    Hello everyone.

    I have a Laskomex LM-8 intercom. But unfortunately it doesn't work. I moved into a newly purchased apartment, the intercom was moved to another place by "experts" who were carrying out the renovation. Perhaps there is a fault here.

    I can't find anywhere what should be on the terminals. I only found information that L- and L + are power contacts. Whereas Br is a contact for opening the gate. There is about 2V on the power supply, while between the L- and BR contacts 3V. It seems to me that the cables are wrong. What do you think about it ??

    Maybe some other reason ?? Apartment number set up correctly.

    Look for wires between which you will have over 6V and plug those in plus and minus. It may also be that the wires of the experts have shortened and the service has disconnected your apartment so that others can use the intercom. And let's call this variant optimistic, for now, let's stay.
    best regards

    Find the two wires with the highest DC voltage. Connect them to + L and -L respectively. Do not connect anything to the BR terminal yet. This is an additional option to open the gate (additional button).
    Has anyone tried to dial your apartment number? In digital systems, there must first be a call in order to then have a conversation.

    Thanks for the answer, everything works fine. It turned out that my wonderful specialists had incorrectly connected the intercom.
