The EAE PD100 KNX Presence Detector F/S is a ceiling-mounted PIR presence detector with integrated brightness sensor for offices, meeting rooms, classrooms, and other interior spaces. Available in flush-mounted and surface-mounted versions, it provides 360° detection with presence-optimised sensitivity — detecting seated persons as well as walking movement.

The PD100 is part of the EAE XD100 sensor family and shares the corridor function, constant-light control, HVAC channel, and presence monitoring features with the CD100 and HD100. It is KNX bus-powered (no external supply) and supports master/slave parallel operation for large or irregular rooms.

Key Features — 360° Presence Detection

Detection and Coverage

• Presence-optimised PIR: Detects seated and walking occupants (PD100 variant of XD100 family).
• 360° coverage: Up to 64 m² area at recommended mounting heights.
• At 2.5 m height: 6 m seated / 7 m walking detection diameter.
• At 3 m height: 6.5 m seated / 8 m walking detection diameter.
• Mounting height: 2.5 m – 5 m recommended.
• Brightness sensor: 1 – 1000 lux.

Control Functions

• Constant-light function: Two lux setpoints for free and occupied states.
• Corridor function: Staged brightness for movement, after-movement, and idle.
• HVAC channel: Triggers heating, cooling, or ventilation on occupancy.
• Presence channel: Periodic presence status for monitoring applications.
• Operating modes: Fully automatic or semi-automatic with external override.
• Parallel operation: Master/Master or Master/Slave with other KNX sensors.
• Test and calibration mode: Verify detection range and lux calibration during commissioning.

Applications and KNX Integration

• Offices and open-plan workspaces: Presence-based lighting and HVAC with daylight compensation.
• Meeting and conference rooms: Occupied/unoccupied states drive lighting scenes and climate setpoints.
• Classrooms and lecture halls: Detects seated occupants — not just walking movement.
• Corridors: For long narrow spaces, the EAE CD100 Corridor Sensor offers optimised 180° coverage.
• High-ceiling halls: For 7 – 14 m mounting heights, choose the EAE HD100 High Bay Sensor.
• DALI constant-light: Pair with the EAE DA100 DALI Gateway for dimmable luminaire control.

Choosing EAE KNX Sensors

The PD100 is the general-purpose 360° presence detector — choose flush or surface mount to match the ceiling type. For motion-only detection (without seated presence), EAE offers the MD100 variant in the same XD100 housing. For corridor-length detection, choose the CD100; for high-bay warehouses, the HD100.
