SYSTEM OPERATION (continued)
Silencing the alarm
Before the alarm sounders can be silenced the CONTROLS keyswitch must be set to the ON
position by inserting the key and turning it clockwise a quarter of a turn. Alternatively a code may
be entered to the keypad to enable the controls. (providing this option is set in the parameters)
With the controls enabled, press the SILENCE/RESOUND ALARMS keypad button once:-
1 The alarm sounders on the system are silenced.
2 The LCD will illuminate to indicate the current status.
3 The flashing common fire and zone LEDs change to steady.
4 The buzzer tone changes to an intermittent bleep.
5 The LCD continues to show the event information.
NOTE
: If another device is activated, the sounders are re-energised and the new event
information is displayed.
If there are multiple events on the system, the information for each event may be viewed by using
the toggle function with keypad buttons 2/8.
The ‘MORE’ LED is illuminated if there are other events. The LCD shows the total number of
events.
Resounding the alarm
If, having silenced the sounders, it is necessary to reactivate them, e.g.because there are
personnel still within the building, press the SILENCE/RESOUND ALARMS keypad button again.
Resetting the system
To restore the system to normal operation after a fire alarm it is necessary to
reset the control panel by pressing the RESET button. (Key 9 on keypad)
All the LEDs illuminate for 3 -4 seconds (lamptest function) following which
the panel reverts to its normal mode.
NOTE
:
1
It is not possible to reset the system until the alarms have been silenced.
2
The system will not reset if the cause of the alarm is still present, i.e broken glass in call
point or smoke/heat in the vicinity of a detector.
