Door/window sensor SATEL XD-2L wired white — magnetic contact sensor for alarm systems

The SATEL XD-2L wired white door/window sensor is a compact magnetic contact sensor designed for integration with alarm and access-control systems. Intended for installation on doors and windows, the device monitors contact state changes and transmits signals to the control panel over a wired connection. The detector's design allows it to operate in multiple modes — as a magnetic contact, as a shock detector, as a combination of shock detector and magnetic contact, and as a water flood detector — providing versatile use in residential and commercial security installations.

Advantages

The XD-2L offers flexible functionality in a single compact unit, enabling magnetic contact detection and vibration sensing without requiring separate devices. Its wired connectivity ensures stable, low-latency signaling to a control panel and simplifies integration with existing alarm systems that support wired inputs. The white enclosure and small form factor allow discreet mounting on frames and sashes, while the multipurpose operating modes expand application options beyond simple open/close detection.

Suitable for

• Monitoring doors and windows in homes and apartments
• Securing commercial premises such as offices and retail shops
• Use in access-control systems requiring wired contact inputs
• Locations where combined shock and contact detection is needed

Key specifications

• Detector type: wired magnetic contact with multi-mode operation
• Operating modes: magnetic contact, shock detector, combined shock and magnetic contact, flood detector
• Mounting: surface mounting on frames and sashes
• Color: white
• Connection: wired interface for direct connection to alarm control panels
• Form factor: compact, low-profile enclosure suitable for discreet installation

How to use

Install the XD-2L on the door or window frame and the corresponding magnet on the sash so that the two elements align when closed. Connect the sensor's wires to the alarm control panel following the panel manufacturer's wiring diagram for a normally closed or normally open contact as required. If using shock detection or combined mode, configure sensitivity and input type on the control panel according to installation requirements. For flood detection use, position the detector where water ingress is most likely to be detected and connect it to an appropriate input on the control system. After wiring, test each operating mode using the control panel's diagnostics to confirm correct signaling.

Usage recommendations

Place the sensor where the magnet and detector can reliably align when the door or window is closed and avoid mounting on unstable or vibrating surfaces that could cause false alarms. Use the wired connection to route signals to the nearest compatible alarm control panel and verify settings for shock sensitivity and flood detection in the system software or panel configuration. Periodically inspect mounting and wiring for wear or corrosion.
