Overview
5800 Series flood / temperature environmental sensor — water probe and freeze alerts (5800FLOOD, dual flood/temp SKUs).
On Honeywell 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.

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 5800 Series vs SiX encrypted 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 5800RP repeater or receiver placement |
| Encryption trouble | Wrong sensor series | Use SiX on ProSeries/Lyric or 5800 on VISTA/Lynx |
| Cell fail persists | SKU or activation | Correct LTE module; dealer activates Total Connect 2.0 |
| 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.
