4.13 Release Stages
Outputs programmed as Release Stage NACs indicate the two stages of a release operation:
the activation of an output programmed as a Releasing Circuit will cause the programmed
indicating NAC output to turn on steady
upon completion of the release, the programmed indicating NAC output will pulse at a 20
pulse-per-minute rate
4.14 Special System Timers
4.14.1 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.

4.14.2 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 AHJ.

4.14.3 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.

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.

4.14.4 Soak Timers
Two Soak Timers allow the user to program a time between 10 and 30 minutes for each water
releasing circuit to remain active. Soak Timer 1 is used for Releasing Solenoid Circuit 1 and Soak
Timer 2 is used for Releasing Solenoid Circuit 2. Following an alarm condition in which the
releasing circuit is activated, the water release will stop when the corresponding Soak Timer
reaches zero.

4.14.5 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.

device. This feature requires the approval of the local AHJ.
4.15 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
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
3
specification document).
