The nozzle is positioned at a recommended strategic height of 1.2m to 1.4m from the ground to avoid 
obstructions by most domestic furniture while still placing mist close to the base of the fire, maximizing 
the effectiveness of the very small water flow.  

Automist Smartscan Compliance and Fire Performance 

Automist was independently tested by Exova Warringtonfire during the summer of 2015 and was able to 
demonstrate full compliance with the fire performance criteria of the BS 8458:2015.  In short, Automist is 
performance compliant with BS 8458:2015 despite not being fully prescriptively compliant, which is the 
essence of innovations: a smarter approach to reach the same end goal: suppression performance. UKAS 
Accredited Certification Body, BSI have also issued a certificate of verification to BS 8458:2015 (VC 656504). 

The full report "BS 8458: 2015: Annex B, Method for Measuring the Capability of a Watermist System to 
Control a Fire - "Room Fire Test for Watermist Systems with Automatic Nozzles" Document Reference 
356258" can be downloaded from the Plumis website. 

For more details on the descriptive and performance requirements of BS 8458:2015 please see table 3 in
