INSTALLATION INFORMATION

General
Installation of this product must be carried out using the
information given in this leaflet by a qualified electrician.

BEFORE INSTALLATION ENSURE THE ELECTRICAL
SUPPLY IS ISOLATED.

Installation of this product must be carried out using the methods
and equipment specified in BS5839 Pt1 and EN54.

Consult the supplier if the equipment is to be installed in an
environment where the ambient temperature regularly exceeds
30 ºC (86 ºF)

Mounting location considerations

The fire alarm control panel should be mounted near to a
permanent, low fire risk, Entry / Exit, for easy access by the
Emergency Services. The panel should not be mounted in direct
sunlight, or in a place where the ambient temperature is above
30

o

C (86oF)

Mains must not be capable of being accidentally disconnected
and the isolating switch should clearly state :

FIRE ALARM - DO NOT SWITCH OFF

Anti static precautions should be taken when installing the panel

1 MOUNTING INSTRUCTIONS

1.1 In order to minimise the installation time, it is strongly
recommended, that the following procedure is followed.

1.2 Remove plastic fascia by removing the two screws from
the top plastic cover.

1.3 Disconnect the two secondary transformer wires from the
terminals marked ‘AC~’ on the PCB. These are located on
the right-hand side of the fire panel.

1.4 Remove the two screws that hold the bottom plastic cover
in place, then lift away from fire panel housing. Store cover
assembly in a safe place to prevent damage during initial
installation.
Note:

DO NOT REMOVE THE PCB FROM THE

PLASTIC MOULDING.

1.5 Using the back box as a Drill template, mark through fixing
positions, prepare the fixing holes, and fit onto wall using
an appropriate mounting system.
Ensure the back box is not contaminated with drilling
debris, e.g. brick dust, as this can adversely affect the
electronic circuitry.

1.6 Prepare cable entries via the 20mm knockouts provided

in the top and rear of back box using appropriate glanding
system.

1.7 Remove any debris from the back box.

2 CONNECTING THE MAINS & BATTERY

2.1 Connect mains wiring to terminal block in the back box as
marked. Note: AN EARTH CONNECTION MUST BE
MADE TO THE TERMINAL BLOCK AS MARKED.

2.2 With the mains supply isolated, replace the lower plastic
cover assembly containing the PCB. Ensure the battery
wires are routed to the top left-hand side of the back box
and the transformer secondary wires are routed towards
the right hand side. The PCB locating holes should
engage on the metal mounting tabs shown in
figure 2.

2.3 Reconnect the transformer secondary wires to the PCB
terminals marked ‘AC’.
Note: Polarisation of this connection is unimportant

2.4 Fit and tighten the two securing screws that hold the PCB
moulding in place. Ensure that the moulding has properly
engaged at the bottom of the metal back box. Do not over
tighten two retaining screws.

2.5 Fit battery into left-hand side of the back box and connect
battery using leads supplied. Ensure correct polarity is
always observed.

The panel is now active and will indicate a ‘POWER
FAULT’ and “GENERAL FAULT” until the mains supply
is re-instated, and the panel ‘RESET’.

2.6 Instate the mains supply, enter access code then press
the ‘RESET’ button.

2.7 Check panel is operating normally. The panel should only
show the green “POWER ON” indicator.

2.8 You have now proved that the panel is free of faults.

DETECTOR ZONE CONNECTION

This fire alarm control panel is supplied with End Of Line
Resistor/s for the zone circuit/s. This is for use with just
manual call points (Break Glass) units, however if removable
smoke/heat detectors are used the End Of Line Resistor/s
must be replaced with Active End Of Line Device/s (ZF19).
Please note these units are polarised.

3.1 DISCONNECT MAINS SUPPLY & BATTERY.

3.2 Connect the zone wiring, one zone at a time, transferring

either the End Of Line Resistor or Active End Of Line
Device (ZF19), if removable smoke/heat detectors are
being employed. The ZF19 devices are polarised and
should be connected with Red/Orange wire to the +ve
and Black to the –ve. See Figure 3 & 6 for typical
application.

3.3 Repeat the above procedure until all the required circuits
are connected.

3.4 Connect the sounder wiring one circuit at a time,
transferring the end of line resistor to the last sounder on
that circuit.

3.5 Repeat the above procedure until all the required sounder
circuits are connected.

3.6 ReInstate the mains supply, enter access code then press
the ‘RESET’ button.

3.7 Refit plastic fascia. Do not over tighten two retaining

screws.

GENERAL DESCRIPTION

Options included that are covered by EN54

Test Condition (10.0)
Fire Alarm Devices (7.8)

Ancillary functions provided but not required by EN54

Repeater

Accessories:

The panel is designed for use with CHLORIDE BARDIC ZF range
of fire accessories.

TECHNICAL SPECIFICATIONS

Power Supply requirements

230Vac +10 - 15% 50Hz
Maximum Power consumption 50VA
Fuse rating - T125mA

The mains supply should be carefully wired using flat twin and
earth of not less than 1mm

2

between the mains connector block
and an externally mounted secure switched fused spur outlet with
contact separation of at least 3mm. The switched spur unit should
be fused with a 2A fuse.

Battery

24 Hour standby 1 x 12 V 2.6 Ah (minimum)
Fuse rating - F1.6A

Weight

4.2 Kg (including 2.6 Ah battery & carton) approx.

Detection Circuits

No more than 30 devices of any type per zone.
20 smoke or heat detectors maximum per zone.
30 Call Points maximum per zone.

Alarm Sounder Circuits

300mA total through 2 circuits.
Nominal Voltage 25.3V (+2.7V / -1V)
Fuse rating - F315mA

Auxiliary 24V Supply

This is specifically not for fire protection devices.

Fuse Rating 1A
Note, the Auxiliary relay is configured as a fault relay, as standard
(EN54 requirement), however the relay can be configured as an
auxiliary fire relay, by moving a jumper link from the fault position
to the fire position on the back of the PCB.

AUXILIARY REL AY

123

FAULT NC C NO

FIRE NO C NC

The N/C and N/O contacts change position, when the jumper
is moved to the fire position.

Class Change

Activated by using volt free N/O contacts between the -ve of AUX
24V output and the CLASS CHANGE output. See Figure 5 for
typical application.

Cabling

Unless otherwise recommended, and taking into account voltage
drop, not less than 1mm

2

is recommended.
Sounder circuits should use cable that is fire proof.
All cabling should be earthed to the metal back box via the cable
gland.
Conductors carrying fire alarm power signals should be separated
from conductors used for carrying other systems.

OPERATING INSTRUCTIONS

Access to “SUPERVISOR MODE” for panel operation:-

To operate this fire alarm control panel, it is necessary to gain
access to the “Supervisor Mode”, to do this enter the four digit
security password code, on the yellow push buttons. This security
code should have been given to the responsible person on
system hand over.
After entering the correct code the “Supervisor Mode” LED will
illuminate.

The panel will time out of “Supervisor Mode” if the ‘RESET’
button is pressed or 20 seconds have elapsed since the last
button was pressed.

The following functions can all be employed in the
“Supervisor Mode”.

•

‘SOUNDERS ON/OFF’

If the sounders are silent, because either the panel is in alarm
and the sounders have been “Silenced”, or if there is no
alarm, the sounders will be activated by pressing this button.
If the sounders are on, and they are to be switched off, then
press the ‘SOUNDERS ON/OFF’ push button to silence the
alarm.

•

‘RESET’

This will cause all faults and fires conditions to be cancelled,
if a fault still exists then it will re-appear within 10 seconds of
this reset.

•

‘MUTE PANEL’

To silence the panel’s internal buzzer press ‘MUTE PANEL’
push button. The panel will continue to beep at a reduced rate
until the condition causing the buzzer to sound is rectified or
reset.

•

‘LAMP TEST’

Hold down ‘SELECT / LAMP TEST’ push button for a
minimum of two seconds. Release once the test is complete.
