Heavy winds, extreme temps no problem for parking bay security door

MAXIFLEX recently installed a security door for the underground parking bay at an upmarket student apartment block.
Maxiflex Managing Director Bram Janssen said the bay at My Domain in Cape Town houses approximately 60 vehicles. “Our RR3000R high-speed door model from the Assa Ablot stable presented the ultimate heavy-duty security solution for this application,” he said.
“The high-performance door perfectly combines aesthetics and style with reliability and security to fit in with My Domain’s modern architecture. In addition, the rugged door effortlessly meets the demands typical of a high traffic area, reliably operating at very high cycles per hour ensuring that the safety of the students is maintained.”
The door is fitted with an MCC frequency converter control that aids high opening and closing speeds of up to 2.0 / 0.6 m/s and a quiet, low-wear motion sequence.
Clear window slats are incorporated into the door curtain, which give students a clear view of the outside to detect any possible threats. Other safety features including a contact-free pre-running safety photocell and a door line photocell that prevents the door from closing when there are people or objects in the closing plane.
Janssen said the door’s dimensions of 6000 x 3000 mm made it ideal for use in locations where reduced space is required over the lintel. It features self-supporting galvanized steel-edged side frames. The door’s anodized aluminum lamella door curtain is connected by flexible wearless heavy belts that wind up without contacting each other, contributing to an extended life cycle.
“These unique design features deliver an extremely long service life coupled with low maintenance needs,” he said.
During a power failure the door can be opened manually with the brake release handle by a spring system in the side frames. With class 3 - 4 (EN 12424) wind resistance, the high-speed door is unaffected by Cape Town’s notoriously strong winds, Janssen said, adding that the door is also able to operate hassle-free in extreme temperatures ranging from −20°C to +60°C.
