The 3-plastic-Fresnel-lens optical system permits the formation of three optical axes. This results in a broad observation band for the observer, even if perception is indirect (reflection on walls). The advantage of the 3-lens optical system over mirror beacons and flashing beacons arises in the case of atmospheric disturbances such as mist, smoke, fog and snow, and also in the case of direct solar radiation.

The mini-tri-lens optical system combines all positive features of the flashing beacons and rotary mirror beacons. It achieves an excellent short- and long-range warning effect. Blue and amber light is signalled as "blue" and "amber" even at large distances.

These beacons of the KL type series are a special PINTSCH BAMAG product. The optical system consists of three 60mm-dia. aspherical condenser lenses whose horizontal axes are offset against one another by 120° and whose vertical axes can be inclined upwards or downwards for special applications.

Electronic flashing beacons to warn of hazardous areas, mark building sites, safeguard work sites in industrial plants, and mark container-loading plants.

Warning of hazardous areas, marking of building sites, safeguarding of work sites in industrial plants, and also the alarm system sector are only some of the applications in which these electronic flashing beacons are used. Lightness, operational reliablity and compactness of design are typical features of these beacons.
