FRONT PANEL CONTROLS
3.1.1 Access/Inhibit
The ACCESS/INHIBIT keyswitch provides the means of inhibiting the four control push-buttons
and the keypad, i.e. the normal functions of these four switches and the keypad are only available
when the keyswitch is in the ACCESS position. From the STATUS NORMAL condition, i.e.
INHIBIT, selection of the ACCESS position will place the panel in ACCESS mode the display
in fig 1.1.1.
TUE 15 MAR 21:45
When the keyswitch is turned back to the INHIBIT position, all keypad functions are disabled
and the display will return to the STATUS NORMAL mode, thus terminating any menu option
selected.
Any menu function will also be terminated if any of the four main control switches are operated.
3.1.2 Silence Alarms
The SILENCE ALARMS push-button is used to terminate any audible alarms.
If the internal buzzer is activated by any fault conditions, then operating the SILENCE ALARMS
push-button terminates its operation.
In the event of a fire-alarm, the internal buzzer is activated in a continuous mode, the two
sounder outputs are energised, and the auxiliary contacts are also activated. In this condition the
SILENCE ALARMS push-button de-activates the sounder outputs and changes the internal
sounder to a pulse mode. The auxiliary contacts are maintained until the fire condition is reset.
The SILENCE ALARMS must be operated before the SYSTEM RESET.
The LED visual indicators, i.e. FIRE LEDs and the zone LEDs, change from the flashing to the
steady state when the SILENCE ALARMS is pressed. A subsequent alarm will cause the FIRE
bar and the new zone LED to flash, but the original zone LED will remain steady.
