Code 3 Mastercom-B Siren

I was able to obtain this siren from someone who had a whole bucket load of it. I haven’t had a real use for it except using it as a tornado siren.

Moment when my drink spilled onto my code 3 Mastercom and now the green like is constantly on when the car is. Any suggestions?

My guess is that your Mastercom-B must be shorted out. Maybe the liquid got into the unit and make contact with a small chip that sends a current to a certain part that plays the tones. I have several more Mastercom-B's at a place.

It might be the microphone?
