How to Install a BRK Smoke Detector

Trip the circuit breaker in the electrical panel that disconnects the electric power to the room with the light fixture to be replaced with the BRK smoke detector. If a fuse is used instead of a circuit breaker, remove this fuse.

Place a ladder against the wall where the light fixture is located. Remove the light bulbs from the fixture. Remove the screws surrounding the light fixture with a Phillips screwdriver. Pull the fixture off the wall. Unscrew the screw tabs holding the wires from the fixture and from the electrical junction box inside the wall together. Separate the wires from each other. Place the light fixture aside.

Hold the BRK smoke detector in one hand with the grill facing down. Twist the bracket off the top of the detector with the other hand -- a counterclockwise motion is needed .

Pull the wires from the electrical junction box through the hole in the center of the bracket. Place the bracket against the electrical junction box. Screw metal screws through the holes in both sides of the bracket and into the screw holes in the electrical junction box using a Phillips screwdriver.

Twist the exposed end of the black wire from the back of the BRK smoke detector around the exposed end of the black wire from the electrical junction box. Twist the exposed end of the white wire from the back of the BRK smoke detector around the exposed end of the white wire from the electrical junction box. Screw a screw tab onto each pair of twisted wires. Continue screwing the screw tab on until resistance is felt. Tuck the orange wire attached to the back of the detector into the electrical junction box.

Place the back of the BRK smoke detector against the bracket. Twist the detector onto the bracket with a clockwise motion. Restore power at the electrical panel.
