Special System Timers Operating Instructions
Note that the PAS BYPASS monitor type code, when activated, will inhibit the PAS capability until
the PAS BYPASS monitor is deactivated. While PAS is inhibited, signaling devices will immedi-
ately place the control panel into alarm. This feature may be employed by wiring a normally open
device, such as a switch, to a monitor module which has been programmed for PAS BYPASS.
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 automati-
cally 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 Acknowl-
edge/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 enabling/disabling the Trouble Reminder feature has no effect on Trouble Resound.
When an existing trouble in the system is silenced, if the trouble condition is not cleared before
midnight, 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 23 seconds and the detector's alarm condition is automatically reset. There will be no alarm indi-
cation 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 appropri-
