Quick answer

Turnstile faults usually come from power, a reader or controller that isn't sending the open signal, the fire alarm input holding the lane in free mode, or a mechanical problem such as a worn solenoid or misaligned flaps. Check power and the reader before suspecting the mechanism.

03Frequently asked questions

Why do my turnstile arms spin freely?

Usually the fire alarm input or a power failure has put the lane in free-passage mode, which is a safety feature.

Why doesn't the card open the turnstile?

The card may not be enrolled or permitted at that time, or the reader isn't communicating with the controller.
