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:

Switch 6

 

 

 

No Synchronization

OFF

OFF

System Sensor Synchronization

ON

OFF

Gentex Synchronization

OFF

ON

Wheelock 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.

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:

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:

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.
