Silencing notification appliances
Pressing the Signal Silence button turns off all audible appliances.
Visible appliances or NAC circuits may or may not turn off,
depending on panel programming.
When you silence the signals:
• The Signal Silence LED lights, indicating that the notification
appliances are off
• If Genesis horn/strobe or horn-only devices are used on NACs
programmed for Genesis operation, Signal Silence silences the
horns and strobes based on system programming
Note:
NACs activated by devices programmed as waterflow cannot
be silenced until the activated devices are restored to normal via a
panel reset. After the waterflow device events restore, the Signal
Silence button or the auto signal silence timer can silence the NACs
if there are other events causing the NACs to activate.
To silence notification appliances:
1. Press the Signal Silence button.

When the auto signal silence timer is programmed
When an event activates the notification appliances, the 5- to 30-
minute auto signal silence timer is activated. The time duration is set
in system programming. The notification appliances are activated
for the time period programmed. When the timer expires, any NACs
that are programmed as silenceable are deactivated, and the Signal
Silenced LED is illuminated.
If another event takes place that activates the previously silenced
notification appliances, the Signal Silenced LED turns off. At any time,
you can deactivate silenceable NACs by pressing Signal Silence.
WARNING:
The notification
appliances should not be
silenced until the building is
fully evacuated and the cause
of the alarm has been
determined.
