Overview
2GIG glass break detector — acoustic glass-break detection for protected windows within rated distance (GB1 / GB1e / ePlus variants).
On 2GIG systems, wireless devices are supervised zones on the panel — tamper, low battery, and missing signals appear as trouble conditions that may block arming depending on panel programming.
