964 alarm

[rich 36]

My car came with an after-market alarm fitted (probably UK) since imported mid 90's

I've not been able to successfully lock/unlock it on the fob without it waking up the neighbors
un prompted in my absence

I only carry the fob at all, since he immobilizer is triggered from it on start-up.

without using the A/M and opening engine cover say, the horn sounds but not A/M

does this mean the Porsche fitted alarm is still operational, and don't alarm fitters disable them usually


I mean is it common to have alarms working in parallel?

mine does. alarm on fob, porsche alarm if i use the key.

Which I suspect mine should also, however it locks OK on fob but mor often than not an hour or so later it goes off for no special rason although windows are closed etc and nobody rocking it at all.

I wonder what might need adjusting

[wildoliver]

which alarm goes off the porsche one (horn) or the aftermarket (siren)

Siren (clifford BTW)

came out Yesterday and re-soldered a dry joint,

he was saying that depending on installers mood,
often sees both factory, and after market systems working in tandem.

All mine was doing on fob/disarm was not sending a clear voltage signal to the door solenoid
and this was setting off the P-alarm fitted

anyway all seems in order now
