This won't help you with your alarm problem, but with your avionics/electrical systems experience, it might help with mine. I have a 1983 911 SC Targa, all original.
After being stored over the winter, the horn has started acting up. With the car parked, no ignition, the horn works.....all three contacts.
Start the car, and sometimes the horn works, sometimes it doesn't. Again, all three contacts.
The contacts on the steering wheel have been checked, clean as a whistle.
The horns are securely mounted, connections are all good.
Switched out relay.
The pattern here is............. ignition off, horn works perfectly. Ignition on, horn works perfectly. With the engine running, horn may or may not work.
Any ideas ?

hold the horn down while driving if it is not working , then go around a corner or round about and see if it comes to life, if soit could be the horn contactor behind the steering wheel. as you turn the wheel the horn sometimes works or doesnt.

if not that it could be the actual pick up ring or wiring mounted in the wheel
