Programming
NAC remains on steady until all zones of the cross-zoned group go into alarm
Release Circuit going into Pre-discharge or Discharge state (at any time) causes the NAC to
turn off. All other NACs will operate as programmed.
When using this coding protocol at least one other NAC must be programmed for one of the
following: Cross-Zone (see above), Release Stage Coded (see page 85), Release Stage Pre-
Discharge (see page 85), or Release Stage Discharge (see page 85).
•
Cross-Zone Discharge for Release Circuit 1 or Release Circuit 2:
1st zone of cross-zoned group in alarm causes programmed NAC output to turn on steady
NAC remains on steady when all zones of the cross-zoned group go into alarm and during
Pre-discharge
Release Circuit going into Discharge state (at any time) causes the NAC to turn off. All
other NACs will operate as programmed.
When using this coding protocol at least one other NAC must be programmed for one of the
following: Cross-Zone (see above), Release Stage Coded (see page 85), Release Stage Pre-
Discharge (see page 85), or Release Stage Discharge (see page 85).

Synchronized output for System Sensor, Wheelock, Gentex, Faraday or Amseco - Refer to
"Synchronized NAC Operation" on page 62 for additional information.
Selection of one of the above options will cause the control panel to store the information in
memory and return the display to Output Screen #1, which will display the new coding choice.
NOTE: If the Output Circuit has been programmed as a Releasing Circuit, the Coding Option will
not be available and the display will indicate N/A next to it.
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.
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.
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.
