Walktest

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.
4.17.5 Alarm Verification (None or One Minute)
If alarm verification is selected, a smoke detector activation will cause the FACP to reset the detector by removing power for 6 seconds.
Power is reapplied and a 17 second retard period begins which allows all detectors to stabilize. If no other detectors alarm, there will be
no alarm indication at the FACP during the 23 second Reset/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 zone alarms any time during the first detector's Retard & Confirmation period, the panel
will immediately activate all appropriate outputs and indicate the alarm condition at the FACP. If no additional detector alarms occur
within 83 seconds of the first alarm (23 second Reset/Retard plus 60 second Confirmation), the timer resets and the panel is ready to ver-
ify any new detector alarms which may occur.

4.18 Walktest
Walktest is a feature which allows one person to test the fire alarm system. An audible walktest will momentarily sound the Notification
Appliance Circuits in the building and store the walktest information in a file at the panel. A silent walktest will not sound the NACs but
will store the walktest information in a file which can be viewed at the panel. Disabled NAC devices will not activate during walktest. In
addition, i 3 smoke detectors will enter their own test mode causing their LEDs to flash twice every five seconds (refer to i
document).
Alarm/Shorted Condition
When in audible Walktest, the panel responds to each new alarm and activates the NACs for four seconds. It also stores each alarm in the
walktest history file which can be sent to an optional printer. The stored display will be the same as if the device actually activated except
the colon (:) in the time stamp is replaced with an asterisk (*).
Open Condition
IDCs and all main circuit board NACs are monitored for fault conditions during Walktest mode. When an open condition occurs on an
IDC, the FACP will activate all enabled NACs during an audible Walktest and remain activated until the open condition is cleared.
