CRF-300 DATA SHEETdf-60379:A1 • 08/04/09 — Page 1 of 2 CRF-300(A) Relay Module Addressable Devices df-60379:A1 • E-400 General The CRF-300(A) Addressable Relay Module provides the sys-tem with a dry-contact output for activating a variety of auxil- iary 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. LiteSpeed™ is a communication protocol developed by Fire•Lite Engineering that greatly enhances the speed of com- munication 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. Thenet effect is response speed greater than five times that of other designs. Features • Built-in type identification automatically identifies thesedevices to the control panel. • Internal circuitry and relay powered directly by two-wireSLC 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 The CRF-300(A) may be programmed to operate dry contacts for door holders, Air Handling Unit shutdown, etc., and to reset four-wire smoke detector power. Construction • The face plate is made of off-white heat-resistant plastic. • Controls include two rotary switches for direct-dial entry of address setting. • The CRF-300(A) is configured for a single Class B (Style Y) or Class A (Style Z) Notification Appliance Circuit. • The CRF-300(A) provides two Form-C dry contacts that switch together. Operation Each CRF-300(A) uses one of the addresses on a SLC loop. Itresponds 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. NOTE: Open/short supervision is suspended with the CRF-300. Rotary switches set a unique address for each module. The address may be set before or after mounting. The built-in TYPE CODE (not settable) will identify the module to the con- trol panel, so as to differentiate between a control module and a relay module.
