From the manufacturer's datasheet for RDF-IR RS485 BACnet.
Overview
The RDF-IR measures an averaged radiation temperature over a circular area on the floor or workplace from a ceiling flush box. It uses an infrared sensor with an optical aperture of 80 degrees +/-5 degrees. It suits rooms, offices and other workplaces. The Dual version uses two IR sensors and can output the mean, minimum or maximum of both. The sensor head connects by patch cable with RJ45 plugs, 1.5 m on the listed parts, to a USE-M enclosure with BACnet MS/TP and 0 to 10 V outputs. An LCD is an enclosure option.
