The DH17i is a high mount 4-row selectable motion or presence sensor designed to provide either activation or safety protection for industrial doors. The DH17i is based on the most reliable active infrared (AI) technology available—Floor Reflection Method (FRM). With FRM-AI up to 24 individual detection zones (floor points) are precisely reflected off of the floor in a rectangular pattern. The DH17i provides motion or presence detection as far as 20 ft. (6m) from the door and mounts between 10 ft. (3m) and 20 ft. (6m) off the floor. It is an ideal alternative to in-ground loop detectors.
