Installation
Recommended alignment technique is to mount the NIR-50 at the desired location and hold reflector
about 2 or 3 feet in front of the unit and while watching the lights to assure that both remain lit, move
backward to the desired mounting location for the reflector. You may have to move the reflector up,
down, left or right to keep the reflector in the middle of the signal path. This assures the least
troublesome set up by keeping the reflector off the edges of the signal where any movement may take
it out of alignment. Note: the signal pattern is only 2 feet diameter.
