Glass break detector Teletek GBD20 for indoor use, digital sensor, model GBD20

Teletek GBD20 is a digital glass break detector designed for indoor use. The device continuously monitors acoustic and vibrational patterns associated with glass breakage and activates an alarm output when a matched signature is detected. Built for integration with alarm systems in homes, offices and retail premises, the GBD20 focuses on reliable detection while reducing false triggers through digital signal processing.

Advantages

The GBD20 combines a sensitive microphone and vibration sensor with on-board digital processing to distinguish true glass-break events from common background noise. Its indoor-optimized detection algorithm provides consistent performance in enclosed spaces, and the unit's compact design allows discreet mounting near windows or glass doors. Low power consumption and compatibility with standard alarm panels simplify installation and upkeep.

Suitable for

• Residential windows and patio doors
• Retail shopfronts and display windows
• Office partition glass and conference room windows
• Interior glass doors and glass cabinets

Key specifications

• Detection method: combined acoustic (microphone) and vibration sensing
• Signal processing: digital pattern recognition to reduce false alarms
• Installation environment: indoor use
• Mounting: surface mount near glass elements
• Power: low-voltage DC operation compatible with standard alarm system supplies
• Output: alarm trigger compatible with wired security panels
• Form factor: compact enclosure suitable for discreet placement

How to use

Mount the detector on a stable surface near the protected glass following the recommended height and orientation in the installation manual. Connect the device to the alarm panel's power and input circuits according to the panel's wiring diagram. After powering the detector, perform a functional test using a calibrated glass-break test or an approved test method to confirm that both acoustic and vibration sensing operate correctly. Adjust placement if necessary to avoid excessive ambient noise sources or mechanical vibrations that may affect detection performance.

Usage recommendations

Place the Teletek GBD20 on the same plane as the protected glass and avoid mounting on flimsy or vibrating surfaces. Test the detector after installation and periodically as part of routine security system maintenance. Combine the GBD20 with window contacts or motion detectors for layered protection of vulnerable entry points.
