Control Modules CMF-300-6 Installation
6.3.2 Wiring a Style Z NAC (Four-Wire) with Addressable Control
Modules
A supervised and power-limited NFPA Style Z (Class A) NAC using a CMF-300 module. Polarized
alarm notification appliances are shown connected to the module in a four-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 Z circuit.
• Do not loop wiring under the screw terminals of any notification appliance. To maintain
supervision, break the wire run at each device.
6.4 CMF-300-6 Installation
6.4.1 Cabinet Installation
This type of module is contained in either a BB-2 or BB-6 cabinet. The BB-2 can accommodate up
to 2 modules and the BB-6, which requires the CH-6 chassis, can accommodate up to 6 modules.
See the Installation Instructions provided with module for proper installation into cabinet.
6.4.2 Setting an SLC address for an CMF-300-6 Module
In “Style Y” operation each CMF-300-6 module can be set to one of 154 base addresses (01-154).
The remaining module points are automatically assigned to the next five higher SLC addresses. For
example, if the base address is set to 28, the next five module points will be addressed to 29, 30, 31,
32 and 33.
NOTE: Refer to the Device Compatibility Document for compatible notification appliances and
relays.
