    Hi everyone,
    I have wired magnetic opening sensors connected and working in the home burglar alarm. Today I tried to add others without being able to detect them.
    Up to now one sensor on each zone (gives 1 a 8) 1 contact on GND e 1 with resistance 6,8 K alla zona.
    They are 1 zone I put two in parallel each with relative resistance (6,8 K) the control unit not only does not detect the one just added but not even what worked before.
    Someone can tell me if it's a resistance problem or something else?

    thank you


    You tried to put the sensors in series leaving the resistance only on the first sensor?

    I tried.
    Edge Zone -> resistance-> clamp . Signals the opening (all normal)
    I add:
    Zone B Filo -> clamp does not read either opening of the two. However, it signals the closure of Zone B.



    Mi sembra che la resistenza non dovrebbe essere superiore ai 6k8. Come dice Amilcare ti rimane il valore richiesto e se uno dei due si apre ti segnala, ma ovvio che non si può determinare quale dei due.
    Quindi avresti una uscita che collega zona A e di seguito zona B che collega a massa.
