The OA-203 is an active infrared motion & presence sensor designed for use with any manufacturer's automatic door as add-on safety or side-light protection sensor. The OA-203 may also be used on single and double pair swing doors, bi-fold doors, low-energy power operated doors, drive-through windows, vestibule, or anywhere with limited approach requirement
With Activation and Safety detection in one unit, OA-203C is two sensors in one. Fast installation and service, and laser-sharp Active Infrared Technology are just a few of OA-203C's benefits. Its versatile detection area solves problems caused by narrow vestibules and 'ghosting' and provides additional safety or side light protection.
