alarm wont go off wile driving

[rmitch35]

Hi all, 1st time on this forum or any forum for that matter. My 06 thomas bus makes an alarm (buzzer) noise until the air pressure builds up to about 75psi then goes off.. but now another buzzer continues to make noise and wont shut off. I thought it may be the emergency exits, but to no luck! The only thing I did to the bus mechanically was removed the 2 passenger floor heaters. I am almost done with the remodel on the inside and I just noticed this problem now, so I dont wana go any further incase I have to rip something out.. anyone have any suggestions, or have had this happen to them?

Have you confirmed the doors are securely closed? I had that happen to me. Looked closed. But then opened at a stop. Sure glad no one was over there when it happened!
