Serene Innovations Door Knock/Chime Transmitter

The wireless Doorbell/Door Knock and Door Chime Sensor is part of the CentralAlert Notification System by Serene Innovations. Place the Door Knock/Door Chime Sensor next to your existing chimebox or intercom system and when someone activates either device the Sensor will transmit a signal to the CA360 Transmitter and respective receivers. Alternatively you could put the Door Knock/Door Chime sensor on the door itself and if someone knocks, the sensor will detect the vibrations and transmit a signal to the CA360 system.

Central Alert receiver is required to be notified.
