MULTIBEAM LENS DATA
The GJD multifunction lens tted to the GJD Opal XL detector produces 9 long range beams and 9 medium to short
range curtain beams. Movement across the beams produces the best response and range, whilst movement towards
the detector will be less responsive.
When mounting higher than boundary fences rotate the module and mask off any beams, either vertically or
horizontally, that fall outside the area being covered. Use portions of the self adhesive silver mask supplied to the
rear, smooth side, of the lens and always replace the correct way up as shown to obtain the exact beam pattern
coverage.
