Prevent Missed Calls with a Telephone Ring Detector

Factory assembled telephone ringer detector VM144 connects to your phone line (with your telephone). When the phone rings, a powerful LED flashes to provide a visual alert. Connect a 12VDC power adapter to enable the built in output relay. Choose between continuous or toggle relay operation to switch power to external devices such as remotely located lamps, buzzers, sirens. Great for incoming call alerts in remote locations or noisy environments, or as a visual indicator for the hearing impaired.

Also available as a kit you can build. See telephone ring detector electronic kit K8086.
