A working smoke detector is a must-have in every home, but these days, simply having a battery-operated one isn’t enough. Most building codes now require there to be a smoke detector on every level of the home and it’s recommended that they not only be hardwired to a dedicated circuit, but also be interlinked so if the detector on the third floor rings, the ones on the first and second floor will ring as well.
This job does require one to work with an electrical circuit, but it isn’t an overly difficult task and one that most do-it-yourselfers can do. The greatest obstacle is usually running the feeder wire from the electrical panel to the smoke detector and the traveler wires to the remaining detectors.
