Microwave sensors will detect forklifts as they approach crosswalk and flash LED's in the floor strips to warn pedestrians and forklift drivers they are approaching a crosswalk. They will not activate on pedestrian or forklift traffic that is leaving the area. Microwave sensors have an adjustable range up to 60 with an approximate field width of 12' at 50'. The sensors should be mounted 6' above pedestrian traffic to avoid activating on pedestrians. The system is low voltage powered by a 24VDC 70W switching power supply that is plugged into a 120VAC outlet located within 100' of the sensor.
