• Product Introduction:

This product series comprises interior and exterior door leaves, a connecting passage, an electrical control system, and mechanical-electrical locks, offering a certain degree of resistance to vandalism. It is designed to segregate controlled areas from uncontrolled areas, thereby preventing unauthorized individuals from following others into restricted zones, and is primarily used at the entrances and exits of operational areas in the banking and financial sectors. The anti-tailgating interlocking doors are manufactured from high-quality steel or 304-grade stainless steel; the inner and outer door panels have a thickness of 1.0 mm, while the door frame is constructed with 2.0-mm-thick steel plates. The door core incorporates a reinforcing framework and sound-absorbing filler, and the inner door is fitted with a 175×235-mm transparent viewing window. The locking mechanism is installed as a flush-mounted unit, with reinforced protective steel plates at the mounting location. Once the door is closed, the latch engages and locks, featuring a positive-locking function to prevent prying or forced manipulation of the latch. The connecting passage shares the same structural design as the door leaves, with a net internal depth of no less than 1 meter.

• Basic product functions:

Interlock and interlocking function: When the interlocked doors are in normal operating condition, once either the inner or outer door is opened, the other door cannot be opened by either mechanical or electrical means.

Timeout activation prompt function: When either door of the interlocked door system remains open for more than 10 seconds, the electrical control unit will issue a corresponding alert.

Emergency Unlock Function: In emergency situations, both the inner and outer doors can be opened simultaneously, and the electrical control system will immediately trigger an alarm. After the electrical control system is reset, it will automatically revert to the interlocked, coordinated operating state.

Emergency Locking Function: It shall be capable of emergency locking both the inner and outer doors; once emergency locked, neither the mechanical nor the electric control system shall permit normal opening of either door, while simultaneously triggering an alarm. Upon reset, the electric control system shall automatically revert to the interlocked, coordinated operating state.

Emergency Activation Function: When the electric control unit of the anti-tailgating interlocked security door malfunctions, manual operation is available to enable emergency dual-door emergency opening and dual-door forced reset functions.

Information recording function: Card-swiping door-opening/closing record storage function, with a capacity of 100,000 records and a circular overwrite feature.

Technical Standards: This product series complies with GA 38-2021, the Bank Security Prevention Requirements, and GA 576-2018, the General Technical Requirements for Anti-Passback Interlocked Security Doors.
