Fire-Lite CRF-300 Addressable Relay Module
CRF-300 addressable relay modules provide a dry-contact output
for activating a variety of auxiliary devices, such as fans, door holders,
dampers, control equipment, etc. Addressability allows the dry contact to be
activated through panel programming, on a select basis. Each relay module uses
one of the addresses on a SLC loop. It responds to regular polls from the control
panel and reports its type and status, including the open/normal/short status of its
Notification Appliance Circuit (NAC). The LED blinks with each poll received. On command, it activates its internal relay.
