2GIG GB1
Wireless Glass Break Detector
Description
The 2GIG GB1-345 is a wireless glass break detector designed to protect any glass entry point such as windows, fixed glass panes and sky lights. This device belongs to the 2GIG family of 345 MHz wireless security sensors and will communicate with the 2GIG Go!Control self-contained alarm system. It is tamper protected so that if anyone tries to disable to open and disable the device the system will be notified. Also it is fully supervised to protect against RF communication failure. The unit is fully battery powered and runs off of 2 lithium batteries.
Like most glass breaks, the GB1-345 uses a finely tuned microphone designed to trip an alarm based on the sound of breaking glass within a 15 foot maximum radius. There is a single microphone built into the glass break detector. However there is dual stage technology that listens for a "thud" and "crash" independently. If the unit is laid flat on the bottom it has a 360 degree area of detection. However if it is wall mounted than this ares is limited to 180 degrees.
The minimum area of glass the detector supports is 11 inches by 11 inches. Also, plate, tempered and sealed insulating glass types must be between 1/8 and 1/4 inches in thickness. Keep in mind, for sealed insulating glasss, both panes of glass must be broken. Any glass outside of these parameters will not trip the device!
Glass break detection is a preventative method that in some cases will trigger an alarm before an intruder has even stepped foot into the premise. It is a great way to protect fixed glass panes that are commonly found in bay windows, sliding doors and sky lights. If there is a way to integrate glass break detection with your security system it is worth it. It adds an extra layer of protection against criminals familiar with circumventing door and window contacts by smashing through glass panes and crawling into your secured premise.
The Honeywell Lyric alarm system now supports this sensor with the release of the MR3 firmware update!

The 2GIG GB1 is a wireless glass break detection sensor that operates at the 2GIG 345 MHz frequency. This makes it compatible with all of the 2GIG Systems, as well as the Honeywell Lyric Alarm System and the 345 MHz version of the Qolsys IQ Panel 2 Plus. The sensor actively listens for the sound of glass breaking. Once activated, it will alert the system to the glass break event. The system will then respond based on the programming settings for the zone. Overall, we really like the 2GIG GB1 Glass Break Sensor, and we give it a 5 Star rating.
There are many things to like about the 2GIG GB1. For one, the sensor has a finely tuned microphone that reliably responds to the sound of glass breaking, while ignoring similar sounds. The sensor also prevent against false alarms by requiring that both the sound of the glass shattering and the sound of an object striking against the glass be present for activation. We also like the fact that the 2GIG GB1 offers tamper detection to let the system know if anyone tries to open or disable the sensor. And we appreciate its 360-degree coverage area when ceiling-mounted.
There are some minor downsides regarding the 2GIG GB1. One is that the sensor only works with certain types of glass. Make sure the glass you are monitoring is compatible. And like any wireless sensor, you will need to replace the batteries periodically. There is also the consideration that when the unit is wall-mounted as opposed to ceiling-mounted, the coverage area will only be 180 degrees. But these downsides are very minor, and they do not stop us from awarding the 2GIG GB1 a perfect 5 Star score.
Good: Finely Tuned Microphone, Prevents False Alarms, Tamper Detection, 360-Degrees Coverage Area When Ceiling-Mounted
Bad: Only Works w/ Certain Types of Glass, Requires Battery Replacements, Wall-Mounting Reduces Coverage Area
Bottom Line: 5 Stars
