Overview & General Description
2.1
Introduction
The FIRECLASS Prescient III Gas Extinguishing
Control Panel is a stand-alone panel intended for use
with gas extinguishing systems. It has been designed
and approved to the European Standard EN 120941:2003, as well as the relevant parts of EN54-2:1997 &
EN54-4:1997. The FIRECLASS Prescient III panel also
incorporates the relevant recommendations of the British Code of Practice BS7273-1:2000.
The FIRECLASS Prescient III is fully compliant with the
mandatory requirements of EN54-2 and 4 along with the
following options with requirements:
1 EN54-2:1997 Clause 7.8 Outputs to fire alarm
devices (sounders).
2 EN54-2:1997 Clause 7.9 Outputs to fire alarm
routing equipment.
3 EN54-2:1997 Clause 8.9 Output to fault warning
routing equipment.
4 EN54-2:1997 Clause 10 Test condition.
The FIRECLASS Prescient III provides the following
compulsory functions of BSEN 12094-1:2003 as listed
in clause 4.3.2:
1 a) Reception & processing of at least one input triggering signal from an f.d.a.s. (Fire detection Zones 1
& 2) and an input triggering signal from manual triggering device(s) connected directly to the e.c.d.
(Manual Release input).
2 b) Transmission of the extinguishing signal (Actuator
circuits 1 & 2)
3 c) Activation of Alarm devices (Extinguishing
Sounder circuit)
4 d) Indication of each condition unambiguously (LEDs
& internal buzzer).
5 e) Transmission of the information of the incorrect
status of components and of the information of the
fault warning condition (Fault Signal Output).
6 f) Transmission of the information of the released
condition (Gas Released Output)
The FIRECLASS Prescient III provides the following
optional functions of BSEN 12094-1:2003 as listed in
clause 4.3.2:
1 g) Extinguishing system delay.
2 h) Reception of a signal representing the flow of
extinguishing agent (Discharged).
3 i) Monitoring of status of components:
– Low pressure/low weight
4 j) Reception of signal from an emergency hold
device.
5 k) Separate monitoring of the status of non-electrical
disable device(s) (Isolation valve).
6 n) Input from auto/manual selector switches.
8
7 o) Transmission of a triggering signal to equipment
within the fire extinguishing system:
b) Optical warning devices (Status indicators).
8 p) Transmission of signals to equipment outside the
fire extinguishing system (Shut downs).
9 r) Reception of signal from an emergency abort
device.
10 u) Activation of alarm devices with different signals.
(2-stage sounders).
The Environmental Class as defined by clause 4.2 is:
Class A: temperature range -5 to +40 Deg C.
The FIRECLASS Prescient III is fully compliant with the
relevant recommendations of BS 7273-1:2000. The following safety critical aspects have been addressed:
1 6.1.2 Avoidance of accidental discharge.
2 6.4.3 A single short circuit in connections shall not
cause an extinguishant release.
3 6.4.4 Protection against over voltages which could
cause an extinguishant release.
The FIRECLASS Prescient III integrates the functions of
a fire alarm system and a gas extinguishing system. The
FIRECLASS Prescient III monitors one extinguishing
area and one non-extinguishing area for fire conditions
and gives an appropriate audible and visual indication.
Zones 1 & 2 are used for coincident detection in the
extinguishing area and can be used to automatically
release the extinguishing gas. The Auxiliary zone only
provides an alarm indication. The FIRECLASS Prescient
III also provides a facility for initiating the release of
extinguishing gas manually.
The FIRECLASS Prescient III incorporates with a 5 Amp
switch-mode power supply with Power Factor correction.

3.1
Detection Zones (ZONE 1,
ZONE 2 & AUX ZONE
Three detection zone circuits are provided. They are
monitored for Open Circuit Fault, Short Circuit Fault and
Alarm (Fire). The End-Of-Line device is usually a 22 uF
capacitor (or 10 kΩ resistor if set to Intrinsically safe
mode) but can be configured for 3.9 kΩ resistor via a
DIL switch on the motherboard.
A maximum of 32 devices may be connected on each
zone (the actual number is dependent on the type of
detector used, see section 5.4).
Manual Call Points may only be connected to the aux.
zone.
In Automatic mode, zones 1 and 2 are normally used
together to produce First Stage (pre-activated) and Second Stage (activated) fire alarms, resulting in automatic
extinguishant discharge ("Double Knock" Zones).
The auxiliary detection zone only provides a general fire
indication.
Operation of Fire Reset causes the power supply to all
three zones to be disconnected for 4 seconds to reset
any activated detectors.
The Display Board has Fire and Fault LEDs for each of
the zones.
The Display Board also provides User Controls for disabling the monitoring of individual zones.
3.2

3.9 Remote Inputs
3.9.2
Gas Trapped (GAS TRAPPED)
This is a fully monitored input, providing open & short
circuit fault monitoring. The EOL device is a 10 kΩ resistor, activated by a 680 Ω resistor. Activation illuminates
the HOGE DRUK VERZAMELLEIDING LED and raises
the general fault condition.
The inserts can then be cut out and inserted into the display board.
3.9.3
Low Pressure Fault (GAS LOW)
This is a fully monitored input, providing open & short
circuit fault monitoring. The EOL device is a 10 kΩ resistor, activated by a 680 Ω resistor. Activation illuminates
the LAGE DRUK GASCILLINDERS LED and raises the
general fault condition. An open or short circuit fault is
indicated by the Blussturing Storing LED on the
display and a Gas Low Fault LED on the motherboard.
The input is configurable for normally open or normally
closed operation via a DIL switch on the motherboard.
3.9.5
Extinguishing Isolation Valve
Status (ISO. VALVE)
This is a fully monitored input, providing open & short
circuit fault monitoring. The EOL device is a 10 kΩ resistor, giving a AFSLUITER ONJUIST indication. An open
or short circuit fault is indicated by the Blussturing
Storing LED on the display and a Isolation Valve Fault
LED on the motherboard. Three states are possible on
the input:
1 Valve Closed:
Activated by a 680 Ω resistor, flashing the Valve Closed
LED on the display board & pulsing the internal buzzer.
2 Valve Open:
Activated by a 2.2 Ω resistor, no indication is given on
the panel as this is the healthy state for the input.
16
3 Valve Abnormal:
Activated by the 10 kΩ EOL resistor, flashing the
AFSLUITER ONJUIST LED on the display board & raising a general fault indication. A 2-second delay is applied
to the abnormal condition to avoid momentary activation during normal movement of the valve between
open and closed positions.
See Connection Diagram in section 8.3.2 for details.
Note
The healthy state for the input is VALVE
OPEN and therefore, if the input is not used,
the input should have a 2.2 Ω resistor fitted.
Auto/Manual Lock-Off Switch
(AUTO/MANUAL)
The Auto/Manual input is fully monitored for open &
short circuit faults. The End-Of-Line device is a 10kΩ
resistor, activated by a 4.7 Ω resistor. In the active state
the panel is placed in Manual Only mode and the yellow
Handbediening LED on the display board pulses.
Operation of the AUTO & HAND button on the display
board has no effect while the input is active. The input
allows for the connection of Auto/Manual Lock-Off
switches on SLUs. Door Lock switches may also be
connected via terminals on the SLUs. The total number
of Auto/Manual switches & Door Lock switches that
can be connected is 14. This allows for 7 SLUs, each
with an auto/manual Keyswitch and a door lock switch
fitted. See the FIRECLASS Prescient SLU installation
manual for more details.
3.9.4
FIRECLASS Prescient III
3.9.6
Gas Released Pressure Switch
(GAS REL.)
This is a fully monitored input, providing open & short
circuit fault monitoring. The EOL device is a 10 kΩ resistor. An open or short circuit fault is indicated by the
Blussturing Storing LED on the display and a Gas
Released Fault LED on the motherboard. The input
is activated by a 680 Ω resistor, illuminating the Blussing Aktief LED on the display, the Extinguishing
sounder circuit, the Gas Released Signal & all three
shutdown outputs.
3.9.7
Emergency Hold (HOLD)
This is a fully monitored input, providing open & short
circuit fault monitoring. The EOL device is a 10 kΩ resistor. An open or short circuit fault is indicated by the
Blussturing Storing LED on the display and a
Hold Fault LED on the motherboard. If a fault occurs
on the input during the Activated or Discharged condition then the fault indication is still given but the Uitstel Blussing LED is illuminated steady and the Hold
condition is established until the fault is removed. This
fault condition prevents the Extinguishant
release.
The input is activated by a 680 Ω resistor, illuminating
the Uitstel Blussing LED on the display and resetting & holding the pre-discharge delay timer. The 2nd
Stage Relay is also de-energised.
Note
If more than three Emergency Hold switches
connected to the Hold input are operated
simultaneously then a short circuit fault will
be detected. If this occurs while the Pre-discharge timer is running, then the Timer will
still be reset and held until all switches are
released. Use only non-latching switches
which return to open contacts when the
switch is released.
Application, Installation & Commissioning
Doc. version 2
FIRECLASS Prescient III
3.10 Relay Contacts
Note
If an SLU with a Hold switch is configured to
transmit the Hold signal via the serial communications path, a communication fault on this
path will initiate the Hold condition, as
described above, and the release of extinguishant will be inhibited.
3.9.8
Emergency Abort Input (ABORT)
This is a fully monitored input, providing open & short
circuit fault monitoring. The EOL device is a 10 kΩ resistor. An open or short circuit fault is indicated by the
Blussturing Storing LED on the display and an
Abort Fault LED on the motherboard. In addition,
the Blussing Geblokkeerd LED will pulse if the
system is not in the Activated or Discharged condition,
clearing when the fault is cleared. If a fault occurs on the
input during the Activated or Discharged condition then
the fault indication is still given but the Blussing
Geblokkeerd LED is illuminated steady and the Abort
condition is latched until reset. This fault condition prevents the Extinguishant release.
The input is activated by a 680 Ω resistor, illuminating
the Blussing Geblokkeerd LED on the display and
stopping the Extinguishant release. The active abort
condition is latched until the input is cleared and the
Herstel Blussing button is pressed. If the input is
activated during a non-alarm condition then a fault will
be indicated.
Note
Use only LATCHING switches which need to
be manually returned to the OFF position (this
is a requirement of EN 12094-1:2003 clause
4.27.2)
Note
If an SLU with an Abort switch is configured
to transmit the Abort signal via the serial communications path, a communication fault on
this path will initiate the Abort condition, as
described above, and the release of extinguishant will be aborted.
3.10 Relay Contacts
Other than the Auxiliary Reset Relay, all Relay outputs
can be configured as either powered and monitored outputs or Volt-free relay contacts. The factory default is
powered and monitored outputs as required by EN542:1997 & EN12094-1:2003.

Note: Important safety feature
When either zone 1 or zone 2 is placed into
the Test mode, the panel will automatically
set both zone 1 & zone 2 into test mode (see
Table 5). The panel display will show that
BOTH zone 1 & 2 are in the Test mode. The
Test mode for zones 1 & 2 is linked because
the zones are usually used as coincidence
detection zones covering the same area.
Testing detectors on either zone 1 or zone 2
could inadvertently activate detectors on the
other zone.
The clearing of the Test mode is not linked,
i.e. each zone is individually removed from
the TEST mode. This allows the engineer to
test each zone individually if desired (as
required by EN54-2:1997 clause 10.1 (c)).

cleared to the normal mode after power to
the panel is lost.
4.2.2
Configure I.S. Zones
To configure circuits to I.S. operation the required circuit
is selected by moving the Circuit Select Cursor and then
pressing INSCHAKELEN (I.S.) or UITSCHAKELEN
(Normal) as required. The process is as follows:
1 Move the CONFIG I.S. INPUTS DIL switch on
the control board to the ON position. The CONFIG
ON LED on the control board will illuminate, the
buzzer will sound, the SYSTEEM STORING LED will
illuminate and the SELECTEER AAN/UIT LED will
pulse. The fault/disabled LEDs for any circuits
already set to I.S. mode will illuminate.
2 Press the SELECTEER AAN/UIT button. The Select
Cursor will appear on the GROEP 1 fault LED and the
buzzer will silence
3 Press the SELECT button to move the cursor to the
required circuit fault/disabled LED. The cursor will
move in sequence through the relevant circuits and
will then return to the GROEP 1 fault LED.
4 Press the INSCHAKELEN or UITSCHAKELEN button
as required (to ENABLE I.S. or DISABLE I.S.).
5 Repeat steps 3 & 4 for any additional circuits.
6 Press SELECTEER AAN/UIT to switch off the cursor (the cursor is automatically switched off if no buttons are pressed for 60 seconds).
7 Move the CONFIG I.S. INPUTS DIL switch on
the control board to the OFF position.
Note
The I.S. configuration status is stored in
EEPROM and is not lost when power to the
panel is lost.

FIRECLASS Prescient III
WARNING
The use of capacitors on intrinsically
safe zones is dangerous and carries a
risk of explosion. I.S. zones require a
3.9 kΩ EOL resistor.
4.2.3
Configure SLU (Status Lamp
Units)
If SLUs are used with the panel, the panel needs to
know the type of SLU connected and the address of the
SLU. The configuration process is as follows:
1 Move the CONFIG SLU DIL switch on the control
board to the ON position. The CONFIG ON LED on
the control board will illuminate, the buzzer will
sound, the SYSTEEM STORING LED will illuminate
and the SELECTEER AAN/UIT LED will pulse. The
two-digit display for BLUSVERTRAGING will show
SLU address 1 for the first digit and the type code of
that SLU on the second digit:
– 10 = SLU address 1, set to Type code 0 (no SLU
with address 1)
– 11 = SLU address 1, set to Type code 1
– 12 = SLU address 1, set to Type code 2
– 13 = SLU address 1, set to Type code 3
– 14 = SLU address 1, set to Type code 4
Note
If a SLU is configured to use the panel circuits
for switch monitoring, the SLU will automatically be configured as an indication only unit.
The panel must therefore be configured for a
type 1 SLU at the corresponding address.
2 Press the SELECTEER AAN/UIT button. The first
digit will pulse (SLU address) and the buzzer will
silence, indicating that the SLU edit mode is active.
3 Press the SELECT button to change the SLU
address value. The second digit will show the Type
code set for the selected address. The SLU address
digit will change in sequence: 1 2 3 4 5 6 7
and then back to 1.
4 When the first digit displays the address of the SLU
to be configured, press the INSCHAKELEN button.
The SLU address digit will go steady and the Type
Code digit will flash.
5 Press the SELECT button to change the Type Code
to the desired value, valid values: 0 1 2 3 4. The
configuration is stored immediately in EEPROM.
6 Press INSCHAKELEN to switch between flashing
the first & second digits (address change or type
code change).

CAUTION: Battery Connection
Connecting only one 12 volt battery or
incorrect connection of the batteries will
permanently damage the panel and the
battery.
The battery charger circuit is temperature compensated
and relies on a Thermistor mounted near the batteries
to ensure that the correct charging voltage is maintained. The Thermistor type has been chosen to fit the
profile of the Powersonic VRLA batteries. Use of batteries by another manufacturer is not recommended.
WARNING: Fuse Replacement
A fuse protects the internal power
supply; always replace this with the
correct type and rating:
 T5AH250V
(20 mm fuse, 5 A, HBC, Anti-surge,
approved to BS EN 60127 or

5.2 Standby Battery Requirements
FIRECLASS Prescient III
5.2
Standby Battery Requirements
5.2.1
Battery Capacity Calculation
The usual requirement for standby batteries is 24 Hours
standby, plus 30 Minutes in Alarm.
Use the following as a guideline when calculating your
requirements.
24 Hours Standby
Mains Failed
Current
(A)
X Standby 
Time

Capacity
Required
(Ah)
Mains Failed current is 0.060 A plus ancillary equipment
e.g. if a Status Indicator draws 0.030 A then the total
Mains Failed current is 0.090 A.
Therefore over 24 hours the battery requirement is:
0.090 X 24 = 2.16 Ah

Battery Capacity
Note that the enclosure will only accommodate two 12 V batteries up to 12 Ah capacity.
Larger sized batteries fitted in a separate
enclosure are not permitted.
5.2.2
Battery Replacement
The useful life of the standby batteries in this panel is
three years. The batteries must be replaced after this
time. To ensure this, when first installed, the battery
should be clearly labelled with the date of installation
and scheduled replacement date.
5.2.3
Battery Charging
The battery charger voltage is set during manufacturing
and should not require adjustment. The output voltage
can be verified by measuring the voltage across the battery terminals on the internal control board with the batteries connected. The battery charger output should be
27.10 V +/- 0.05 V @ 25 oC (Thermistor value 15 k.)
If the charger voltage requires adjustment, use an insulated trimming tool to adjust the potentiometer SVR1 on
the Power Supply (see PSU layout diagram in Fig. 6 for
location). See Table 7 for recommended charge voltages.
Alarm current is 0.160 A plus the detector current plus
alarm and solenoid current plus ancillary equipment e.g.
if one detector is in alarm and draws 0.030 A, and the
alarm load is 1.0 A, and the actuator load is 1.0 A and a
Status Indicator draws 0.040 A then the total Alarm current is 2.23 A.
Therefore over 30 Minutes the battery requirement is:
(2.23 X 0.5) x 1.5 = 1.67 Ah.
Therefore the total Battery requirement is:
2.16 Ah + 1.67Ah = 3.83 Ah
Use batteries with a rating of at least 25% more than
the capacity required. This is to allow for deterioration of
the batteries during use. So the minimum battery capacity required in this example is:
1.25 x 3.83 = 4.79 Ah

Notes
The following points are to be noted:
 Detector quantities are based on the use of
a 22 uF capacitor as the end-of-line device,
except for intrinsically safe devices, in
which case the EOL is a 10 kΩ resistor.
 If the DIL switch option ‘3.9 kΩ EOL’ is
selected, then the maximum number of
detectors per zone will be reduced. In this
case the maximum detector current in
standby should not exceed 2.3 mA. As a
general rule the quantities shown above
should be halved.
 Detector models not listed above may be
compatible if electrically similar to the
above devices. Consult your supplier for
advice.
 All break glass units (call points) must have
a resistor fitted to them to produce an
alarm condition on the panel. Any value
between 100 Ohm and 680 Ohm is
acceptable. Please check with your supplier if you are not sure.
 It is not permitted to connect more than 32
detectors to any zone. (The Manual
Release circuit is not a detection zone and
therefore should only have MCPs fitted).

6 Panel Installation & Commissioning
Panel Installation & Commissioning
The control panel must be installed by suitably qualified
technicians familiar with the installation of fire detection
& extinguishing systems. In addition, it is recommended to refer to the following information:
1 Current edition of the IEE wiring regulations.
2 Current edition of BS5839-1 or the installation standards for the relevant country.
3 Any site-specific requirements.
4 Any field device installation instructions.
5 Any data sheet provided for the installation of Intrinsically Safe devices.
WARNING: Installation Compliance
Read this section completely before
commencing installation.
Prior to commencing installation of the control panel,
ensure that adequate precautions are taken to prevent
damage to the sensitive electronic components on the
control board due to electrostatic discharge. You should
discharge any static electricity you may have accumulated by touching a convenient earthed object such as
an unpainted copper radiator pipe. You should repeat
the process at regular intervals during the installation
process, especially if you are required to walk over carpets.
The panel must be located in a clean, dry position, which
is not subject to shock or vibration and at least 2 metres
away from pager systems or any other radio transmitting equipment. The operating temperature range is 5 ºC to +40 ºC; maximum humidity is 95%.
IMPORTANT SAFETY CONSIDERATIONS FOR
BATTERIES:
DANGER: Battery Terminals
Batteries are electrically live at all
times, take great care never to short
circuit the battery terminals.
Application, Installation & Commissioning
Doc. version 2
WARNING: Lifting Battery
Batteries are often heavy; take great
care when lifting and transporting
batteries. For weights above 24 kilos,
lifting aids should be used.
DANGER: Do NOT Tamper with
Battery
Do NOT attempt to remove the
battery lid or tamper with the internal
workings of the battery. Electrolyte is
a highly corrosive substance, and
presents significant danger to
yourself and to anything else it
touches. In case of accidental skin or
eye contact, flush the affected area
with plenty of clean, fresh water and
seek immediate medical attention.
Valve Regulated Lead Acid (VRLA)
Batteries
Valve Regulated Lead Acid (VRLA) batteries
are “low maintenance”, requiring no electrolyte top-up or measurement of specific
gravity.
WARNING: Battery Cleaning
 Only clean the battery case with a
cloth that has been soaked or
dampened with distilled water.
 Do not use organic solvents (such
as petrol, paint thinner, benzene or
mineral spirits) or other materials
that can substantially weaken the
case.
 Do not use a dry cloth as this will
generate static electricity, which in
turn may lead to an explosion.
43
6.1 Cable Recommendations
WARNING: Battery Operating
Temperature
Avoid operating temperatures
outside the range of -15 °C / 5 °F to
+50 °C / 122 °F for float/standby
applications.
 The recommended normal operating temperature is 20 °C.
 HIGH TEMPERATURE will reduce
battery service life. In extreme
cases this can cause Thermal Runaway, resulting in high oxygen/
hydrogen gas production and battery swelling. Batteries are irrecoverable from this condition and
should be replaced.
 LOW TEMPERATURE will prolong
battery life but reduce output
capacity.
DANGER: Do NOT Incinerate Batteries
 Do not incinerate batteries. If
placed in a fire, the batteries may
rupture, with the potential to
release hazardous gases and electrolyte. VRLA batteries contain substances harmful to the environment.
 Exhausted batteries must be recycled. Return them to the battery
manufacturer or take them to your
Council waste disposal site for
appropriate disposal.
ELECTRICAL SAFETY:
The volt-free relay contacts provided within the panel
must not be used to directly switch any voltage that
exceeds 50 V AC or 75 V DC. (Please also refer to relay
rating data).
This equipment requires a 230 V AC supply. All installation work should be carried out in accordance with the
recommendations of BS5839 Part 1 and the current edition of the IEE regulations by suitably qualified and
trained personnel.
DANGER: THIS PANEL MUST BE
EARTHED
All electrically conductive parts of
this installation must be bonded to
the protective earth for safety.

Commissioning Procedure
In order to avoid accidental operation of the solenoid
valves during commissioning the solenoid valves should
remain disconnected during the commissioning process. A suitable load resistor (typically 47 Ω, 20 W, providing a 0.6 A load, check manufacturer’s datasheet for
actual current or coil resistance) should be connected in
place of the solenoid to simulate the presence of the
solenoid coils. The solenoid coils should be connected
only at the end of the commissioning process.
The commissioning engineer should also be aware of
any additional equipment connected to the panel and
the consequences of the operation of that equipment
during the commissioning process.
Make sure that the BEDIENING Keyswitch is in the AAN
position before operating any of the buttons on the display board.

The Panel can now be configured for the specific
requirements of the site via the internal DIL switches.
Once configured, the panel functions should be tested
to ensure correct configuration.
For any optional circuits in use (i.e. GAS LOW, ISOL.
VALVE, GAS TRAPPED, HOLD, ABORT, REMOTE CTRLS,
AUTO/MANUAL, 1st, 2nd & 3rd Stage Shutdowns)
these should also be checked for open & short circuit
faults, and for correct activation.
If Status Indicators are used then check that the correct
indications are shown on the status indicators and any
switches fitted operate correctly.
NOTICE: Actions Required After
Commissioning Procedure
 Once all Panel functions have been fully
tested, the panel should be set to the
AUTOMATIC & MANUAL mode and left on
soak for 24 hours. DO NOT CONNECT THE
SOLENOID VALVES DURING THIS
PERIOD.
 After the panel has been successfully
soak-tested, the SOLENOID VALVES may
be connected to the actuator circuits and
the panel can be locked and left in a fully
operational state. Do not arm the
extinguishing system without authorization from the Site’s designated Responsible Person.
 All authorised users must be given adequate instruction/training on the operation
of the extinguishing system prior to handover.

System Maintenance
7.1
Overview
1 The Fire detectors & Sounders should be tested
weekly and a note made in the system logbook.
2 The operation of manual call points and detectors
should be carried out on a rotational basis so that all
devices are checked at least once over a 3-month
period.
CAUTION: Disable Extinguishing
System
Ensure that the extinguishing system is
physically disabled by electrical or mechanical
disconnection before carrying out any tests.
3 To operate a manual call point, use the Test key provided.
4 To operate a detector, use an approved Test Smoke.
5 Check the operation of auxiliary items such as door
closers.
6 Re-enable any disabled circuits after completing the tests.
7.2
Weekly Test Routine
1 Operate one manual call point and one detector.
These should be on separate zones and the zones
should be varied each week (unless all zones are
always tested).
2 Check that sounder circuits 1 & 2 operate.
3 Remove the test key from all manual call points and
clear all detectors of smoke.
Application, Installation & Commissioning
Doc. version 2
4 Press the HERSTEL BRANDALARM button.
5 Operate the test lamps switch and observe that all
indications operate for 5 seconds and the buzzer
sounds.
6 Test one hold, one abort and one auto/manual
switch (if fitted). These should be on separate SLUs
and should be varied each week.
7 Check that operation of the hold switch indicates a
hold condition on the SLU.
8 Check that operation of the abort switch indicates an
abort condition on the SLU.
9 Check that operation of the auto/manual switch
changes the panel from automatic & manual to manual only operation, as indicated at the SLU.
10 Operate test lamps on each SLU and observe that all
indicators operate.
11 Enter details of the weekly test in the log book.
CAUTION: Deactivate Disable
