record AIS 290 – active infrared presence detection sensor
The record AIR 290 is an active infrared sensor that generates a narrow light curtain reaching to the floor. The opening impulse is triggered when an object enters the light curtain. This sensor is particularly suitable when only a small field of detection needs to be covered.
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.
