ARCS – Access Rate Control System

The Access Rate Control System (ARCS) system is a fully mechanical, ready-to-install kit that controls the speed of a person’s entry through full-height turnstiles. The faster the entry speed, the more resistance is generated by ARCS on the rotor to slow the operator. At a preset normal entry speed, the operator can pass through with minimal rotor force, and ARCS freewheels on exit. All internal components are furnished in a weather-protected steel housing. This low-cost kit can be installed quickly on new or existing turnstiles, cost-effectively providing a new layer of security.
