2GIG GB1-345 Glass Break Detector, 15' (4.6m) Range (GB1)

Protect vulnerable glass entry points with the 2GIG GB1-345 glass break detector — a compact, professional-grade sensor designed for reliable intrusion detection in residential and light-commercial environments. The GB1-345 combines dual-stage acoustic sensing and a dual-shatter recognition algorithm to detect both impact and glass break events while reducing false alarms from everyday noise. With up to 15 ft (4.6 m) of detection range and full 360° horizontal coverage, a single detector can monitor multiple windows or a large glass area, simplifying installation and lowering costs.

This 345 MHz wireless glass break sensor is fully supervised and includes a tamper switch for continuous system health reporting, plus onboard test LEDs and a long-life CR123A battery to streamline setup and maintenance. ETL listed for UL 464 glass break detection, the GB1-345 integrates easily with 2GIG and Honeywell 5800-series panels for flexible security system design. Ideal for alarm installers, security integrators, and facilities managers looking to strengthen perimeter security and monitoring. Add the GB1-345 to your security package today to improve surveillance and intrusion protection around windows and glass doors.
