High Throughput Office Lobby Swing Gate Turnstile With Employee Attendance Anti Passback

Product Introduction

This swing gate turnstile is configured for the main lobby of office towers , business parks and corporate headquarters , where several hundred employees arrive inside a short morning window and the entrance also has to handle interviews , courier deliveries and client visits . The lane opens in 0.5 seconds , passes 30 people per minute in card mode and 40 people per minute in normally open mode , so a single lane clears the 9 am rush without building a queue into the lift lobby . Entry accepts IC and ID cards , employee QR codes , facial recognition , fingerprint and NFC phones , and every passage is written into the attendance log with time , direction and lane number , then synchronised to the HR attendance or payroll platform , which removes the separate clock in terminal at the door . Anti passback logic stops one badge being used twice or handed to a colleague , and four pairs of infrared sensors detect a second person following a valid entry with an audible and visual alarm . Visitor access is issued as a pre registered QR code or a temporary card with an automatic expiry time , so reception can admit a guest for a two hour meeting without creating a permanent credential . The controller provides relay , 12V level and 12V pulse interfaces plus RS485 or TCP IP communication , and can release the arms on a fire alarm signal or link to lift destination control and building management platforms . The cabinet is 304 stainless steel or 201 stainless steel with baked paint , the swing arm is acrylic , the mechanism is rated for more than 5 million cycles , and the anti pinch rebound force stays below 2 kg , which keeps the entrance safe in a dense commuter flow .

Product Features and Advantages

1 . Clears the morning peak without queuing

The swing arm opens in 0.5 seconds and the lane handles 30 people per minute in card mode or 40 people per minute in normally open mode . Employees walk through without stopping , so the 9 am arrival window does not spill back into the lift lobby .

2 . Attendance data without a second clock in terminal

Every entry is recorded with time , direction , credential type and lane number , then synchronised to the HR attendance or payroll platform . Staff no longer queue at a separate fingerprint clock , and HR gets one clean data source for lateness , overtime and shift records .

3 . Anti passback against badge sharing

The controller enforces anti passback rules , so a badge or QR code cannot be used a second time before the holder exits , and it cannot be passed to a colleague at another lane . Combined with face verification this closes the usual loopholes in employee access control .

4 . Managed visitor and contractor entry

Reception issues a pre registered QR code or a temporary card with an automatic expiry time for interviews , client meetings and maintenance contractors . Temporary rights disappear on schedule , so no permanent credential is created for a short visit .

5 . Building system integration and fire release

Relay , 12V level and 12V pulse interfaces with RS485 or TCP IP communication let the lane connect to access control , visitor management , lift destination control and building management platforms . On a fire alarm the arms release automatically to keep the escape route clear .

6 . Quiet , durable and safe in dense traffic

The 304 stainless steel cabinet , acrylic swing arm and mechanism rated above 5 million cycles are built for continuous commuter use . Operation stays low noise , four pairs of infrared sensors watch the whole channel , and the anti pinch rebound force remains below 2 kg .

Frequently Asked Questions

1. How many employees can one lane handle during the morning peak?

One lane passes about 30 people per minute with card or QR verification, and about 40 people per minute in normally open mode, which is enough for most single tower lobbies. Multiple lanes can be grouped on one controller for larger buildings.

2. Can the turnstile replace our separate attendance machine?

Yes. Each passage is logged with time, direction and credential type and can be synchronised to the HR attendance or payroll platform, so a separate clock in terminal at the door is no longer required.

3. What is anti passback and why does an office need it?

Anti passback prevents the same card or QR code from being used again before the holder exits. It stops badge sharing and one person opening the gate for several colleagues, which is the most common gap in employee access control.

4. How are visitors and contractors managed?

Reception or the visitor system issues a pre registered QR code or a temporary card with an automatic expiry time. Rights are removed on schedule and every visit is recorded with time and lane.

5. Can it be linked to our lift control or fire alarm system?

Yes. Relay, 12V level and 12V pulse interfaces plus RS485 or TCP IP communication allow integration with lift destination control, building management and fire alarm systems. The arms release automatically when a fire signal is received.
