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

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.
