Firelite CRF-300 Relay Control Module

The Firelite CRF-300 Addressable Relay Module provides the system with a dry-contact output for activating a variety of auxiliary devices, such as fans, door holders, dampers, control equipment, etc. Addressability allows dry contacts to activate through panel programming, on a select basis.

The Firelite CRF-300 may be programmed to operate dry contacts for door holders, Air Handling Unit shutdown, etc., as well as to reset four-wire smoke detector power.

Each CRF-300 uses one of the addresses on a SLC loop. Additionally, 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. Furthermore, on command, it activates its internal relay

Rotary switches set a unique address for each module. The built-in TYPE CODE (not settable) will identify the module to the control panel, so as to differentiate between a control module and a relay module.
