Honeywell 5853 Wireless Glass Break Detector

Most security products come with some pretty dodgy instructions, but the ones included with the glass break protector were pretty good. Installed in my partially exposed basement and enrolled in the Ademco Vista 20P in 10 minutes.

I have purchased two of these for areas in my house with glass panes not suitable for shock sensors that stick to the glass pane itself (eg sliding glass doors, opening windows, etc). I installed them as Zone Type 3, Perimeter Sensor, in my Ademco system.

I purchased a FG701 that simulates a "flex" event followed by sound of breaking glass. The flex event, which was never well-defined anywhere, is basically an object hitting glass prior to a break. Combined, this sensor looks for a flex (thud of something hitting glass), followed by a breaking glass sound. This helps eliminate false-positives. I tested the installation locations with the FG701, mounted the units, and can say they actually work. I re-confirmed it by accidentally triggering the test sound while I had the alarm armed in stay mode :P The alarm instantly went off indicating the faulted zone. Further, I brought my tester to my friend's place with an ADT system that had a similar looking sensor on his wall. Without waiting for me, he went and played with the sensor. It triggered his alarm and the monitoring company called. As a result, I'm certain these devices work quite well.

Note: if you're installing these you really should pick up a FG701. It is difficult to tell if the location of the sensor will pick up both sounds without this device. E.g. how do you know if your drapes are too heavy for the sensor to be 25' away without *really* testing it.

These glass break sensors work great and are very sensitive. I've accidentally set them off by knocking over a heavy metal cookbook holder in the kitchen, that my wife insists be kept in the middle of the counter. The sensor is about 10 feet from where the cookbook lives.
