Glass Breakage Alarm

A great and affordable solution to protect windows, doors, cabinets, etc. The alarm is activated by the sound generated from anyone breaking or knocking glass. Once triggered, the alarm generates a 100db blast for approximately 30 seconds, at which points it stops and resets itself. The alarm included a 12 volt battery and strong adhesive tape, in case you want to permanently attach it. Very affordable protection. 2” × 2½” x 1”
