A locking turnstile denies access to unauthorized personnel via an electronic locking mechanism. Locking turnstiles contain a solenoid to control locking and unlocking of turnstile barriers electronically. Unlocking the turnstile can be triggered by card readers, access control programs, or push buttons.
Many types of turnstiles have locking capabilities. All full height turnstiles and waist high tripod turnstiles can be equipped with locking mechanisms. A locking turnstile can be configured to have free entry/locked exit, locked entry/free exit, or locked entry/locked exit depending upon security needs.
