Published specification
What is true of this model and changes how you fix it
- What it isA step up from the standard Door/Window Sensor (model SSHX5R0): the same magnetic contact function, plus a built-in shock/vibration sensor that detects forced-entry attempts like a door being struck rather than opened, and a Bypass button to temporarily suspend the sensor without disarming the whole system.
- PowerOne CR2 battery, included — the same battery type as the standard Door/Window Sensor, despite the added shock-detection hardware.
- Placement toleranceSame 1/2-inch maximum sensor-to-magnet gap as the standard Door/Window Sensor when the door or window is closed.
- SizeThe sensor is 2.99 x 0.92 x 0.87 in and the magnet is 1.67 x 0.59 x 0.52 in.
- Gap between sensor and magnetKeep the sensor and its magnet within 0.5 in (12.7 mm) when the door or window is closed. On deep trim, ADT sells a spacer that offsets the gap, so a sensor that reports open on a closed door is often too far from its magnet.
- BatteryOne replaceable CR2 battery. ADT lists up to four years of life, so a sensor that drops out or chirps for a low battery needs a fresh CR2 before anything else is changed.
- MountingIt mounts with pre-applied adhesive and needs no tools. Clean the surface first, since adhesive on dust or a painted trim edge is a common reason a sensor falls off and sends a tamper alert.

Exact questions
Questions that only have an answer for the ADT Premium Door/Window Sensor
What does the Premium Door/Window Sensor add over the standard one?+
ADT documents two real differences on the same CR2 battery: a built-in shock/vibration sensor that can detect a forced-entry attempt against the door itself (not just the door opening), and a physical Bypass button to suspend that one sensor without disarming the whole system.
Does the Premium sensor need a different battery?+
No. ADT lists the same single CR2 battery for the Premium Door/Window Sensor (SSHX5R0) as the standard model, even though it carries the added shock-sensor hardware.
Why does the sensor say open when the door is closed?+
Check the gap first: sensor and magnet must be within 0.5 in when closed. Realign them or add a spacer, then open and close the door to test.
What battery does the Premium Door/Window Sensor use?+
One CR2 battery, not the CR2032 coin cell used in some older ADT sensors.
