Product Description

The Optex Quad Beam Photoelectric Detector, 350'/650' offers features to protect against false and missed alarms caused by mis-alignment and environmental issues. This photoelectric detector is ideal for mid level security perimeter applications and offers models that accommodate a 350 feet or 650 feet detection range. It features Quad beams to dramatically cut down on false alarms caused by birds and falling leaves. It also has a sniper viewfinder and alignment dial, which provides a high level of visibility for optical alignment work. And at long ranges, a perfect installation and stable performance can be achieved in minimal time.
