Silencing NACs manually
Pressing the Signal Silence button turns off all silenceable NACs unless
activated by a waterflow device or waterflow zone. Depending on system
programming, some audible or visible notification appliances may not turn off
when the Signal Silence button is pressed. If a signal silence inhibit was
programmed, then pressing the Signal Silence button will not work until the reset
inhibit timer expires. See“What is in-suite signal silence?” on page 34.
When you silence the signals:
• The Signal Silence LED lights to indicate 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. Pressing Signal Silence a second time while the
panel is in an alarm state causes the signals to turn on again.
Silencing NACs automatically
Two options let you silence NACs automatically: Auto Signal Silence and Suite
Signal Silence (in-suite signal silence). Both work by starting a timer when an
event activates the NACs. The NACs are allowed to sound until the timer expires,
after which they are automatically silenced.
The Auto Signal Silence option
Auto Signal Silence can be enabled when programming the panel. It affects all
silenceable NACs connected to the panel. The elapsed time can be set for 5 to
30 minutes. See “Activating and restoring sensor bypass” on page 168.
The Suite Signal Silence option
The Suite Signal Silence option enables or disables in-suite signal silence for the
selected correlation group. This option affects only silenceable NACs associated
with the correlation groups. For more information on this programming this
option, see “Programming in-suite signal silence” on page 92.
NACs that cannot be silenced
NACs configured as latched outputs cannot be silenced. This includes any
device configured as:
• Continuous Non-Silenceable Latched (Cont NS Latch)
• Supervised Outputs Latched (SupOut Latch)
