I have been having problems with my defualt Dash 9’s alerter. In under 5 seconds after i move a control, it will go off, especially when applying dynamic brakes. I also have problems with it going off in the quicker louder tone first, rather than than the slower, slower tone.
Yea, sometimes you go to an external view, watch it for a few seconds, then a loud HISS!!! And you train is stopped. I think the alerter goes off to often even in the real life, I think every 25 seconds can make you more fatigued than you already are, like an alarm clock. Even then, you still have a conductor, how many times have the alerter been used for its purpose? Probably twice in the last 20 years.
