Special System Timers
Operating Instructions
• pressing the Alarm Silence or Acknowledge/Step key will start a timer which inhibits output
activation for additional time delay of up to three minutes which is user programmable
• second alarm occurring anytime during either time delay will cause immediate activation of
all associated outputs
PAS operation requires the approval of the local Authority Having Jurisdiction.
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 and Reset keys from functioning for 60 seconds
following an alarm. A second alarm during this 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 Hav-
ing 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 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
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 acti-
vate 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
