Remote Synchronization Output Installation
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 85.
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 NFW2-100 to a compatible sync input of a power supply such as the FCPS-
24S6/8. 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 32). A 4.7 kW ELR resistor must be
connected to the end of the wiring at the remote power supply.
