Hi
Czy wszystkie 21102 z 99 maja taki sam alarm?
Jezeli tak to jaki bo mi syrena niedziała.
i szukam schematów

Pozdrawiam

In english, please. I don't understand.

I asked whether all 21102 from 99 they have the same alerts, for me a siren isn't acting (has 4 wires) and I don't know how to connect second, I am searching for also schemes and I don't know how to check the model
