About the ADT 2X16AIO LCD Command Panel
The ADT 2X16AIO “Defender” is an all-in-one security and smart home control panel developed by Resideo (Honeywell Home) for ADT security systems. Designed to simplify home protection, the panel combines intrusion detection, fire and carbon monoxide monitoring, emergency response features, and home automation into a single interface. With built-in Wi-Fi and cellular communication, it helps keep your security system connected even if one communication path is interrupted.
The system offers multiple arming options—including Stay, Away, Night Stay, Instant, Maximum, and Custom modes—allowing homeowners to tailor protection to their daily routines. It also supports up to 96 user codes with customizable authority levels, making it easy to manage access for family members, guests, or service providers.
Beyond security, the ADT 2X16AIO integrates with compatible Z-Wave smart home devices such as lights, locks, thermostats, and garage door controllers. When connected to Alarm.com services, users can remotely arm or disarm the system, receive real-time alerts, review activity, and control supported smart home devices from virtually anywhere using a smartphone or web browser.
The user manual covers everything needed to operate the system confidently, including arming and disarming procedures, bypassing zones, managing user codes, using emergency panic functions, testing the system, connecting to Wi-Fi, replacing sensor batteries, viewing event history, and controlling smart home devices.
