Today we will talk about how to open an intercom. But before that, it is worth noting that universal passwords for all devices do not exist. Each manufacturer sets a specific code only for their device. For others, it is not suitable.
How do you know the coveted combination of intercom? If the installer did not consider it necessary to change the master passwords, the following instructions will help you do this. If they were changed, then to get the code you will need to contact the device service department.

Then we try the following codes: 65535, press the button to call, then 1234, press the button to call along with 8. The second option: 1234 with the call button, then 6 with the call button and 4568.
And a few words about how to open the intercom model "MK-20 M / T" of this manufacturer, without performing any manipulation of the keyboard. She did not and will not have as such a system of protection against the use of master keys. Therefore, when you bring the so-called “tablet” without firmware to the doorphone reader area, the device will automatically enter the programming mode. If you don’t have a tablet, you can make it open using the numeric keypad. To do this, enter the following combination: call button, then 27, again the call button and 5702. Or this: the call button along with 1, again the call button and 4526.
Now about how to open a VIZIT intercom. Here you have to sweat due to the wide variety of models. Each of them has its own combinations. Very often there are no * and # buttons on the keyboard, and instead of them are the "C" and "K" keys, respectively.
If the standard settings of this doorphone have not been changed by the installer, the door should open when you enter the combination * # 4230 or 12 # 345. Visit devices can also be opened using the code * # 423 or 67 # 890.
How to open the doorphone of this company through the service menu? We dial # 999 - this will enter the control menu. Then we wait for two short signals, after which we enter the master code. The default is 1234. This intercom should respond with one short beep. If the code is incorrect, the signal will sound two-tone. Then you can try to apply other standard options for master codes - this is code 6767 or 3535, 9999 or 0000, a combination of 12345 or 11639.
When you enter the service menu, you can both open the intercom and do some other operations. Press 2, then pause and press #, wait a while again and dial 3535. This will open the door without a key.
Button 3 makes it possible to program a key for the intercom.
