2.6 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 88.

Notification appliances connected to remote power sources may require synchronization with the FACP’s devices. This can be accomplished by connecting the Remote Synchronization Output from TB2 of the MS-9200UDLS to a compatible sync input of a power supply such as the FCPS-24FS6/8. The 24 VDC, 40 mA signal from TB2 follows, that is mimics, the signal on NAC1. This allows the devices connected to the power supply to be synchronized with the devices connected to NAC1 on the FACP.

The Remote Synchronization Output is power-limited and supervised and requires a ferrite bead (refer to "UL Power-limited Wiring Requirements" on page 35). A 4.7 kΩ ELR resistor must be connected to the end of the wiring at the remote power supply.
