All the PIR’s I have come across have NC contacts
Trip the device and it goes open
circuit
Having said that I’ve always been able to get into the units
and they
are normally marked
Your colour code seems to follow the normal standard
though
Not too sure where your +ve is coming from
Andrew Roberts on the Comfort news group is always a good guy to ask

Subject: [ukha_d] PIRs onto
HV.
I
am
just trying to rig a couple of PIRs onto HomeVision to get it to turn some
lights on when I walk into my computer room ... the PIRs have 6 terminals.
(Blue, Yellow, Red, Black, Green and White).
Green
and White are intrusion contacts which break when the unit is
dismantled.
Red
and Black are +V and 0V respectively.
Blue
and Yellow I assumed would be a set of contacts which either make or
break when the PIR trips ... however it seems that Blue and Yellow are
commoned together and when the PIR trips they are connected to
+V.
Is
this right and if so then how do you connect a security system PIR to
HomeVision?
Cheers
Phil
