8 RELAY, STROBE, HORN AND AUDIBLE SETTINGS AND
CONFIGURATIONS
The FCS has four on board relays that can be configured to be enabled or disabled, operate in
a failsafe or not failsafe manner, and be configured with ON delays and/or OFF delays. Relays
can be overridden for a forced, timed action such as during maintenance or testing. The
relays are rated 5 amps @ 240 VAC each and can be used to control remote alarms, strobes,
exhaust fan starters, make up air fan contactors, or signaling other equipment like fire panels
or alarm systems, etc.
NOTE:
The door mounted buzzer and the terminal connected horn and/or strobe devices
are considered to be relays by the FCS. However, instead of using relay numbers, the words
AUDIBLE, STROBE and HORN are displayed in the relay fields of the various configuration
screens.
If more relays are required, the FCS can be connected to the RLY-4 Remote Relay which
offers four additional SPDT dry contact relays plus two horn/strobe 24 VDC drives. or
similarly, the RLY-8 Remote Relay that offers eight additional SPDT dry contact relays plus
four horn/strobe 24 VDC drives. The remote relay devices communicate with the FCS using
Modbus® communications protocol.
