Double-sided spike barriers control access

Residential Estate Security Handbook 2020 Access Control & Identity Management

Umthunzi Valley in Carlswald, Midrand, offers a variety of secure residential apartments for discerning homeowners. Ideally located with easy access to Midrand, Waterfall, Fourways and Centurion, the development encompasses 215 luxury lifestyle apartments with luxurious appointments.

State-of-the-art security and access control, together with open spaces, beautifully landscaped gardens and a multitude of amenities provide the ultimate living experience. In an effort to augment the access control aspect, Turnstar supplied four Velocity Raptor automatic tyre spike industrial vehicle barriers.

The Velocity Raptors have been installed at two entrances and two exits, each with one visitors’ and one residents’ lane. The barriers are powder coated in charcoal blue to complement the upmarket ambience and contain an integrated optic LED light strip for maximum visibility, safety and aesthetics.

The fit-and-forget Velocity Raptors at Umthunzi Valley feature a double-sided spike that provides the maximum illegal ingress and egress vehicle prevention. The barrier arm and spikes are driven by two separate motors and the three-stage interlinked opening and closing procedure prevents mishaps occurring when a vehicle drives underneath the barrier arm before the barrier arm is in the raised position and before the spikes have lowered fully.

“In essence, the opening procedure is: the spikes lower, the barrier arm raises and the optic LED barrier arm changes to green. The closing procedure entails the optic LED barrier arm changing to red, the barrier arm descending and then the spikes rising. The Velocity Raptor is a good choice for safety-conscious homeowners’ associations with its intelligent collision detection, mid cycle auto-reverse, safety loop and infrared beam system. In addition, the built-in battery backup allows up to 1500 operations in the event of load shedding, with a manual override ensuring continuous operation once the battery power is exhausted.

“Added to these features is the fact that the high-speed operation of the Velocity Raptor means that less bottlenecking occurs, which is especially useful when large volumes of residents are departing for work at the same time,” says Craig Sacks, managing director of Turnstar.
