Automist is suitable for retrofit into high rise as a multi-domestic application.
Runnymede Council began a programme to retrofit sprinklers to flats within its only tower block – the 16-storey Surrey Towers in Addlestone. To avoid issues with access and disruption to tenants, installations took place when they are either subject to major internal works, or at the time of re-letting. The authority adopted the policy a couple of years ago in consultation with Surrey Fire and Rescue Service after reviewing its fire risk assessment in light of the coroner’s ruling following the Shirley Towers blaze.
They selected Automist as part of a rolling multi-domestic retrofit programme, elective fire safety upgrades to individual flats. This can be of benefit where there are neighbouring flats with different ownership types, some being leasehold and some freehold.
As per BS8458, clause 4.3 Category of System:
The designer should at an early stage determine which category of system is applicable, as this affects various design considerations, such as the water requirements for the system. The category of system should be determined by the type of building as shown in Table 1, up to a maximum height of 45 m.
If the type of building is not listed in Table 1, or for buildings over 45 m, then the AHJs should be consulted to agree which type of occupancy should apply, whether additional measures are needed (see 4.6) or whether an alternative system (e.g. DD 8489-1 3) or BS EN 12845) is more appropriate.
