Product Information
Full details
This GTV Motion Sensor is designed for individuals seeking reliable and automatic lighting control in various indoor spaces. Its key benefit is its ability to detect human presence using infrared energy, ensuring lights activate only when needed, both day and night, saving energy and enhancing convenience. A minor caveat is its specific installation requirement for false ceilings within a certain height range. The sensor utilizes infrared detection, offers adjustable sensitivity and hold-up times, and operates effectively in diverse lighting conditions.

FAQs
What is the maximum detection range of this motion sensor?
The maximum detection range for this GTV motion sensor is up to 8 meters.
Can this sensor be used outdoors?
No, this sensor is designed for indoor use, specifically for installation in false ceilings.
How do I adjust the time the light stays on after motion stops?
The sensor features an adjustable hold-up time, with options ranging from 10 seconds to 15 minutes. This is typically adjusted via a dial or switch on the sensor itself.
Does the sensor work in complete darkness?
Yes, the sensor has a mode (marked as '3' on the light sensitivity setting) that allows it to activate at light levels below 3 LUX, ensuring it functions effectively even in dark conditions.
What is the recommended installation height?
The recommended installation height for optimal performance is between 2.2 and 4 meters in a false ceiling.
How does the 'sun' setting differ from the '3' setting?
The 'sun' setting typically means the sensor will operate regardless of the ambient light level (day or night). The '3' setting means the sensor will only activate when the ambient light level drops below approximately 3 LUX, making it suitable for darker environments or when you don't want it to trigger in bright daylight.
What type of detection does this sensor use?
This sensor uses passive infrared (PIR) detection, which senses the infrared energy emitted by the human body.
Troubleshooting
Sensor not detecting motion
Verify power supply to the sensor. Ensure the detection range is not obstructed. Check if the sensor is set to an appropriate mode for current light conditions (e.g., 'sun' mode for bright environments). Clean the sensor lens.
Light stays on continuously
Check the hold-up time setting; it may be set to the maximum duration. Ensure there isn't constant movement or heat source within the detection range that the sensor is interpreting as occupancy. Test by setting a shorter hold-up time.
Light does not turn off after exiting the room
Confirm the hold-up time is set appropriately. Ensure no residual heat or motion is being detected within the sensor's range. The sensor might be too sensitive or positioned to detect activity outside the intended area.
Sensor is less sensitive than expected
Ensure the sensor is installed at the recommended height (2.2-4m). Check for any physical obstructions blocking the sensor's view. Clean the sensor lens as dust buildup can reduce sensitivity.
Pros and Cons
Pros
- Reliable motion detection using infrared technology.
- Flexible operation modes for both daytime and nighttime use.
- Customizable lighting duration with adjustable hold-up times.
- Wide detection range covers significant areas.
- Designed for straightforward recessed ceiling installation.
Cons
- Requires a false ceiling for installation.
- Installation height is specific for optimal performance.
- Detection relies on infrared energy emission, may not detect non-heat-emitting objects.
- Limited to indoor use where false ceilings are present.
Setup, Compatibility & Care
Setup:
- Mounting: The sensor is designed for recessed installation into a false ceiling. Ensure the ceiling material can support the sensor and that the cutout matches the sensor's dimensions. The recommended installation height is between 2.2 and 4 meters from the floor.
- Wiring: Connect the sensor to your lighting circuit according to the manufacturer's wiring diagram. Ensure power is disconnected before attempting any electrical connections.
- Adjustment: Set the desired hold-up time (10 s to 15 min) and select the light sensitivity mode ('sun' or '3' LUX) using the integrated controls on the sensor.
Compatibility:
- This sensor is designed to control lighting loads. Ensure the connected light fixture's power consumption is within the sensor's rated capacity.
- Compatible with standard AC electrical systems. Specific voltage requirements should be checked against the product's technical specifications.
Care:
- Keep the sensor lens clean. Gently wipe with a dry, soft cloth. Avoid using abrasive cleaners or solvents that could damage the plastic.
- Ensure the installation area is free from dust and excessive moisture, which could affect performance.
