Operating Instructions

4.20 Special System Timers

4.20.1 Silence Inhibit Timer
This option, if selected, prevents the Alarm Silence key 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.
4.20.2 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.
4.20.3 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 the trouble is not cleared within 24 hours, the piezo will resound, indicating that the
trouble condition still exists.
4.20.4 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.
4.20.5 Alarm Verification (None or One Minute)
If alarm verification is selected, an addressable smoke detector's alarm is ignored for a retard time
of 13 seconds and the detector's alarm condition is automatically reset. There will be no alarm
indication at the FACP during the Retard period. A confirmation period of 60 seconds follows,
during which a subsequent alarm from the same detector will cause the panel to immediately
activate the appropriate outputs and indicate the alarm condition at the FACP. If a different detector
alarms any time during the first detector's verification period, the panel will immediately activate
all appropriate outputs and indicate the alarm condition at the FACP. If no additional detector
alarms occur within 73 seconds of the first alarm (13 second retard plus 60 second confirmation),
the timer resets and the panel is ready to verify any new detector alarms which may occur. The
following is a graphic representation of Alarm Verification.
