Encrypted 345 MHz Glass Break Sensor with 15ft Detection Range, 360-Degree Horizontal Sensing, Dual Shatter Recognition, Tamper Supervision, and 2GIG eSeries Panel Compatibility
The 2GIG GB1e is an encrypted glass break sensor for 2GIG eSeries security panels, including the GC2e and GC3e. Operating on the 345 MHz eSeries encrypted frequency, the GB1e detects the sound of breaking glass within a 15-foot radius using dual shatter recognition technology that analyzes both the initial impact and the sustained sound of glass fracturing. The 360-degree horizontal sensing angle covers an entire room from a single ceiling-mounted or wall-mounted position.
The encrypted 345 MHz protocol protects sensor signals from interception or replay attacks, and tamper supervision alerts the panel immediately if the sensor housing is opened or removed from its mounting surface. Two built-in test LEDs confirm proper operation during installation and routine maintenance checks. ETL-listed construction and battery-powered operation eliminate the need for dedicated wiring to each sensor location.
Where the GB1e Fits
- Residential properties with ground-floor windows and glass doors where the 15-foot detection radius and 360-degree sensing angle cover an entire room from a single ceiling-mounted sensor, dual shatter recognition reduces false alarms from non-glass impacts, and encrypted communication prevents signal interception in neighborhoods with overlapping security systems
- Commercial storefronts and retail locations where large glass display windows and entry doors are primary intrusion points, the GB1e adds perimeter detection that triggers before an intruder fully enters the space, and battery-powered wireless installation avoids running new wiring through finished commercial interiors
- 2GIG eSeries alarm system expansions where existing GC2e or GC3e panels need additional perimeter coverage beyond door and window contacts, the encrypted protocol matches the security level of the rest of the eSeries sensor network, and ceiling or wall mounting adapts to different room layouts without additional hardware
What the GB1e Delivers
- Encrypted 345 MHz Communication: The eSeries encrypted protocol secures all sensor-to-panel transmissions against interception and replay attacks. Fully supervised operation alerts the panel to low battery, tamper events, and communication loss.
- 15-Foot Detection Range with 360-Degree Coverage: A single GB1e covers a 15-foot (4.6 m) radius with 360-degree horizontal sensing, protecting an entire room of glass surfaces from a single mounting point on the ceiling or wall.
- Dual Shatter Recognition Technology: Two-stage acoustic analysis identifies both the initial impact and the sustained breaking pattern of glass, reducing false alarms from non-glass sounds like dropped dishes or nearby construction noise.
- Battery-Powered Wireless Installation: No wiring required from sensor to panel. Battery operation and wireless 345 MHz communication allow placement anywhere within range of the GC2e or GC3e panel without pulling cable through walls or ceilings.
How Does a Glass Break Sensor Work?
Glass break sensors use acoustic detection to identify the specific sound signature of breaking glass. When glass fractures, it produces a distinctive two-part sound pattern: a low-frequency thud from the initial impact followed by high-frequency vibrations as the glass shatters. Dual shatter recognition technology in the GB1e analyzes both components and only triggers an alarm when both are detected in the correct sequence and within the expected frequency range. This two-stage verification is what separates confirmed glass break events from similar sounds like dropped objects, slamming doors, or barking dogs. The 360-degree sensing angle means the microphone responds equally to glass breaking in any direction within its 15-foot radius, so a single sensor can protect multiple windows in the same room.
