The programmer can select the notification appliance output coding by pressing the number
corresponding to the desired output. The coding selections are:
• Steady - a continuous output with no coding
• March Time - 120 ppm (pulse-per-minute) output
• California - 10 seconds on and 5 seconds off
• Temporal - ½ second on, ½ second off, ½ second on, ½ second off, ½ second on, 1½ second
off
• Cross-Zone:
1st zone of a cross-zoned group in alarm causes programmed NAC output to pulse 1
second on and 1 second off
2nd zone of a cross-zoned group in alarm causes programmed NAC output to pulse ½
second on and ½ second off - Note: if more than three zones are cross-zoned, the
programmed NAC output will continue to pulse ½ second on and ½ second off for each
subsequent zone in alarm, until the final zone in the cross-zoned group goes into alarm
All zones of a cross-zoned group in alarm causes the output programmed as a Releasing
Circuit to perform a release and the programmed NAC output to turn on steady
• 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.
3.5.3.6.1 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.
Notes:
1. The NAC1 output can be used to synchronize notification appliances connected to external
panels such as remote power supplies.
2. For Dual Hazard applications, NAC circuits are not synchronized.
3.5.3.6.1.1 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
