Where should Automist's sprayheads be positioned?

Automist is not solely reliant on ‘line of sight’, it fills the volume with watermist and uses Archimedes Principle whereby watermist is entrained into the base of the fire leveraging the natural turbulence created as it tries to grow. We utilise preferred positions (typically alongside light switches), multiple overlapping spray patterns in larger rooms and our layout rules (which assume the worst-case scenario with an obstruction alongside our sprayheads) when specifying our system. This short video summarises our strategy:

We have also conducted numerous worst-case scenario fire tests:

  • Tackling a fire with a 1.2m high obstruction between the fire load and the sprayhead
  • Forced ventilation (at least 1m/s) with a fan blowing away the mist
  • Performance in a room almost double the size of the average room size in the UK
  • Performance when a fire is directly below the sprayhead

All these factors show that it can achieve survivable conditions even in challenging circumstances beyond typical use.
