Turnstiles make an ideal solution for access controls with high levels of pedestrian traffic that need to both enter and exit the enclosed area and where space is limited. When users pass through the turnstile, the bars rotate allowing access to the enclosed area. The turnstiles can be configured for one-way (in either direction, blocking access from the opposite side) or two-way access. In emergencies, the automatic panic break-out bar is unlocked to facilitate evacuation.
