smoke outlet definition
smoke outlet means a smoke removal system in the event of fire (heat smoke removal) as a result of which a stabile, low-smoke layer develops close to the ground which enables the safe use of emergency exits. The system creates a stable, low-smoke layer of air in vicinity to the ground, which facilitates the use of escape and rescue routes. In accordance with DIN EN 12101 part 2, a SHEV must always be used in Germany if a natural „smoke outlet“ is required by construction regulations.
