Smoke Control Systems – The Objective
The objective of any smoke control system is to keep the smoke and toxic gases out of an escape route long enough to allow the building occupants to escape or seek a safe refuge. A correctly designed and installed smoke ventilation system will help the fire fighters deal with the fire and any residue smoke.
In accordance with Approved Document B smoke control by pressure differential to aid means of escape must comply with BS EN 12101 part 6. The system works on the principle of creating pressure differentials between areas to prevent smoke entering the primary escape routes. These systems are predominately used in multiple occupancy buildings such as apartments, hotels, care and health establishments, although can be applied to other circumstances.
All systems have duty and standby fan sets. The systems also require primary and secondary power supplies for complete assurance. Systems can be used for environmental control if required.
Further, to suit the application, we can supply integrated control dampers, intelligent controls including fire floor response, pressure differentials, mimic and status display panels and fireman’s override switches.
