6.5 Wiring a CMF-300-6 Module

This section contains basic instructions and diagrams for wiring a Signaling Line Circuit with a
CMF-300-6 as a Notification Appliance Circuit (NAC).

For more detailed information on wiring a CMF-300-6 Control Module refer to the Installation
Instructions provided with the module. Included in these instructions are wiring diagrams concern-
ing a single power supply being shared by multiple NACs and audio NAC configurations.

6.5.1 Wiring a Style Y NAC (Two-Wire)

A supervised and power-limited NFPA Style Y (Class B) NAC with a single power supply dedi-
cated to a single NAC using a CMF-300-6 module. Polarized alarm notification appliances are
shown connected to the module in a two-wire configuration.

See “Power Considerations” on page 61 for information on monitoring 24 VDC power.

Each module can control 2 amps of resistive load (on electronic devices) or 1 amp of inductive
load (on mechanical bells and horns).

24 VDC power must be provided from a UL listed power supply for fire protection use.

A power supervision relay is required only on the last module of the power run.

Do not T-tap or branch a Style Y circuit.

Terminate the circuit across the last device using an End-of-Line Resistor 47K, 1/2-watt,
P/N SSD A2143-00 (ELR-47K in Canada).

Do not loop wiring under the screw terminals of any notification appliance. To maintain super-
vision, break the wire run at each device.

NOTE: Refer to the Device Compatibility Document for compatible notification appliances and
relays.
