The GX-252T is a microprocessor-based glassbreak detector utilizing dual frequency analysis to detect the common sounds of shattering glass and acoustical shock when a window is broken. The sensor only activates when specific frequency patterns continue fo a fixed time, making it highly immune to false alarms. The GX-252T protects 3mm (1/8") plate glass and 6mm (1/4") plate tempered and laminated glass at a range of up to7.6m.
