Thanx for the info... Have been discussing this with several alarm installers. So far, ALL have indicated they are unable to do the Drivers door only...

I am POSITIVE there exists a means of doing what I want... Perhaps no-one has done this yet (other than to do as has been suggested, disable the vacuum source), but like I said, this is an issue of my daughter's security.

Any other ideas out there???

Thanx again...
