Smoke feedback

Smoke feedback occurs when smoke enters a pressurization fan intake
and flows into protected spaces. Design techniques reduce the probability
of smoke feedback:
Supply air intakes located below openings from which smoke might
•
flow, such as building exhausts, smoke shaft outlets and elevator
vents.
Automatic shutdown capability to stop the system in the event of
•
smoke feedback.
