Fire detection elementsElements that respond with a change in state when a fire parameter occurs or changes.Width-height ratioRatio of width to height in bottom hung, top hung, side-hung and dormer windows.CE markingBy affixing the CE marking, the manufacturer confirms that the product conforms to the applicable EC directives.For further information, go to: http://www.vdi-nachrichten.com/ce-richtlinien/basics/index.asp.Coefficient of discharge (Cv) (with side wind influence)Ratio of actual flow rate, measured under specified conditions, to the theoretical flow rate through the naturalsmoke and heat exhaust ventilator. The coefficient of discharge takes into account any obstructions in the naturalsmoke and heat exhaust ventilator such as controls, louvres, vanes and the influence of side winds.Coefficient of discharge (Cv0) (without side wind influence)Ratio of actual flow rate, measured under specified conditions, to the theoretical flow rate through the naturalsmoke and heat exhaust ventilator. The coefficient of discharge takes into account any obstructions in the naturalsmoke and heat exhaust ventilator such as controls, louvres, and vanes without the influence of side winds.Fire open positionTarget opening position of smoke and heat exhaust ventilators to be achieved and sustained while venting smokeand heat.Geometric area (Av)Opening area of a natural smoke and heat exhaust ventilator. Controls, louvres and other obstructions are nottaken into account.Geometric free areaSmallest cross sectional area of a ventilator through which flow occurs.Manual activationInitiation of the operation of a smoke and heat exhaust ventilator by a human action (e.g. by pressing a buttonor pulling a handle).46Section E
Aspect ratioRatio of length to width in side-hung windows.Natural ventilationVentilation caused by buoyancy forces due to differences in the density of the gases because of temperaturedifferences.Natural smoke and heat exhaust ventilator (NSHEV)Device to exhaust smoke and hot gases out of a construction works in case of fire.Dual purpose natural smoke and heat exhaust ventilatorNatural smoke and heat exhaust ventilator that can also be used for day to day ventilation.Opening timePeriod (≤ 60 seconds) between the smoke and heat exhaust ventilator receiving the signal andreaching the functional position (opening position) in case of fire.Smoke and heat exhaust ventilator (SHEV)Consists of components selected to exhaust smoke and heat in order to generate a stable layer of warm gasesabove cooler and cleaner air.Thermal activation elementTemperature-sensitive activation deviceManually opened smoke and heat exhaust ventilatorSmoke and heat exhaust ventilator that can only be opened manually.Wind sensitive control systemControl system designed to control two or more banks of natural smoke and heat exhaust ventilators in differentbuilding side walls so that only the NSHEVs not subject to positive wind pressures open in case of fire.Section E47
