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 activat-
ing strobes which must be synchronized to avoid random activation and a potential hazard to indi-
viduals. Devices connected directly to the control panel’s NACs can be synchronized as described
in “Type” on page 96.
Notification appliances connected to FCPS NAC power supplies require synchronization with the
FACP’s devices. This can be accomplished by connecting the Remote Synchronization Output
from TB2 of the MS-9200UDLS to the sync input of the FCPS-24FS6/8 Power Supply. The
24 VDC 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 (refer to “UL Power-limited
Wiring Requirements” on page 36). A 4.7 K
 ELR resistor must be connected to the end of the
wiring at the remote power supply.
