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.
