Product Overview
Collision Sentry Multi-Zone is a two-unit collision warning system for blind spots and conflict zones that are not limited to 90-degree corners. The paired units communicate wirelessly and can be positioned across passageways, on opposite sides of doors, or in other locations where traffic may approach from separate areas.
Each factory-preset unit is powered by included D-cell batteries and can mount magnetically or mechanically. Sensor vision is adjustable from 50 to 134 degrees, the units can be separated by up to 100 feet depending on the facility layout, and a Single-Zone mode allows each unit to operate independently when only one-direction motion detection is needed.
