3Mechanical
The ZoneSense FACP has an ABS (BX1) or Metal (BX10) enclosure that meets IEC529:1989
IP30 classification. The enclosure houses the Main Control Board (which has all the controls /
indicators, power supply / battery charger circuitry mounted directly onto it), mains transformer
and batteries. All can be easily removed to allow the cabinet assembly to be fixed to the building
structure without obstruction.
3.1 Locating the FACP
The FACP MUST be installed in an area that is NOT subject to conditions likely to affect its
performance e.g. damp, salt-air, water ingress, extremes of temperature, physical abuse, etc.
It should be:
At eye height;
Easily accessible; and
In a prominent position within a building. Typical locations are the first and most obvious
point of contact for emergency services, e.g.; an entrance foyer; the hallway of a building
at ground floor level; or a security situation that is likely to be permanently monitored.
3.2 PCB Removal / Replacement
If the PCB has to be removed the following precautions must be observed;
Removing the door will provide better access to the board/s and ensure the hinges are
not accidentally stressed. To remove swing the door open and push upwards at the
hinges as indicated in the following assembly drawing.
Personal anti- static procedures must be followed.
Disconnect all wiring; carefully remove the retaining screws at each corner of the bridge
all the while taking care not to damage any of the components.
Place the bridge into an anti - static storage once removed.
3.3 Removing the Knockouts
Carefully decide how the wiring will be brought into the panel then remove the required knock-
outs for the bushes and cabling.
The knock-outs should be removed with a series of sharp taps around the rim of the knock-out
impression using a flat broad-bladed screwdriver.
Exercise some care during this process as the use of excessive force could damage the
enclosure around the knock-out.
If a knock-out is removed always ensure, the hole is filled with a good quality cable gland. Any
unused knock-outs must be securely blanked off.

4.2 Mains wiring
The requirement for the ‘Mains’ supply to the Fire Alarm Control Panel is three core cable ( no
less than 1mmand no more than 2.5mm) fed from a fused 3A isolating switched spur which
should be secured from unauthorised operation and be marked 'FIRE ALARM: DO NOT SWITCH
OFF’.
4.3 Connecting the Mains
The incoming Mains cable should be brought into the Panel at the top right hand side of the
enclosure and correctly terminated to the fuse / terminal block. Wired to this terminal block is the
mains transformer that reduces the mains to the required 32VAC secondary voltage.
Before switching on the Power Supply the Earth MUST be connected to the chassis earth
terminal as shown in the following diagram.
All earth cabling must be terminated to the Panels Chassis Earth Terminal in a Star
configuration.
Each additional earth cable must be terminated with an M4 nut and M4washer.
An additional M4 nut and washer are fitted to the earth terminal for installers to connect
their mains earth

5Power Supply
The power supply equipment (PSE) consists of a primary power supply and battery standby if
required.
The primary power supply derives the appropriate voltages to run the FACP and charge the
batteries (if fitted) from the available mains supply. In the event of a failure of the mains supply
the PSE automatically switches over to the standby rechargeable sealed lead acid batteries to
power the FACP. During this time the FACP will indicate there is a power fault (Power Fault LED
flashes) and continue to function normally. When the mains is restored the PSE automatically
switches back to the primary power source. If the mains interruption is of such duration that the
standby battery capacity is reduced to such a level as dictated by the battery manufacturer the
FACP will shut down.
The maximum size batteries that can be accommodated within the enclosure are 7A/Hr.
5.1 Primary Power Supply
The primary power supply operates from 204 to 265VAC, is capable of producing a nominal
24VDC at up to 1.6 amps. It consists of a transformer mounted to the rear of the enclosure and
appropriate circuitry located on the control card.
A DC to DC converter converts the 24VDC to 3.3VDC to power the FACP microprocessor.
5.2 Standby Power Supply
The optional backup battery supply is required to be able to maintain FACP quiescent operation
for 24 hours (72 for non monitored applications) in the event of mains power failure, then supply
full alarm load for a period of 30 minutes.
The standby power supply has a low voltage disconnect to prevent the batteries from being
discharged below 21VDC.
Requirements of the battery charger are to:
Ensure the batteries are charged according to the manufacturers specifications.
To provide a facility to measure the battery voltage, and detect a missing or damaged
battery
To provide a facility to turn off the charger output.
To provide a facility to measure the charger voltage
To ensure the battery connection is protected against reverse or short circuit connection
To ensure the battery does not discharge through the battery charger, when the charging
voltage is less than the battery voltage.
5.2.1 Setting Battery Monitoring
If the optional backup battery supply is not fitted to the FACP the battery monitoring is disabled
(at access level 3) by using switch 1 of the 4 way DIP switch SW10. Switch is ON to enable
monitoring, and OFF to disable monitoring.
5.3 Power Faults
Power faults are detected within 10 seconds and displayed by the FACP. Faults detected are;
Loss of mains and if batteries are fitted and monitoring enabled.
Missing or damaged batteries
Battery voltage below 21.6V
Charger voltage in excess of 28.8VDC
Loss of charger voltage

fitted), plus the normal operational current totals 945mA.
5.5 Powering Up and Down Sequence –Batteries Fitted
Given the current involved on “power up” the following procedure MUST be followed;
Power Up
Connect the batteries –white cable +ve red terminal to black terminal –ve ( places the
batteries in series ) red cable to red + ve terminal, black cable to –ve black terminal.
Switch on the mains supply
Power Down
Switch off the mains supply
Remove the positive (+ve) lead from the batteries
Note: After a “Power Down” the mains supply and batteries MUST be left disconnected
for at least 1 minute to allow any residual capacitive charge to be dissipated. If this process is not
followed a SYSTEM FAULT could be incorrectly indicated

6.4 Zone Circuits (TB2 & TB800)
A maximum of 32 x 24volt Optical / Heat Detectors and / or Manual Call Points mixed in any
order can be fitted to each circuit. An output current of 4mA for each circuit with capacitive EOL is
considered to normal and in a worst case or fault S/C condition each circuit is current limited to a
maximum of 25mA.
The Main Control Board has up to eight (8) zone circuits that connect to the 24VDC conventional
fire detectors. The maximum number of detectors and MCP’s that can be supported will be
influenced by the quiescent current draw of the detectors and MCP’s being fitted.
The wiring for each zone circuit should be connected to the relevant terminal block on the Main
Control PCB and if screened the screens terminated at the panel's base earth post.
An End of Line 10F Bi-polar Capacitor must be connected across the terminals of the last device
on each circuit to allow the circuit to be monitored. Zones that are not used must also have an
End of Line capacitor fitted to the terminal block at the panel.
The detector interface is compatible with Apollo and Hochiki conventional detectors (refer to the
list of compatible devices). Reset time is 2 seconds. Each zone circuit will function as follows.

6.4.1 Operating Conditions
All zone fault conditions are non-latching hence cleared when the reset control is activated, and
are re-announced within 10 seconds if the fault condition still exists.
Zone alarms are only configured as latching. This means that irrespective of the condition of the
zone itself the alarm condition can only be cleared when the front panel reset control is activated,
Zones can also be configured to have an associated output delay timer. The delay time can be
set from 30 seconds up to 7 minutes and 30 seconds. If the zone is configured with a delay then
the activation of the alarm outputs and ancillary output is delayed accordingly. A front panel
control is provided to override the delay. This is associated with an indicator which is illuminated
when the delay timer is active.

Page 11
ZONESENSE EN54 INSTALLATION COMMISSIONING & OPERATION
Note: The activation of the remote output relay is not affected by the
delay timer.
Typically MCP’s must be fitted with series resistors (470 or 680 ohm), so as when the MCP is
activated a short circuit is not present on the zone circuit.
The zone circuits can be disabled by using the front panel controls Once disabled, the zones do
not cause the activation of the alarm outputs, remote relay output or ancillary output.
6.4.2 Detector Removal Facility
This facility allows for up to 20 detectors to be removed from their bases at any one time. If a
detector head is removed a fault will be indicated on that zone and all the other devices retain the
ability to initiate an alarm. This facility requires a Schottky diode to be fitted as per Figure 11
Note: Schottky diodes having a voltage drop of 0.2 –0.3 of a volt have to be installed
across L1 in and L1 out on the detector base. The limitation on the number of heads that can be
removed is a direct result of the cumulative effect of the voltage drop across each diode.
Diodes will not be required if the head removal facility is not required.
6.5 Outputs –Monitored Alarm Outputs (TB3, TB801)
The Main Control Card has four (4) parallel PTC protected monitored outputs typically used to
power electronic type sounders and are referred to as alarm outputs. Each output is nominally
rated at 250mA @ 24VDC and monitored for open and short circuit conditions when the output is
not activated.
Monitoring is achieved by the sensing of the End of Line (EOL) 10kΩ resistors and is independent
of the loading of bells and sounders. The monitoring is forward biased and requires diodes to be
fitted in series with each bell and sounder. Faults on the monitored outputs will be indicated by
the FACP within 60sec.

Note: The 2 zone and 4 zone version has 2 alarm outputs fitted while the 8 zone version has
4 alarm outputs fitted.
The alarm outputs are activated by the:
Class change input
Alert input
Front panel evacuate control, silence/resound control
Zones entering the alarm condition. If there are no delays programmed the alarm outputs
will be activated within 3 seconds of the zone entering the alarm condition.
General Conditions
Zones entering the alarm condition will always activate the alarm outputs. Alarm outputs can be
de-activated by the silence/resound control and/or a reset of the zone(s) in alarm.
The front panel Evacuate control will always activate the alarm outputs. Alarm outputs can be de-
activated by the silence/resound control and/or a reset
If the Class Change input is ON and there are no zones in alarm and the front panel evacuate
control is not active, then the alarm outputs will be activated.

Page 12
ZONESENSE EN54 INSTALLATION COMMISSIONING & OPERATION
If the Alert input is ON, Class Change input is OFF, there are no zones in
alarm and the front panel evacuate control is not active then the alarm outputs will pulse at the
rate of 1sec ON and sec OFF.
The Alarm outputs can be disabled by using the front panel control. Once disabled, the outputs
will remain off until they are re-enabled. A front panel indicator associated with the output is
illuminated when these outputs are disabled.
6.6 Outputs –Open Collector (TB4)
There are four unmonitored open collector type outputs. Each output is capable of switching
40mA of output current and withstand a short circuit condition to the common +24VDC output
without damage.
Note: The common +24VDC feed is current limited to 170ma by a PTC and monitored at the
terminal block. If there is an over current situation, then the PTC will activate and a fault will be
reported at the FACP

6.7 Remote Output –(TB4/1)
The operation of this output is identical to the operation of the remote output relay.
6.8 Fault Output –(TB4/2)
The operation of this output is identical to the operation of the fault output relay.
Note: This output will be normally energised, and de-energised to signify a fault
condition.
6.9 Ancillary Output –(TB4/3)
Ancillary Output is a un-monitored open collector output activated when any of the zones report
an alarm condition. The activation of this output is subject to any delays that may be configured.
This output can be disabled by using the front panel controls. Once disabled the output will
remain off until it is re-enabled. The ANCILLARY OUPUT front panel indicator is illuminated when
this output is disabled.
6.10 Reset –(TB4/4)
Reset is a non-monitored open collector output activated for 15sec with the FACP reset.
6.11 Auxiliary Power Output –(TB4/5)
This +24VDC output with an associated return is monitored at the terminal block and current
limited to 150mA @ 24VDC by a PTC. If an over current situation occurs fault will be indicated.
6.12 Outputs –Volt Free Relay (TB5)
There are two voltage free relay outputs, the Remote output, and the Fault output.
6.12.1 Remote Output Relay
The Remote Output Relay has 1A 30VDC unmonitored voltage free single change over contacts
that are activated when any zone circuit reports an alarm condition. The front panel indicator
“Remote Output On” is illuminated when the output is activated and is reset via the front panel
reset control.

Page 13
ZONESENSE EN54 INSTALLATION COMMISSIONING & OPERATION
The output can also be disabled by using the front panel controls. Once
disabled the relay will remain off until re-enabled and the front panel indicator “Remote Output
Disabled” is illuminated.
6.12.2 Fault Output Relay
The Fault Output Relay is energised if the FACP is operating normally and has unmonitored 1A
30VDC voltage free single change over contacts. The output can be disabled by using the front
panel control. Once disabled the relay will remain on until it is re-enabled and the FAULT
OUTPUT front panel indicator is illuminated when this output is disabled.
If a fault is present on the FACP the output relay is de-energised and remains de-energised until
the fault conditions have cleared. There are a number of front panel fault indicators that detail the
nature of the fault. These are:
Power Fault –fault relating to the power supply.
System Fault –fault relating to the operation of the FACP.
Auxiliary Power Fault –fault relating to the auxiliary power output. Individual zone fault
indicators.
Alarm Outputs.
Faults associated with ancillary modules –missing, type mismatch or extra.
Note: #1: All faults are non-latching, except for system fault.
Note: #2 Faults associated with zones are cleared on a reset condition.
Note: #3 Power faults are indicated

6.13 Watchdog Circuitry
The Main Control Board has watchdog circuitry external to the main processor that strobes the
main processor at intervals equal to or less than 1 second. If the 1 second interval is not met the
main processor is reset by the Watchdog circuitry, the system fault and common fault indicators
will be illuminated and the buzzer will sound. These indicators remain illuminated until reset.
If the main processor fails to successfully restart after six to twelve reset operations the processor
is held in reset. In the situation where the processor is held in reset, the buzzer will sound, the
system fault and fault indicators will flash at 0.25Hz, that is On for 2 seconds and Off for 2
seconds.
6.14 Checksum
At periods not exceeding one hour, the main processor performs a checksum operation on the
application software and configuration data. If the application software or configuration data has
become corrupted then the main processor enters the reset state, the buzzer will sound, and the
system fault / fault indicators will flash at 0.25Hz, that is On for 2 seconds and Off for 2 seconds.

6.15 Enabling and Setting Delay Timing
Note: Delay enabling and timing can only be set at access level 3
Enabling
An 8 way DIP switch is used to enable the delays on a zone by zone basis. Switch 1 corresponds
to zone 1; Switch 2 corresponds to zone 2 and so on.
Switch OFF position disables delay, and the ON position enables delay. For example if switch 1
is OFF, and switch 2 is ON, then zone 1 has delays disabled, and zone 2 has delays enabled.
Setting the Delay Time
If delays are enabled the delay time is the same for all zones. The length of the delay is set by
adjusting the 4 way DIP switch, adjustable from 0 to 8:00 minutes in steps of 30 seconds,

6.16 Setting the Zone Configuration DIP Switches
Note: Zone configuration can only be set at access level 3
In the 2 zone version one 8 way DIP switch is fitted, switches 1 - 4 are used for setting the delay
time, switch 5 enables the delays for zone 1, and switch 6 enables the delays for zone 2.
The 4 zone version is the same as the 2 zone version, with the addition that switch 7 enables the
delays for zone 3 and switch 8 enables the delays for zone 8.
In the 8 zone version an 8 way DIP switch and a 4 way DIP switch are fitted. The 8 way DIP
switch is used the same as the 4 zone version. Switch 1 of the 4 way DIP switch enables the
delays for zone 5; switch 2 enables the delays for zone 6; switch 3 enables the delays for zone 7;
and switch 4 enables the delays for zone 8
