The Serene CentralAlert Extra Wireless Doorbell (CA-DB) is a weather resistant and easy to install doorbell that, when pushed, sends wireless signals to the CA-360 notification system to let you know that someone is at the door. This alerting system is great as an extra doorbell for your back or side doors.
Note: This item will not work on its own. It is an option for use for the CentralAlert CA-360 notification system (available for purchase separately).
