 Synchronized NAC Operation
Synchronization is a panel feature that controls the activation of notification appliances in such a
way that all horns and strobes 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 3.0 amps. Refer to
the manufacturer’s documentation 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:
 System Sensor: 46 Strobes
 Wheelock: 50 Strobes
 Gentex: 39 Strobes
 Faraday: 33 Strobes
 Amseco: 34 Strobes
Refer to the Device Compatibility Document for a list of compatible devices.
3.5.4 Cross Input Zones
An application may require that two or more input zones become active at the same time before a
particular releasing output activates. This is referred to as cross-zoning. For example, an installer
may want four particular zones to become active at the same time before a releasing circuit is
activated. By using the Cross Input Zone feature, the programmer can designate the input zones
that must become active and the output circuits that will be affected. Refer to “Circuit Mapping
and Cross-Zoning” on page 112 for additional information.
The Cross Input Zone option allows the user to view and program the groups of input zones that
will be used to activate one of the releasing output circuits. Pressing 1 while viewing Programming
Screen #2 will display a screen similar to the following:
NOTES:
1. The NAC1 output can be used to synchronize notification appliances connected to external
panels such as remote power supplies (wire NAC1 to the power supply sync input).
2. For Dual Hazard applications, NAC circuits are not synchronized across hazard areas.
