You might be able to just disconnect the black 18pin connector on the Security System Module to stop the siren from randomly going off. This connector has the siren signal output. I have not tried this. I would but I dont have this problem and it's still raining.
MB's solution is to turn it upside down and put it in a bag.
This is fantastic information, thank you so much.
