Smoke detectors are an important safety function for modern families.Once the first smoke is found, they can alert residents to the fire, allow them to put out the fire before it gets out of control, or evacuate the family if necessary.While some smoke detectors are only powered by batteries, other smoke detectors can be connected to the Circuit of the home.You can hard-After a few minutes, connect the smoke detectors in the new building with some basic hand tools.Place a ladder below the position where a new smoke detector is installed on the ceiling.Install the junction box on the ceiling pallet closest to the desired location, and the bottom edge of the junction box is 3/8 below the bottom edge of the pallet.Connect the junction box to the pallet with a pair of 1 1/2-Inch wood screw using electric drill.Run a cable with a length of 14/2 between the junction box and the circuit breaker panel.Drill a 5/8-If necessary, pass the wire through the wall through the inches hole of the roof above the breaker panel.Pull the 3 feet cable into the circuit breaker panel and then extend the other end of the wire to the junction box.Cut enough wires to make the 8 inch slip through the wire holder in the junction box.Use a tool knife to peel off the outer sheath from the cable inside the circuit breaker panel.Route the white line around the box neatly to the neutral bar, and the black line to the open 20-Amplifier circuit breaker.Trim the end of the wire to the appropriate length and then peel off the 3/4 insulation from the end of each wire.Connect the black line to the circuit breaker terminal and tighten the terminal screw.Connect the white line to the open terminal on the neutral bar and tighten the terminal screw.Tighten the wire clip in the junction box around the cable with a screwdriver.Remove the outer sheath with a tool knife.Peel 1/2 off the black and white wire tip of the cable.Connect the black wire to the black wire of the AC wire harnessPower smoke detector with wire nut.Connect two white wires in a similar way.Connect the wire into the junction box, and then pass the connector at the end of the harness through the hole in the center of the smoke detector mounting plate.Connect the plate to the junction box using two mounting screws.Slide the connector into the socket on the back of the detector and then connect the detector body to the board.After turning on the power of the circuit breaker panel, you can test the circuit and the detector.
