This was the best one I could find and I think it would fit perfect
Itchboy asked for tones, not a station siren. Tones are what your dispatcher drops over the radio to set off Minitor pagers and station sirens like you linked above.
Video is from 13-14 years ago. Except for the most resource-strapped departments and communities, most have probably gone to more modern forms of communications that don't cause loud disruptions to their communities.
We still run our siren at our station. Everything in the fire service is about tradition really. Alot of stations in my area still have those. Across the river if they get a structure fire and alert all four companies, four whistles go off. It has nothing to do with communication other than letting the public know there is an emergency that fire department personnel are responding to. Possibly for weather warnings as well such as tornado, severe thunderstorm etc.
Ever heard of texting or phoning the volunteers? Maybe even a pager?
Read above. also, what do you think they did before texting and or pagers? There were no cells phones back in 1990 and before unless you had the big mobile phone in a bag, which not many people did.
