Heath Zenith SL-6157-D Wireless Plug-In Door Chime Extender, White
Heath Zenith's chime extender allows you to add doorbell coverage to any room in your house, provided that you have an existing wireless doorbell. It works by "listening" for the chime of your original doorbell; when it goes off, the transmitter sends out a radio signal that activates the chime unit. The chime unit plugs in to a standard outlet and features three programmable tunes and a volume control. And installation is easy-no extra wiring is required. Note that you will need to purchase three AAA batteries for the transmitter.--Josh DettweilerWhat's in the BoxPlug-in doorbell chime, extension transmitter, hardware pack
