Zebra-425,8-B fan intrusion detector

The detectors are used for protection of separate perimeter sections, where the use of two-position detectors is difficult or impossible, for example, dead ends, swampy areas, ravines, fence crossings, storage areas, tunnels, overpasses, overpasses, etc. The main distinguishing feature of ZEBRA-42(5,8) detectors is the operating frequency of 5.8 GHz, which provides the detectors with the following advantages: <ul> <li>- insensitivity to atmospheric precipitation (rain, snow);</li> <li>increased resistance to the presence of grass cover (the permissible height of the cover is 0.3 m);</li> <li>increased resistance to the presence of individual plants up to 0.5 m high;</li> <li>increased resistance to vibrations of the support</li> </ul>
