Installation
2.4.3 Relays - Programmable
The SFP-5UD and SFP-10UD control panels provide a factory default programmed alarm relay, fail-safe trouble relay and supervisory
relay. Each relay can be programmed to activate for other conditions (refer to "Relays" on page 67). Each Form-C relay is rated for 2
amps @ 30VDC (resistive) and 0.5 amps @ 30 VAC (resistive).
Note that relay connections must be power-limited.
Note: Relay contacts are shown with
power applied to the panel and no active
troubles, alarms or supervisories.
The Trouble Relay is a fail-safe relay
which will transfer on any trouble or total
power failure.
2.4.4 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 NAC can be synchronized as described in "Synchro-
nized NAC Operation" on page 65.
Notification appliances connected to remote power sources may require synchronization with the FACP's devices. For the SFP-5UD,
this can be accomplished by connecting the Remote Synchronization Output from TB2 of the FACP 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 NAC 1 (Out 1). This
allows the devices connected to the power supply to be synchronized with the devices connected to Out 1 on the FACP.
For the SFP-5UDC, SFP-10UD(C)/E, the Remote Sync Output is not required. Synchronization for remote power supplies is provided
directly from NAC1 (Out 1). Note that NAC 1 (Out 1) must be programmed for sync operation when used for this purpose.
The Remote Synchronization Output is power-limited and supervised and requires a 4.7KΩ ELR resistor at the remote power supply end
of the wiring.
