The THT-100MD is one of the enhanced full height turnstiles offered by AVL to meet specific security applications where the safety and security of metal detection is required. The fully integrated systems combines aesthetic appeal with real control for installations demanding accurate and efficient monitoring of persons carrying metal objects. Electrically controlled in one or both directions, the turnstile is capable of interfacing with any type of card reader access or biometric system.

The THT-100MD is especially well suited to airports, schools, precious metals factories, courthouses prisons and military bases. The THT-100MD is equipped with 2 key operated modes of operation. The first allows authorized users free passage through turnstile unless a metal object is detected. When notified by the integrated metal detector, the turnstile locks and bars passage until the violation is resolved by security personnel. The second mode integrates an access control system into the turnstile and allows one at a time entry to authorized users through the access control system. If an alarm condition occurs, the access control reader is shunted and the turnstile remains locked, barring entry until the violation is investigated and cleared.
