A: If you can find a way to extend the wiring to the basement, the transformer that powers your existing doorbell should have no problem handling a second chime. However, there's a better solution. Several companies make wireless doorbell extenders for situations where running additional wiring is impractical.
A doorbell extender consists of a small adapter that mounts inside your existing chime box and a plug-in chime unit. To install, all you need is a screwdriver and about 10 minutes. Here's how it works: The adapter contains a tiny radio transmitter. When someone rings the bell, the adapter sends a signal to the remote chime, causing it to ring.
Doorbell extenders are great for a garage, workshop or patio. Some models can transmit up to 150 feet, far enough to reach a detached building. Chime units are sold separately so you can expand your system as needed.
Wireless chime systems can solve a variety of doorbell woes. For example, it's usually easier to convert to wireless than to attempt repairs on a broken doorbell wire. If your transformer still works, the simplest approach is to install a replacement electromechanical chime that's been modified to work with a wireless door button. Swapping components is straightforward.
What if the builder neglected to install a doorbell at the "friends and neighbors" entrance? Unfortunately, no one offers a kit to add a wireless button to an existing chime box. However, a stand-alone door chime system solves this problem with no fuss. Depending on the model, the chime unit either plugs into an electrical outlet or operates on batteries. Prices start at under $20.
Until recently, most wireless chimes were made from white impact plastic. Now you can choose from a variety of styles and colors - from solid wood to polished brass. Some models simulate the familiar Westminster chimes or play a brief musical ditty. Other models feature real chime tubes for those who don't care for an electronic ding-dong.
Like conventional doorbells, most wireless chimes can accommodate one or two door buttons. Other convenience features include a low battery indicator and a volume control. One model even has a built-in intercom so you can query your visitors before opening the door.
At least two companies make portable chimes that are small enough to fit in a shirt pocket. This allows you to keep tabs on the front door while working in the yard or soaking up some rays. Since the button unit is also portable, it could even serve as a bedside call-button or local-area pager. There's nothing that says it must be mounted on a door!
"Doorbells" are also available for individuals with hearing impairments. With one system, an existing door button connects to a small power line carrier transmitter. The plug-in receiver unit can be used to flash a lamp or activate a vibrator. Another system has a portable receiver with built-in vibrator and indicator light. It's designed to be worn on a belt or carried in a pocket.
