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.

Troubleshooting
Quick diagnostic flow
- Confirm exact model/SKU on label matches official install guide.
- Clear panel AC and cell troubles before diagnosing wireless devices.
- Read zone trouble — tamper and low battery before "missing."
- Verify 345 MHz vs eSeries vs ePlus sensor matches panel hardware.
- For cell modules: ICCID, antenna, RSSI, and dealer platform match.
- Power-cycle panel only per dealer policy — document user codes first.
Symptom-based fixes
| Symptom | Likely cause | Fix |
|---|---|---|
| Zone missing | Range or battery | Replace battery; add RPTR1 repeater or XCVR2 path |
| Encryption trouble | Wrong sensor series | Use eSeries on e panel or standard sensor on non-e |
| Cell fail persists | SKU or activation | Correct LTE module; dealer activates Alarm.com |
| Z-Wave won't include | Prior hub pairing | Exclude from old controller; include near panel |
| Takeover false alarms | Wired loop fault | Check EOL wiring; verify burglary-only zones |
| Cannot arm | Open zone or trouble | Status screen — secure or bypass per policy |
Testing checklist
| Test | How | Pass criteria |
|---|---|---|
| Zone status | Panel zone list | Secure when normal; open when tripped |
| Tamper | Open cover | Trouble shows; clears closed |
| Walk test | Installer walk test | Event at panel for trip |
| Final location | 24-hour soak | No missing or low battery |
After replacement
Delete old zone, enroll new hardware, update zone name, run walk test, and notify monitoring dealer if central station records zone numbers.
