Smoke Control – Dual Purpose

These systems are used in conjunction with a series of fire / smoke control dampers

Under everyday operating conditions, the smoke ventilation system works as normal by supplying or extracting air from designated areas.

In a fire condition, however, the dampers on the standard system close and automatic dampers on the emergency system open to allow the system to function as either a smoke extract or pressurisation system. The ductwork must be fire resisting to satisfy the compartmentalisation plan of the building.
