Motion sensor Busch Jaeger Wächter 220° BT Stainless Steel, 220° detection angle, Bluetooth

The Busch Jaeger Wächter 220° BT Stainless Steel is a wall-mounted motion sensor engineered for broad-area presence detection and Bluetooth-enabled configuration. With a 220° detection angle and a robust stainless steel finish, this sensor is intended for indoor installations where reliable automatic lighting control, occupancy sensing and long-term durability are required. Bluetooth connectivity allows wireless setup and adjustments, while the metal housing offers a professional appearance and increased resistance to wear compared with standard plastic units.

Advantages

The wide 220° detection angle covers a large field of view, reducing blind spots and enabling accurate detection of movement across corridors, stairwells and open rooms. Bluetooth support simplifies commissioning and parameter tuning from a compatible mobile device without the need to access the sensor physically. The stainless steel housing improves mechanical durability and is suitable for visible locations where a high-quality finish is preferred. The device is designed for energy-efficient operation by enabling automated on/off switching of lighting based on occupancy.

Suitable for

• Corridors and hallways in residential or commercial buildings
• Stairwells and landings where broad-angle coverage is required
• Entrances and foyers with visible mounting locations
• Utility rooms, storage areas and service zones requiring automatic lighting control

Key specifications

• Detection angle: 220° for wide-area coverage
• Mounting type: wall-mounted installation
• Housing material: stainless steel finish for enhanced durability
• Connectivity: Bluetooth for wireless configuration and parameter adjustment
• Function: presence/motion detection for automatic switching of lighting and control systems

How to use

Install the sensor on a vertical surface at the recommended height and orientation to ensure the 220° detection zone covers the intended area. After electrical connection following local wiring standards and safety regulations, use a compatible smartphone or tablet to pair with the sensor via Bluetooth and configure detection sensitivity, hold time and light-level thresholds as required. Verify the coverage by walking through the detection area and make minor adjustments to angle or position if necessary.

Usage recommendations

For reliable detection, avoid mounting opposite large glass surfaces or heat sources that may generate false triggers. Choose a mounting height that allows unobstructed sight lines across the monitored area. For networked installations, ensure the Bluetooth range is sufficient during commissioning and keep firmware and smartphone app updated to maintain compatibility and performance.
