avantguard 4 intellistart necessary?

It's 12:30 at night and I need to get to sleep, DON'T use the existing dual zone unless you can get hold of a Clifford Digital zone sensor lV. I'll get back to you in my a.m. once I've looked at the wiring charts. Yes to skipping the tilt sensor.

thanks, you rock. it's 749pm here in Boston!

Scratch what I said about the 508d, try and get the Digital  Dual Zone Proximity detector part # 60-585 it works as well and it's easier to adjust. My own opinion is with that unit you need no other sensors. BTW I've got hard copy of the UK installation guide, or if you pm me with your email address I can download the US version and forward it on to you.

proximity sensors from the g5 product will work.  New part number same great sensor and you can find them pretty easily.  The only one that is compatible with ag4.  You could use your old dual zone shock on the new alarm as well in place of the omnisensor if you wanted to.  You wouldn't have dual zone though.  Orange on shock to orange of tilt sensor input.
