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.

What This Device Does Well
Provides reliable supervised status at the panel and Alarm.com when installed, enrolled, and range-tested correctly.
Before You Service or Replace One
- Sensor SKU — standard 345 MHz vs eSeries encrypted vs ePlus 900 MHz.
- Panel online — resolve panel AC/cell trouble before blaming sensor.
- Range — repeaters (RPTR1) or transceivers (XCVR2) for distant zones.
- Battery type — use listed cell; replace all batteries in multi-cell devices.
- Tamper — cover fully closed before declaring hardware fault.

How do I test after installation?
Use panel walk test, zone status, and (if monitored) central station test per dealer procedure.
Can I mix 345 MHz and ePlus sensors?
ePlus 900 MHz sensors require XCVR2 transceiver hardware — they do not enroll on the standard 345 MHz receiver alone.
