It primarily covers the systems use for life safety but might also provide property protection.
    • Understanding Standard and Innovation.pdf
      Innovative products often tend to be patented and do things differently from convention as a result they often fall outside of the scope of existing Standards. This, however, does not prevent them from demonstrating they are fit for purpose.

    • Replicating the activation time of electronically controlled watermist system nozzles in B-RISK.pdf
      A combination of an effective RTI of 20 m½s½ and an effective C factor of 0.25 m½s has been shown to reasonably predict activation times for an electronic nozzle system. For the specific experiments presented in this paper the measured activation times of a concealed sprinkler head are 2.0 to 13.7, 26 times slower than those using an electronic nozzle system.
    • Probabilistic Modelling of Automist in Open Plan Dwellinghouses.pdf
      In carrying out a review of both the performance objectives of suppression systems in dwellinghouses and the Plumis Automist documentation and research to date, sufficient evidence has been found to indicate that the system can typically perform equivalent to or better than the minimum expectations of a domestic sprinkler system conforming to BS 9251:2021. By extension, it therefore appears reasonable to assume that the Plumis Automist system can adequately support any applications which are otherwise in line with guidance expectations.
      Consideration has also been given to more ‘open plan’ designs which deviate from guidance, through a probabilistic computational fire modelling assessment of a series of representative dwellinghouse arrangements. Overall, the inclusion of a Plumis Automist suppression system in a three-storey dwellinghouse arrangement with an open plan stair is shown to produce a design scenario which is no more likely to result in injury or fatality during a fire than an accepted design that follows recognise fire safety guidance, such as ADB [6] or BS 9991:2015 [8]. As such, it appears a reasonable approach for the Plumis Automist system to be adopted as part of a performance-based, fire-engineered solution where a three-storey dwellinghouse arrangement deviates from the guidance recommendations.
    • Estimating the Suppression Performance of an Electronically Controlled Residential Water Mist System from BS 8458:2015 Fire Test Data.pdf
      Three traditional suppression assumptions, historically derived from experimental data for sprinklers, have been adopted in the zone modelling to examine whether their application following system activation can be extended to the tested water mist system. The work indicates that applying these suppression assumptions remains reasonable in the context of the performance of the tested water mist system, noting the constraints of the test methods in representing a limited number of fire scenarios
