Notes:
1) Pressing RESET/RESOUND/TEST ZONE LAMPS when in the unsilenced Fire condition (i.e. Sounder Outputs
energised) has no effect. The sounders MUST be Silenced first before Reset is active.
2) When the Alarm Sounders are silenced, the warning beeper will sound and cannot be silenced.
3) Resetting the system from the Silenced Fire state with the fire condition still existing will retrigger the alarm.
EVACUATE
Press EVACUATE. The Sounder Outputs will operate, the ZONE FIRE indicators will light and the warning beeper
will sound. Press SILENCE ALARM SOUNDERS and the Sounder Outputs will return to the normal state. The ZONE
FIRE indicators will still be lit and the warning beeper will still be active. Press RESET/RESOUND/TEST ZONE LAMPS
to return the panel to normal state.
TESTING THE SYSTEM
Check each detector and sounder on the system, and check the functions of the panel. Check all circuits for open
and short circuit faults. If continuity diodes are fitted remove each head in turn and check that call points are still
operative. When testing is complete return the keyswitch to NORMAL position.
ANCILLARY FACILITIES
(Links and internal features are shown in Fig 6 below)
ENGINEERS TEST (NON-LATCH TEST) FACILITY
This range of panels has a non-latching test
facility which allows manual call points and
smoke detectors to be tested and reset
automatically. To set this facility move the link
marked ‘PL1’ on the main PCB from the lower
to the upper position and the adjacent indicator
will light, the warning beeper will sound and
cannot be silenced. When an alarm condition is caused the alarm sounders will operate for about half a second
and will silence for three seconds before resounding. This will continue until the cause of the alarm is removed by
the smoke clearing from a detector or the call point being reset. When testing is complete, replace the link to the
lower position.
ZONE ISOLATION FACILITY
Each Detector Zone can be isolated individually by moving the links (PL2/PL4/PL5/PL6) from the lower to the upper
position. The adjacent indicator and relevant ZONE FAULT indicator will light to show that the zone is isolated. The
warning buzzer will sound and cannot be silenced. When testing is complete, replace the link to the lower position.
TO REVERT TO SHORT CIRCUIT = FIRE
This facility overrides the short circuit fault monitoring for each zone and allows the panel to be used on
installations which do not have Call Point Resistors fitted. It produces a short circuit Fire condition when activated.
To enable this facility cut the wire links (LK1/LK2/LK3/LK4) on the main PCB.
AUXILIARY EXPANSION PLUG (PL10)
This plug connector offers facilities for driving Repeater Panels, Fire and Fault relays and a "Class Change" input.
These facilities require various ancillary devices to be added to the panel (not included).
AUX 24V +VE
This output is a regulated, unmonitored, output fused at 1A (F4), available from terminal 1 in the panel’s base
connections. With link ‘PL3’ on the main PCB linked in position furthest from the F4 fuse this output is continuous.
If linked nearest to the F4 fuse then the output is present when the panel is normal but is switched off when the
relay is activated. This facility can be used to provide a fail-safe output via AUX 24V, that "switches off" when the
sounders are activated, or if power to the panel fails.
Note
: Any load provided by this output increases the quiescent drain on the panel’s supply which in turn affects
the stand-by time of the system. It is not intended to supply door release systems.
VOLTAGE FREE RELAY CONTACTS
These single pole relay outputs, available via terminals 2 (normally closed), 3 (common), and 4 (normally open) in
the panel’s base connections, change over when the sounders are activated. They must not be used to switch
Mains potentials, the contacts being rated at 30Vdc and 1.0A.
