Getting Rid of the Wired System
If you currently have a wired doorbell system, you may want to disable it. Although the electrical current running through to the doorbell may not be that strong, it should be shut off to prevent any mishaps from occurring. Removing the old doorbell is a simple task that can be accomplished with a screwdriver. Taking the screwdriver, unscrew the old wired system. Using electrical tape, cover the ends of the wires individually and then wrap the wires together. According to The Doorbell .net, it is best to wrap the wires together this way to prevent any fire hazards or to enable use of a wired doorbell in the future. After pushing the wires back through the open hole, you are ready to install the wireless doorbell.
Installing the Wireless Doorbell
The wireless doorbell should fit over the new open hole. You can mount the doorbell either using a screwdriver or double-sided tape. Wireless door bells come with chime units which work as receivers that can be placed anywhere within range of the doorbell.
Some chime units may run on batteries but can also be plugged in if you wish to avoid changing them every so often. You will need to find a good spot to place the unit in your house. For the best placement, pick a spot that will enable you to hear the doorbell from any area of the house. You may also be able to pick and choose what kind of chime you would wish to hear when someone is at your door.
You can test the doorbell by having someone push the button outside while you are inside the home, or vice versa.
Some wireless doorbell systems have more than 32 chimes, while others come with security systems that have either an intercom system that will allow you to talk to the person outside or even video to help you see who is at your door. These options are more expensive then the basic wireless system.
