I am thinking of having a pretty standard monitored alarm system and rather than try and make it pass events to a PC or HV I was hoping the signals could be split at source. 
 
What exactly are the issues with doing this via a single relay?

Mick

Mick,
 
Depends on the PIR.  Dual output ones aren't a problem - one relay to the alarm and the other to HV etc...However sharing the same relay for an alarm and HV isn't recommended unless the PIR switches a UL double pole relay.
Can I ask why you want to share a PIR?
 
Regards

Is there any reason that a PIR or other sensors cannot be dual wired to an alarm and another device such as a PC or Homevison?
