Crystal Break Detectors

DEM-1282 Model: AD 800

Acoustic Glass Break Detector Grade 2.




AD 800 is a new generation of acoustic glass break detector meets the requirements for grade 2 of the new standard EN 50131-2-7-2:2013, corresponding to the recommendations for high security installations.

The detector is designed to acoustically detect intrusion attempts into a protected area by breakage of a window or glass pane. The detector is based on the latest microprocessor technology and has a number of advanced algorithms connected to the acoustics of the room (Digital Room Compensation, DRC). Thanks to these algorithms, the detector can distinguish a glass breakage signal from other interferences and boasts high immunity to false alarms.

Intended for indoor installation, the device can be mounted either on a ceiling or wall, opposite to the protected glass. The detection range spans 165°, which means that one detector can monitor multiple windows in a room. The detector is able to detect standard, tempered and laminated glass.

Note: Avoid mounting the detector in the corner of a room, close to louver windows and ventilation grills.
