The CA-360 is an all-in-one notification system for your home. It alerts you to all the daily sounds in your home such as alarm clock, door knocking, phone ringing, alarm sound from your audio alarms, warnings from your motion detectors and storm warning from your NOAA radio and more*. It uses a bright built-in flasher, selectable loud yet pleasant audible sound and a powerful bed shaker. There is no installation needed for the CA-360, and all operations are wireless.
You can easily attach the Door Knocking Sensor (Model CA-DX, sold separately) to this hanger and hang it on your door knob to detect the knocking on your door. The CA-DX sensor sends a wireless signal to trigger the CA-360 to alert you that someone is at the door. Ideal for both home and hotel stay applications.
