedback input device in the loop (for example,
MSU 840-C, MIU871cUK modules) to control & monitor the status of the Fan.
A new module has been created which provides 2 addresses the first to control the feedback the
second to provide output and reset controls for the fan
In Automatic mode the Fan is controlled by the DF6000 in the normal way through the site installer
program. Feedback must be detected from the Technical input within 25 secs or a fault will appear on
the FC6
In manual mode the Fan can be started and stopped using the Start/Stop buttons on the FC6, again
once the start button has been operated then feedback must be received within 25 secs.

4 Way Sounder Control Unit (MPU 424)
The MPU 424 is designed to accept 4 conventional sounder circuits with a total rating of 3.2A spread
equally over the 4 outputs. This unit takes 1 address on the DF6 system and has its own power
supply and battery backup.
Each individual circuit can have the same programming as a single loop sounder output.
The only criteria being that a delay can ONLY be put on stage 1 of channel 1.
Because the loop output devices cannot be programmed for fault, the MARDF6 was designed to
provide a fault relay with dry contacts for use with an Autodialler or Redcare that requires a fire and
fault signal.
This unit connects across the FRE or FPE outputs and the Fault output. The internal 24v supply in the
panel powers the unit.
Spur Isolator- MSI850
This unit is designed to accommodate a Spur of addressable devices but does not take an address
itself. If the unit is installed at the outset the panel autolearns up to this device autolearns the spur and
then carries on with the remainder of the loop. The spur isolator can also be added after the panel has
been autolearned but any devices on the spur MUST be added ONE AT A TIME.
If all devices are run off a number of Spur isolators, then one single device MUST be fitted on
the loop between the last isolator and the return run to the panel. (If this is not done then
‘Short circuit far’ will be displayed on the panel)
Beam Detector MAB50/100R
The reflective beam detector uses one address on the system. Initially the unit is autolearned and
then aligned using the Dill switches on the rear of the unit.
The device mode switch is set to run mode by default and the detector will not learn to the
panel if set to any other position.
Set the 3-position switch is set to position 1 ‘Prism target Mode’ align to the prism using the
thumbscrews. Once the prism has been correctly targeted the prism MUST be covered to ensure the
device is not receiving reflections from other sources.
Set the switch to position 2 ‘Alignment Mode’ and fine-tune the alignment using the thumbscrews.
Finally, once fully aligned, set the switch to position 3 ‘Run Mode’ and reset the fire panel
Repeater panels can either be Loop connected taking one address in the number sequence, or
connected via the network, in which case the repeater will be fitted with a Network card.
The loop repeater has functionality limited to sound/silence alarms or reset the system. The internal
buzzer can now be muted from the main or a networked panel (added Aug 2010)
The supervisor access code (2214) can be disabled or changed using the engineer menu (2132).
The Loop repeater must have the same text downloaded into it as the main panel it is connected to.
This is achieved by connecting the laptop to the repeater using the same download cable as the main
panel, using the engineer code to ‘Download DF6000 text’.
This text information is stored in the Display pcb, whereas the device address is stored in the Psu

These mimics are configured as a master board and slaves to create up to a total 250 outputs.
The master board takes the loop address and all slaves are connected to this.
Each one must have a 24v supply.
The 250 outputs are configured within Site Installer by applying rules to each output.

Addressable and Conventional Hybrid
The addressable and conventional Hybrid devices sit on the wired loop of the DF6000 as 1 address,
up to 32 wireless devices can then be associated to the device.
The addressable hybrid acts almost as a Spur isolator allowing a zone of addressable devices to
show as individual addresses on the main panel, whereas the conventional hybrid, acts as a zone
monitor with devices associated to it but not showing as individual addresses on the main panel.
The commissioning of the devices on to the Hybrid has 2 steps; the first is to set the panel into the
correct mode in the commission menu shown below by selecting ‘Commission devices to hybrid’.
Once in this mode open the hybrid and lower the front door to expose the 3 controls.
FIG 41
There are 3 controls on the interior of the Hybrid, ADD, DELETE and SYNCH.
The ADD allows the user to commission individual devices to the hybrid. This is achieved by selecting
the button once and the green Led will illuminate, selecting add a second time will cause the green
led to pulse quickly (this means that the hybrid is entering commissioning mode). After a short time
the green Led pulse will slow to about 1 per second at which time devices can be commissioned to
the unit. This is achieved by adding the batteries to the Radio device.
After about 15 seconds the green Led on the hybrid will go to continuous for a few seconds and the
red Led on the device will also illuminate for a short period to indicate that it has associated with the
The green Led will go back to a slow flash awaiting the next radio device to be powered.
Once complete the add button can be pressed again – the green led will flash quickly for 10 – 20 secs
and then extinguish.
The main panel can now be returned to normal mode and maintenance Autolearn initiated. The Radio
devices will be placed at the back of the loop number sequence.
The DELETE button when pressed once will cause the red led to illuminate, a second press will cause
the led to flash quickly, which will then flash slowly after a few seconds during which time ALL of the
devices on the hybrid will be decommissioned. Once this process is complete the red led will

it finds any it will illuminate the led steady and then continue with the search until the synch button is
pressed again to extinguish the led and stop the search.
If there are a number of hybrids one must be set to master and the other to slaves using the jumper
J2 on the pcb of the hybrid.
Following the maintenance Autolearn the program can be extracted from the panel using the latest
Site installer version

Getting Started & Fault Diagnosis
Powering the panel.
When the panel is powered up it will go through a boot up sequence and will test all the display LEDs.
The touch screen should be illuminated and show the normal front screen. If that does not happen
this section details common problems and methods of fixing the problem.
Panel takes a long time to start the boot up sequence after a
watchdog reset (or power up).
On 4 loop panels (with 2 loop driver cards) there may sometimes be a long delay in watchdog. The
following steps will speed up a reset.
Place a jumper link on a loop driver (2 pins near crystal).
The panel will reset and the relay click will be heard 4-6 seconds later.
Remove the jumper link from the loop driver card.
IMPORTANT the jumper link must not be left on a panel once it is booted up.
Power LED not illuminated
If this happens, the display PCB is not getting power. The following steps should help identify where
the fault is.
Always power down the panel before disconnecting and connecting any PCB wires or cables.
Refer to DF6000 Motherboard drawing
First confirm the PSU PCB is working correctly. Disconnect the red multiway connector from the PSU
and mother board, check it’s continuity.
Check the voltage on the battery connectors, this should be around 26V. If this is lower check the
battery fuse – replace as necessary. If the fuse is OK, then the PSU PCB needs replacing.
Power up the PSU and carefully check the +26V and +26Vraw connectors are at around 26V, if they
are power down the PSU and reconnect the PSU to the motherboard by the red connector.
Next confirm the motherboard is working. Disconnect the ribbon cable, loops etc. only leave the
connection to the PSU. Find the test points on the Loop motherboard PCB check +26V, +26Vraw and
also Vcc (should be 5V). If any are low check the PCB for any contamination shorting on the board. If
this doesn't clear the problem replace the motherboard.
Next connect the display ribbon cable only. Check the Vcc on the motherboard and the display board.
If it is 5V on the motherboard only replace the ribbon cable. If both are low check the display for
Replace the micro board and display board separately to locate which is faulty.
Power LED on but touch screen is not illuminated
Connect a PC using panel comm. When the panel is reset debug code should be shown on panel
comm, if it is the following should fix the problem.
Ensure the connector on the inverter is securely in position.
Ensure the micro board is securely connected to the display board.
There are two 5V regulators on the motherboard, check both Vcc and 5V backlight are at 5V, if not
replace the motherboard, if they are replace the display board.
If the panel does not respond on panel comm, ensure the micro board is connected to the display
PCB securely. Otherwise replace the micro and display PCBs.
Amended: Mar 2013
Power LED and touch screen illuminated but no text visible
When the panel is powered down the touch screen needs a minute to reset. Power the panel down
and disconnect the batteries for 90 seconds, then re power the panel. If this does not work connect
panel comm and press the reset button. After a few seconds the PC should show debug code
scrolling on the panel comm application. If it does not show debug text, ensure the micro board is
securely in place.
If there is still no debug text the micro board or display PCB may need replacing. If debug text is
shown on the PC the contrast may need adjusting on the micro board or either the micro board or the
touch screen may need replacing.
Screen is visible but touch screen does not respond to touch
Ensure the touch screen connector is in correctly.
Ensure the micro board is securely attached to the display board.
Send '7' from a PC to the panel to start the screen calibration routine.
The touch screen works and is correctly calibrated but I cannot get
to the supervisor entry screen.
The panel may be in Swedish mode. If this is the case then to get access to the menu system the
class change input needs to be momentarily shorted.
The access code entry screen will now be accessible.
To disable Swedish mode on the panel, use the engineer level access code, select configure >
program I/O’s and sounders > Auxiliary board. Swedish mode will be selected, press not required
then exit. The panel will now behave correctly.
The general disabled LED is illuminated
If this occurs something is disabled on the panel or a time delay has been programmed on the panel.
To clear this use the 'enable all' button from the enable/disable menu in the supervisor access level.
An alternative method, provided a delay has NOT been programmed then go to the enable disable
menu and instead of enabling all devices, go to enable disable I/O, and then disable the delays.
Amended: Mar 2013
Check the loops with a multimeter
Auto-learn the panel
Upload to a PC (Optional)
Download from a PC
Check auto-config
Run Intermittent Fault search
Test the devices
Loop Checking with a multimeter
The first quick test that should be done on all the loops is to check the continuity of the loops using a
The resistance should be measured start positive to end positive, start negative to end negative, and
positive to negative at the start and end of each loop.
The resistance along the positive line should be less than 50 ohms. The resistance across the
negative line should be 2k5 ohms for each device on the loop, e.g. 20 devices should measure 50k
The resistance across the loop positive to negative will be in the Mohm region.
Ensure the screen is continuous around the loop, this reading should be approx 10 ohms.
The screen should not be bonded to building earth.
Test the loops with the multimeter set to AC volts – this is to check that there is no induced voltage
which could be caused by the cables being run too closely to a high voltage source.
This will show if anything drastic is wrong with the loop devices wired in backwards breaks etc. If
there is a short at the end or start of the loop this will need to be fixed before powering the panel.
Amended: Mar 2013
Auto-Learn Function
This is accessed through the engineer level access code. When the panel is auto-learned all the
devices address information is set up from address 1 upwards from the start of each loop, previous
addressing is lost. Once the panel has finished the auto-learn it will reset itself. After this is done reset
the panel using the touch screen.
The panel should now display system healthy, the following are common faults and solutions:-
“Dual address”
The panel shows this fault if two or more addresses are responding at the same time. The most likely
causes would be:Device wired incorrectly. See wiring diagram for the device
Base switch not opening. The switch on the base can occasionally be pushed above the metal tab
preventing the switch from opening. See diagrams below.
FIG 50
If this is the case the switch may need to be clicked under the tab, if this fails the base may need
Amended: Mar 2013
Detector not correctly inserted on base. If a detector is not fully inserted onto a base it is possible that
the base switch will not be opened. The newer detectors and bases have a tab to show when the
detector is fully inserted. See diagram below.
FIG 51
Base sounder device not wired correctly. When a detector is inserted onto a base sounder there is not
much room behind the detector. If the cabling is not cleared from the base, see images below.
FIG 52
The detector may be pushed away from the base preventing the switch opening, or crushing a contact
and thus not receiving power.
Spur isolator wired incorrectly. See wiring diagram for spur isolator.
Amended: Mar 2013
“Open circuit” Positive/Negative.
This means after the auto-learn the panel has detected a break in the positive or negative line. The
most likely causes would be:Device wired incorrectly. See wiring diagram.
Base switch opening but the detector not making contact. Ensure the base contacts are correctly
screwed down, and none are damaged. Then ensure the detector is replaced correctly.
A negative break may also be caused by a short at a device in the middle of the loop that the loop
device isolators have detected and dealt with. See short circuit middle below.
If the loop voltage drops (below 18 vDC) the devices may reset causing an open circuit negative.
(There must not be more than 2Km of appropriate properly earthed cable used per loop.) If a faulty
device is suspected it can be seen by linking the loop in the panel and disconnecting the far end of
the loop, see diagram.
FIG 53
Measuring the voltage across the end of the loop for correct function this should be over 15V (usually
over 18V). If the panel is left in this state the end devices will go into fault. The faulty device should be
one of the active devices.
Amended: Mar 2013
“Short Circuit” start or end of a loop.
There is a short at the start or end of the mentioned loop. The fault can only be on the panel. The
first/last device or the wiring in between the panel and the device. This prevents the loop driver from
functioning and must be fixed in order to auto-learn the panel. Common causes would be:Either the first or last device is wired incorrectly.
The loop connections into the panel are wrong.
Something is shorting on the PCB.
No device between the last Spur Isolator and the panel
If the initial loop test didn't show a short across the loop power down the panel and remove the loop
Measure the resistance across the loop using the appropriate terminals, If this is still in the Mohm
region change the loop driver card. If this is short circuit recheck the loop by disconnecting the loop
and measuring.
If this is Mohms change the motherboard.
“Short circuit middle”
Device wired incorrectly. See wiring diagram.
Device is drawing too much current. A faulty device may draw too much current and be detected as a
Replace the device.
“Fault at address”
There are several possible causes of faults at individual addresses, the panel may show more
information (e.g. which channel for 3 channel IO) or may show analogue value for the fault:Device is missing, unlikely after an auto-learn as a missing device wouldn't have addressed. Incorrect
earthing may cause this. This fault would have an analogue value of 0.
A repeater, sounder control unit have their own power supply if the PSU is not on and there is no
battery, the device will show a fault, analogue value 0.
Detector low analogue value fault. If the detector shows analogue value of 1 the detector may need
replacing or cleaning.
End of line resistors not correct. IO units, ZMUs etc. have end of line resistors. If they are not wired
correctly the panel will show a fault at this address but will give specific information (ZMU detector
zone etc.) about the fault.
Amended: Mar 2013
“Earth Fault”
An earth fault may be associated with other faults or random fires.
This should be cleared before trying to sort out these other faults as it may be the root cause.
Power down the panel, disconnect all loops, sounders and relay connections. Ensure the panel is
correctly earthed.
Check the +ve & -ve cables to screen/earth, ensure greater than 1 Mohm. Check that the screen is
not tied to building earth.
Repower the panel if the fault remains with the cables disconnected, examine the Pcb’s for
contaminants or shorts.
“Sounder 1 or 2 Fault”
This is a fault on one of the two conventional sounder channels. Common causes would be:One of the fuses has blown.
End of line resistor not fitted.
Sounder wired incorrectly. See wiring diagram.
Sounder circuit is shorted.
“FRE, FPE, Fault relay Fault”
These are the other panel outputs, faults on these could be:End of line resistor not fitted.
Output line is shorted.
The panel goes into fire straight after auto-learn.
This can be caused by the following:Dual addressing, causing the panel to interpret a signal as fire.
This will show itself if there is a dual address fault at the same address as the fire (it will take longer
for the fault to show than the fire).
Device triggered into fire, detector reading high analogue value, call point with glass broken or not
correctly fitted. The panel should show a fire at an address and the LED should be on at that address.
Silence the panel, check the address that is in fire. When the problem is fixed check the analogue
value using the commission screen on the engineer level access.
Amended: Mar 2013
The panel constantly resets after auto-learn.
This is a specific dual-addressing fault. Certain combination of devices dual addressing may cause
the panel to think they are a repeater and respond to the responses by constantly resetting. The
following steps should be done to remove this problem.
Remove the loops from the panel, the panel will stop resetting.
Go to the delete device menu in the engineer menu and delete all the repeaters from the panel.
Reconnect the loops, the panel will not reset.
Locate the dual addressing devices (see below to locate a fault) and fix the problem.
Auto-learn the panel, it should no longer reset, if it does repeat the above and locate any further dual
addressing problem.
The panel fails to auto-learn past a device
This may be seen with short or open circuit on the loop, the problem will probably be located at the
last device detected or the next one along. See the above on open circuit positive/negative.
If there is no associated open circuit the device may be faulty, link out the device after the last one
auto-learned and try again. If this fails link out the last device detected and auto learn again. If either
device is causing the problem replace it.
Once the faults have been removed from the panel and it shows system healthy after a reset go to the
system details screen and check the numbers of devices on each loop is the same as what has been
installed on each loop (spur isolators do not show on system details). If this number is less than
expected the following may be the cause:If spur isolators are fitted the spurs may not be correctly installed. To check this do test device on
what should be the last device on each spur (see locating a fault below), if the incorrect device LED is
on work back along the spur with test device until a device is correctly identified. The problem may be
that device or the next one along the spur, see open circuit negative/positive above.
If no spur isolators are present or the spurs are all working ensure the site devices have all been
connected to the loop.
Locating a fault on a loop
If the fault is a short circuit middle or a open circuit on the loop the check auto-config function can be
used. This is in the supervisor level on the others section of the display. When this function is used
the panel will go round the loop from the start until it cannot communicate with a device it will then
show an open circuit at an address, this will help locate a short/open circuit in the middle of a loop. If
check auto-config shows a fault at the end of the loop but no short or open can be found, the problem
may be a resetting detector, see 'loop voltage drop' above in “Open circuit” Positive/Negative section
above. Alternatively run the Intermittent fault search in the high level menu.
If an address is suspected as been faulty or dual addressed the test device function can be used to
locate the device. Test device is in the engineer level under testing. When a device is put into test its
LED should light up, two will light up if both devices have the same address. If the tested device is a
sounder it will sound continuous. Sometimes the faulty device will not respond if this is the case test
the device before the faulty one and the one after the faulty one to help locate the exact device.
Amended: Mar 2013
Other Faults
Charger Fault
This will show if the charge current is too low. Possible causes for this are:The charger fuse has ruptured.
The batteries are disconnected.
The batteries are damaged.
Battery Fault
This will show if the charge voltage is too low. Measure the float voltage at the battery terminals, it
should be around 26V depending on how charged the batteries are. This could be low if the batteries
are damaged, replacing the batteries should clear the fault.
Mains Fault
If this is the only fault on the panel the LCD back light will be off. Touch the top left of the screen to
light the screen. The panel will only run on batteries for one or three days depending on it's
configuration. When the mains returns the panel will need resetting to clear this fault. If the fault
returns after a reset check the mains input.
Error Codes
The following are a list of error codes that may appear during the boot sequence of the panel.

Programming Issues
Once Autolearned, the panel will work as a basic fire alarm provided there is no cause and effect
required on the site.
The panel, however, can transfer this learned information to the Site Installer program on a laptop,
where full zone and address text can be programmed together with different relay outputs, sounder
settings etc. and any Input programming to fulfil any customer requirements.
NOTE Programming, when completed must be in conjunction with total numbers and settings
laid down in the previous sections of this guide.
Once programmed, this information can then be returned to the panel.
A number of issues have been identified:
1. If the program will not go back into the panel, this is likely to be corrupted or incorrectly set up
or the display micro (CDR) is corrupt. Power down the panel and remove the loop driver
cards. Power the panel again and carry out an Autolearn (this effectively clears the CDR).
Power down again and install the loop driver(s), re-power and try to reload the program. If this
will still not download then check the program or replace the micro.
2. If after successful download the panel goes into random fires – this is almost always due to
an incorrect program. (or the wrong program for the site).
3. If after successful download, and during testing various sounders do not operate. This could
be due to too many zones being programmed for each sounder stage (max allowed is 16).
4. If after successful download, and during testing sounder begin to stop operating. This could
be due to the sounders being set to too high a volume and hence taking too much load.
Check sounder settings and turn down the volume if necessary. If this is not the case check
the hardware Revision number on the reverse of the Loop driver, ECN818 is the latest version
that delivers better load performance than the previous(ECN651).
5. If after successful download the panel display no faults, but the front screen says ‘System
Healthy 0 Zones Active’, this is associated with a networked system. Following a download
the panel address and number of panels in the network can sometimes be returned to 1. Go
into the commissioning menu and set up the network address and total number of panels in
the network.
