On the hinge side, the infrared safety sensor will interrupt the automatic movement of the door when- ever it detects an obstruction;IRS-4 active infrared safety sensorDORMA IRS-4 IRS-4 safety sensors are excelled by their easy com- missioning and adjustment. The sensors’ monitoring quality within the driving path depends on the condition ofthe floor in the close range of the door system. IRS-4 sensors are suitable to monitor standard floors and floors with low reflectance levels, gratings or floor mats.
