DDS-A hybrid movement and presence switch

The DDS-A hybrid switch is a sensor that combines active infra-red (AIR) technology to protect pedestrians with microwave technology to open the door.

One-way and supervised, it detects the movement of approaching objects so that the door closes more quickly and remains open for less time. It also detects obstacles to ensure the highest safety level and making it suitable for emergency exits. Its installation is recommended for indoors and outdoors on Manusa doors compatible with Visio Range operators.
