Imagine a quiet office after hours, a retail storefront with large display windows, or a home with sliding glass doors. The ABUS Security-Center FU7301W glass breakage detector listens for the specific high-frequency sound of breaking glass and triggers an alarm, providing an extra layer of security for vulnerable glazed areas. It is a potential-free detector, meaning its relay output can be integrated into almost any alarm system or used to trigger other devices. The detector comes with an adhesive pad for quick, screw-free mounting on window frames or walls.

Good to know

The detector is designed for indoor use only (IP30). It detects the sound of breaking glass within a radius of approximately 2.5 meters, so position it centrally relative to the glass area. The potential-free relay output can be configured as normally open (NO) or normally closed (NC) to suit your system's requirements. The 4-wire cable provides flexibility for connection to power and alarm circuits.
