GLASSBREAK SENSOR

Dimensions93mm(h) x 24mm(w) x 25mm(d)Dimensions74mm(h) x 48mm(w) x 18.5mm(d) VIBRO is an intelligent, microprocessor-controlled shock sensorsuitable for a variety of internal applications. The unit is easy to install, featuring a unique ‘Learn Mode’ function, which automatically sets the sensitivity by ‘learning’ the level andnumber of impacts required to generate an alarm. Multiple impacts can be overridden using the ‘Gross Attack’ feature, which enables VIBRO to create an alarm from a single impact. The unit has a wide dynamic range allowing it to be calibrated tosuit quiet or noisy environments and a non-volatile memory retains all the programmed settings should the supply voltage be removed and subsequently restored. The GX-252T is a microprocessor-based glassbreak detectorutilising 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 continuefor a fixed time period, 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 to 7.6m.
