Private conversation
In video intercoms the private conversation feature
is permitted by the jumper J1 (position 2-3)
located on the fixing bracket. In intercoms you must:
- insert the private conversation module art. SM50;
- to cut the jumper W1 that links the terminals 3 and
7.
- move the connection of the buzzer from terminal
3 to 7.
- make the connection between terminal 7 of the
intercom and the - (minus) of the privacy module.
Cut the resistance R1 in all of the privacy modules.
