@tagir_valeev More galling still, a scheduled test of a fire alarm system typically *still includes evacuation.* Leaving the building *is* the drill. I have never worked in an office where there was any condition under which occupants are told to ignore the alarm.
Ignoring alarms leads to alarm fatigue which then leads to failure. Alarms either exist for a reason or they don't. A device that says otherwise is a broken device. You're right, devices like that will kill.
