Project ONE

A Plumis Automist Smartscan system was installed recently in a loft conversion in St Albans, Hertfordshire in order to facilitate the retention of the open plan living space. For this kind of contemporary, open space design Building Regulations demand that a protected enclosed stairwell is provided or they require the use of alternative compensatory measures such as sprinklers.

About Project

The property owner, Mark Watters was reluctant to install sprinklers because of the potential water damage to his home should the sprinklers be activated. He was recommended to consider the Plumis device and did some research on the internet. He was fully satisfied that it would fulfil his requirements as a more usable alternative to sprinklers, so he contacted his local approved Automist installer, Herts Misting Solutions. LABC registered Automist Smartscan is a modern alternative to a fire sprinkler system. Instead of the typical ceiling-mounted sprinkler head, this device consists of a wall mounted stainless steel panel that seamlessly integrates into the interior of almost any living space. As soon as the system is activated, the head of the unit rotates automatically to directly target fires with a powerful jet of water mist. This has been proven to achieve the same performance as the more familiar sprinkler systems. However, because this approach uses 90% less water there is significantly less water damage to the living space in the event of a discharge.


Due to the size and unconventional layout of the ground floor, it was necessary to install two spray heads  and two pumps.  In this case, the pumps were located in a bespoke unit located in the utility room. and the spray-head mounted in the kitchen and living space. Wireless AICO heat alarms complete with Wireless relay units were installed and connected to the pumps. The power supply was run in heat resistant cable (FP200) from an existing consumer unit, on a separate RCBO. All plumbing work, electrical work and making good was completed by Herts Misting Solutions.


Mr Watters was pleased that Automist helped avoid the need to create an enclosed lobby to the exit from the bottom of the stairs, which exited at ground floor level into an open plan living space.  He would most definitely use the Automist system again and indeed would recommend it to others.
