4 Component requirements 4.1 Condensed aerosol generator The condensed aerosol generator typically consists of the following main components: a) solid aerosol-forming compound; b) cooling mechanism (if applicable); c) activation device(s); d) end plate discharge outlet(s); e) housing; f) mounting bracket. The generator is a non‑pressurized canister, because aerosol is generated and distributed by the combustion process of the solid aerosol‑forming compound. 4.2 Solid aerosol forming compound Mixture of oxidant, combustible component and technical admixtures producing fire extinguishing aerosol upon activation. 4.3 Cooling mechanism The cooling mechanism provides cooling of the hot aerosol prior to its discharge into the enclosure. 4.4 Activation device 4.4.1 General The activation device is arranged to initiate the aerosol‑forming compound.If the activation device is a complex device incorporating several components, all components shall be specified by the manufacturer. 4.4.2 Electrical activation device The electrical activation device shall be capable of operating via an electrical input and arranged to initiate the aerosol‑forming compound. 4.4.3 Thermal activation device The thermal activation device shall be capable of operating at a rated temperature and arranged to initiate the aerosol‑forming compound. 4.4.4 Other methods of activation device Methods capable to initiate the aerosol‑forming compound, other than 4.4.2 and 4.4.3, shall be specified by the manufacturer.
5 Condensed aerosol generators requirements 5.1 General The test samples shall conform to the technical description (drawings, parts list, description of function, operating instructions) as stated by the manufacturer (see 5.17 and 7.3). The manufacturer shall specify the minimum distance from the generator outlet to the first obstacle. The manufacturer shall specify the minimum and maximum mass of aerosol compound discharged from the generator. 5.2 Extinguishing density The extinguishing density for specific fuels under different classes of fires shall be determined by test using the fire test protocol described in Annex A.BS EN 15276‑1 pdf download.
