Master Programming Level
Programming
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 #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 Acknowledge 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.
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.
