I'm not sure how the electronics of the air system works, but I have
interfaced my Alpine 8080 alarm to my hydraulic doors. Yes, that's right. I
did say hydraulic doors (Terry doesn't read any of this, does he?!).
The hydraulic doors are more complicated than the air system I imagine would
be. The hydraulic doors need constant high current for the duration of the
door travel and need limit sensing to cut off the power. I replaced the
original pump/reservior with two new pump/reservior units that I got from a
company called Hypac. They look exactly like the original except they have a
release valve that returns fluid to the reservior when the door reaches its
limit. I used a power window add-on module for alarm systems called
Twindows from MicroElectronics. These modules "hold" the switch for me with
a trigger from the alarm brain (via the remote) OR a tap on the existing
switches. The Twindow "sees" the drop in voltage when the door reaches fully
closed and cuts the power. For the door open limit I had to fabricate a
limit switch to trip a relay which tripr the Twindow off.
I did all of this before I knew of the club or the air doors. I did it as an
engineering challange so the doors can be safely operated without
overdriving them or burning out the pump (the doors can now be run in
oposite directions simultaneously).
I know this probably doesn't help too much. The air door system probably has
it's own issues, but I'm sure it can be done safely. If you're not
comfortable designing an interface yourself, I suggest you go to a reputable
car audio/alarm store that is known for their custom installs. They will be
prepared to handle the quirks that come up in a custom job like that.
Hope this helps
