Glassbreak Sensor Installation Guide


Glassbreak Sensors are programmed to listen for the specific frequency of windows breaking. They're even sensitive enough to know the difference between a plate breaking, and a window breaking.

Inside the Glassbreak Sensor is a small microphone that is calibrated to react to the sound of the glass being struck and then breaking. Pane glass has a certain sound frequency when smashed, which the sensor hears and then trips the alarm. The sensor is listening for the initial “thump” of the glass being struck, which in effect “wakes” it up, and the sound of the glass breaking micro-seconds later trips the alarm.

Installing the Glassbreak Sensor

We recommend placing the Glassbreak Sensor within 20 feet of the window you want to protect, facing the glass. If you have heavy curtains within your home, you may want to adjust the Glassbreak Sensor to be within 5-10 feet of that window.

The Glassbreak Sensor can be placed on a flat surface, or wall mounted using the adhesive strip on the back of the device. If you are wall mounting the Glassbreak Sensor, ensure that the wall is clean and dry prior to adhering it to the surface. Press and hold the sensor for 30 seconds to ensure it secures in place.

The Glassbreak Sensor is only compatible with single and double-paned glass. It is not intended to be used with any laminated or anti-smash glass.
