Functions
The sensor detects human walking, slight motion (such as body movement, turn up head and others minor movements) and breathing to realize the detection of human existence in non-sleep state.
- Movement signal: Major movement for sensor triggering.
- Slight motion signal: Very small movement even only body motion can be collected
the indicator flashes once. - Breathing signal: When no slight motion signal, only breathing signal can be
collected, the indicator flashes 3 times by detecting 3 effective breathing signals.
Movement Signal Active
Slight Motion & Breathing Signal Maintain
- Movement signal: Major movement for sensor triggering.
- Slight motion signal: Very small movement even only body motion can be collected
the indicator flashes once. - Breathing signal: When no slight motion signal, only breathing signal can be
collected, the indicator flashes 3 times by detecting 3 effective breathing signals.
1
When ambient light is sufficient, the light will not turn on even when movement signal is detected.
2
When ambient light is insufficient, the light will turn on automatically when movement signal is detected.
3
The body, head and other small movements during normal work can be detected and light will be on.
4
When the sensor fails to detect movement or slight motion, the light will automatically turn off after the delay time.

The first power on, sensor enter self-test mode, and the self-test will be completed after 20 seconds to enter the normal working state. During the initialization, the external motion signal will not be detected, remote control signal is not received.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.
5) The microwave sensor has a certain penetrating ability to the wall of the building, and the microwave penetrating to the outside of the wall may cause false alarm when it ACTS on the moving objects outside the fortified area. To avoid triggering by mistake, the installation position and appropriate induction range should be selected during installation.
6) The data on detection pattern is typical value tested in factory, the detection range could be affected by moving speed, installation height, motion object and different environment.
Frequently asked questions
What can SpaceCheck detect?
It detects walking movement up to 4-5 m radius, slight motion up to 4-5 m and breathing up to 3-4 m, across a 150° detection angle.
What hold time should I set for presence detection?
Set the hold time to at least 1 minute for breathing detection. The 5 second setting is for motion testing only.
How does the daylight sensor save energy?
When ambient light is above the chosen threshold (5, 25 or 50 lux), the light stays off even if movement is detected.
