These door chime kits typically contain a transmitter and a receiver. The difference between these kits and the plug-in versions is that the receivers in these kits are powerd by batteries.
Don't let the fact that these are battery powered worry you. Typically, the batteries will last 12-24 months, depeding on usaage and environmental factors. Battery operation allows you to mount these chime higher in the wall, and allows the manufacturer to design a more aesthetic design that seen in most plug-in models.
As with the plug-in version, if you stay with a particular manufacturer, like Carlon, you can mix and match plug-in and battery operated receivers.
Great for large homes and businesses that need to transmit over long distances, the DC-1000 has the power you need to transmit signals over long distances and penetrate through walls that typical products cannot.
This beautiful wireless hand-carved cabinet Craftmade, comes ready to add a designer touch with a matte black finish and tea stained glass. All the "LH" models use the Carlon and Dimango chime electronics to deliver a best-in-class product.
Great stand alone door bell, or extend your existing Carlon system to a back patio, deck or garage.
