The GB-502 PG2 is a wireless, two-way glass break detector, designed to detect the breaking of glass that is mounted in a frame.
The acoustic sensor of the GB-502 PG2 is omni-directional and thus has a coverage area of 360 °. The detection range is measured from the sensor to the part of the glass which is furthest removed.
The minimum distance between sensor and glass should be 1.5 meters. If the detector is mounted on the opposite or on the same wall, the maximum range is 7.6 meters for standard glass, safety glass, laminated glass and wire glass.
If the detector is mounted on the ceiling, the maximum range is 7.6 meters for standard glass, safety glass, laminated glass and wire glass.
For special burglar-resistant glass, it is recommended that the detector does not extend more than 3.65 meters from the glass.
