To wire a 4-wire smoke detector, connect the detector's power terminals to the Resettable Power output (TB1 terminals 3 and 4), which provides 24 VDC filtered power (Page 9) [1].
Because this power output is nonsupervised, you must install an A77-716B power supervision relay at the end of the power run to monitor the circuit (Page 10) [1].
Connect the detector's power inputs to the FACP Resettable Power terminals (TB1-3 and TB1-4) (Page 9) [1].
Wire the detector's alarm contacts to an addressable monitor module (such as an MMF-300) to communicate with the SLC (Page 178) [1].
Install the A77-716B relay at the end of the power circuit, wiring its contacts in series with the monitor module's initiating loop (Page 10) [1].
Verify that the voltage drop from the power source to the end of the branch does not exceed 1.2 volts (Page 178) [1].
