24GHz Occupancy detector with NO contact and NC contact with AC input

This embedded dry contact occupancy detector utilizes 24GHz millimeter-wave radar technology to detect movement, slight motion, and breathing signals, enabling accurate human presence detection while distinguishing between human and non-human targets.

• Advanced life-being detection technology capable of identifying movement, slight movement, and breathing signals
• Reed tube relay design ensures silent operation, ideal for hotel applications
• Compact installation size suitable for smart buildings, intelligent hotels, smart offices, and presence detection systems
• 24-24.25GHz (ISM band) millimeter wave radar with no interference to 5G WiFi and no penetration through solid walls

The sensor detects human walking, slight motion (such as body movement, turning the head, and other minor movements), and breathing to enable detection of human presence in non-sleep states.

• Movement signal: Large movements that trigger sensor activation within the detection area
• Slight motion signal: Very small movements including leaning forward, leaning back, body swinging, head shaking, typing, and mobile phone usage
• Breathing signal: Detection of breathing patterns through abdominal and chest cavity dilation

1. Cut a 55mm hole in the ceiling
2. Remove the crimping cover using a flat-head screwdriver
3. Connect the wire to the terminal
4. Install the wire cover and press the wire securely
5. Bend the spring clamp backward to push into the pre-opened ceiling hole
6. Ensure stable and reliable installation

1. Cut off the reserved thin wall for the thread
2. Fix the product on the target mounting surface with matching screws
3. Connect the input wire to the wiring terminal and close the cover tightly
4. Remove the top cover with a flat-blade screwdriver
5. Adjust the DIP switches and parameters, then replace the top cover
6. Push the product into the ceiling seat until the buckle fastens securely
7. To remove, insert a flat-blade screwdriver into the disassembly gap and pry downward
8. Ensure stability and reliability after installation

Remote control settings support sensitivity adjustment, delay configuration, ON/OFF control, reset functions, sensor motion settings, and indicator light switching.

Upon first power-up, the sensor enters self-test mode for 20 seconds before transitioning to normal operation. During initialization, external motion signals are not detected and remote control signals are not received.

• Detection Area: 100%
• Hold Time: 1 minute
• Daylight Sensor: Disabled
• Indicator Light: Enabled

When set to "disable", the lamp will switch on when motion is detected, regardless of ambient light level.

• Installation should be performed by a qualified electrician
• Keep away from large metal plates, glass, and high-density materials to prevent false triggering
• Avoid installation near high-current circuits that may affect product operation
• When installing multiple units, ensure antenna surfaces are parallel and spaced more than 1m apart
• Avoid facing antenna surfaces toward AC drive power supplies and high-power devices
• Avoid long-term vibrating objects near the product
• Prevent unnecessary light from illuminating the illuminance sensor detection window
• Select appropriate detection area based on room dimensions:
  • 25% for rooms approximately 2m or less (washrooms, sitting rooms)
  • 50% for rooms approximately 3m (washrooms, hallways, sitting rooms)
  • 75% for rooms approximately 4m (small offices, meeting rooms, libraries)
  • 100% for rooms approximately 5m or more (large offices, meeting rooms, libraries)
• Detection distance varies based on movement speed, object size, installation height, angle, and environmental factors
• Product specifications and parameters may be optimized without prior notice
