It is aimed at criminals who use trailing or coercive methods to enter the business hall for illegal activities, and specializes in research A kind of access control security controller.
Bank anti-tailing (double-door interlocking) access control system solution
2. Detailed explanation of several main functions
1. Linkage (or double door interlock) function: if one door is not closed, the other door will never be opened
For example: the outer door is not closed, the voice prompt: please close the outer door, the password keyboard reader or exit button of the inner door is invalid, and the door cannot be opened; the system must wait for the password keyboard reader or exit button of the inner door after the outer door is closed. Only with a response can the inner door be opened.
On the contrary: the inner door is not closed, the voice prompt: please close the inner door. The password keyboard reader or exit button of the outer door is invalid and the door cannot be opened; the system must wait until the inner door is closed before the password keyboard reader or exit button of the outer door responds before opening the outer door.
2. Anti-tailing (or duress alarm) function, each card reader can alarm
1 set of clear alarm password: enter the clear alarm password, the system will output a clear alarm signal (that is, the clear alarm relay is activated), and both doors will be locked at the same time when an alarm occurs! This alarm can only be released by the linkage key of the indoor 5-key keyboard to make the system return to normal working status.
1 set of dark alarm password: input dark alarm password, the system will output dark alarm signal (ie: dark alarm relay action), both doors will be locked at the same time when alarming! This alarm can only be released by the linkage key of the indoor 5-key keyboard to make the system return to normal working status.
3. Illegal user alarm function. If there are 5 illegal users in a row, the sound and light alarm will send out an alarm signal, and the system will automatically lock for 5 minutes, then return to normal, or use the linkage key to return to normal.
4. The voice prompt function prompts the user: the outer door has been opened, the inner door has been opened, the door has been fully opened, the door has been fully locked, please close the inner door, please close the outer door and other door status information.
5. Channel light control, the power of the external channel light is less than 400W, it will light up when the door is opened, and it will automatically go out after one minute.
7. Emergency braking (double doors fully locked) / double doors fully open function.
8. Special functions of five buttons (five-key keyboard)
Fully open: Press the full open button, the system will make the two doors in a fully open state. Voice prompts the user: the door is fully open. After the two doors are opened for 5 seconds, it will automatically reset, and the system will return to the normal working state (if one door is open, the full open key will also work).
Full lock: Press the full lock button, the system keeps the two doors in full lock state. Voice prompts the user: the door is fully locked. When the two doors are fully locked, the password keyboard of the outer door, the inner door, and the exit buttons beside the two doors are all disabled, and the two doors cannot be opened. Only through the linkage button to release, the system returns to the normal working state.
Linkage: Press the linkage button to make the system return to the normal working state from the full lock function state, the illegal user alarm function state, and the full lock state after the duress password alarm (open or dark password alarm).
Open the inner door: press the button to open the inner door, and the user will be prompted by voice: the inner door has been opened. (It is equivalent to the exit button of the inner door, which must be linked, that is, when the inner door is opened, the outer door cannot be opened)
Open the outer door: press the button to open the outer door, and the user will be prompted by voice: the outer door has been opened. (It is equivalent to the exit button of the outer door, which must be linked, that is, when the outer door is opened, the inner door cannot be opened)
Note: The above door open refers to the state of the door lock, not the state of the door
9. There are many ways to open the door: ①Swipe card, ②Password, ③Swipe card+password, ④Card or password, ⑤Exit button.
10. Initialize the management password function
Initialization method: There is a reset button on the controller main board (see the hardware wiring diagram), hold it down before powering on the system, and the system is powered on. After the three lights on the system mainboard flash at the same time for a few seconds, the mainboard buzzer will sound once, and the keys can be released to complete the initialization of the management password. The management password after initialization is: 88888888;
12. The unlocking time is 5 seconds when leaving the factory, which can be set by programming; after the user’s identity is confirmed, the door lock opens for 5 seconds and waits for the personnel to open the door. The system voice prompts: the inner door has been opened / the outer door has been opened.
13. The door sensor alarm time is 5 seconds before leaving the factory, which can be set by programming; the door is locked 5 seconds after the door is opened, but if the door sensor detects that the door is not closed, the system prompts: please close the inner door/please close the outer door.
