Infrared Barrier Doublebeam

The infrared barrier "doublebeam" was conceived for indoor and outdoor use. Each unit contains a parabolic mirror that transmits/receives 2 ir beams. Only when both beams get interruptet at at the same time an alarm will be reported. So false alarms due to falling leaves, small birds, insects, etc. Are reliably prevented. The attractive housing with a parallax-free facetted cover conceals the most modern technology available. Freely rotating optics and various adjustment tools(included by default) allow simple alignment.Key features:- insensitive to direct sunlight radiation- long range both indoors and outdoors- time-saving installation- simple alignment- adjustable alarm response time- weatherproof casing- alarm memory- integrated fog detection
