Psl 2000 Smoke Detector Wiring Diagram. This series can be utilized in many different types of applications including commercial industrial and residential. For details on how to do this see Connecting 4 Wire Smoke Detectors.
A hardwired smoke alarm installation involves wiring one of the smoke detectors closest to the voltage source to a 120 VAC breaker in the main electric panel or tapping from a 120 V electrical box wiring it using a 142 cable with a black live a white neutral and a ground wire as shown by the diagram in Figure 5. Is the least efficient diagram among the electrical wiring diagram. I want to install a wired smoke alarm at the top of my stairs.
Join the black circuit wires to the black wire lead on the smoke detector.
The latest innovation for early detection of smoke and products of combustion present in air moving through HVAC ducts in Commercial and Industrial applicati. Connect the red circuit wires to the interconnect traveler wire from the smoke detector usually marked as yellow. The extra run of 4-conductor wire gives us a return path to the panel. Connect the white circuit wires with the white wire lead on the smoke detector.
