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.
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.
Maximum Number of Strobes for Synchronization
The maximum current draw for a Notification Appliance Circuit cannot exceed 2.5 amps for mod-
els with the FLPS-3 power supply or 3.0 amps for models with the FLPS-7 power supply (refer to
the AC Power section under"Specifications" on page 15). Refer to the manufacturer's documenta-
tion 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:
