A motorized Gunnebo security portal with a transparent, elegant design for indoor and partially outdoor installation. The doors are always locked at rest — after authorization the first door opens, then closes once presence is detected inside, and only then does the second door open. Presence detection is included as standard; ultrasonic single-person detection, a contact mat or a weighing sensor against tailgating can be added as options. Throughput of 4 people/min, concrete foundation 1150 × 1150 mm. Also available as the HiSec² 6-Twin/6-SQ-Twin variant with two cabins in a single frame to save space (throughput up to 7 people/min).
