Plumis Automist® Hydra SmartScan
1st in Fire Suppression
Automist® Hydra SmartScan is a smarter, modern fire sprinkler system. Instead of the typical ceiling-mounted sprinkler head, this device consists only of a stainless steel panel that seamlessly integrates into the interior of any living space.
It is an innovative, fire protection solution designed to allow open plan layouts to comply with regulations. Several alternative guidance documents support the use of Automatic water fire suppression systems (AWFSS) to meet building regulations:
BS 9991:2015 Fire safety in the design, management and use of residential buildings. Code of practice
BS 7974:2019 Application of fire safety engineering principles to the design of buildings. Code of practice

Welcome to the 21st Century Sprinkler.
When triggered by a Plumis multi-sensor wireless detector or a wired detector, all the linked spray heads will begin scanning. They start measuring the temperatures within the room using an infrared (IR thermopile) 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 spray head 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 even shielded fires are saturated with a turbulent flow of mist, suppressing the fire. All the other heads lock closed. In this way, it is like a traditional sprinkler system designed to supply water to only one head so all the water is supplied over the fire. However, one huge advantage it boasts is that this approach uses 90% less water. The result is significantly less water damage to the living space.
From the point of view of the approving authorities
The Automist technology is proven to be fast acting and effective, either extinguishing or delaying the growth of the fire long enough to escape and the fire and rescue services to attend. It keeps temperatures low, too, delaying flash overs.
