Question W140 Alarm System Problem

Hello All,
I have a W140 600 (1992 model) and am seeking some help with a problem on the alarm system.

I am told that the car has a primary and secondary alarm. I can get into the car, that is the primary system unlocks all the doors, but when I open a door the secondary alarm system activates. The horn repeatedly sounds for about 2 mins and I cannot start the car.

Does anyone know where to look?? I have my MB tech looking at it but he has not been able to isolate anything. . He has hotwired the car to ensure there are no other problems.
