Whether you have a large house, small house, basement or attic, there may be areas in your home where you cannot hear the doorbell when it rings. In order to not miss any visitors, many homeowners add a second doorbell chime in rooms they spend a considerable amount of time, such as the basement laundry room or home office. This project is easy and should only take a couple of hours to complete.
Locate and turn off the breaker that supplies electrical power to the doorbell. Remove the cover off the existing chimes. Find the wires leading to the chimes and determine if there are two wires or three wires. When you purchase your bell wire, you will need to get wire with the same number of strands as the wire connected to the chimes.
Run the bell wire from the existing chime to the desired location of the second chime. This may require running the wire through the attic, basement or crawl space. Leave 8 inches of the bell wire at both ends and cut off any extra wire.
Affix the second chime to the wall by following the steps in the owner's manual. If the bell wire is coming through a wall, it is a good idea to hide the wire by installing the chimes directly over the hole.
At the first set of chimes, strip about 3/4 of an inch of the vinyl coating off each strand of the bell wire. Most bell wire has a red wire and a white wire. Attach the red strand of the bell wire to the connection screw on the chimes marked "Trans" by loosening the screw and wrapping the metal part of the wire around the screw. This wire connects directly to the transformer. Tighten the screw and ensure that the existing wire and the new wire are secure. Repeat the process for the remaining strand or strands of bell wire.
Strip 3/4 of an inch of vinyl coating off each strand of the bell wire to be connected to the new set of chimes. Connect the bell wire, using the same process in the previous step. Attach the red strand of the bell wire to the connection screw on the chimes marked "Trans" by loosening the screw and wrapping the metal part of the wire around the screw. Tighten the screw and ensure that the existing wire and the new wire are secure. Connect the remaining strand or strands.
Double-check that all new connections are secure. Install the chime covers. Reset your electrical breaker and press the doorbell button.
Many Chimes are shipped with cardboard or Styrofoam packing material. Remove this material before installation. If the new chime is barely audible, you will need to upgrade your doorbell's transformer. If you have any issues with wiring, consider upgrading to a wireless doorbell system.
Always turn off the power when working with electricity.
