Process To Disconnect A Hardwired Smoke Detector

Just like any other wired device, you should shut off the circuit breaker so that your detector remains power free. This is because you may be electrocuted and even get injured unawares. If you want to check whether the wires carry any current, you should use a non-contact voltage tester in order to make these verifications.

All you need to do is to turn the hardwired smoke detector in a counterclockwise direction so as to unscrew it from the mounting plate. By doing this, you will leave the wires exposed and thus, you can carry on with your testing. Once you test and confirm that there is no current flowing through the wires, time is ripe for you to remove the old smoke detector from the wires.

You just need to pull the connector and then separate the wire from the detector. Depending on the model you have installed, the connector may be different. However, most of them usually come with a quick-connect feature that allows you to connect the wires seamlessly.

After that, put the detector aside and then unscrew the two screws that hold the mounting bracket to the wall or ceiling. Check how the mounting bracket has been positioned so that you can have an easy time in case you have to install a new mount next time.

Once you remove the mounting bracket, you can leave the screws in place in case you may want to paint the area and so forth. Also, this helps you know where you had positioned the hardwired smoke detector, in case you may want to install it again. In addition, ensure that you tuck in the wires safely into the hole next to the detector to avoid unwanted interference.
