Anonymous users2024-01-24If it keeps ringing, it means that the switch that presses the doorbell is short-circuited, that is, it is a state that someone has been pressing, or the switch cannot be bounced when it is pressed. Can't talk to the problem.,If your doorbell is short-circuited, it is estimated that other functions will not be normal.,Now do a good job of the problem of ringing all the time.,See if there are any other problems.。。

Anonymous users2024-01-23Look at what your intercom is like, if it's hands-free, then see if the answer button is broken, but you can't answer, because you can't answer, so you may not be able to open the door.
If it's a handle, it's possible that the fork spring is broken, so you can replace it.
Of course, it is also possible that the call line from the extension to the host computer is broken! Because a lot of intercom transmits the unlocking signal through this wire.

Anonymous users2024-01-21The security door of my unit can be intercom but cannot be opened with a walkie-talkie, what is going on? Thanks for the answer.
Not necessarily the door is broken! Generally, there is a small pimple on the inside of the security door, and if you twist it, the key on the outside will not be opened. It's the last level that locks it. >>>More
There is a special unlocking and door-to-door service, but it must be approved by the Public Security Bureau and guaranteed.

There are the following problems; 1. Line 2 power supply 3 head failure.
Some of the keys are not very accurate, I had one before, and after opening the door, the original key could not be opened.
