Airport Double Identification Speed Gate Turnstile

Airport Double Identification Speed Gate Turnstile

Product Description

This AB door is specifically designed for high security checkpoints such as airports and customs . The system uses an interlocking mechanism between two doors : when a person passes through the first door after access verification , they enter the passage . The second door also requires verification , and the system checks whether there is anyone inside the passage . The second door will only open when it is confirmed that the passage is empty ( meaning the first door is closed and there is no tailgater ) , achieving zero tailgating at a physical level and greatly enhancing passage security . The device has built in fault self diagnosis and alarm functions for easy daily maintenance . In emergency situations , it triggers fire mode , sounds an alarm , and automatically opens the gate . When power fails , the passage automatically opens , and it closes automatically when power is restored . It also features an audible and visual alarm ( immediate alert for unauthorised entry or tailgating ) , an anti crash function ( the swing arm automatically locks when no opening signal is received ) , and an automatic reset function ( if no passage occurs within 10 seconds after the gate opens , the current permission is cancelled ) . This AB door is an ideal choice for high security areas .

Features and Advantages

1 . Two door interlocking , zero tailgating

After the first door is opened with verification , the second door requires verification again and the passage must be empty before it opens , eliminating tailgating and meeting high security requirements such as those of customs and airports .

2 . Fault self diagnosis and alarm

Built in self diagnosis module triggers an automatic alarm when an abnormality occurs , helping maintenance staff quickly locate problems and reducing equipment downtime .

3 . Fire mode and power failure protection

In emergency situations , the turnstile triggers fire mode , sounds an alarm , and automatically opens the gate . When power fails , the passage automatically opens , and it closes automatically when power is restored , ensuring unobstructed evacuation and convenient recovery .

4 . Audible and visual alarm against tailgating

Unauthorised entry or tailgating immediately triggers an audible and visual alarm , effectively deterring violators and ensuring passage order .

5 . Anti crash locking mechanism

When no valid opening signal is received , the swing arm automatically locks , preventing forced opening by external force and blocking entry by unauthorised individuals .
