Fire-Lite CRF-300 2-Form Relays, Built-in, Addressable Relay Module

Description

The CRF-300(A) Addressable Relay Module provides the system with a dry-contact output for activating a variety of auxiliary devices. such devices include fans, door holders, dampers, control equipment, etc. Address-ability allows dry contact activation through panel programming, on a select basis.

LiteSpeed is a communication protocol developed by Fire-Lite Engineering that greatly enhances the speed of communication between analog intelligent devices. Intelligent devices communicate in a grouped fashion. If one of the devices within the group has new information, the panel CPU stops the group poll and concentrates on single points. The net effect is response speed greater than five times that of other designs.

Addressable Relay Module Features

•  Built-in type identification automatically identifies these devices to the control panel.
•  Internal circuitry and relay powered directly by two-wire SLC loop.
•  Integral LED “blinks” green each time a communication is received from the control panel and turns on in steady red when activated.
•  High noise immunity (EMF/RFI).
•  Wide viewing angle of LED.
•  SEMS screws with clamping plates for wiring ease.
•  Direct-dial entry of address: 01– 159 for MS-9600(A) series panels, 01 – 99 on MS-9200UDLS(A) and MS-9050UD(A).

Applications

Program the CRF-300(A) to operate dry contacts for door holders, Air Handling Unit shutdown, etc.  Also can operate to reset four-wire smoke detector power.
