Infrared presence and motion detector

The motion detector LCN-BMI recognizes motion by thermal radiation emitted from the body. It is used for switching on various lighting (hallways, offices, toilets). Additionally, it can work as an alarm function in building surveillance.


The LCN-BMI is a PIR motion detector designed for use indoors. It  must be connected to an intelligent LCN-module. The sensor works according to the PIR principle (passive infra-red). It registers changes in thermal radiation due to human presence.
