I've installed these gas detection systems in parkades. In all the ones I've installed we configure them for two stages at separate trip levels. Stage 1 kicks on the exhaust fans but no audible alarm, Stage 2 is the audible alarm.
Unless something has mechanically failed, like the exhaust fan failed to start, the system should never normally hit stage 2. (Or the installer never properly setup the trip thresholds)

How loud is the stage 2 alarm? This is like a loud beeping and then the fans fire up. Not like a fire alarm but definitely enough to get your attention.
