3.1.3.5 Strobe Synchronization
Switches 5 and 6 are used to program the Synchronization feature. This feature
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. The following table lists the required switch settings to
accomplish synchronization:

The factory default setting is switches 5 and 6 OFF for No Synchronization.
3.1.3.5.1 Maximum Number of Strobes for Synchronization
The total current draw for each Notification Appliance Circuit cannot exceed 2.5
amps. Refer to the manufacturer’s documentation supplied with the strobes to
determine the maximum current draw for each strobe and ensure that the circuit
maximum is not exceeded.
amps. Refer to the manufacturer’s documentation 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:

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:
System Sensor: 40 Strobes
Wheelock: 25 Strobes
Gentex: 23 Strobes
3.1.3.6 Nonsilenceable Waterflow for Combination Circuit
If SW1 switch 8 is set to the ON position to select a Combination Waterflow/
Supervisory Circuit (refer to "IDC Combination Circuit" on page 34) and SW3
switch 7 is set to the ON position to select the Nonsilenceable Waterflow for the
Combination Circuit option, the following conditions will occur:
If SW1 switch 8 is set to the ON position to select a Combination Waterflow/
Supervisory Circuit (refer to "IDC Combination Circuit" on page 34) and SW3
switch 7 is set to the ON position to select the Nonsilenceable Waterflow for the
Combination Circuit option, the following conditions will occur:
• MS-2 - NACs become nonsilenceable upon acitvation of IDC #1 (Combination
Circuit)
• MS-4 - NACs become nonsilenceable upon activation of IDC #2 (Combination
Circuit)
Notes:
1.If initial alarm activations are from IDCs other than the Combination Circuit,
the NACs will be either silenceable or nonsilenceable, depending on the
setting of SW3 switches 1 and 3 (refer to "NAC1 Nonsilenceable" on page 36
and "NAC2 Nonsilenceable (MS-4 only)" on page 36).

2.If alarm activation is from the Combination Circuit programmed for
nonsilenceable, all NACs will be nonsilenceable regardless of subsequent IDC
activations.

3.1.3.7 Spares
Switch 8 is a spare switch and has no function at this time. The switch should
therefore be left in the factory default setting of OFF.
