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.
At a Glance
| Specification | Details |
|---|---|
| Detection | Water probe contact and/or temperature threshold |
| Wireless | 345 MHz; encrypted FT1e available |
| Placement | Floor pan, drip tray, sump pit lip per manual |
| Alerts | Panel chime/trouble; central station if monitored |
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.

Error Codes
2GIG systems report faults on the panel and keypad status screens, zone list, and Alarm.com (when interactive service is active) — not as a single universal numeric code list across all models.
How to read status
- Open panel status or installer menu → zones / troubles.
- Note zone number, trouble type (open, tamper, low battery, missing, cell fail).
- Cross-check Alarm.com device list if the account is interactive.
- For cell issues, run installer communication test before replacing sensors.
Common trouble indicators
| Symptom | Meaning | First checks |
|---|---|---|
| Zone trouble / missing | Sensor not supervised | Battery, range, tamper, re-enroll |
| Tamper | Cover open | Reseat cover; bracket secure |
| Low battery | Sensor battery weak | Replace with listed type — all cells in multi-cell devices |
| Chronic open (contact) | Magnet gap | Realign; check door warp |
| No response | Wrong RF path | Repeater or transceiver for distance; ePlus needs XCVR2 |
