A supervised and power-limited NFPA Style Z (Class A) Notification Appliance Circuit (NAC)
using the M300CJ module. Polarized alarm notification appliances are shown connected to the
module in a four-wire configuration.
1. See “Power Considerations” on page 53 for information on supervising 24 VDC power.
2. Each module can control 2 amps of resistive load (on electronic devices) or 1 amp of inductive
load (on mechanical bells and horns).
3. A power supervision relay is required only on the last module of the power run.
(IFC-3030 only: If using one of the IFC-3030’s FlashScan type IDs that provide built-in power
supervision, no relay is required.)
4. Do not T-Tap or branch a Style Z circuit.
5. Do not loop wiring under the screw terminals of any notification appliance. To maintain
supervision, break the wire run at each device.
6. Refer to the Device Compatibility Document for compatible notification appliances and relays.
