2GIG GB100-345 - Data Sheet (2025)

The 2GIG
®
GB100-345 is a fully supervised, tamper-
protected, ceiling- or wall-mounted, wireless glass
break detector. It utilizes a dual-stage glass break
detection method that listens for both the impact of
an object hitting the glass (“thud”) and the sound of
the glass shattering (“crash”). This helps to minimize
false alarms triggered by sounds similar to breaking
glass. The sensor transmits in nonencrypted mode
by default, and can be set to encrypted mode via an
onboard switch.
