Magnasphere’s MSS series is a concealed style security sensor that can be easily installed in almost any application. The MSS series installs in fail safe mode (open loop). This is the same configuration required for other life safety devices such as smoke and fire alarms.
The MSS series is virtually unbreakable and highly resistant to outsider magnet defeat and permanent contact welding (caused by lightning and/or power surges).
