Hello, good morning I have a problem with a central alarm dsc pc5010 the problem in question is that I was doing maintenance and had to factory reset since I did not know the installer code. Well I had to program everything from scratch. There are only connected smoke sensors, I have seen in some cases that only connect the cable from the area to the terminal of the area on the card but not to the common. Can it be done like this or not? And as would be done there would be some programming help please!

You can also use the negative of the Plate that is unified with the common zone

The solution was to use a wire that linked all the zones and connect it to any common plate
