H-MOSS® Line voltage ceiling sensor. 30 seconds to 30 minutes fully adjustable time delay. 32.7 kHz operating frequency ultrasonic output. Multi-segmented, high-density Fresnel™ lens passive infrared. Walk test indicator, red infrared motion, green ultrasonic motion LED lamp. 360° up to 2000 sq-ft coverage. 5000 W at 50/60 Hz, 277 VAC load. 32 to 122°F operating temperature. Rugged, high impact, injection molded plastic, colour-coded leads housing. Sensors may be mounted using a single gang mud ring attached to a 4 inch square electrical box, recommended max mounting height 12 ft mounting. The LVDT2000R series is a line voltage ceiling mount sensor that uses dual Technology-Passive Infrared (PIR) and ultrasonic, to turn lighting loads on and off based upon occupancy. Dual Technology ensures maximum reliability and minimizes false triggering. As a line voltage sensor, it does not need a separate control unit. The LVDT2000R is an excellent choice for areas where there is major or minor motion. Applicable for retrofit use with concrete or inaccessible ceilings which limit access to low voltage wiring, new construction with line-voltage circuitry only. Maximum reliability and minimum false triggering. Ability to customize settings for room size and environment by use of dip switches. Sensor can easily be adjusted to meet the needs of the room occupants by use of dip switches. Excellent coverage of a wide area.
