Product Description

The GBD Plus sensor operates based on the product of two criteria occurring at the time of breaking glass: a high-frequency criterion from broken glass and a low-frequency criterion from a strong impact on the glass surface. GBD Plus will only trigger an alarm if both of these criteria are met. Thus, it will not respond to acoustic signals that may only resemble the sound of breaking glass, such as a bell, the clink of keys, music, etc.

In order to accurately adapt the sensor to the conditions of a particular room, two potentiometers are used to allow separate adjustment of sensitivity for both detected frequencies. These allow the sensor to be adjusted for both a large, acoustic room (e.g., a noisy office) and a quiet room.

Main features:
  • Dual-frequency analysis: impact + glass breakage
  • AND/OR function - possibility to disable analysis of one of the tracks
  • Unique analysis of acoustic interference
  • Alarm memory (LED)
  • Sensitivity adjustment
  • New housing design
  • On- or under-plaster mounting (optional)
  • Wide operating range
