How Automist Works

In the event of a fire, the system is triggered automatically by a ceiling mounted detector. Unlike conventional sprinklers, Automist® can be stopped manually by pressing a button on its control panel. As Automist® uses much less water than a traditional sprinkler system, water damage in the event of activation is minimised. Where desired, manual activation can also be provided through a manual call point.

Once triggered, a small pump drives mains water through the unique nozzle unit, quickly filling the room volume with a dense fog. Automist Smartscan has the best performance in the range, as it is targeted an infrared sensor, scans the room to locate its hottest point. Water mist removes heat and displaces oxygen from the fire zone, resulting in fire control, suppression or extinguishment. The intention is to lower the temperature, lessen the radiative heat and reduce the oxygen concentration to such an extent that combustion can be longer be maintained, and therefore reducing damage and maintaining survivable conditions.

Adding water to a kitchen chip pan fire can greatly exacerbate the fire, the same is not true for water mist, as the updraught from the flame and the evaporation of the tiny droplets prevents water from reaching and collecting in the pan.
