3.1 Accessing the User Interface
The VAR8-ACU is password protected in order to prevent unauthorised alteration of the system configuration. Thus the system configuration cannot be changed unless the operator is ‘Logged on’ by entering the correct Access Code.
When the operator is 'Logged off' it is not possible to change any configurable items, or to clear any fault logs. It is, however, possible to view all the system information apart from the access code.
The factory default access code is ‘0999’.
!
!
Only qualified personnel who are very familiar with the VAR8-ACU equipment, the installation and its configuration requirements should ‘Log-on’ to alter the system configuration.
Any adjustment of audio parameters or DVA zoning may leave the system in a dangerous state where it will not correctly respond to alarm inputs or may not produce adequate sound pressure levels or intelligibility to comply with Voice Alarm Standards.
Similarly it is possible for the untrained operator to inadvertently disable system surveillance functions, which are mandated by Voice Alarm Standards.
3.2 Navigating the Menus
Figure 2 Example of Display (Top-level Menu)
LCD Display Line 1
Displays the menu description and whether the user is logged on or logged off.
On the top-level display the system type, and the current date and time are shown. If a fault occurs, then the unit displays text describing the fault. This fault text is alternated with a display of the current date and time.
In the event of multiple faults each fault is displayed in sequence, while alternating with the date and time display.
LCD Display Line 2
Displays menu options.
3.2.1 Menu Selection Markers
Different markers are used to aid menu navigation as follows:
• [square brackets] indicate this option is an editable field or can be scrolled using the up and down arrows.
• {curly braces} indicate this option is read-only, for instance if the user is logged off.
• !arrows both sides" indicate this option leads to a sub-menu.
• !arrow on left, bracket on right] indicates this option can be scrolled using the up and down arrows and when selected will lead to a sub-menu for the selection.

3.2.2 Selecting Menu Item and Saving Changes
Use the
W
and
X
keys to move to the next item in the menu.
To select a [highlighted] item press the SELECT key. To save changes, press the SELECT key.
To exit from the current menu and to return to the parent menu without saving changes, press the BACK key.
3.2.3 Changing Option
Use the
S
and
T
keys and the rotary encoder to edit or scroll options.
The rotary encoder has multiple functions dependent on the current menu selection as follows:
• Fast increment and decrement of menu items (faster than using
S
and
T
arrow keys)
• Acts as a Volume Control during Audio Monitoring.
3.3 LCD Display Timeouts
All menus timeout to revert to the previous (higher) level after two minutes with no user activity. If logged on, then after five minutes with no activity the user is logged off. Thus with no user activity the LCD display always returns to the top-level display and logged off state.
The LCD backlight is under control of the processor. It is switched on whenever any button is pressed, and stays on for five minutes after the last key press has occurred. Should a fault occur, the backlight is automatically illuminated.

6 Network Operation Setup
L Any network fault causes the Audio Control Unit to operate in All Call mode.
A Slave Unit operating in All Call mode due to a processor fault results in a network fault, thus causing the Audio Control Unit to operate in All Call mode.
The Intellevac Network’s 8x8 Audio Control Unit supports the following Slave Units:
• Wall mount Intellevac Distributed Amplifier Units, both legacy 4x4 DAUs and 8x8 DAUs.
• Rack mount VAR12 and VAR20 Routers, using the VAR Network Interface Adapter (VAR-NIA).
• Rack mount VAR8 Routers fitted with ANIC Network Interface Card.
The Audio Control Unit normally ‘talks’ out of its UPSTREAM port, which is connected to the
DOWNSTREAM port of the first Slave Unit in the chain. The UPSTREAM port of that Slave Unit is then connected to the DOWNSTREAM port of the following system until a complete ‘ring’ is implemented back to the Audio Control Unit.
The first Slave Unit is allocated a Slave-ID of 1, the next unit has Slave-ID 2 etc. The Slave-ID corresponds to the Slave Unit’s physical position in the network.
Figure 3 shows the scheme of an Intellevac Network hosted by an 8x8 Audio Control Unit in which the
different types of Slaves Units are interconnected.
• Number of Slave Units: up to 30 units (120 network zones)
• Maximum distance between nodes: 1 km
• Network Control Response Time (Fire Alarm trigger to DVA initiation): <1 second
6.1.2 Main Network Features
• Slave Units can be any combination of: Intellevac 4x4 DAUs; Intellevac 8x8 DAUs; VAR8 Routers fitted with an ANIC Network Interface Card; and VAR12/20 Routers using a VAR-NIA interface unit.
• Slave-IDs must correspond to the Slave Unit’s physical position in the network.
• Not all Slave Unit Outputs have to be Network Outputs.
−
−
On legacy 4x4 DAUs, all outputs need to be Network Outputs.
• Network Outputs do not have to be numbered in the same order as the Slave Ids and Slave Outputs, nor do they have to be contiguous (i.e. there can be gaps).
On legacy 4x4 DAUs, Network Outputs are numbered based on its Slave Id and they do need to be contiguous.

7.2 Input Emergency Class Configuration
The emergency class is used by Fire Microphones connected to the VAR8-ACU to indicate the emergency
DVA message status of the zone or group of zones configured for a zone select button via its red and green
LEDs. Refer to Section “ 8.2 DVA Input Emergency Class Configuration ” for further details.
L From ACU V1.5.0114 or later, it is possible to configure a microphone connected to a
VAR8-ACU between this mode and the standard mode. In the standard mode the Emergency
Class does not affect the behaviour of the LEDs with the red LED turning ON continuously to indicate that the zone (either one or more of the group of zones controlled by this button) is already in use by another input, and the green LED indicating the zone selection state. See step
6 in Section “ 7.3 Microphone Parameters Configuration ” for further details.
To Modify the Emergency Class:
4. Access the following menu, and then modify the Mic/Line input emergency class as required.
Menu: ConfigurationÆSystemÆRouterÆInputsÆMic/LineÆI/P #<nn>Æ<mic type>ÆCtrlÆClass
L As standard Mic/Line input class is set to ‘Non Emergency’. This setting should remain unchanged as it may result in an inappropriate indication of the emergency message status on the Fire Microphones connected to the VAR8-ACU, as described in Section
“ 8.2 DVA Input Emergency Class Configuration ”.

6. Select the behaviour of the red and green LEDs of zone select buttons on Fire Microphones connected to the VAR8-ACU.
Menu: ConfigurationÆSystemÆRouterÆInputsÆMic/LineÆI/P #<nn>Æ<mic type>ÆCtrlÆLEDs
• ‘Busy Class’ mode:
The red and green LEDs indicate the emergency message status of the zone group configured for a zone select button according to the emergency class, which is typically set-up as follows:
− EVACUATE DVA: High Priority Emergency
− ALERT DVA: Low Priority Emergency
− Other audio sources (microphone, auxiliary DVAs, music): Non Emergency
The red and green LEDs are driven as follows:
− The red LED is turned ON continuously if any output in the group configured for the button is connected to an input that has been configured as a High Priority Emergency source.
The green LED is turned ON continuously.
− The red LED flashes ON and OFF repeatedly if any output in the group configured for the button is connected to an input that has been configured as a Low Priority Emergency source, and no output in the group is connected to a High Priority Emergency source.
The green LED is turned ON continuously.
− The red LED is turned OFF if any output in the group configured for the button is connected to an input that has been configured as a Non Emergency Priority source, and no output in the group is connected to a High or Low Priority Emergency source.
The green LED is turned ON continuously.
− The red LED is turned OFF if all outputs in the group configured for the button are not connected to any input.
The green LED is turned OFF.
This is the default setting for Fire Microphones.
Refer to Section “ 8.2 DVA Input Emergency Class Configuration ” for further details.
• ‘Busy Standard’ mode:
The red LED is turned ON continuously to indicate that the zone (either one or more of the group of zones controlled by this button) is already in use by another input, and the green LED indicates the zone selection state. The input emergency class has no effect on the LED indication.
This is the default setting for Paging and Single Button Microphones.

L • The input gain of each audio input should normally be set so that all inputs are balanced and give the same output level on each of the outputs.
• The default setting for an ASL microphone is –14dB. With ASL microphones any further volume adjustments should be made using the output specific relative gains, as described in next step.
11. Select whether or not the router detects and reports loss of a low-frequency (LF) surveillance tone. The detection threshold level is also adjustable.

For BS5839 compliance the input surveillance MUST be enabled on Fire Microphone.
L • ASL Microphones produce this surveillance tone as standard and typically this feature would be enabled (set to ‘LF’) if any ASL proprietary microphone is used, in order to provide monitoring of the audio cabling.
• The surveillance tone level adjustment is described in the following guideline. Note that after each setting the SELECT key should be pressed to save the new configuration.
• When the Router input is connected to an audio source other than an ASL microphone, this feature should be disabled (set to ‘Off’) in order to prevent faults from being raised, e.g., background music, PC/DVA system, non-ASL microphones, etc.

VAR8-ACU and Variants - Operation, Commissioning, Fault Finding, and Maintenance Guide
To Adjust the Surveillance Tone Level on ASL Microphones: a. Set ‘Mode=LF’ and ‘Level (dB)=–40’. b. Clear any existing faults by pressing the FAULT CLEAR button on the system front panel. c. Any fault reported by the microphone at this stage should be cleared. d. Raise the surveillance tone level slowly (1dB step) from –40dB until the “IPXX AUDIO INPUT” fault is reported. Where XX is the Mic/Line input to which the microphone is connected. e. Set the surveillance tone level to 4dB below the level that caused the fault to be reported.
E.g. if a –18dB level causes the fault, then set the surveillance tone level to –22dB. f. Make sure that no fault is reported for the microphone.
12. Define the relative gain for each frequency band (low, mid, and high frequencies) of the 3-band equaliser.
A switchable High Pass filter is also configurable. This would typically be used on microphone inputs to prevent excessive ‘pop’ noise.

13. Define the time over which this audio channel is faded up/down when audio sources change.
Menu: ConfigurationÆSystemÆRouterÆInputsÆMic/LineÆI/P #<nn>Æ<mic type>ÆAudioÆFade
L • The time is given in tenths of a second, so divide by ten for the time in seconds.
• It is important for Fire Microphones to be able to override other sources quickly; therefore Fire Microphones are set-up for a short Fade Down time.
The Fade Down time is:
• The time it takes for the signal to fade down when turned off (un-routed);
• The time it takes for the signal to fade down before an overriding broadcast is made in its place
The Fade Up time is the time the signal takes to fade up when:
• Turned on (routed);
• Override removed.
This can be set to provide the desired changeover fading, e.g. when a broadcast interrupts background music, or a lower priority broadcast.
This is typically used on background music where a slow fade-up, in particular, is desirable.

L • 19 priority levels are assignable to any of the audio input sources.
• Assignment of equal priorities means that those inputs operate on a ‘first-come-first-served’ basis.
• The lower the priority value, the higher the priority.
The input priority is used to resolve conflicts on the allocation of the network channels when two or more inputs try to broadcast. In this case the inputs with the highest priorities will be able to broadcast over the configured network channels, and the others will not.
Priority is assignable to each input. This is so that the assignment of the network channels can be arbitrated between the audio inputs into the Audio Control Unit.
To Allocate Priority to a Mic/Line Input:
15. Select the input, and then modify its priority as required.
Menu: ConfigurationÆSystemÆRouterÆInputsÆMic/LineÆI/P #<nn>Æ<mic type>ÆCtrlÆPri
Possible options: 01 to 19 (01 is the highest priority)
!
!
Care should be taken in ensuring that Fire Microphones, and Alarm and Emergency DVAs have a high priority and non-emergency sources, such as non-emergency DVAs, Paging
Microphones, and music sources, have low priorities. This is to ensure that these emergency inputs can override normal inputs.

The VAR4, VAR12, and VAR20 Routers are capable to provide a mixed ‘listen-in’ output.
A specially assigned button or key-switch may be configured for controlling the 'listen-in' function on microphones provided with ‘listen-in’ button or key switch. One example of this is the ‘listen-in’ button on the
ASL Station Master Console (SMC) microphones.
The ‘listen-in’ button or key-switch may be operated in the following modes:
• 'Listen-to-All'
For each VAR Router in the network, all network outputs will be mixed together and routed the VAR
Router’s Aux Output.
The Aux Output from each Slave VAR Router can be mixed with those of the other Slave Units by OEM hardware, with the resultant “super-mix” fed to a suitable central loudspeaker, typically the SMC loudspeaker.
The 'Listen-to-All' mode is activated by activating the ‘listen-in’ button or key-switch momentarily. Reactivating the ‘listen-in’ button or key-switch momentarily will deactivate the ‘listen-in’ function.
When the 'Listen-to-All' is active, the normal paging operation will be allowed, and the ‘listen-in’ mode automatically deactivated.
Each time the button or key-switch is momentarily activated this toggles the ‘listen-in’ mode between inactive and active. When toggling ‘listen-in’ from inactive to active clears previous zone selection.
The ‘listen-in’ LED on the microphone console will be lit while the ‘listen-in’ function is activated.
• ‘Selective Listen-in’
For each VAR Router in the network, the audio associated with a selected zone or zones will be mixed together and routed the VAR Router’s Aux Output.
The Aux Output from each Slave VAR Router can be mixed with those of the other Slave Units by OEM hardware, with the resultant “super-mix” fed to a suitable central loudspeaker, typically the SMC loudspeaker.
The ‘Selective Listen-in’ mode is activated by selecting zone select buttons while the ‘listen-in’ button or key-switch is held in active state. It is possible to add other sources to the audio-mix by momentarily pressing the associated zone select buttons. Re-activating the ‘listen-in’ button or key-switch momentarily will toggle to inactive mode and clear any zone selection.
When the ‘Selective Listen-in’ is active, the normal paging operation will be barred.
Each time the button or key-switch is momentarily activated this toggles the ‘listen-in’ mode between inactive and active. When toggling ‘listen-in’ from inactive to active clears previous zone selection.
The ‘listen-in’ LED on the microphone console will be lit while the ‘listen-in’ function is activated.

8.2 DVA Input Emergency Class Configuration
The Emergency Class is only relevant in networked units, and is used by Fire Microphones connected to the
VAR8-ACU to indicate the emergency DVA message status of the zone group configured for a zone select button via its red and green LEDs, as described in
Table 6 . This is achieved by setting the appropriate
Emergency Class to each of the VAR Router inputs, as described in the following procedure.

N o EVACUTE and no ALERT messages are playing to any output in the zone group controlled by this button.
L From ACU V1.5.0114 or later, it is possible to configure a microphone connected to an ACU between this mode and the standard mode. In the standard mode the Emergency Class does not affect the behaviour of the LEDs with the red LED turning ON continuously to indicate that the zone (either one or more of the group of zones controlled by this button) is already in use by another input, and the green LED indicating the zone selection state. See Section “
Microphone Parameters Configuration ” (page 29 , step 6 ) for further details.
To Modify the Emergency Class of a DVA Input:

In order to provide the emergency DVA message status indication described in
EVACUTE DVA should be set to ‘High Priority Emergency’, the ALERT DVA should be set to ‘Low Priority Emergency’, and the remaining audio sources should be set to
‘Non Emergency’ as specified in the system default settings.
The system default setting is:
• DVA Input 1 (DVA1) - EVACUATE: High Priority Emergency
• DVA Input 2 (DVA2) - ALERT: Low Priority Emergency
• DVA Inputs 3 and 4 (DVA3 and DVA4): Non Emergency
• Mic/Line Inputs: Non Emergency

4. Select the DVA input, and then modify the required audio parameters as follows.
5. Define a gain to be applied to the DVA input, in respect of any output to which it may be routed.
Menu: ConfigurationÆSystemÆRouterÆInputsÆDVAÆDVA #<n>ÆGainÆInput
L The input gain of each audio input should normally be set so that all inputs are balanced, and give the same output level on each of the outputs.
L • 19 priority levels are assignable to any of the DVA inputs.
• Assignment of equal priorities means that those inputs operate on a ‘first-come-first-served’ basis.
• The lower the priority value, the higher the priority.
The DVA priority is used to resolve conflicts on the allocation of the network channels when two or more inputs try to broadcast. In this case the inputs with the highest priorities will be able to broadcast over the configured network channels, and the others will not.
Priority is assignable to each DVA. This is so that the assignment of the network channels can be arbitrated between the audio inputs into the Audio Control Unit.
To Allocate Priority to a DVA Input:
6. Select the DVA input, and then modify its priority as required.
Menu: ConfigurationÆSystemÆRouterÆInputsÆDVAÆDVA #<n>ÆPri

Care should be taken in ensuring that Fire Microphones, and Alarm and Emergency DVAs have a high priority and non-emergency sources, such as non-emergency DVAs, Paging
Microphones, and music sources, have low priorities. This is to ensure that these emergency inputs can override normal inputs.

7. Define the time over which this audio channel is faded up/down when audio sources change.
Menu: ConfigurationÆSystemÆRouterÆInputsÆMic/LineÆI/P #<nn>ÆAudioÆFade
L • A slow fade up time is desirable for music inputs.
• The time is given in tenths of a second, so divide by ten for the time in seconds.
• It is important for Fire Microphones to be able to override other sources quickly; therefore Fire Microphones are set-up for a short Fade Down time.
The Fade Down time is:
• The time it takes for the signal to fade down when turned off (un-routed);
• The time it takes for the signal to fade down before an overriding broadcast is made in its place
The Fade Up time is the time the signal takes to fade up when:
• Turned on (routed);
• Override removed.
This can be set to provide the desired changeover fading, e.g. when a broadcast interrupts background music, or a lower priority broadcast.

L • 19 priority levels are assignable to the Music input.
• Assignment of equal priorities means that those inputs operate on a ‘first-come-first-served’ basis.
• The lower the priority value, the higher the priority.
• DAU:
The input priority is used to resolve conflicts when two or more inputs try to broadcast to the same output. In this case the input with the highest priority will be able to broadcast, and the others will not.
Priority is assignable to each input per output. This is so that different inputs may have different priorities according to which zone they are serving. For example a particular microphone may have a high priority only in its local zone, and a lower priority when broadcasting elsewhere.
When Music input is overridden, then when the override is removed it is re-instated.

14 DVA or Route Triggers via Contact Configuration
Any Router contact or Remote I/O Unit digital input may be configured to trigger a route connecting any desired combination of audio inputs to any combination of outputs. Audio inputs are typically DVAs, however other type of inputs such as microphone, background music, and test tone can also be routed.
Therefore a single contact may cause an EVACUATE message to be broadcast in one zone, and simultaneously cause an ALERT message to be broadcast to some other zones while all remaining zones are unaffected.
It is possible to configure how the route will be triggered:
• Not Latched mode
The activation of a contact configure for Not Latched mode initiates a route. When the contact is released, the route is cleared.
This mode is suitable for routing any type of input.
• Latched mode
A momentary, or prolonged, activation of a contact configured for Latched mode initiates a route.
A separate contact must be specified to act as a reset contact whose activation clears the route unless the corresponding trigger is still asserted.
This mode is suitable for routing any type of input.
The DVA assigned to a button may be configured to cease playing when the route is terminated or reset
(DVA-Part), or play until its end (DVA-Full).
It is also possible to configure whether or not the route associated with a contact should cause a busy indication on the LEDs associated with microphone zone select buttons. If for instance this routing were used for background music control, then the busy LEDs would not be lit. If another type of route were being made, then the busy LEDs would normally be lit.
L The Remote I/O Unit needs to be programmed prior to configuring its inputs and outputs, see
Section “
13 Remote I/O Unit Configuration ”.

This mode is useful for the control of both DVA routes and other sources, such as background music.
This is the system default setting.
• Latched:
A momentary, or prolonged, activation of a ‘Routing’ contact configured for Latched mode initiates a route; and activating the associated reset contact terminates it unless the corresponding trigger is still asserted.
This mode is normally used for emergency DVA message routes, but can also be of use for routing other inputs.
Issue: 02 complete, approved
Page 70 of 138
VAR8-ACU and Variants - Operation, Commissioning, Fault Finding, and Maintenance Guide
This method is used normally to trigger emergency DVAs although any input source may be routed in this way. For Fire Alarm DVA messages, BS5839 Pt.8 recommends the use of latched triggers with separate resets so that the message will continue to run even if the trigger pair fails.
Each latching trigger is configurable to initiate routing of any DVA to any output. It is possible to initiate simultaneous routing of multiple DVAs to multiple Outputs. This is so that, for example,
ALERT and EVACUATE messages may be broadcast to different zones by a single trigger. The
DVA(s) will play until a momentary assertion of the matching reset contact, unless the corresponding trigger is still asserted, in which case the DVA will not be reset.
A group of route triggers may share a single reset, or each route trigger has its own dedicated reset.
If multiple DVA routes have been triggered by consecutive triggers in a single group, the activation of that group’s reset contact unlatches all the DVA routes associated with that reset. However, if any of the triggers are still asserted, these DVA(s) routes continue to play while the others will be reset.
A group of route triggers may share a single reset, or each route trigger has its own dedicated reset.

Each latching trigger is configurable to initiate routing of any DVA to any output. It is possible to initiate simultaneous routing of multiple DVAs to multiple Outputs. This is so that, for example,
ALERT and EVACUATE messages may be broadcast to different zones by a single trigger. The
DVA(s) will play until a momentary assertion of the matching reset contact, unless the corresponding trigger is still asserted, in which case the DVA will not be reset.
A group of route triggers may share a single reset, or each route trigger has its own dedicated reset.
If multiple DVA routes have been triggered by consecutive triggers in a single group, the activation of that group’s reset contact unlatches all the DVA routes associated with that reset. However, if any of the triggers are still asserted, these DVA(s) routes continue to play while the others will be reset.

19 Establishing and Testing Network Connection
The easiest method is to introduce units onto the network one at a time.
To do this:
1. Set the Network to UPSTREAM ONLY initially via Audio Control Unit front panel menu
ConfigurationÆSystemÆNetworkÆDiagnosticsÆTx-DirÆInputs.
2. Set Audio Loop Recovery to SUPPRESSED via Audio Control Unit front panel menu
ConfigurationÆSystemÆRouterÆMiscÆAudio recovery.
3. See Section “
20 Network Faults – Recovery and Diagnosis ”.
4. The Audio Control Unit will then be configured for one Slave Unit and a basic test carried out to ensure that there are no communication faults or audio faults on the Slave Unit.
5. The next Slave Unit should then be configured at the Audio Control Unit and communications to each checked, until the whole system is operating. The Network should be set to BI-DIRECTIONAL and Audio
Loop Recovery ENABLED so the system is then operating as a loop.
6. To check whether the network is operating correctly at each stage, it is important to CLEAR all Slave faults from the Audio Control Unit and the CLEAR the Audio Control Unit’s own faults.
7. See Section “
21 Diagnostic Tools and Methods ” for methodology for diagnosing network faults.
L The ACU provides a diagnostics tool to enable normal paging when the ACU goes into All
Call mode. This tool may be used during installation and commissioning when the Slave
Units may not be functional causing the ACU to operate in All Call mode.
Suppress the All Call mode to DISABLED via Audio Control Unit front panel menu
ConfigurationÆSystemÆNetworkÆMiscÆAll-call. The All Call mode is automatically
ENABLED when the user logs off, alternatively the user can set the All Call mode back to

20 Network Faults – Recovery and Diagnosis
Operation
The diagram below shows network operation in a fault free condition. All data originated from the
Audio Control Unit is transmitted from the
UPSTREAM port to the DOWNSTREAM port of the first Slave Unit. The data is then copied through each Slave Unit until it is received back at the Audio Control Unit. Each Slave Unit replies in the direction from which it receives data.
20.2 Data Network Operation with Fault
If an open or short circuit failure occurs, such that the Audio Control Unit fails to see its own transmissions coming back, it starts to transmit in both directions, UPSTREAM and
DOWNSTREAM. This prevents an interruption in the ring from interfering with the network data communication. This is shown in the diagram below.

The audio passes though each Slave Unit, unbuffered. Each Slave Unit merely tapping off the audio.

Operation with Fault
The audio bus has a 30Hz surveillance signal superimposed on the normal VA audio. This surveillance tone is monitored at each Slave
Unit, and enables the Slave Units to report fault in the network.
Because the audio bus is un-buffered at each
Slave Unit, a short circuit will cause complete failure of the ring, and cause all Slave Units to report failures. An open circuit will cause only
Slaves downstream of the fault to report faults.
As soon as any audio faults are reported the system goes into fault recovery sequence, which, in essence, isolates the Slave Units at each side of a potential cable fault until the fault is pinpointed. Once this is done the faulty segment remains isolated and the audio from the Audio Control Unit is transmitted in both
UPSTREAM and DOWNSTREAM directions to the slaves. This is shown in the diagram below. UPSTREAM

21 Diagnostic Tools and Methods
The system has various useful diagnostic features to enable the location of a fault to be pin-pointed during commissioning and for maintenance purposes.
21.1.1 Hardware
The Network Interface Card has a series of diagnostic LEDs. Their functions are annotated on the cover plate silkscreen.
DOWNSTREAM UPSTREAM
The following indicators are available for both UPSTREAM and DOWNSTREAM ports.
LED Function
ACTIVITY
BUS1-FAULT
BUS2-FAULT
BUS3-FAULT
Indicates any data activity on the RS485 port, transmission or reception
Illuminates if the Slave has isolated audio bus-1 because of a fault
Illuminates if the Slave has isolated audio bus-2 because of a fault
Illuminates if the Slave has isolated audio bus-3 because of a fault
21.1.2 Software
The Audio Control Unit provides the diagnostic tools described in the following sections.
21.1.2.1 Current Status of the Health Status of the Network
A quick diagnostic check on the current health of the network is available via the
ConfigurationÆSystemÆNetworkÆDiagnosticsÆLoop-test menu.
Tx shows the number of messages transmitted by the Audio Control Unit round the network loop. Rx shows the number of these messages that it receives back again. If the network is working correctly these two numbers should be equal.

Page 97 of 138
VAR8-ACU and Variants - Operation, Commissioning, Fault Finding, and Maintenance Guide
The fault code displayed by the Audio Control Unit indicates which channel is affected and where the isolation has occurred and is of the form:
NET-Y/XX AUD RECOVERED
Y= Network Audio Channel (1, 2, 3) on which fault occurred
XX=Address of Slave Unit where isolation occurred
So if the report was NET-3/01 AUD RECOVERED. This would mean that an audio fault has occurred on
Audio Bus-3 between Slaves 1 and 2 and it has been successfully recovered by isolating the faulty segment.
It is also possible to disable the Audio Loop Recovery Mechanism via the following menu. This is useful when fault finding and when commissioning a system.
Menu: ConfigurationÆSystemÆRouterÆMiscÆAudio recovery
21.1.2.3 Data Loop Failure
When a data loop failure occurs the following fault code is always reported at the Audio Control Unit:
INT-01 LOOP FAIL
Because the system instantly recovers communications to all Slaves automatically there may be no other fault reports from which one can diagnose the location of the fault.
To facilitate pinpointing of the faults various diagnostic facilities are available in the
ConfigurationÆSystemÆNetworkÆDiagnostics menu.
The technique is as follows: select incremented when the Slave fails to respond to a message from the Audio Control Unit.
3. If you press SELECT this will clear all counts to zero.
4. The screen displays the Slave addresses from left to right with a counter underneath each one. The count increments every time the Slave is polled and fails to respond. It can quickly be seen which Slaves are failing to respond. These are on one side of the faulty connection.
5. Next, select the Tx-Dir facility and change the direction to DOWNSTREAM ONLY
6. Then select the Slv-t/o (Slave-Timeouts) facility.
7. Press SELECT to clear the count to zero.
8. You can then see which Slaves are failing to respond in the other direction. These are on the other side of the faulty connection.
9. Once the fault is repaired, the Tx-Dir should be returned to BI-DIRECTIONAL. All Slave faults should be cleared via the Audio Control Unit and, finally, the Audio Control Unit faults cleared.

Individual input sources can be monitored on the loudspeaker and a simple bargraph via the following menu.
Menu: TestÆMonitorÆAudioÆInputs
Audio monitoring affects only the LCD display of the unit, i.e. all fault-monitoring activities continue to take place in the background. The status of the LEDs and external outputs are unaffected.
The level displayed is dB (FS). This is dBs relative to digital Full Scale. Typically the input gain should be set so that input signal peaks are in the range –10 to –20dB (FS) to allow enough headroom within the Router.
The monitored audio level is adjustable by the rotary encoder. Note that this volume control affects only the monitor audio level and not the level of the alarm sounder, which shares the same amplifier and speaker.
21.2.4 Sounder and Lamp Test
It is possible to perform a test of all LEDs and sounder on the unit front panel via the following menu.
Menu: TestsÆLamps
LEDs are turned off, then on in sequence while the sounder is turned on and off. The menu will be locked during the test. On completion of the test, normal LED and sounder operation resumes.

24 Fault Indication and Fault Finding
Refer to Section “ 24.6 System Fault Finding Guide ” for fault codes and recommended actions.
When the system has no faults present, the Audio Control Unit displays the current time and date on the
LCD display, and indicates that the system is healthy.
If a fault occurs on a particular unit, then the unit displays text describing the fault. A display of the fault is alternated with a display of the current date and time. In the event of multiple faults each fault is displayed in sequence, while alternating with the date and time display. Faults are time and date stamped as they occur and added to the fault log.
No Fault Fault Indication
When a fault is detected at the Audio Control Unit, the built-in loudspeaker emits an alarm tone and the front panel ‘fault’ LED flashes. fault
Sounder
The Audio Control Unit regularly interrogates all Slave Units for faults, and indicates its own faults, network faults, and the presence of faults of Slaves in a similar manner, as described above.
If one or more faults are detected from a Slave Unit, then the Audio Control Unit logs a single fault identifying the Slave Unit. It does not detail the particular fault. The user needs then to interrogate the Slave Unit for details of the fault. This can be done at the Slave Unit itself, or from the Audio Control unit.

25 Maintenance
To comply with BS5839 Part 8: 1998 (a Code of Practice - a recommendation) and BS EN60849: 1998 (a
Specification - a requirement), it is important that the system as a whole is operated and maintained appropriately. Please refer to these standards for detailed information.
The following routine and special maintenance activities are required, and performed by personnel defined as follows:
• ‘End user’ is the owner of the system;
• ‘Person in charge’ is the person operating the system;
• ‘Responsible person’ is the person who has been given responsibility for the system.
25.1 Training
All the standards emphasise the importance of using trained and qualified personnel.
so that reliable fault histories can be used to provide warning of pending system failures through fault trends.
An engineer needs training to appreciate the importance of this administrative function otherwise it may not get done.
It is worth noting that, as real fire conditions are infrequent, personnel involved in the operation of the system should be retrained on a regular basis.
25.2 Records
The end user or a maintainer contracted by the end user is required to keep appropriate records including installation records, and log book including maintenance records.
BS EN60849 requires that the records comprise as a minimum: a. Details of the locations of all items of equipment. b. ‘As installed’ performance measurements of the system including:
• Measured loudspeaker loading per circuit in emergency mode;
• Settings of any adjustable items within the system, including the output level of power amplifiers;
• Sound pressure levels;
• Intelligibility measurements.
A stiff-covered log book, in which all usage of the system and all fault occurrences are recorded, together with all available automatically produced records, to include: a. Dates and times of usage of the system; b. Details of tests and routine checks carried out; c. Time and date of each fault occurrence, as reported in the fault log; d. Details of the fault found and the circumstances of it being found, for example during routine maintenance; e. Action taken to rectify or remedy any faults; f.

BS EN60849 requires a stiff-covered maintenance manual containing documented procedures that deal with the maintenance and re-test in accordance with the manufacturer’s recommendations and relevant national and international standards, and it recommends a minimum of two scheduled maintenance inspections each year.
Each day, the System should be checked for indication of normal operation as part of the fire alarm system routine maintenance. If there is a remote indicator panel for the VA system, this should also be checked.
25.3.1.2 Weekly Attention
On a weekly basis, the fire detection system should be activated and the VA system checked to ensure it operates under alarm conditions. The System should be checked for indication of normal operation and, if there is a remote indicator panel for the VA system, this should also be checked.
25.3.1.3 Monthly Attention
If an automatically started emergency generator is used as part of the standby supply, then it should be started up once each month by a simulation of a failure of the normal power supply. It should be allowed to energise the fire alarm supply for a continuous period of at least 1 hour. The System should be monitored to identify any malfunctioning caused by the use of the generator.
25.3.1.4 Quarterly Inspection and Test
The responsible person should ensure that every 3 months a competent person carries out the following checks:
1. Entries in the log book should be checked and any necessary action taken.
2. The service life of the internal RTC back-up battery should be checked and replaced if it exceeds 5 years.
3. All fault indicators and their circuits should be checked, preferably by simulation of fault conditions. The
VAR8-ACU should be visually inspected for signs of moisture ingress and other deterioration.
Any defect should be recorded in the log book and reported to the responsible person, and action should be taken to correct it.
On completion of the work, a Certificate of Testing should be completed and given to the responsible person.
25.3.1.5 Annual Inspection and Test
The responsible person should ensure that a competent person carries out the following check and test sequence every year:
1. The inspection and test routines detailed in Section “
25.3.1.4 Quarterly Inspection and Test ”.
2. A visual inspection should be made to confirm that all cable fittings and equipment are secure, undamaged and adequately protected.
Any defect should be recorded in the log book and reported to the responsible person, and action should be taken to correct it.
On completion of the work, a Certificate of Testing should be given to the responsible person.
