record AIS 290 – active infrared presence detection sensor
When analyzing its immediate environment, the record RAD 290 motion detector permanently communicates with the control device. The detection field is defined electronically, allowing it to eliminate previously acquired door movements. Time-consuming mechanical fine adjustment of the sensor is thereby eliminated. Also, changes to the field due to temperature differentials are largely uncritical.
The record RIC 290 sensor device uses microwave and active infrared technology. It is equipped with both a combination of motion and presence detectors that trigger opening and closing operations with a high level of security and reliability. The device actively communicates with the door control, and recognizes persons in the passage area. A light curtain also prevents collisions with the door leaves.
