If you have no doorbell or your current hard-wired bell is not working properly, an alternative is to install one that is wireless. A wireless doorbell system will contain one or more battery-operated transmitters and as many receivers, or chimes, as you would like to have. Some receivers require a battery and others plug into a wall outlet. The system utilises a radio frequency to transmit a signal from the transmitter to the receiver. Installing a wireless doorbell system that will work on three separate floors is straightforward and not very complex, even in a multilevel home.
Purchase the wireless doorbell kit that will meet your needs. If you want transmitters at multiple doors, choose a kit that contains the correct number of buttons. For installations requiring more than one receiver, check the packaging for the maximum distance you can locate them from the transmitter. If you are installing receivers on three separate levels in your home, wall thickness, floor thickness and electronic interference might decrease the distance you will be able to place the receivers from the transmitter. Purchase all batteries that will be necessary for proper operation of the system. The battery requirements will be listed on the side of the package.
Remove the old doorbell switch, if one is present. Turn off the power to the doorbell at the main circuit panel by flipping off the appropriate breaker or removing the correct fuse. Remove the button, using a screwdriver. Disconnect the wires from the switch. Wrap each wire with electrical tape. These wires must be wrapped separately so the exposed ends of the wires will not come in contact with each other. Push the wires into the hole where the old switch was removed. Once you tuck the wires into the wall, it is safe to turn the power back on to install your wireless doorbell on three separate floors.
Install batteries in the transmitters. Attach the transmitter outside the door. The doorbell kit will provide the screws necessary for this. Some systems will utilise double-sided tape to attach the doorbell buttons. If you are placing transmitters at more than one entrance, many systems will allow you to program each of them with a different chime pattern, which will allow the homeowner to know which door to answer. This is usually accomplished by adjusting a button or switch inside the transmitter.
Choose a location for the receiver chimes. If you need to plug them into a wall receptacle, your choices for location will be more limited. If the receivers are battery operated, place batteries in the units and install the receivers at the desired locations. Mark the location where the holes need to be drilled. Using the drill bit size recommended in the instructions enclosed with the kit, drill the holes and attach the receivers to the wall at each site on the three floors, using the screws provided.
