Room Compatibility
A single Automist pump unit was tested by Exova Warrington in an area of up to 32 square metres (2.5m
ceiling height) with fire hazards up to 5m away. The spray head should therefore be within 5m of & in the
approximate line of sight of any fire hazards.
Small potentially blocked or shadowed floor areas shall be permitted on a horizontal plane in
compartments of 64 m
2
(two pump units) or less as long as the total area of all individual contiguous
shadowed floor areas, regardless of geometric configuration, does not exceed 2 m
2
.
The maximum ceiling height must not exceed 3.5m following the guidance on BS 8458:2015. Higher ceiling
applications require the involvement of a fire engineer.
More information on Automist’s
appropriateness for a given space is available. Please refer to our technical
area online or contact our technical team.
IMPORTANT:
Do not install Automist outside this specification without first discussing the design with
Plumis. Installing Automist outside these guidelines without properly documenting and agreeing such
variations could make you responsible for deaths or injuries.
