How MAG turnstile DLAR techology help secure your entrance?

Do you know there is a loop hole inside common turnstile in the market? After a single user flash card, arm can be push forward and reverse freely to allow multiple users to pass through turnstile without flashing card. This creates a big security flaw at turnstile gate entrance.

The purpose of installing turnstile is to ensure only 1 person can pass through after each user flash card. This is important to ensure only authorized person can enter the building and access control system correctly capture the user access events. This loop hole has defeated the purpose of installing a turnstile at entrance.

MAG Tripod turnstile (TTS351L and TTS311) can solve this problem with our DLAR technology. DLAR is a Dual Level Anti-Reverse locking mechanism that prevents the arm to be reversed. The arm cannot be reversed upon reaching 15 deg and 30 deg of rotation. The only way is to rotate forward and pass through completely. DLAR ensure only 1 person can pass through at a time.


Following are Dual level anti- reverse (DLAR) lock feature in MAG tripod turnstile.


1st Level Lock First level anti-reverse lock at 15 degree. User is not able to rotate arm in reverse direction. User can only move forward.
