Help me identify a TV program

[RaNkeri]

Ok, so few days ago me and my friend were remembering the times when we were lil' kids. We mostly talked about toys, games and tv programs, and there was this one tv program, that both of us remembered, but couldn't recall it's name.

It ran here in the early 90s and told about the rescue system(or whatever) of USA. This program had a host who was in large hall with different kind of vehicles(like police cars, ambulances etc.) and he always worked as a narrator when they were showing video tapes where people were in a need of help.

If I remember it right, its name was 911-something.
