Serene CentralAlert Wireless Notification System
The Serene CentralAlert Wireless Notification System (Model CA360) is an all-in-one notification system for your home. It alerts you to all the daily sounds in your home such as the alarm clock, door knocks, telephone rings and alarm sounds from your audio alarms, as well as providing warnings from your motion detectors and storm warnings from your NOAA radio. (Accessories that are sold separately are required for some of these functions.) It uses a bright built-in flasher, a selectable loud, yet pleasant audible sound and a powerful bed shaker to alert you. No installation is needed, and all operations are wireless.
