Honeywell Fire-Lite Alarms MRP-2001 Instruction Manual page 59

Master Programming Level
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 59 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 dual 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.
