SpaceCheck Pro. Presence Sensor
SpaceCheck Pro is a ceiling presence sensor for large spaces that uses 24 GHz millimetre-wave radar. Mounted at 3 m, it detects motion, minor motion and breathing across about 5 to 7 m in diameter. A daylight sensor and NO/NC dry contact output link occupancy to lighting, HVAC and BuildOT One.
A cutting-edge large space presence sensor for accurate and reliable presence detection
The sensor employs orthogonal half-wave bending antenna, capable of detecting minor movements, such as breathing, ensuring comprehensive coverage of the monitored area. SpaceCheck Pro is ideal for large spaces, providing fast and precise presence or absence information, thereby enhancing security, comfort, and energy efficiency. Its robust design and versatile installation options make it an essential component for modern building management systems.

Detection Pattern
SpaceCheck Pro detects human motion, minor motion, and presence signals, and realizes the detection of human-existing/no-human in non-sleep state.
The following is a description of the moving, minor moving and presence signals:
- Motion signal: detect the human significant moving (walking) in the detection area.
- Minor Motion signal: detect the human slight movement in the detection area, such as leaning forward, leaning forward and back, swinging limbs, shaking head, typing, mobile phones usage etc.
- Presence signal: Detect human abdominal and thoracic expansion behaviors caused by breathing, but not detect moving signal and minor moving signal.
Factory Settings
Indicator light: On Detection Area: 100% Hold Time: 1min Daylight Sensor: Disable
Initialization
When powered on, the sensor indicator will turn off after flashing for 20S and will not
detect moving signal during this time. After 20S, you can use the remote to adjust
detection area, hold time and daylight sensor etc parameter.
Remote Settings
Application Notice
1) The sensor should be installed by a professional electrician. Please disconnect the power before installing, wiring or changing the setting of the DIP switch.
2) Put the sensor as far as possible from large areas of metal plate, glass and other
materials with high medium density to avoid triggering by mistake.
3) Avoid using objects that have been vibrating for a long time around the sensor,
such as shaking fans, etc. The vibration signal will be regarded as the motion signal to
trigger the sensor
4) Avoid the detection window of the daylight sensor of the detector irradiated by an
invalid light source, which will interfere with the measurement of ambient light.
Frequently asked questions
How is SpaceCheck Pro different from SpaceCheck?
SpaceCheck Pro uses 24 GHz millimetre-wave radar for large spaces and offers NO or NC output. SpaceCheck uses 5.8 GHz microwave sensing for standard rooms.
What mounting height does SpaceCheck Pro need?
Mount it between 2.5 and 4 m. At 3 m, the presence detection radius is about 2.5 to 3.5 m.
How is SpaceCheck Pro configured?
Detection area, hold time and daylight threshold are set with a remote control.
