Ph2 IR central locking conversion to RF
#43
I think it is.. the connection from the wireless box is negative, so that goes to the negative side of the cap..

Yes, well without the resistor to quickly discharge the capacitor after disarming, the alarm arms again then for whatever reason the alarm was going off (could be some kind of tamper protection circuit triggering it). I found that the cap needed discharging quickly but not too quick, hence the experimenting with resistors and values...

Great shout on the cap though, I wouldn't have thought to use one straight away..

By the way, do you know anything about the sounder on these things? Mine's one of those type with 3 inputs and an internal battery.. It stopped working so I've rebuilt it, not fitted it yet though so don't know if it'll work...
