4.17 Special System Timers
4.17.1 Silence Inhibit Timer
This option, if selected, prevents the
Alarm Silenced
and
Reset
keys from functioning for 60
seconds following an alarm. A new alarm during the initial 60 second period will not cause the
timer to restart with a new 60 seconds.
Silence Inhibit operation requires the approval of the local
Authority Having Jurisdiction.
4.17.2 Autosilence Timer
If Autosilence is selected, the notification appliances, programmed as silenceable, will
automatically be silenced after a programmable duration of from 5 to 30 minutes. Pressing the
Drill
key will restart the timer.
Autosilence operation requires the approval of the local Authority
Having Jurisdiction.
4.17.3 Trouble Reminder
If selected, this feature causes a reminding ‘beep’ every 15 seconds during an alarm (after the
Alarm Silence
key is pressed) and every two minutes during a trouble condition (after the
Acknowledge/Step
or
Alarm Silence
key is pressed). The ‘beeps’ from the onboard piezo sounder
will occur until the alarm or fault is cleared.
Note that if Trouble Reminder feature is not selected and the trouble is not cleared within 24 hours,
the piezo will resound, indicating that the trouble condition still exists.
4.17.4 Waterflow Retard Timer
If selected, this option will delay the activation of a waterflow type alarm for a programmable time
duration from 1 to 90 seconds. This delay is in addition to any time delay inherent in the waterflow
device.
This feature requires the approval of the local Authority Having Jurisdiction.
