Acoustic Glass Break Detector Alarmtech AD800-AM — glass-break sensor, model AD800-AM

The Alarmtech AD800-AM acoustic glass-break detector is designed to detect the specific sound signatures of breaking glass and signal an alarm event to a connected intruder alarm system. Intended for perimeter protection, this glass-break sensor analyses acoustic patterns produced by impact and shattering, providing an additional layer of security for windows and glazed areas in residential and commercial settings. The compact detector mounts near protected glazing and interfaces with standard alarm control panels to report detections.

Advantages

The device recognises both impact and shatter acoustic patterns, reducing false alarms from unrelated noises while maintaining sensitivity to actual glass break events. Its acoustic sensing approach allows coverage of multiple panes from a single unit and simplifies installation compared with contact-based sensors. The detector integrates with common security systems and is suitable for retrofitting into existing alarm installations.

Suitable for

• Monitoring windows and glass doors in homes
• Protecting shopfronts, display windows and glazed façades
• Supplementing motion sensors and door contacts in office environments
• Use in entrances, conservatories and skylight areas where glass is exposed

Key specifications

• Detection method: acoustic analysis of impact and shattering sounds
• Coverage: designed to monitor multiple panes within a typical room from one mounting point
• Installation: wall- or frame-mounted near protected glazing
• Output: alarm contact or signal compatible with standard intruder alarm control panels
• Power: driven by the alarm system supply via detector wiring (check panel compatibility)
• Operating environment: indoor use near glazing; choose mounting to avoid direct airflow or loud machinery

How to use

Mount the detector on an interior surface near the top edge of the window or glazed area facing the pane to be protected, following the manufacturer’s recommended distance and orientation. Connect the detector to the alarm control panel according to the panel wiring diagram and configure input zones as required. Test the detector after installation using a calibrated glass-break test method or approved test signals to verify sensitivity and coverage. Adjust mounting position if required to ensure reliable detection of both impact and shatter events while minimising false alarms.

Usage recommendations

Place the detector where it has a clear acoustic path to the glass but is shielded from direct sources of repetitive noise or strong airflow. Regularly test the detector during routine alarm system maintenance and keep firmware or panel settings up to date through qualified service personnel.
