Automist Smartscan Hydra
Watermist fire suppression systems have demonstrated their value in assisting the protection of life
and property for many years. A correctly designed, installed, and properly maintained Automist fire
suppression system can detect, suppress, and control a fire at an early stage of development, and
activate an alarm. Operation of the system rapidly reduces the rate of production of heat and smoke,
allowing more time for the occupants to escape to safety or be rescued.
When triggered by a Plumis multi-sensor wireless alarm or a wired detector, all the linked sprayheads
will begin scanning. They start measuring the temperatures within the room using an infrared sensor.
The scan is looking for an exceptionally high temperature reading, or a differential increase between
scans. Once the temperature exceeds a threshold that head is deemed to have successfully located a
fire. All heads which locate a fire during a scan are then compared, to see which has the best view.
The selected sprayhead will lock onto the selected location, and activate the high-pressure pump,
driving mains water through the unique nozzle unit, quickly directing a dense fog into the location of
the fire. The high momentum vertical spray orientation with a horizontal trajectory is designed so fires
can be saturated with a turbulent flow of mist, suppressing the fire.
Watermist has a different principle of firefighting to traditional sprinklers which suppress fires by wetting
surfaces and directly cooling the flames with large water drops. Watermist uses fine droplets, which
evaporate at the base of the fire, to extract heat and displace the oxygen fuel. This results in fire control,
suppression, or extinguishment. Our sprayheads are wall mounted (around light switch height) to avoid
ineffective evaporation in the hot layer near the ceiling and the upward flow of hot combustion products.
Automist leverages the natural turbulence the fire creates and seeks to ensure watermist is entrained in the
fire plume.
Plumis the manufacturer of Automist is a member of the International Water Mist Association’s (IWMA) and
of its “Archimedes Club” for products which utilise the principle of buoyancy to improve the performance of
water-based fire-fighting systems. Archimedes principle states that the upward buoyant force exerted on a
body immersed in a fluid (i.e. liquid or gas), whether fully or partially submerged, is equal to the weight of
the fluid that the body displaces and acts in the upward direction at the centre of mass of the displaced
fluid.
The provision of Automist does not negate the need for other fire precautions or practical measures, which
can include structural fire resistance, escape routes, smoke or fire detectors and safe housekeeping
practices. Even with the installation of Automist, normal actions on the discovery of a fire need to be taken,
such as immediate evacuation and calling the fire and rescue service.
Automist maintenance is not complex but is essential. It is important that owners and occupiers pay
particular attention to the details within, such as the avoidance of obstructions to the watermist nozzle (see
page 30) and contacting an Authorised Automist Installer to address fault conditions (see page 100).
