CRF.300(A)
Relay Module
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.
LiteSpeedTM 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. The
net effect is response speed greater than five times that of
other designs.
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-92000DLS(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. 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.
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.
