3.1.2 Fire Alarm with Alert Annunciation
When an alert annunciation alarm is activated, the acknowledgement time starts. The fire
alarm indicator will start to flash (0.4/0.4 s) and the button “
Acknowledge
” will be available
to use.
When the alarms have been acknowledged, the investigation time starts. The fire alarm
indicator will stop flashing and the button “
Reset”
will be available to reset the alert
annunciation alarm.
If the alarms are not reset within the investigation time, the Fire brigade alerted symbol will
be activated. If two or more alarms exist in the system, the button “
Alarms queued
” will be
shown, and the user can scroll amongst the alarms.
When all fire alarms are reset (from 5054), the display unit will return to normal operation (if
the fire alarm is cleared).
