4.16  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.  
NAC synchronization can only be supported properly by the Remote Power Supply Sync Terminal, 
which follows NAC 1 programming.
Important:  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 
will be turned off if the Silence key is pressed.  The visual devices (strobes, etc.) will continue to 
operate.
4.17  Coded Operation
The NAC circuits resident on the control panel main circuit board can be programmed for coded 
operation.  The available pulse rates which can be programmed for coded operation are as follows:
• Continuous: 
Steady output with no pulsing
• March Time: 
Pulses at 120 ppm (pulses per minute)
• Temporal Code: 
Pulses at ½ second On, ½ second Off, ½ second On, ½
second Off, ½ second On, 1½ second Off
• California Code: 
10 seconds On, 5 seconds Off
• Two-Stage
Pulses at 20 ppm (pulses per minute) for 5 minutes and
then changes to on steady
4.18  Presignal
Presignal option programs an initiating device to delay the activation of NACs and/or control 
modules while allowing visual verification by a person.  Once a detector or monitor module 
triggers an alarm, the onboard piezo sounds immediately, but the NACs are not activated for a user 
programmed time duration of up to three minutes. Note that the alarm relay and communicator will 
respond to the initial alarm immediately.  In addition, Zone 98 will activate.  This zone can be 
programmed to a control module which may be used to activate a sounder or indicator which the 
installer designates as a Presignal indication.  Do not assign Zone 98 to a Notification Appliance 
Circuit when using this zone to indicate a Pre-signal condition.
After the programmed delay, the NACs will activate if the source of the alarm is not cleared.  Note 
that if a second alarm occurs during the programmed time delay, the alarm will be processed 
immediately, causing activation of the appropriate output zones.  The events which occur upon 
Presignal activation are as follows: 
onboard piezo sounds immediately
control panel LCD display will indicate a presignal event and the active point
control points programmed to Zone 98 will activate
annunciators (if enabled) will sound the local piezo, and pulse the alarm LED and zone 
LED
outputs (NACs and control modules) of associated zones will be inhibited from activating 
for a user programmed time delay of up to three minutes
second alarm occurring anytime during the time delay will cause immediate activation of 
all associated outputs
Presignal does not affect monitor modules programmed as waterflow, supervisory, process 
monitoring or remote switches.  Presignal operation requires the approval of the local Authority 
Having Jurisdiction.
