General
The CMF-300(A) Addressable Control Module provides
Fire•Lite intelligent control panels a circuit for Notification
Appliances (horns, strobes, etc.). Addressability allows the
CMF-300(A) to be activated through panel programming, on a
select (zone or area of coverage) 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. 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 powered directly by two-wire SLC loop.
The CMF-300(A) module requires power (for horns,
strobes, etc.).
• Integral LED “blinks” green each time a communication is
received from the control panel and turns on steady red
when activated.
• High noise immunity (EMF/RFI).
• The CMF-300(A) may be used to switch 24-volt NAC
power.
• Wide viewing angle of LED.
• SEMS screws with clamping plates for wiring ease.
• Direct-dial entry of address: 01– 159 for MS-9600 series
panels, 01 – 99 on MS-9200UDLS and MS-9050UD.
Applications
The CMF-300(A) is used to switch 24 VDC audible/visual
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 CMF-300(A) is configured for a single Class B (Style Y)
or Class A (Style Z) Notification Appliance Circuit.
Operation
Each CMF-300(A) uses one of the module 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. The CMF-300(A) supervises Class B (Style
Y) or Class A (Style Z) notification or control circuits.
Upon code command from the panel, the CMF-300(A) will dis-
connect the supervision and connect the external power sup-
ply in the proper polarity across the load device. The
disconnection of the supervision provides a positive indication
to the panel that the control relay actually turned ON. The
external power supply is always relay-isolated from the com-
munication loop so that a trouble condition on the external
power supply will never interfere with the rest of the system.
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 module and a sen-
sor address.
