Special System Timers

4.20 Special System Timers

4.20.1 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 Authority Having Jurisdiction.

4.20.2 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.

4.20.3 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 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.

4.20.4 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.
