Automist Smartscan Hydra®

Automist Smartscan Hydra

Watermist fire suppression systems have demonstrated their value in assisting the protection of life and property for many years. A correctly designed, installed, and properly maintained Automist fire suppression system can detect, suppress, and control a fire at an early stage of development, and activate an alarm. The automatic operation of the system rapidly reduces the rate of production of heat and smoke, allowing more time for the occupants to escape to safety or be rescued.

​

The controller continually monitors the thermopile sensors by reading the temperature while parked, ensuring that all heads are ready to operate. When triggered by a Plumis multi-sensor wireless alarm or a wired detector, all the linked spray heads will begin scanning. They start measuring the temperatures within the room using an infrared 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 fires can be saturated with a turbulent flow of mist, suppressing the fire.

​

What to do if the system activates?

​

Once the system is activated, it will remain beeping whilst the pump is running.

To stop it, you can either:

 

1. Wait until the pump has run continuously for 30 minutes. It will then exit to Idle mode (uncommissioned)

​​

2. Press the stop button and the pump will stop discharging but the system will remain beeping for 12 minutes. During the first 2 minutes, the pump will not discharge again, but between the end of the second minite and the end of the 12th minutes (therefore during the last 10 minutes), if a detector is activated again the pump will restart and will discharge mist at the same direction it first discharged. This mode was created to address the fire returning after an occupant believes it has been extinguished, at which point they stop the pump discharge and exit the property. When in this mode, do not switch off the power or it will reset the 12-minute timer. If the alarm condition has ended, Automist Smartscan Hydra will return to an uncommissioned state and requires full recommissioning.

 

Please be patient and wait for the 12 minutes to end before trying to recommission the system.

​

IMPORTANT! Reporting fires which have been controlled or extinguished fires, false positives or false negatives is useful for Plumis for continuous improvement. Please contact Plumis (technical@plumis.co.uk). Further information can be gathered from the system as Automist has a "blackbox” (like aircrafts) that logs all the product's activity and input from sensors to validate that it was a growing fire that was tackled.
