Glass Break Alarm 100dB 2 Pack

The Glass Breakage Alarm is the perfect low cost security solution for homes and businesses. This alarm’s powerful vibration sensor is triggered when glass is hit, knocked or broke by anyone. Once triggered, it sets off a loud 100dB siren alerting anyone nearby of a break-in as well as scaring off any intruders. The 100dB siren will sound off for approximately 30 seconds and then shut off and reset.
Easy installation: All you need to use to install is the included peel off adhesive and then simply mount onto the window and switch on the alarm mode.
Two units included to ensure double the protection!
