Lumi-Plugin, which offers a downlight with multiple plugins providing a variety of safety features, is partnering with iMist, one of the UK’s foremost suppliers of high-pressure water mist fire suppression systems.
The two companies recently put the concept through its paces with a live fire test at the Fire Protection Association’s Annex C laboratory in Gloucestershire. A Lumi-Plugin LED downlight was installed with an iMist nozzle and mounted on the company’s standard stainless-steel flexible hose, run above a plasterboard ceiling. A fire fuel load was then ignited beneath the nozzle with the heat causing the bulb in the nozzle to burst and activating the iMist high-pressure water mist system.
During the next 30 minutes, firewater mist particles were discharged at high pressure and the temperatures at various heights and positions in the test cell were measured by thermocouples. The test demonstrated that at no point were any of the Annex C temperature limits breached and the fire was successfully suppressed. It also showed that that the Lumi-Plugin light adapter was operating correctly before, during and after the live fire test was conducted and sustained no visible damage during the test.
Alex Pollard, operations director of iMist, comments: ‘At a time when fire safety is a major concern both within the housing sector and the public at large, it’s vital that forward-thinking companies like Lumi-Plugin and iMist come together and combine their technology to offer new fire safety solutions.
‘This is a groundbreaking test which we believe is the first time that a high-pressure water mist system has been successfully incorporated into a downlight. This Lumi-Plugin option combines the water and cost-saving benefits of our fire suppression system in an ingenious application which is easy and fast to install and doesn’t spoil the look of a room.’
Bob Ward, managing director of Lumi-Plugin, added: ‘Over the last seven years, our revolutionary products have become known for their fire safety and energy-saving innovation while uncluttering ceilings and creating streamlined interiors. As part of our ongoing R&D programme, we are continuing to develop additional safety features and we are pleased to join forces with iMist to offer customers this latest plugin as part of our mission to enable them to create safer and smarter properties.’
