Smoke and heat control systems are used to protect people, buildings and/or building contents from the effects of smoke and heat in the event of fire. The most common systems are smoke and heat exhaust ventilation systems (SHEVS) and pressure differential systems.
Smoke and heat exhaust ventilation systems (SHEVS) create a smoke free layer above the floor by removing smoke and thus improve the conditions for the safe escape and/or rescue of people and animals and the protection of property and permit the fire to be fought while still in its early stages. They also exhaust hot gases released by a fire in the developing stage.
The use of smoke and heat exhaust ventilation systems to create smoke free areas beneath a buoyant smoke layer has become widespread. Their value in assisting in the evacuation of people from construction works, reducing fire damage and financial loss by preventing smoke logging, facilitating fire fighting, reducing roof temperatures and retarding the lateral spread of fire is firmly established. For these benefits to be obtained it is essential that smoke and heat exhaust ventilators operate fully and reliably whenever called upon to do so during their installed life. A heat and smoke exhaust ventilation system is a scheme of safety equipment intended to perform a positive role in a fire emergency.
Components for smoke and heat exhaust systems should be installed as part of a properly designed smoke and heat system.
Smoke and heat exhaust ventilation systems help to:
—? keep the escape and access routes free from smoke;
—? facilitate fire fighting operations by creating a smoke free layer;
—? delay and/or prevent flashover and thus full development of the fire;
—? protect buildings, equipment and furnishings;
—? reduce thermal effects on structural components during a fire;
—? reduce damage caused by thermal decomposition products and hot gases.
Pressure differential systems are used to either positively pressurise spaces separated from the fire or to depressurise the space containing the fire in order to limit or prevent the flow of smoke and heat into adjacent spaces. A typical use would be to pressurise an escape stair well in order to protect vertical means of escape.
Depending on the design of the system, natural or powered smoke and heat ventilation can be used in a smoke and heat control system.
Power supply equipment for a smoke and heat control system may be for pneumatic systems, low voltage or extra low voltage electrical systems, or a combination of any of these.
Smoke and heat control system power supplies may also provide power for day to day ventilation and for other fire safety equipment under fire conditions.
1 Scope
This European Standard specifies requirements and gives test methods for primary and secondary electrical and pneumatic power supply equipment, designed for use in smoke and heat control systems in buildings.
