ADT smart model troubleshooting

ADT Base (ADTBASE502R0); the central hub that manages every ADT Blu sensor and device, with its own built-in keypad, siren, Emergency response buttons (professionally monitored only), AC power with battery backup, Wi-Fi (2.4/5 GHz) and cellular uplink.

• ADT Base ADTBASE502R0

ADT Keypad (SKP5R0-01); a secondary in-home controller for arming/disarming and triggering a panic alarm, with its own non-swappable lithium-ion backup battery — a different power path from the Base's own backup.

• ADT Keypad, Keychain Remote and Yale Assure Lock 2 SKP5R0-01; also Yale Assure Lock 2 / Lock 2 Touch (Yale Assure Lock 2 or Lock 2 Touch (no separate model number — the interior mounting plate label and the fingerprint reader distinguish the Touch variant))

ADT Door/Window Sensor (SSH5R0); a single CR2-battery magnetic contact sensor and separate magnet, mounted a maximum of 1/2 inch apart.

• Door/Window Sensor SSH5R0

ADT Premium Door/Window Sensor (SSHX5R0); adds a built-in shock sensor for forced-entry detection and a Bypass button the standard Door/Window Sensor does not have, on the same CR2 battery.

• Premium Door/Window Sensor SSHX5R0

ADT Motion Sensor (SSM5R0-29); a pet-friendly, single-CR123A-battery sensor rated for roughly 32 feet of detection range at the recommended 6.5-foot corner mount.

• ADT sensors and detectors (Motion, Door/Window, Glass Break, Smoke, Heat, CO, Water and Temperature, Indoor Siren and Live Light) SSM5R0-29

ADT Glass Break Sensor (SSGB5R0); listens for the acoustic signature of breaking glass rather than a magnetic contact or motion, on four CR123A batteries, and performs best mounted on the wall opposite the glass it monitors.

• Glass Break Sensor SSGB5R0

ADT Water and Temperature Sensor (SSW5R0-29); a single-CR123A-battery sensor with an external extension probe for wall-mounting, which reports ambient temperature to the ADT+ app roughly every 15 minutes in addition to water detection.

• Water and Temperature Sensor SSW5R0-29

ADT Smoke Detector (SSS5R0); three CR123A batteries, operates independently of the system's arm state, and does not detect carbon monoxide or heat — a different model from the CO-only, heat-only and combined Smoke and CO detectors.

• Smoke Detector SSS5R0

ADT Carbon Monoxide Detector (SSCO5R0); two CR123A batteries, operates independently of the system's arm state, and does not detect smoke or fire — a different model from the smoke-only, heat-only and combined Smoke and CO detectors.

• Carbon Monoxide Detector SSCO5R0

ADT Smoke and Carbon Monoxide (CO) Detector (SSSX5R0); three CR123A batteries, a dual-function device that is a different model from the standalone smoke-only and CO-only detectors, not a firmware variant of either.

• Smoke and Carbon Monoxide Detector SSSX5R0

ADT Heat Detector (SSHE5R0); two CR123A batteries, monitors for dangerously high or fast-rising temperature, and the manufacturer's own article states explicitly that this model does not detect carbon monoxide.

• Heat Detector SSHE5R0

ADT Indoor Camera (VMC3060-1ADNAS); mains-powered over its included power adapter (no battery), with 2K live streaming and a built-in privacy shield, and joins the home Wi-Fi network directly rather than ADT's proprietary sensor RF.

• ADT cameras and doorbell camera (Indoor, Outdoor and Doorbell) VMC3060-1ADNAS

ADT Outdoor Camera (VMC3050-1ADNAS); runs on a non-removable rechargeable battery charged over USB-C rather than mains power, and joins the home Wi-Fi network directly rather than ADT's proprietary sensor RF.

• Outdoor Camera VMC3050-1ADNAS

ADT Doorbell Camera (AVD4001-1ADNAS); ADT's own article documents both a battery-powered and a wired-to-the-existing-doorbell-circuit installation for this same model, and it joins the home Wi-Fi network directly rather than ADT's proprietary sensor RF.

• Doorbell Camera AVD4001-1ADNAS

ADT Indoor Siren (SAH5R0-29); two CR123A batteries, an add-on that amplifies the Base's own alarm sound in a separate room rather than functioning as a standalone alarm.

• Indoor Siren SAH5R0-29

ADT Keychain Remote (SKF3R0-29); a single CR2450 coin-cell battery, rated by ADT for roughly 75 feet of range from the Base, and assigned to exactly one ADT+ app user during setup.

• Keychain Remote SKF3R0-29

ADT Live Light; an outdoor illuminated yard sign on three AA lithium batteries that connects to the Base over the DECT ULE protocol — a different radio from the other battery sensors — and illuminates automatically during an alarm event or on manual activation.

• Live Light ADT Live Light (no separate model number — the label inside the battery compartment names the product itself)
