While true, the vast majority of the time if something beyond an alarm is going on it will get paged as such. I have been on/heard of more calls coming in as structure fires/gas leaks that were not than I have alarms being a fire/leak.
Well yes a majority of the time it's nothing. Departments don't go in thinking an alarm is nothing though (at least they shouldn't) most departments respond as if it's an actual fire or leak. Just speaking from a realistic perspective, I understand what your'e saying though...
