GD 375 is a passive glass break detector glued on to the glass surface. Together with interface IU 300 it forms a Grade 2 security system according to EN 50131-2-7-2 to detect an attack against float glass through smashing with blunt force or cutting or drilling with diamond tools. Application areas are shop-windows, glass sliding doors, standard windows and other vulnerable glass surfaces in public areas and private homes.

It is equipped with a piezoelectric sensor that provides an electrical signal when the glass is attacked. The signal is digitized and then processed in an electric circuit, which increases the current in the loop. With a first-rate detector algorithm, the detector has exceptionally high immunity to interference signals that cause false alarms.

Its circular design guarantees correct positioning.

The GD 375 is glued to the glass pane and each detector is supplied with a stencil to mark the mounting location, a glue applicator and cable clamps for quick and easy installation.
