    It seems that there is a bit of a conflict in your question: when you finish verifying your fingerprint or use the door switch to open the door, you can hear the normal unlocking sound, but the door cannot be opened: this situation is caused by the delay time of opening the door is too short.

    Your current delay time should be about 1 second, that is, even if the door is opened normally, but because the delay is too short, the door closes again before you can open the door. So, the phenomenon is that the door cannot be opened properly; After the door is closed, the electromagnetic lock cannot be locked in time, and it takes a while to lock: this is indeed a phenomenon caused by too long delay.

    Because the delay is too long, it may exceed the setting of more than 10 seconds, so even if the door is closed, the time from opening to closing the door has not yet reached the delay time (such as 10 seconds), so it is necessary to wait for a while before the magnetic lock can be re-engaged.

    Isn't it strange that these two problems happen at the same time? Did you delay the adjustment too much after the first problem occurred? If this is not the case, check whether there is a delay adjustment DIP on the magnetic lock, if so, adjust the DIP to 0 digits, and secondly, adjust the system delay to 3-5 seconds through software or all-in-one settings.
