Overview

The SR-MDS is a radio multi-sensor that measures light level and detects motion. It is normally fitted to the ceiling and powered at 24 V, so it keeps working in rooms with little light such as basements. The BAT model uses LS14250 batteries instead. It has a passive infrared sensor with a 360 degree range, about 5 m across at 2.5 m height. It sends EnOcean telegrams at 868 MHz or 902 MHz, immediately on movement and otherwise every 10 to 1000 seconds depending on light changes. It is built for constant light control applications.
