20 minutes when the battery test automatically runs. Additional fault information is
also available on the PSU PC Board that has individual LEDs for the following
conditions MAINS FAIL, OVERLOAD, BATTERY FAULT, BATTERY LOAD FAIL,
CHARGER FAIL and AC INPUT HIGH/LOW.
NB:
Please note that the LED colour has changed from RED to YELLOW.
Panel Functions:
All panel functions may be executed by pressing the relevant button/s on the
membrane keypad. Confirmation of each function/s activation is displayed on the facia
and is audible on Lamp Test.
Reset Function:
The reset button must be used to reset a Fire Alarm or Fault condition. The panel will
not reset if the condition persists. Faults must be rectified and no smoke should be
present in detector heads, similarly all call points must have their operating elements
installed correctly.
Silence Function:
The silence button should be used to silence the internal buzzer or the external
warning devices.
Evacuate Function:
By pressing this button both bell circuits (external warning devices) will be energised
with an intermittent voltage of one second on and one second off until the reset or
silence button is pressed.
Lamp Test
Function:
All LEDs on the facia must illuminate and the internal buzzer must sound when this
button is pressed. If an LED does not illuminate or the buzzer sound, the panel must
be repaired.
Zone Isolate
Function:
A faulty zone may be isolated from the system by pressing and holding the isolate
button together with the zone number button. The isolated zones LED will illuminate.
To de-isolate the procedure should be repeated. Once a zone has been isolated no
Fire Alarm or Fault conditions will be indicated for that zone. No common outputs,
extinguishant area outputs or sounder circuits can be activated by an isolated zone.
NB:
An important feature of this panel is the auto isolate feature on short circuit
fault. If a zone is in short circuit Fault condition for longer than 1 minute, the
panel will automatically isolate that zone. This feature will prevent unnecessary
power consumption and eliminate false fire alarms.
Walk-test Function:
One person can test all detectors connected to the panel and/or external sounders
with the walk-test function. To activate, the Walk-Test button must be pressed and
held together with a zone number button.
That zone’s fault LED will illuminate together
with maintenance LED on the system status window. If a zone is in walk-test mode,
any Alarm condition from that zone will cause the external sounders to operate 3
times. Walk-test can be reset by pressing the reset button. If there is no activity on the
keypad or detector circuit for more than 25 minutes, the panel will automatically reset.
NB:
Common Fire, Zone Relay, Extinguishant Output and FBC will not operate when
the zone is in walk-test mode.
Manual / Automatic
Key switch:
Key switch is used to switch between Manual and Automatic mode. When Manual
mode is selected, the Manual LED indications will illuminate and only the Manual
Extinguishant Release Call Point will be able to activate a Discharge Condition. When
Automatic mode is selected, the Automatic LEDs will illuminate and a double-knock
Fire condition between Zone 1 and 2, as well as the Manual Extinguishant Release
Call Point will be able to activate a Discharge condition.
Release Initiated:
LED will illuminate when both Zone 1 and Zone 2 are in a Fire Alarm condition. This is
a monitored circuit that produces a 24 V DC output and can be utilised as a second
stage alarm indication. If there is a fault on the circuit, the Fault LED will illuminate.
Extinguishant
Released:
LED will illuminate once countdown timer has lapsed upon which the Discharge
Output will be activated and the extinguishant will be released. This is a monitored
circuit that produces a 24 V DC output to the detonator or solenoid. If there is a fault
on the circuit, the Fault LED will illuminate.
