Active Infrared Sensor Technology
Combined Technology Sensors
Capitalising on the merits of both infrared and microwave technology.
Combined technology sensors, like the SSR-3, look to capitalise on the merits of both infrared and microwave technology by combining both into one sensor.
The microwave part of combined technology sensors (shown in blue below) allows for the detection of a fast moving traffic or pedestrians at large distances from a door, thus ensuring timely door opening.
The unidirectional detection nature of microwave sensors also decreases door hold open time, thus reducing building energy losses.
Microwave technology’s lack of safety properties is overcome by the addition of a three-dimensional infrared safety curtain to protect pedestrians from contact with a moving door.
