Photobeam detectors are ideal for covering a large area or an open area where you want to be alerted to someone or something crossing a threshold. For example, perhaps you want to cover a set of windows, or the end of a hallway where there is no door. Anything breaking the beam of the detector strips the sensor.
These indoor photobeams are designed for easy installation and superior reliability.The AX-100S mounts directly to a single gang electrical box for easy installation in prewire or retrofit applications. The sensor features special optics that eliminate the need for vertical adjustments and an LED alignment indicator. Indoor photobeams detect blockage and are excellent for rooms not suited to PIR detectors.
