Answer:
The turnstile incorporates a positive action lock to prevent two passages per authorization and an anti-backup device that blocks reverse rotation once the rotor head advances 30 degrees past rest. Both the structural frame and rotor assembly are fabricated from SS304 stainless steel.
Engineered for perimeter security and high-throughput perimeter checkpoints, the KTI0201703MK1SS integrates mechanical safeguards against tailgating and reverse forced entry:
- Positive Action Lock: Mechanically secures the rotor immediately after passage initiation, preventing multiple users from squeezing through on a single authorization signal.
- 30-Degree Anti-Backup Mechanism: Engages automatically as soon as the rotor head advances 30 degrees from its resting detent, eliminating the possibility of reversing direction mid-transit.
- SS304 Construction: Built with an SS (SS304) stainless steel frame and stainless steel rotor assembly for resistance to demanding operating environments.
- Smooth Mechanical Centering: A built-in mechanical self-centering system ensures the mechanism reliably and silently completes each cycle back to rest.
