 Synchronized NAC Operation
Synchronization is a panel feature that controls the activation of notification appliances in such a
way that all devices will turn on and off at exactly the same time. This is particularly critical when
activating strobes which must be synchronized to avoid random activation and a potential hazard or
confusion. The FACP can be programmed to operate with a variety of manufacturer’s devices.
Maximum Number of Strobes for Synchronization
The maximum current draw for a Notification Appliance Circuit cannot exceed 2.5 amps for mod-
els with the FLPS-3 power supply or 3.0 amps for models with the FLPS-7 power supply (refer to
the AC Power section under“Specifications” on page 15). Refer to the manufacturer’s documenta-
tion supplied with the Strobes to determine the maximum current draw for each strobe and ensure
that the circuit maximum is not exceeded.
To ensure proper strobe and circuit operation, there is also a limit to the number of strobes that can
be attached to each circuit. Following is a list of the strobes that have been tested with this FACP
and the maximum number that can be connected to each NAC. Make sure that the NAC maximum
current is not exceeded:
Silence
Pressing 1 while viewing NAC Screen #2 will cause the following screen to be displayed:
Pressing 1 while viewing the Silenceable Screen will program the selected NAC as a silenceable
circuit. This will allow the NAC to be silenced by pressing the Alarm Silence key or by the Auto
Silence feature.
Pressing 2 while viewing the Silenceable Screen will program the selected NAC as a nonsilence-
able circuit. This will prevent the selected main circuit board NAC from being silenced by pressing
the Alarm Silence key or by the Auto Silence feature.
Pressing 3 while viewing the Silenceable Screen will program the selected NAC as a synchronized
mute circuit. Refer to “Synchronized NAC Operation” on page 68 for a description of synchroni-
zation.
Important: When a Notification Appliance Circuit with a mix of audible and visual devices is pro-
grammed 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.
