What's the difference between a glass break sensor and a window sensor?Last Updated: 11/07/2013 |

A window sensor, like the 5811BR, works in a similar way to a door sensor. It has an internal reed switch, a magnet, and a contact. The magnet and reed switch are close together when the window is closed. An opened window separates the two which triggers an alarm. A window sensor only sounds an alarm when a window is opened. But what if the window is broken? That's where the Honeywell Glassbreak Detector comes in. Glassbreak detectors are equipped with audio microphones that detect the sound frequency of broken glass. These sensors are typically mounted on the wall opposite a window, and if an intruder should break the glass, the alarm will trigger. Shock sensors work like preemptive glassbreak sensors. They can sense when window glass is vibrating at a rate consistent with someone trying to forcibly break the glass. This sensor triggers an alarm before a window is even broken, which deters an intruder even before entry, and saves you the cost of having to replace a broken window. Similar Products:
