    Hi my alarm, Spc 43xx went off for apparently for no reason. Digging deeper i found that 2 contacts on velux windows, which are on the same line is were the strange problem appears. When looking at the input log of these i get weird ohm readings and only at certain times. I am posting the logs if anyone has any idea whats up. I havent opened velux windows in a while and the last part of the log u can see when i open/close the windows. 14 hours later and nothing is happening. Are the contacts not working or else?

    Could be anything on that zone. A faulty device or a bad connection or damaged cable.
    Have you a meter to check the resistance properly?

    If so proceed as follows:

    Disconnect the zone from the panel & remove any end of line resistors,
    Set you meter to continuity (200 ohms) and connect the pair to the 2 meter leads.
    on a length of cable long enough to reach all your windows on zone 3.
    Make a note of the reading in ohms. One by one tap every sensor & open and close every contact. After a tap or an open close the resistance should return to the around the same value. If it does not disconnect that device , close of the pair wired into it & move on. Replace any that you had to close off.
