INSTALLATION RECOMMENDATIONS ACTIVE INFRARED BARRIERS VIRTUAL BARRIER INTRUSION DETECTION STATUS & MAINTENANCE OF THE MONITORED ZONE In order not to disturb the infrared beams and ensure the smooth operation of external barriers, it is important to take into account the site environment and remain vigilant on: VEGETATION: the zone between the infrared columns must be completely free from obstacles. This involves cutting grass and pruning nearby trees THE CLEANLINESS OF THE CAPS: at least once a year, it is important to check the column caps, and if necessaryclean them using a soft, damp cloth. THE VIABILITY OF THE TERRAIN: prior to installation, ensure that terrain is really flat and columns will remain stable over time. Up to maximum 10º unevenness can be tolerated between columns. In case of unevenness greater than 10º, contact the SORHEA Sales Department. PROBLEMATIC ENVIRONMENT CORRECT ENVIRONmENT
