Master Programming Level
Coding (only for NACs not programmed as Sync Strobe Type)
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 #2
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 - refer to "Two Stage Operation" on page 87 for a description
Selection of one of the above options will cause the control panel to store the information in
memory and return the display to NAC Screen #2, 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
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 which are programmed to General Alarm Zone 0 will activate with a 1st
stage output upon 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 will go directly to 2nd stage coding output. All other NACs not directly
mapped to the activated alarm point's zone but assigned to Zone 0 will activate with a 1st stage
output
3.
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
4.
If an Acknowledge switch has been pressed, any NACs currently in 1st stage activation will
remain in 1st stage. Pressing the Acknowledge switch does not affect NACs already in 2nd
stage activation
5.
If another alarm point is activated and the countdown timer is counting, the alarm point will
have no effect on the NACs unless the alarm point's zones are directly mapped to one of the
NACs, in which case it will follow the procedure outlined in step 2
