Surface Sound Alarm Detector "Irbis" for Detecting Glass Breakage in Enclosed Spaces

Designed for detection of glass breaking (glass breaking attempt) in the protected space of the closed room by the method of acoustic signal analysis. Designed to detect the destruction of the following types of glass: conventional and protected by a polymer film thickness from 2.5 to 8 mm, reinforced thickness up to 6 mm, patterned thickness from 4 to 8 mm, multilayer construction thickness from 6 to 8 mm, tempered thickness from 4 to 8 mm. The minimum glass area is not less than 0.1 m2 (with the length of each side not less than 0.3 m).

The detector provides: self-test function when switching on and restoring the housing; anti-masking function; discrete adjustment of sensitivity by means of code tamper presses.
