An NAC can be used to signal the stages of a release operation. This screen allows the programmer
to select the NAC output that will indicate the release stages for Release Circuit 1 or Release
Circuit 2. For a description of this feature, refer to “Release Stages” on page 93.
Silence
Pressing 1 while viewing Output Screen #2 will cause the following screen to be displayed:
Pressing 1 while viewing the Silenceable Screen #1 will program the selected Output as a
silenceable circuit. This will allow the Output to be silenced by pressing the Alarm Silence key or
by the Auto Silence feature.
Pressing 2 while viewing the Silenceable Screen #1 will program the selected Output as a
nonsilenceable circuit. This will prevent the selected main circuit board Output from being
silenced by pressing the Alarm Silence key or by the Auto Silence feature.
Pressing 3 while viewing the Silenceable Screen #1 will program the selected Output for Stage
Silenceable. This option is used for Release Stage NACs or cross-zone coding NACs. These
NACs will be non-silenceable until its associated Release Circuit has finished discharging, after
which the NAC will become silenceable.
Pressing 1 while viewing the Silenceable Screen #2 will program the selected Output as a SYNC
MUTE (synchronized mute) circuit. Refer to “Synchronized NAC Operation” on page 63 for a
description of synchronization.
Important: When an Output Circuit with a mix of audible and visual devices is programmed for
Sync Mute, only the audible devices will be turned off if the Silence key is pressed or if the
Autosilence feature is enabled. The visual devices (strobes, etc.) will continue to operate.
