We’ve improved the overall design, in order to have multi-room functionality so now one pump can supply up to six heads.
When triggered by a Plumis multi-sensor (optical smoke plus heat) wireless detector or a wired detector, all the linked spray heads, in the room where the alarm sounds, 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. All heads compare data to see which has the best view of the fire. The selected 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 better than a traditional system which has no control over the number of heads that activate (which can result in excessive water supply requirements). Hydra is designed to supply water to only one head which is why it consumes so little water.
