Silent Call introduces the next generation of alerting systems for people who are deaf or hard of hearing. The all new Signature Series features new transmitter types, increased range (up to 2000 feet), elegant design, greater flexibility and upgradability, on the 418 MHz transmission frequency. Awareness, safety and home security are all available in this system that configures to individuals’ needs.

This transmitter has two magnetic contact bars. When the door or window is opened, the bars lose magnetic contact, triggering the transmitter and will send a signal to the Signature Series Sidekick II or Watch Receiver (#6930 or #6932).
