I don't think the radio has an alarm. It has a flashing light to make you think it has an alarm, but it's just a code you have to enter after a power loss. At least that was the situation with mine.

My back windows have the stickers:
and my radio just has a code. But check your schematic for a connection to the alarm module.
Be careful: if you enter the wrong code 3 times you have to wait 8 years until you can try again.

It changes all the time
The radio has the alarm built in and not involved with the car alarm IIRC. The PO probably disconnected the alarm, because the stupid things sometimes go off for no reason, and nobody pays attention to them ayway. My daughter had a 300SEL and the alarm stated screwing uo while I was driving from my shop to home which is about 2 miles. I pulled away from the curb and proceeded to drive home with the horn honking and the lights flashing. I drove right by a patrol car, and it didn't even phase the RGs (revenue generators) in the car. The alarm should be in the right front footwell area and will say BECKER on it.
