Doorbell’s can provide a more pleasant notification that someone is at the front door, as opposed to loud rapping or a loud buzzer. Basic doorbell installation is even easier when a new doorbell and chimes are taking the place of an older model that provides a less than soothing sound to announce visitors. Fortunately, the actual steps can be managed with relative ease and are perfectly safe as long as proper precautions are taken.
Disable electricity. Make sure that circuits that supply electricity to the old doorbell and chime are turned off. To make sure, use a circuit tester to check for the presence of any power in the device.
Attach the new doorbell switch to the wall. Use the screws provided to secure the plate into position, and then slide the cover over the device until it snaps into position.
Secure the new chimes into position. Place the new chimes over the hole and use the screws provided to attach the device to the wall or ceiling. Once the chime plate is secured, fit the cover over the device and gently push until it snaps into place.
