Plumis Accredited

The Smarter, Modern equivalent to a fire sprinkler system.

Plumis Accredited Installers

We at Unite Security and Electrical Services have recently become Accredited Installers of Automist and other Plumis products.

Automist must be specified and commissioned by an Accredited Installer. We regularly install Automist in a wide variety of projects nationally, and we are fully trained to ensure that high standards are maintained,  we have received our Plumis Certificate of Accreditation following successfully completion our training.

Automist Smartscan

Over the years we’ve changed how we design our homes. It’s about time we changed how we protect them, too. Introducing Automist Smartscan, an evolution of the James Dyson award-winning Automist. Smartscan has a rotating head that directly targets fires with a powerful jet of water mist.

Contact us for more information and we can provide you further details on this excellent new product range.

Automist® Smartscan has a rotating head that directly targets fires with a powerful jet of water mist. It has been proven to achieve the same fire performance as residential sprinkler systems, and typically uses 90% less water minimising consequential water damage to the living space.

Fixed System

A standard Automist® installation requires a dedicated mains circuit in FP200 cable and a water supply with 1-10 bar pressure and a flow of at least 6 litres per minute. It can be installed seamlessly and unobtrusively to meet building regulations in a number of configurations:

Personal Protection System

Automist® PPS is a portable version of the Automist system with an integrated water tank and battery back-up system. Automist® PPS provides water mist personal protection, in an easily installable and removable package which does not require a dedicated power or water supply.

SmartScan

We believe that we’re taking the next step in fire safety. We allow home design to be as beautiful as possible, while delivering a solution which meets industry fire performance standards.

What is Automist?

Automist® is a simple, retrofittable, sprinkler-alternative for full room active fire protection. Perhaps you are a homeowner looking for peace of mind from kitchen fires, an architect trying to enable open plan living (LABC Registered detail for loft conversions – EW171), or even a landlord looking to safeguard your tenants. Automist is changing the way people think about domestic fire protection.

Plumis FAQs

Automist is an innovative product designed to help compliance with building fire regulations, particularly in open plan layouts. Such products are permitted under Building Regulations as long as they have been tested and shown to be fit for purpose. A similar framework of requirements exists for the Fire Safety Order and the Housing Act. Automist’s testing was conducted by BRE and is framed around demonstrating a survivable set of conditions in the room of origin of the fire by minimising toxic gas / low oxygen / heat exposure..

Automist is triggered by an industry standard 57°C heat alarm. Heat alarms can either be mains or battery powered and must have a relay output either via a wireless or wired connection. The relay should include Normally Open, Normally Closed and Common terminals (a relay without Normally Closed can be accommodated with a modification by Plumis). Alarm panels may be used provided that they offer a suitable relay output.

A correctly installed heat alarm will reliably trigger Automist and should supplement household existing smoke alarms which can provide an additional warning of fire. Heat alarms give an audible warning when the temperature at the alarm reaches 57°C and, unlike conventional smoke alarms, will not be triggered by burning the toast, steam from cooking, or a car’s exhaust fumes.

When water is driven through a specialised nozzle at very high pressures (in Automist’s case around 80 bar), the water is atomised to produce a fine mist or fog. Water mist removes heat from the fire and displaces oxygen from the fire zone, resulting in fire control, suppression or extinguishment. The intention is to reduce the oxygen concentration around the flame, lower the temperature and lessen the radiative heat to such an extent that combustion can be longer be maintained, thus reducing damage and maintaining survivable conditions.

In the event of a fire, Automist is programmed to run continuously for 30 minutes or while the alarm input remains active, whichever is the longer. This prevents interruption of mist operation if the room temperature drops below 57°C while a fire is still present. For installations where a fire panel will be controlling Automist, it may be set to operate only while its alarm input remains active. Automist uses approximately 10% of the water of a traditional sprinkler system, running at approximately 5.5 lpm, and therefore minimises consequential water damage and runoff. The system can be stopped at any time by pressing a button on the control unit.

Automist’s suitability as a compensatory measure is ultimately determined by the authority that has jurisdiction over your project, for example your building control officer or approved inspector. In the case of LACoRS guide compliance this will normally be your local authority housing officer or in some cases, Fire and Rescue.

For building control purposes, Automist is the subject of an LABC Registered Detail (EW171) for use in open plan layouts in loft converted houses. The Registered Details scheme should allow building control officers to approve compliant properties without a long and detailed investigation.

You can consult Plumis’s Before You Buy guide to determine general suitability for your project. The guide explains how some projects are more easily approved than others and outlines some of the key options. Automist may not be the best option for every project, and some layouts are not approvable even with a full sprinkler system throughout the property. If it’s not clear that your project can be easily approved, it will sometimes be possible to move forward with a custom fire engineered solution designed specifically for your project; it may also benefit you to make sure (before you start building) that you have selected a building control service that has the relevant specialist expertise in fire.

* Prices are guidelines per home (retrofit) and depend on the specific products used, economies of scale, and project complexity.

Automist can be interconnected with many existing alarm systems, including the use of manual call points, however some caution is required. Where an existing system includes smoke alarms, it is essential that Automist not be triggered when these alarms are activated. Ei/Aico alarms provide sufficient flexibility to allow Automist to be activated only by the relay base of an interconnected heat alarm, and not when the other alarms sound. Other manufacturers may not offer this level of flexibility. Where a fire alarm panel is used, Automist can be driven from a volt-free relay output provided that the panel provides suitable zoning / cause-and-effect options.
