Coding Selection
The Coding feature allows you to specify the type of output the main circuit board NAC generates,
when activated. The various 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.
• Two Stage 3 Minutes or 5 Minutes - For more information about Two Stage Operation, see
Two Stage Operation.
• Synchronized output for System Sensor, Wheelock, Gentex, Faraday, or Amseco. For more
information about Synchronized NAC Operation, see Synchronized NAC Operation.
Two Stage Operation
Two Stage operation consists of the following:
• 1st stage output - 20 ppm (pulse-per-minute) coding
• 2nd stage output - Temporal coding
If Two Stage operation is programmed as the Coding option, the following sequence of events
occurs during an alarm.
1. The on-board NACs are activated with a 1st stage output on activation of any alarm point.
2. If the activated alarm point is directly mapped to a zone which is programmed to an on-board
NAC, that NAC goes directly to 2nd stage coding output. All other NACs not directly
mapped to the activated alarm point’s zone but assigned to Zone 0, activate with a 1st stage
output.
3. If, after the programmed time of 3 or 5 minutes, the Acknowledge switch is not pressed, all
NACs presently in 1st stage activation go to the 2nd stage activation.
