The EAE CD100 KNX Corridor Sensor is a ceiling-mounted passive infrared (PIR) detector designed for long, narrow spaces — corridors, hallways, and car parks. Its 180° lens geometry and corridor-specific detection pattern deliver up to 20 m × 6 m coverage (tangent walk at 4.5 m mounting height), far beyond standard 360° presence detectors.

An integrated brightness sensor enables constant-light control and the dedicated corridor function — adjustable brightness levels for motion detected, after movement, and no movement states. Separate HVAC and presence monitoring channels extend control beyond lighting. The CD100 is KNX bus-powered (no external supply) and available in flush-mounted and surface-mounted versions.

Key Features — 20 m × 6 m Corridor Detection

Detection and Coverage

• Corridor-optimised PIR: 180° detection angle for long linear spaces.
• Maximum coverage: 20 m × 6 m (tangent walk) or 12 m × 4 m (radial walk) at 4.5 m height — up to 120 m².
• Mounting height: 2.5 m – 4.5 m recommended.
• Brightness sensor: 1 – 1000 lux for constant-light regulation.

Control Functions

• Corridor function: Separate brightness and timing for motion, after-movement, and idle states.
• Constant-light function: Maintains a defined lux level by comparing ambient light with the setpoint.
• HVAC channel: Independent communication object for air-conditioning and ventilation.
• Presence channel: Sends occupancy status to monitoring applications.
• Operating modes: Fully automatic or semi-automatic (with external button/switch override).
• Parallel operation: Master/Master or Master/Slave with other KNX sensors for extended corridors.
• Test and calibration mode: Simplifies commissioning and lux-sensor adjustment.

Applications and KNX Integration

• Hotel corridors: Corridor function with staged dimming for guest safety and energy savings.
• Office hallways: Constant-light control linked to dimmable luminaires or DALI via a gateway.
• Car parks and basements: Long-range detection with master/slave chaining for extended runs.
• General rooms: For 360° presence detection in offices and meeting rooms, choose the EAE PD100 KNX Presence Detector.
• High-ceiling spaces: For warehouses and halls at 7 – 14 m height, use the EAE HD100 High Bay Movement Sensor.
• DALI lighting: Pair with the EAE DA100 DALI Gateway for constant-light dimming of DALI luminaires.

Choosing EAE KNX Sensors

The CD100 is the corridor-specialist in the EAE XD100 sensor family — choose it when coverage must extend along a long axis. For round 360° rooms, step to the PD100 (presence) or MD100 (motion). For high-bay industrial ceilings, choose the HD100. All share KNX bus power and the corridor/constant-light/HVAC feature set.
