Special System Timers
control panel LCD display will indicate a presignal event and the active point
control points programmed to Zone 097 will activate
outputs (NACs and control modules) of associated zones will be inhibited from activating for a factory set duration of 15
seconds
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 deacti-
vated. While PAS is inhibited, signaling devices will immediately 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.
4.22 Special System Timers
4.22.1 Silence Inhibit Timer
This option, if selected, prevents the Alarm Silence key from functioning for 5 minutes following an alarm. A new alarm during the ini-
tial 5 minute period will not cause the timer to restart with a new 5 minutes. Silence Inhibit operation requires the approval of the local
Authority Having Jurisdiction.
4.22.2 Autosilence Timer
If Autosilence is selected, the notification appliances, programmed as silenceable, will automatically be silenced after a programmable
duration of 5 to 30 minutes. Pressing the Drill key will restart the timer. Autosilence operation requires the approval of the local Author-
ity Having Jurisdiction.
4.22.3 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.
4.22.4 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.
4.22.5 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.
