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.
