STI STI-3350 Wireless Doorbell Chime with Receiver

The STI 3350 Wireless Button is an easy-to-install musical wireless doorbell chime with no electrical wiring and no expensive through-the-wall drilling. Installation is as easy as mounting the button on the exterior of the door and plugging the receiver unit into any indoor electrical outlet in range. The unit has a 500-foot operating range. To extend coverage to more rooms purchase additional receiver units that can be plugged into any room within 500-ft of the transmitter. You can distinguish between front and back doors by adding more transmitters and programming a different tune on each. There are ten sounds that can be selected with the push of a button on each transmitter.
