Testing Fire Alarm Advanced Smoke Control

Fire Alarm Test 77
Setting off a very large notifier 3030 voice evac system. Alarms are Wheelock E50 speaker strobes. What's cool about this system is they have an open stairway that becomes a closed positive pressure stairway in the event of an alarm. This is achieve via large roll up doors that close off the stairway and large fans that pressurize it. The reason for this is to prevent smoke from entering the stairway in an actual fire.
