Hi everybody. I'm italian and reading "fire" books I often find mentioned the "3-11"; what does exactly means? And which are the other codes used in the US? Thanks, dedox.
I think for Chicago Fire Dept. alarm system for 3-11 Alarm. Like from Still alarm, 2-11, 3-11 and so on. Any guys from Chicago what 3-11 Alarm means in terms of resources needed? thanks
