Drop-arm optical turnstile, also called drop arm motorized turnstile,  is an effecient contactless crowd control solution for upscale corporate lobbies, high rise building entrances, luxury apartment complexes, universities, and anywhere autonomous entry and aesthetics are important. It adopts high-quality DC brushless motor and advanced positioning technology, ensuring the movement of security turnstile in a fast, accurate, stable and quiete way with low-noise, low-power consumption, and a longer service life; In addition, drop-arm motorized turnstile provides single directional or bi-directional access and easily integrate any access control systems or device with dry contact output.

How does a drop-arm optical turnstile works?
Drop-arm optical turnstile has a single passage barring arm which fully drop into recesses in the cabinet when opening and lift back into position to block the passage when closing. It is equipped with an array of sensors which provide a reasonably effective deterrent against multiple entries, and an alarm will sound when more than one person attempts to pass at a time or tries to come in the wrong direction. Drop arm optical turnstile usually integrates various access control system to customize turnstile access control systems, by which the pedestrians shows their valid credential before entry, the passage will be reased for free access, and automatically close after passage or out of passing time if pedestrians do not pass within pre-set time. In case of power failure or in emergency, it will automatic releases the passage for free access.

Characteristics of a drop-arm optical turnstile entrance system
1.Automatic Barrier Operation: drop-arm optical turnstile is a touchless turnstile equipped with DC motors which automatically drive barriers out of the way at requested direction to grant hand-free access, As hand-free turnstile, it must be able to function without any physical user input, and automatically open and close without any manual operation by the pedestrians
2.Proper Social Distancing: Though drop-arm motorized turnstile operates completely autonomously, it is usually for the organizations with turnstile access control systems at their entryways to have a security guard for providing assistance when necessary, it is crucial to ensure the employs are stationed a certain distance away from the touchless turnstile lane to maintain proper social distance.
3.Contactless Credential Checking: Although drop-arm motorized turnstile is completely contactless device, it is stile required to be integrated with a touch-free credential checking system to truly provide a hands-free entry experience. Some of these systems include iris scanners, facial recognition software, temperature sensors, and proximity scanners.

Can drop-arm optical turnstile be integrated with 3rd party access control systems ?
Off course,  drop-arm optical turnstile is comptiable with a wide variety of access control systems by dry contact. Card pass, fingerprint / handprint reader, face recognition, barcode reader, thermal camera and token applications can integrate with such access control turnstiles.

What will happen when power off and in emergency situation?
Drop-arm optical turnstile instantly automatically unlocks for free passage under emergency situations (power outages, fire, etc)

Can drop-arm optical turnstile be used indoor and outdoor?
Off course, drop-arm motorized turnstile is made for indoor or outdoor situations. For outdoor applications, there is should be shelter above.

Can drop-arm optical turnstile be operated manually or remotely?
Drop-arm optical turnstile is to be operated by the user at the turnstile. You can have a person who monitors the security turnstile from the surveillance terminal.
