This reliable turnstile is especially suitable for applications where high flow rate, and easy installation is required. In the event of a power failure, the arm instantaneously drops. Once power has been restored the turnstile will revolve to re-set the arm. Manufactured from high grade 304 stainless steel this tripod turnstile comes with an ultra-reliable mechanical head mechanism giving unprecedented years of service. After each passage the barrier arms are automatically returned to home position. The arm rotation sensors track passages through the turnstile to ensure accurate count outputs to access control systems or optionally fitted counters. The turnstile is operated from the logic board fitted inside the housing and can be easily integrated with most access control devices such as: card readers, coin/token acceptors, ticketing systems, etc. There is also a dedicated fire alarm input.
