Door/window opening sensor X-Sense SDS0A wireless battery-operated

The X-Sense SDS0A wireless battery-operated door and window opening sensor detects opening events at doors and windows and integrates with the compatible SBS50 base station and the X-Sense Home Security app. Compact and lightweight, the sensor is designed for retrofit or new installations and mounts with double-sided tape without tools. It is suitable for homes, small offices and multi-family buildings where a tamper-resistant contact sensor is needed to monitor access points and provide instant alerts via the connected security system.

Advantages

The sensor supports a long battery life with a replaceable AAA cell and a built-in indicator for status and event feedback. It communicates reliably over long distances in open spaces, simplifying placement across larger properties. Installation requires no wiring, and the device is compatible with the SBS50 base station and the X-Sense Home Security app for push notifications, alarm timing control and scheduling between Home and Away modes. The compact white enclosure and low weight make it unobtrusive on most door and window frames.

How to use

Install the sensor and magnet on the door or window frame so that they align when the door or window is closed; the supplied double-sided tape mounts the units without tools. Insert the provided AAA battery following polarity markings and pair the sensor with the SBS50 base station using the pairing procedure in the X-Sense Home Security app. Confirm alignment and run a test open/close cycle in the app to verify signal reception and correct event reporting. Configure alarm intervals, push notifications and schedule Home/Away modes from the app.

Usage recommendations

Place the sensor and magnet within the recommended gap for reliable detection and avoid direct exposure to heavy rain or extreme temperatures. Replace the AAA battery when the app indicates low battery and periodically test the sensor through the app to ensure continued connection to the base station. For uninterrupted alarm operation, consider a UPS for the local Wi‑Fi router and SBS50 base station.
