4. If an Acknowledge switch is pressed, the NACs currently in 1st stage activation 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 has no
effect on the NACs unless the alarm point’s zones are directly mapped to one of the NACs. In
this case it follows the procedure outlined in step 2.
6. If another alarm point is activated and the countdown timer has stopped counting due to the
Acknowledge switch being pressed, the countdown timer restarts and the NACs respond as
outlined in step 2. NACs already in 2nd stage activation are not affected.
7. Any control modules assigned to special Zone 99 are activated either by direct mapping of an
input device programmed to Zone 99 or if the timer counts down to zero.
8. Control modules programmed to the same zone as the activated input device are activated
without delay.
Synchronized NAC Operation
Synchronization is a panel feature that controls the activation of notification appliances in such a way
that all devices 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.
Note When a Notification Appliance Circuit with a mix of audible and visual devices is
programmed for silenceable and the synchronization feature is selected, only the
audible devices are turned off if the Silence key is pressed. The visual devices (strobes
and other devices) continue to operate.
