The Plumis Automist® System

Automist® is an award winning retrofit fire sprinkler that uses mist technology for a revolutionary way to implement domestic fire protection across modern open plan buildings.

Today’s building regulations can be extremely restricting, particularly in regards to projects higher than two stories where staircases and hallways are being combined into living spaces.

The provision of inadequate fire protection can mean the difference between life and death. Because it does not need a tank or a commercial incoming water main, Automist® is trusted in thousands of homes to meet building regulations where a traditional sprinkler would not be practical due to water supply requirements.

Automist® can be used in the same residential applications as traditional sprinklers. It is described in an LABC Registered Detail (EW534) and passed all the fire performance tests that are applied to both conventional sprinklers & watermist sprinklers.

  1. Automatic Fire Detection

    In the case of a fire, Automist® is triggered automatically via a detector mounted on the ceiling.

  2. Smart Mist Technology

    Once triggered, a small pump works to drive mains water through the unique nozzle unit, filling the room with a dense fog.

  3. Active Temperature Control

    The water mist removes radiative heat from the room and displaces oxygen from the point of fire, resulting in efficient fire control, suppression, or extinguishment. Combustion is no longer maintainable – reducing fire damage & maintaining a survivable condition.

  1. Minimised Water Damage

    Automist® uses up to 90% less water than a traditional sprinkler, meaning water damage in the event of activation is minimised. Unlike conventional sprinklers, Automist® can also be stopped manually by pressing a button on its control panel, allowing more control and reducing disruption.

  2. Intelligent Fire Suppression

    In the case of a kitchen chip pan fire, it’s widely known that adding water can greatly exacerbate the fire and make the situation much worse. Automist® uses water mist to prevent water from collecting in the pan.

  3. Fast and Effective

    The Automist® system is fast and effective, and in cases where it’s unable to completely extinguish a fire, it can significantly delay the growth - allowing adequate time for escape and keeping temperatures down until fire rescue services can attend.

What layouts can I unlock?

As well as helping to gain approval for open plan arrangements with rooms above the first floor, Automist® can be used to unlock a variety of open plan & above first floor layouts.

New or converted four-storey houses must have two separate escape routes between the upper floors. In a case study with ground, first, second, and third floors, this would mean two separate staircases between the third and second floors. Fitting Automist® would help do away with the requirement for this extra staircase.

In London, prices of around £6000/m2 would mean that an internal stair of standard size (3.5-4.6m2), effectively removes a floor area worth up to £27,000. When you consider these figures, fire suppression pays for itself.

New homes and extensions more than 45m away from the road. If a fire engine can’t get to it, part B5 of the building regulations will see an issue with your project. Fitting Automist® enables the metre distance to be greater (subject to agreement by Building Control & Fire and Rescue).

Easy installation alternative

An easy to install, less disruptive alternative to water sprinkler systems. Automist® was designed with retrofit in mind, and installation can take just 2 hours to complete. The use of a flexible, high pressure hose means that the system does not need to go through the ceiling. A commercial grade water main or tank is also not required for installation.

Installation Timeline

You have been advised by Building Control that you require a sprinkler system.

We’ll help you refine a design that will meet their specifications, through the use of Automist®.

Once we have approval from Building Control, the site is prepared during the early stages of the build/refurbishment. Cables are run in the agreed locations & water and electrical services are provided.

Automist® equipment & hoses are installed in the agreed cupboard and wall locations. The Automist® equipment is connected to the electrical & water services, and spray heads are connected up to pumps.

We operate the Automist® system to test for leaks, verify that the alarm activates, and ensure that the correct operating pressure is reached.

Automist® is installed and ready to protect the property & its inhabitants in the event of a fire.

How Much Does Automist® Cost?

Automist® offers effective active fire suppression, without the costly shortcomings of traditional sprinkler systems in a domestic setting, such as excess water damage, fire damage due to slow response, and difficulty to install and maintain.

Design aspects such as the position of the mounted nozzles & early activation mean that the Automist® system only needs 5.6 litres of water per minute to suppress the same fires that require ten times as much water from a traditional sprinkler system. This means that Automist® does not require a large tank or water main upgrade, which can be quite a significant cost barrier for many properties.
