BRE Smoke Shaft System Components
Each BRE Smoke Shaft System is made up of a set of AOV Kits, each containing a ventilator and associated controls.
At the roof level, there is an AOV Kit for the top of the smoke shaft (AOV Kit F) and one for the top of the stairwell (AOV Kit B). At each floor level, there is a damper kit (AOV Kit E) for the inlet into the smoke shaft. Finally, there is an optional touchscreen panel that can be used for central monitoring and diagnostics if required.
The control system is fully compliant with BS EN 12101:10 and ISO 21927:9 and has built-in safety features, including ‘locking out’ functionality and battery backup power supplies to ensure safe operation.
