What This Device Does Well
Provides reliable status reporting and user-facing alerts through the ADT+ or ADT Control app when installed and enrolled correctly.
Before You Service or Replace One
- Platform — Command SiX vs Self-Setup sensor family — battery type and reset steps differ.
- Hub/panel online — must show connected in app before diagnosing sensor.
- Range — distant devices may need Range Extender, not a new sensor.
- Tamper — cover fully closed before declaring hardware fault.
- Monitoring mode — Practice/disarmed modes affect whether alarms dispatch.

- Confirm exact model/generation on label matches official setup article.
- Verify ADT+ or ADT Control app Location matches physical site and you have owner/shared access.
- For alarm devices: confirm Command panel / Self-Setup hub online before replacing sensors.
- Read device status — resolve Tampered/Low Battery before diagnosing Offline.
- For cameras/doorbells: test Wi-Fi RSSI at mount — not at router.
- Power-cycle device and hub/router if fault persists after battery swap.
Symptom-based fixes
| Symptom | Likely cause | Fix |
|---|---|---|
| Offline immediately after install | Enrollment incomplete | Remove device; factory reset; add within 3 m of hub (alarm) or good Wi-Fi (video) |
| Intermittent offline | Range or power | Range Extender (Z-Wave); Chime Pro or mesh Wi-Fi (video) |
| Tampered won't clear | Cover or bracket | Reseat cover; tighten mount; check tamper pin |
| Low battery returns quickly | Wrong battery or cold | Official battery SKU; replace all cells if multi-cell |
| Alarm won't arm | Open fault | device status list — close/bypass per user policy |
