Turnstile allowing emergency exit whilst encouraging presentation of credentialsTurnstile comprising a barrier 1, 2, motor 7, 8, brake and credential checking means. If an exiting user presents a credential the barrier opens to allow exit, and if the user does not present a credential, and an authorised person is not detected attempting to enter, the brake is unlocked but the barrier is not moved, so that the user is able to push or pull the barrier open, with the motor acting to cause the barrier to move more slowly than it would if the user had presented their credential. This delay factor encourages users to present credentials whilst still allowing non-authorised exit in case of emergencies. The turnstile may detect whether other users are following the first user in the exit direction, and keep the barrier open until no more are detected. There may be a crash switch 20 for causing the barrier to unlock, which may be enabled only when a person is detected attempting exit. The presence of users may be detected by electrical and/or optical sensors, which may comprise a row or array of optical sensors 12. The means for checking credentials may comprise a card reader 14 and/or biometric sensor.
