Overview
2GIG flood, water leak, or temperature sensor — environmental zone for sump, water heater, and freeze alerts (FT1, water leak, dual flood/temp SKUs).
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.
