NAC Coding
The Coding feature allows the programmer to select the type of output that the main circuit board
notification appliances will generate when activated. Pressing 2 while viewing NAC Screen #1
will cause the following displays to appear:
The programmer can select the notification appliance output 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
• Two Stage 3 Minutes or 5 Minutes - refer to “Two Stage Operation” on page 68 for a
description of this feature
• Synchronized output for System Sensor, Wheelock, Gentex, Faraday or Amseco - Refer to
“Synchronized NAC Operation” on page 68 for additional information
Selection of one of the above options will cause the control panel to store the information in mem-
ory and return the display to NAC Screen #1, which will display the new coding choice.
 Two Stage Operation
Two Stage operation consists of the following:
• 1st stage output - 20 ppm (pulse-per-minute) coding
• 2nd stage output - Temporal coding as described above
• Acknowledge button functions as the automatic alarm signal cancel button
If Two Stage operation is programmed as the Coding option, the following sequence of events will
occur during an alarm.
1. The on-board NACs will activate with a 1st stage output upon activation of any alarm.
2. If, after the programmed time of 3 or 5 minutes, the Acknowledge switch has not been pressed,
all NACs presently in 1st stage activation will go to 2nd stage activation.
3. If an Acknowledge switch has been pressed, the Alarm LED will turn from flashing to steady.
Any NACs currently in 1st stage activation will remain in 1st stage. Pressing the Acknowl-
edge switch does not affect NACs already in 2nd stage activation.
4. If another alarm point is activated and the countdown timer is counting, the alarm point will
have no effect on the NACs.
5. If another alarm point is activated and the countdown timer has stopped counting due to the
Acknowledge switch being pressed, the countdown timer will restart and the NACs will
respond as outlined in step 1. NACs already in 2nd stage activation will not be affected.
