The GTV CR-20 is a professional-grade occupancy motion sensor designed for homeowners and office managers seeking automated lighting control to enhance safety and energy efficiency. It is an ideal solution for retrofitting corridors, hallways, and offices where hands-free light activation is preferred, though users should note it is strictly for dry indoor environments with an IP20 rating and is not suitable for damp or outdoor locations.

The CR-20 is optimized for LED loads. While it may support other types, ensure the total wattage does not exceed the 200W capacity.
No, the CR-20 has an IP20 rating, meaning it is not protected against moisture and should not be used in bathrooms or other damp areas.
Installation requirements depend on your specific wiring configuration. Always consult a qualified electrician to ensure compatibility with your wall box wiring.
The sensor is capable of detecting motion up to 10 meters away, provided there are no obstructions in the line of sight.
The detection angle is fixed at 120 degrees; coverage adjustments should be managed by the physical positioning of the sensor.
IP20 means the device is protected against solid objects larger than 12mm but has no protection against water or liquid ingress.
Verify that the daylight sensor setting is not preventing activation due to high ambient light, and ensure the sensitivity dial is not set too low.
Check the time-delay setting on the device; it may be set to a maximum duration. Also, ensure there are no heat sources moving within the detection zone.
Lower the sensitivity setting and ensure the device is not pointed toward an HVAC vent or a direct light source.
The CR-20 is designed for flush mounting into standard electrical boxes, making it a straightforward upgrade for existing light switch locations. Ensure the power is completely isolated at the breaker before beginning installation. Once installed, the adjustment dials for sensitivity and time are located on the face of the unit, allowing for easy calibration without disassembling the device. Maintain the device by periodically wiping the sensor lens with a dry, soft cloth to prevent dust buildup, which can reduce the detection range over time. Do not use chemical cleaners or liquids, as these may damage the plastic housing or the sensitive infrared lens.
