To improve access safety, Manusa offers two options: side safety infrared sensors, and movement and presence hybrid opening sensor. The side safety infrared sensor detects people or objects, and keeps the door in a safe position while they remain in the area of risk, even if they remain immobile. The hybrid safety sensor substitutes the standard opening sensor. It detects the movement of objects that approach the door, making it close quicker. Also, it keeps the door open when it detects a person or object, if these are located on the threshold of the door, even if they are not moving.
