The 2GIG GB1-345 wireless glass break detector delivers professional-grade intrusion detection with dual-stage acoustic sensors that recognize both the initial impact (thud) and the glass shatter. It provides up to 15 ft (4.6 m) of coverage at a full 360° horizontal angle, communicates over 345 MHz, and is fully supervised and tamper-protected for reliable alarm reporting. Two onboard test LEDs simplify on-site sensitivity checks, while power is provided by a CR123A 3 V lithium battery for long-life performance. ETL listed for UL 464 glass break detection, this ceiling- or wall-mountable detector is ideal for residential and light commercial installations, offering robust protection against forced entry through windows or glass doors.
