STI 3300 Wireless Doorbell Extender with Receiver







Wireless Doorbell Extender with Receiver
Special Order


This musical wireless doorbell chime connects to your existing traditional hard wired doorbell and extends where you can hear your doorbell from. Once the unit is wired into your existing system, the included receiver can be plugged into any standard electrical outlet up to 500' (line of sight) from the existing doorbell. This allows you to hear when someone is at your front door when you are in the basement, garage or other part of the house or business, where you normally can't hear your doorbell.

You can distinguish between front and back doors by adding another transmitter. The front doorbell will play one of ten user selected melodies. The second doorbell will play a "dong" sound.
