Wired Telephone & Doorbell Signalers

These are the latest in Sonic Alert's quest to develope the best combination signaler with the most features. We have added the feature of a great price! You have the choice of one of the two following hard-wired systems to notify you of both the doorbell or chime and telephone. Whether or not you have an existing doorbell/chime, either of these models will work for you (Sonic Alert is supplying a doorbell button for use in cases where there is not an existing doorbell). You can choose between a system for single room notification (DS80) or for use with additional receivers for multiple room notification (DS800).
