2.5 Remote Synchronization Output
Synchronization is a 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 to individuals. Devices connected directly to the control panel's NACs can be synchronized as described in "Type" on page 79.
Notification appliances connected to FCPS NAC power supplies require synchronization with the FACP's devices. This can be accom-
plished by connecting the Remote Synchronization Output from TB8 of the ES-200X to the sync input of the FCPS-24FS6/8 Power Supply.
The 24 VDC signal from TB8 follows, that is mimics, the signal on NAC1. This allows the devices connected to the power supply to be syn-
chronized with the devices connected to NAC1 on the FACP.
The Remote Synchronization Output is power-limited and supervised (refer to "UL Power-limited Wiring Requirements" on page 29) and
can be wired in Class B or Class A. A 4.7 KΩ ELR resistor must be connected to the end of the wiring at the remote power supply for Class
B wiring. Supervision of the remote synchronization is automatically enabled when the remote sync output is enabled. Supervision will be
disabled if the output is disabled. For more information on enabling the remote sync output, refer to page 106.
