Special System Timers Operating Instructions
4.13 Special System Timers
4.13.1 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 AHJ.
4.13.2 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 AHJ.
4.13.3 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 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.
4.13.4 Pre-Discharge Delay Timers
The Pre-Discharge Delay Timers can be set to a value between 00 and 60 seconds. Upon activation
of an alarm, the agent release will be delayed by the amount of time programmed into the Pre-Dis-
charge Delay Timers.
4.13.5 Discharge Timers
The Discharge Timers can be set to Always On or a value of between 01 and 20 minutes. Following
activation of a releasing circuit, the agent will continue to release either continuously until the panel
is reset (Always On) or until the Discharge Timers count down to 0.
4.13.6 Waterflow Delay 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 AHJ.
4.14 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 walk-
test 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 3 specification document).
