The PH line is a series of active infra-red barriers that is ideal for protecting large internal or external perimeter areas. It is made up of a barrier with max external range of 60 m and 1 double beam IR; by a barrier with max external range of 150 m and 1 double beam IR; and by a barrier with max external range of 200 m and 2 double beams. They can operate on 4 different frequencies selectable with dip switches, fi tted with high quality aspheric lenses and a box with gaskets which makes them ideal for external installations on a pole (brackets supplied).
