INSTALLATION AND OPERATION MANUAL 25-16732-A November 2019 www.eaton.com
1. Introduction
1.1 Purpose
This manual is intended as a guide for the installation and
commissioning of the BiWire Flexi 2/4/8 Zone Control panel.
The content of this guide is intended to assist the user to
install a fire alarm system and does not specify the detailed
design of the product. The guide assumes a reasonable level of
competency with this type of system.
The installation of this system can only be carried out by
a competent person with relevant current training and
experience, with access to requisite tools, equipment and
information (as stipulated by BS5839).
The design has been carried out in accordance with a quality
management system, which incorporates a set of rules for the
design of all elements of the Control and Indication Equipment
(CIE) and Power Supply Equipment (PSE).
The components of the CIE and PSE have been selected for
the intended purpose, and are expected to operate within their
specification when the environmental conditions outside the
cabinet of the CIE / PSE comply with class 3k5 of
EN 60721-3-3:1995.
2. The BiWire Flexi Fire Detection
& Alarm System
The BiWire Flexi fire alarm system is a highly adaptable
and intelligent product designed with the simplicity of
a conventional fire alarm system, enhanced to provide
multifunction fire detection and condition indication capability.
The Fire panel supports switchable zones that can be
configured for BiWire Mode that has detectors, call points,
sounders, and Visual Alarm Devices (VAD) combined on the
zone, or Conventional Mode (Standard or Intrinsically Safe
Mode) that only allows detectors and call points on the zone.
BiWire Mode eliminates the requirement to have separate
sounder circuits as with standard conventional systems, but
the BiWire Flexi also comes with conventional sounder circuits
to provide a purely conventional solution or a configurable
retro-fit solution.
The BiWire Flexi fire alarm system is certified to EN54 part 2
and part 4 and is designed to meet the recommendations in
BS5839.
The panels have the following optional features as standard:
• FIRE ALARM DEVICES: (EN54 part 2 clause 7.8)
• TEST CONDITION: (EN54 part 2 clause 10)
• Control of fire alarm routing equipment
(EN54 part 2 clause 7.9.1)
• Output to fire protection equipment
(EN54 part 2 clause 7.10.1)
The components of the BiWire Flexi Fire System are
as follows:
• The Fire Panel is available to support 2, 4 and 8 Detection
Zones. Each Zone, when set to BiWire operation, can be
configured with up to 32 input devices (including detectors
and manual call points) and 20 output devices connected via
a single 2-core screened cable.
• Depending on the type of Fire Panel, up to 2 conventional
sounder circuits can be used (see technical specifications
for loading characteristics). Each sounder circuit consists
of two sounder outputs. The total usable sounder outputs
depend on the BiWire or Conventional mode configuration
as outlined on page 11.
• The integrated EN54 part 4 compliant power supply charges
and monitors two 12V 5Ah batteries. The power supply is
capable of providing up to 24-hour standby depending on
the system loading (further information on this can be found
in the Technical information section of this document).
• When a zone is configured as BiWire mode, each zone must
be terminated with an intelligent end of line monitoring
module called the EOLM-3™. When a zone is configured for
Conventional mode, each zone must be terminated with an
EOLM-1 (for backward compatibility). Both EOLM modules
need to be located with the last device on the zone.
• The Fire alarm system has an options interface board to
provide outputs to Fire Protection Equipment (FPE), Fire
Routing Equipment (FRE) and zonal relays. This interface
and the relevant conformance requirements are further
described within this guide.
• The BiWire Flexi panel is only compatible with BiWire Ultra
range of devices for zones configured for BiWire mode,
and is also compatible with the standard Eaton range
of conventional devices on both conventional zones and
sounder circuits. When a conventional zone is configured
for Intrinsically Safe mode then intrinsically safe detectors
can be fitted in conjunction with an isolation barrier (see
technical specifications for more details).

2.1 Control and Indication Equipment (CIE)
The BiWire Flexi Fire Panel is designed as an Analogue
non-addressable system. The panel enclosure is constructed
from PC ABS components.
The front cover is hinged at the bottom and is secured at the
top of the panel by two retaining screws. On the in-side of
the panel a sliding PCB tray makes it easy to remove the tray
without touching the PCB. The back box houses the PSE, the
stand-by batteries and has 29 x 20mm cable access points.
Terminal blocks are positioned to enable ease of connection.
Figure 1 shows the dimensions of the panel.
The Fire Panel comes in 2, 4 & 8 Zone variants. Each of
these variants will operate in the same manner only with a
limited number of zones. Each zone can be independently
configured with a variety of compatible BiWire Ultra devices
or conventional devices (depending on the zone mode)
up to a maximum load of 200mA per zone. BiWire and
conventional devices cannot be mixed together on a zone;
each zone must either have a full complement of BiWire
devices or conventional devices as per the zone mode setting.
A maximum of 32 inputs devices (detectors and/ or manual
call points) and 20 output devices is possible as one BiWire
configuration example; a loading calculator is available to assist
with zone configuration.
Figure 1. BiWire Flexi Fire Panel Dimensions
The panel continuously monitors the state of each zone for
Fire and Fault conditions which are only indicated on the
affected zone. Once a Fire condition is detected on a zone
then the panel turns on the Fire indicators for the zone in
fire and triggers the fire alarm devices across all zones. All
remaining zones will continue to monitor for secondary fires or
fault conditions even though the sounders are operating.
The panel also continuously monitors the state of each
conventional sounder circuit and will report any fault condition
detected on the sounder fault LED.
The panel has multiple non-monitored outputs such as
Auxiliary Output, Fire Relay, Fault Relay, and an Interlink
Relay. These outputs are extended with the option board that
provides additional monitored FRE and FPE outputs, and a
non-monitored relay per zone circuit. The fire panel also has
a monitored input called Class Change. Further information is
contained within this guide.

INSTALLATION AND OPERATION MANUAL 25-16732-A November 2019 www.eaton.com
2.2 Power Supply Equipment (PSE)
The PSE has been specifically designed to operate the BiWire
Flexi Fire Panel and may not be substituted for any other
power source. The PSE is a Switch Mode Power Supply
located within the Fire Panel cabinet as shown below. A
dedicated 230V AC mains supply is required as the primary
source; the supply is fused on the PCB by a 10 amp anti-surge
fuse. In the event of mains failure the PSE will automatically
switched over to the standby battery power source until the
main power source is restored.
The PSE maintains the charge for the two 12V 5Ah sealed lead
acid batteries in a fully charged state. On initial power up the
batteries will charge over a 24 hour period. Dependent on the
charge of the installed battery the system may initially show a
charger or battery fault.
The supply should be clearly labelled ‘FIRE ALARM: DO NOT
SWITCH OFF’ at all isolation points.
PSE faults originating from the following are indicated
by the panel:
• The loss of either power source
• Failure of the charger circuit
• High internal resistance of the battery
Figure 2 shows the location of the power supply. “Individual
Zone Test” on page 25 provides a full technical specification
for the power supply.
Note that the charging circuit will be in its high impedance
state (approximately 3V DC) if no batteries, faulty batteries,
or only one battery is connected. The full 27V DC (nominal)
charging voltage should be present if the correct batteries
are connected.
In order to test for correct operation of the batteries, remove
the mains 230V AC fuse and allow the batteries to settle from
their charging voltage for approximately 5 minutes. The battery
voltage should then be measured using an electronic test
meter and a voltage greater than 24V DC should be present.

6INSTALLATION AND OPERATION MANUAL 25-16732-A November 2019 www.eaton.com
2.3 EOLM-3
Each Zone on the panel that is configured for BiWire mode
must have the intelligent end of line module (EOLM-3™,
Figure 3) fitted to continually monitor each zone for the
presence of fault conditions such as detector head removal,
open or short circuit and for end of line failures even when in a
Fire condition.
For new installations, any Zone on the panel that is configured
for Conventional mode can use the intelligent end of line
module (EOLM-3™) to terminate the zone but the panel will
be limited to only detecting the presence of open or short
circuit conditions to make it backward compatible with the
EOLM-1. All detector head removals will be seen as an open
circuit condition.
The EOLM-3™ module can be installed in the base of the last
manual call point or detector base.
CAUTION
IF THIS DEVICE IS NOT INSTALLED WITH THE CORRECT
POLARITY IT MAY BE DAMAGED WHEN THE PANEL IS
POWERED ON. INCORRECT POLARITY WILL ALSO CAUSE A
FAULT TO BE DISPLAYED ON THE FIRE PANEL
Figure 3. EOLM-3 module
2.4 EOLM-1
Each Zone on the panel that is configured for Standard
Conventional mode must have the intelligent end of line
module (EOLM-1™, Figure 4) fitted to continually monitor each
zone for the presence of fault conditions such as detector
head removal, open or short circuit and for end of line failures
even when in a Fire condition.
The EOLM-1™ module can be installed in the base of the last
manual call point or detector base.
CAUTION
IF THIS DEVICE IS NOT INSTALLED WITH THE INCORRECT
POLARITY A FAULT WILL BE DISPLAYED ON THE FIRE PANEL
Figure 4. EOLM-1 module
2.5 EOLR
Each Zone on the panel that is configured for Intrinsically Safe
Conventional mode must separate the intrinsically safe devices
from the panel using the intrinsically safe barrier MTL5561. The
last device on the zone must be terminated with a 5K1 End of
Line Resistor to ensure proper fault and fire monitoring
of the zone.
Any Sounder Circuit on the panel that is being used for
Intrinsically Safe Sounders must separate the intrinsically safe
alarm devices from the panel using the intrinsically Safe Barrier
MTL7778ac. The last alarm device on the sounder output
must be terminated with a 6K8 End of Line Resistor to ensure
proper fault monitoring of the circuit.

INSTALLATION AND OPERATION MANUAL 25-16732-A November 2019 www.eaton.com
2.6 System Wiring
This section describes how different types of device can be
incorporated into a mixed system with zones configured as
either BiWire Ultra or Conventional mode. Figure 5 shows a
typical system with both BiWire and Conventional zones.
For zones configured in BiWire mode the zone can be wired
for both BiWire detection (detectors and call points) and
BiWire alarm (wall/base sounders, VADs and I/Os) devices
terminated with an EOLM-3 embedded in the last device.
Intrinsically safe and standard conventional detection and
alarm devices cannot be wired onto a BiWire zone.
For zones configured in Conventional mode the zone is wired
for Conventional detection (detectors and call points) devices
only and must be terminated with an EOLM-1 or EOLM-3
embedded in the last device. Intrinsically safe conventional and
BiWire detection and alarm devices cannot be wired onto a
conventional zone.
For zones configured in Intrinsically Safe Conventional mode
the zone is wired into the MTL5561 intrinsically safe barrier
and all Intrinsically Safe Conventional detection (detectors
and call points) devices are wired into the barrier with a 5K1
EOLR embedded in the last device. Standard conventional and
BiWire detection and alarm devices cannot be wired onto an
intrinsically safe conventional zone.
Figure 5. BiWire Flexi System Wiring Diagram
For sounder outputs used with standard conventional alarm
(wall/base sounders, VADs and I/Os) devices the circuit must
be terminated with 6K8 EOLR embedded in the last device.
Intrinsically safe alarm devices cannot be mixed with standard
conventional alarm devices as an intrinsically safe barrier must
be used (see below). BiWire alarm devices cannot be wired to
a conventional sounder output.
For sounder outputs used with Intrinsically Safe alarm devices
the circuit must be wired into the MTL7778ac intrinsically safe
barrier and all Intrinsically Safe Conventional alarm (wall/base
sounders, VADs and I/Os) devices are wired into the barrier
with a 6K8 EOLR embedded in the last device. Standard
conventional alarm devices cannot be mixed with intrinsically
safe alarm devices. BiWire alarm devices cannot be wired to a
conventional sounder output.
For zones configured as Standard or Conventional mode the
zone can be wired for detection (detectors and call points)
devices terminated with an EOLM-1 and alarm (wall/ base
sounders, VADs and I/Os) devices on separate circuits.

2.8 Control Panel Inputs and Outputs
Figure 7 shows the panel wiring in a typical mixed BiWire and
Conventional installation. The following paragraphs describe
the outputs from the panel.
Figure 7. Panel Wiring diagram
Auxiliary Output
The Auxiliary Output is a 30V dc output provided at the panel
to power ancillary equipment (Figure 8). The current consumed
by this output must be considered when calculating battery
standby times. The contacts are not monitored.
Class Change
The sounders can be operated by an external volt free
contact (Figure 9). A short circuit at this terminal will activate
non-latching sounders (no indication will show on the fire
alarm panel). The sounders will automatically silence when the
short circuit is removed. This is sometimes used for schools at
class change times.
IMPORTANT
IF CLASS CHANGE IS USED AND THERE ARE ZONAL RELAY
UNITS (BWEXTR 24V OR 230V) FITTED TO THE SYSTEM, BE
AWARE THESE WILL CHANGE STATE AND REQUIRE A PANEL
RESET TO RETURN TO QUIESCENT MODE.
WARNING
NO VOLTAGE SHOULD BE APPLIED TO THIS INPUT
Figure 8. Auxiliary Output Terminals
Figure 9. Class Change Terminals

10 INSTALLATION AND OPERATION MANUAL 25-16732-A November 2019 www.eaton.com
Fire Relay
The fire relay provides a set of fused volt free changeover
contacts, which operate in the event of a fire condition (Figure
10). These contacts are not monitored. The fire relay can be
used as Fire Alarm Routing Equipment or Fire Protection
Equipment outputs.
Fault Relay
The fault relay provides a set of fused volt free changeover
contacts, which operate in the event of a fault condition
(Figure 11). These contacts are not monitored. This relay has
been configured to be in fail safe mode, so in the event of
total power loss the relay contacts will be active.
Fault Relay reporting:
• Battery fault
• Mains fault
• Charger fault
• Impedance fault
• Zone faults:
• Open circuit
• Short circuit
• Detector removal
• Sounder fault
• Repeater fault
• FRE fault
• FPE fault
Interlink Relay
The Interlink Relay in conjunction with a non-latching zone
can be used to link two BiWire Flexi fire panels together
(Figure 12) or to link a BiWire Flexi to a BiWire Ultra panel. It is
recommended to use a non-latching zone in the BiWire mode
and fit the EOLM-3 at the interlink relay of each panel.
WARNING
WHEN A ZONE IS BEING USED FOR INTERLINKING
PANELS, NO OTHER DEVICES ARE PERMITTED ON THAT
ZONE.
When an alarm is activated on one of the panels, the
appropriate zone will indicate on the panel detecting fire and
the interlink relay will activate. This is turn will activate the
non-latching zone on the other panel and both panels will be in
fire and all sounders on both panels will be activated. To reset
both panels, one of the panels would be manually soft reset,
which would cause the non-latching zone on the other panel to
reset as well. This would reset both panels.

INSTALLATION AND OPERATION MANUAL 25-16732-A November 2019 www.eaton.com
Detector Zone Inputs
Each zone is configured by default to BiWire mode and is
provided with an EOLM-3 fitted inside panel.
For zones that need to be in BiWire mode the EOLM-3 must
be removed from the panel and fitted to the last device on
each zone (“Panel Wiring diagram” on page 9). Any unused
BiWire zones must be terminated inside the panel by the
EOLM-3 otherwise the zone will go into fault condition.
For zones that need to be in Standard Conventional mode then
for new installs the EOLM-3 must be removed from the panel
and fitted to the last device on each zone (Figure 7 on page
9), for retro-fit installs that already has an EOLM-1 fitted at
the end of the zone then the EOLM-3 needs to be removed
from the panel and not used, for retro-fit installs without an
EOLM-1 then the EOLM-3 must be removed from the panel
and used to replace the termination in the last device on
the zone. Any unused standard conventional zone must be
terminated with either an EOLM-3 or EOLM-1.
For zones to be configured in Intrinsically Safe Conventional
mode the EOLM-3 must be removed and replaced by a 5K1
resistor (not supplied) and fitted in the last device at the end of
zone after the intrinsically safe barrier. Any unused intrinsically
safe zone must be terminated by the 5K1 end-of-line resistor.
It is recommended that any zone that is not in use should
remain in the factory default configuration of BiWire mode
with the EOLM-3 fitted in the panel.
On a zone configured in Intrinsically Safe Conventional mode
call points must not be wired after a detector. This is to comply
with Addendum to BS 5839 PT1 Amendment 6317 which
requires that the removal of a detector does not isolate a
manual call point.
On zones configured in BiWire or Standard Conventional mode
there is no restriction regarding the wiring of a call point.
Conventional Sounder Circuits
Each sounder circuit consists of two sounder outputs.
For 2 and 4 zone panels, the following rules apply:
• All Zones in BiWire Mode = 0 Sounder Outputs
• Half Zones in BiWire and Half in
Conventional Mode = 2 Sounder Outputs
For 8 zone panels the following rules apply:
• All Zones in BiWire Mode = 0 Sounder Outputs
• 1-4 Conventional Zones = 2 Sounder Outputs
• 5-8 Conventional Zones = 4 Sounder Outputs
Each sounder circuit must be terminated by a 6K8 resistor
whether the alarm devices are standard or intrinsically safe
in order for the panel to detect Short and Open circuit faults.
Even if the conventional sounder circuits are not in use they
must be terminated by the 6K8 resistors inside the panel.
Repeater I/O
Each repeater has its own mains supply and standby battery.
The repeater output is designed to connect to another panel
configured as a repeater using the RS485 protocol.
The repeater would follow the indication of the main Panel
showing faults, fires and disablements (Figure 13).
Figure 13. Repeater Panel Connection
2.9 Option Board (FRE/FPE/Zonal Relays)
The options board is an additional daughter card that provides
outputs to Fire Protection Equipment (FPE), Fire Alarm Routing
Equipment (FRE) and Zonal Relays.
Fire Alarm Routing Equipment (FRE)
The FRE output is designed to activate during a fire event and
is connected to phone diallers and/or Building Management
Systems. When the FRE option board is fitted SW12-1 dip
switch is set to Fitted. See figure 6. The output complies with
EN54-2 clause:
• Outputs to fire alarm routing equipment (option with
requirements)
Fire Protection Equipment (FPE)
The FPE output is designed to activate during a fire event
and when connected to external devices drive door release
mechanisms, fire screens, sprinkler systems, and gas release
systems. When FPE option board is fitted SW12-1 dip switch
is set to Fitted. The output complies with EN54-2 clause:
• 7 .10.1 Outputs to fire protection equipment (Type A)
Zonal Relay Contacts
Zonal relay contacts are volt free and do not provide any
voltage. The relays are selectable to be either set to C/NO or
C/NC. The zonal relays are designed to follow the fire condition
of the associated zone circuit on the Main board.

Connecting the Mains Supply
The mains supply should be exclusive to the fire alarm as
detailed in BS5839. A plug and socket is not satisfactory.
We recommend that a switched double pole fused spur unit is
used for the sole use of the fire alarm system and should be
clearly marked with:
FIRE ALARM DO NOT SWITCH OFF
Before connecting the fused spur to the PSE, slide the ferrite
core (supplied with the panel) over the cable as shown in
Figure 21.
Connect the fused spur to the input marked MAINS on the
PSE, observing correct wiring regulations.
NOTES
OBEY VOLT DROP LIMITATION WHEN SIZING CABLES.
USE ONLY APPROVED CABLE TYPES.
DO NOT TIGHTEN TERMINAL CONNECTOR SCREWS
TOO TIGHT.
KEEP POLARITY THROUGHOUT. NON COLOURED
CONDUCTORS SHOULD BE PERMANENTLY MARKED.
Figure 21. Mains Supply connection to PSE
Connecting the Battery Supply
A Battery cover is supplied to prevent accidental contact with
the battery terminals and gives additional useful information.
The battery cover can be moved out of the way as indicated in
Figure 22.
Connect the spade connectors of the two wire battery cable
and the single wire battery cable as illustrated in Figure 21
Do not connect the plastic socket end of the battery cable to

Battery Connections
1. Connect the BLACK battery wire to the BLACK (-)
battery terminal of Battery B (Figure 23)
2. Connect the RED battery wire to the RED (+) battery
terminal of Battery A (shown as grey)
3. Connect the link cable between the two
remaining terminals
Connecting the Zone Cables
Connect the cables (clearly labelled with the zone numbers) to the
appropriate zone +/- terminals, observing the correct polarity. Figure 24
shows how different types of zone can be connected to a BiWire Flexi
Fire Panel.
If any of the zones are not used then the EOLM-3 must
remain fitted to the terminals of that zone to ensure the
system remains fault free.
CAUTION
DO NOT USE A HIGH VOLTAGE TESTER WHEN WIRING IS
CONNECTED TO ANY ELECTRONIC EQUIPMENT.
NOTE
IT IS IMPORTANT THAT ZONE CABLING IS CONNECTED
TO THE CORRECT ZONE INPUT OTHERWISE ANY FIRE OR
FAULT INDICATION ON THE PANEL WILL NOT MATCH THE
ZONE MAP OF THE SITE, AND WILL NOT BE COMPLIANT
WITH BS5839

INSTALLATION AND OPERATION MANUAL 25-16732-A November 2019 www.eaton.com
Connecting the Input/Output Cables
Connect the cables (clearly labelled with the external
equipment reference) to the appropriate input or output
terminals, observing the correct polarity where applicable.
CAUTION
REFER TO THE INSTALLATION GUIDES OF ANY EXTERNAL
EQUIPMENT. CHECK THE CORRECT WIRING POLARITY
AND THAT THE EQUIPMENT IS COMPATIBLE WITH THE
BIWIRE FLEXI PANEL BEFORE POWERING
UP THE SYSTEM.
Interlinking Two Panels
Wire the two panels together as shown in Figure 25.
The EOLM-3 must be fitted for the zone circuits on both
panels to be monitored for fault conditions.
The 680ohm resistor must be fitted so that the zone input will
detect the fire condition and activate its fire alarm devices.
In order for the Interlink to operate correctly the zone inputs
on both panels being used for interlinking must be set to
unlatched, therefore the associated switch on SW4 must be
set to the Unlatched Zone x setting (see Figure 26).
WARNING
THE UNLATCHING SETTING IS NOT TO BE USED WITH
DETECTION ZONES AS THIS WILL MAKE THE PANEL
NON-COMPLIANT.
NOTE
NO OTHER DEVICES ARE TO BE CONNECTED TO A ZONE
CONFIGURED FOR INTERLINKING.
Connecting a Repeater Panel
Connect the cables from the repeater panel to the Repeater
terminals on the main board of the fire alarm panel, observing
the correct polarity (see Figure 24).
To enable the repeater output switch 2 of SW12 on the panel
main board must be changed to the Repeater Output On
setting (see Figure 27)

3.4 Option Board Installation
Connecting the FRE and FPE Outputs
Connect the cabling from the fire alarm routing equipment
and fire protection equipment to the relevant terminals on the
option board (Figure 28).
As these outputs are monitored for short circuit and open
circuit faults conditions, the 6K8 resistor supplied should be
installed at the external equipment and not at the option
board terminals.
Figure 28. Option Board wiring diagram
NOTE
IF EITHER THE FRE OR FPE IS NOT BEING USED THEN THE
6K8 RESISTOR SHOULD BE FITTED AT THE APPROPRIATE
TERMINAL ON THE OPTION BOARD.THIS PREVENTS
ERRONEOUS FAULTS CONDITIONS BEING DISPLAYED ON
THE PANEL.
Connecting the Zonal Outputs
Connect the cabling from the external equipment to the
relevant zone terminals on the option board.
These outputs are not monitored so there is no need for a 6K8
termination resistor.
Change the jumpers on the zonal relays to get them to operate
in either normally open or normally closed during a fire
alarm condition.

3.6 Detector Fitting
All detector heads should now be fitted to the bases (following
the device installation guide), prior to the installation
being tested.
The BiWire detectors can be configured for either latched or
non-latching fire condition.
When the detectors are configured for latched mode then care
must be taken that before any zone is re-enabled that a walk
round of the zone is carried out to check that all detectors and
manual call points are not latched in the fire condition.
If there are no detectors or manual call points showing the fire
condition then the zone can be re-enabled at the panel.
WARNING
FAILURE TO FOLLOW THE INSTRUCTIONS ABOVE
WILL RESULT IN THE PANEL ENTERING A FULL ALARM
CONDITION WHICH WILL EVACUATE THE SITE AND
ACTIVATE ANY OTHER EQUIPMENT ATTACHED TO THE
FIRE ALARM SYSTEM.
3.7 Installation Testing
Initial Power-up Check
Power up the panel by engaging the fuse spur to supply
mains, then connect the white socket of the battery cable to
the power supply (see Figure 24 on page 16).
Check that all indicators turn on in turn momentarily and turn
off again.
Only the power on indicator should be lit afterwards.
Any fault indications should be investigated and corrective
actions taken before continuing with the installation
tests. “Status Indications” on page 8 provides a
comprehensive guide to the fault indications.
Power off the panel before commencing any corrective action
on the panel.
If there are detectors or manual call points showing the fire
condition reset the panel to clear the fire condition before you
re-enable the zone. Check that the following outputs are in the
correct state:
• Auxillary Output (30V)
• Fire Relay (C/NC)
• Fault Relay (C/NO)
• Interlink Relay (C/NC)
• FRE (0V, if fitted)
• FPE (0V, if fitted)
WARNING
DO NOT FIX ANY FAULT CONDITIONS WITH THE SYSTEM
STILL POWERED UP. THIS IS PARTICULARLY IMPORTANT
WITH SHORT CIRCUIT FAULTS ON ZONES AS THE PTC
FUSE NEEDS TIME TO RECOVER IF IT HAS TRIPPED.
Zone Fire Detection Check
Repeat the following per zone:
• Place the individual zone into Zone Test mode (see
“Individual Zone Test” on page 25).
• Activate a manual call point (or a detector if there is no call
point on the zone) in that zone and then check the following:
• General fire indicator (red) is on.
• Correct zone fire indicator (red) is on.
• All fire alarm devices are sounding.
• After approximately 3 seconds the system will automatically
silence and the fire indication will clear.
• Take the zone out of Zone Test mode (see “Individual Zone
Test” on page 25).
Reset the system to clear all fire indications.
Zone Fault Detection Check
Repeat the following per zone:
• Disconnect the last detector head on the zone then check
the following
• General fault indicator (amber) is on.
• Correct zone fault/disable indicator (amber) is fast flashing
for detector removed fault.
• Fault relay has switched over to C/NC.
Connect the detector back on its base then check
the following.
• General fault indicator (amber) is off.
• Zone fault/disable indicator (amber) is off.
• Fault relay has switched back to C/NO.
