How does Automist Smartscan Hydra detect a fire?
When Automist Smartcscan is triggered by a multi-sensor wireless or a wired detector, all the linked spray heads begin scanning. They start measuring the temperatures within the room using an infrared 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.
The Plumis wireless detector DT01 is a custom version of the Apollo multi-criteria smoke + heat alarms 51000-150 / 51000-357 which is designed to EN 14604:2005 and UL217 respectively. The Plumis CT01 includes a proprietary 2.4GHz wireless communication to the spray heads to indicate there is a potential fire. The combination of a smoke alarm with a temperature sensor improves response time for both flaming and smouldering fires as well as reducing false alarms from certain nuisances such as cooking fumes. It is CE Marked to the harmonised European standards that apply to this alarm.
If any wired or wireless detector connected to Automist Smartscan Hydra is removed or faulty, it will cause the system to enter fault mode and sound. This condition can be hushed for 12 hours by pressing the STOP button but can only be permanently removed by addressing the fault.
With Smartscan we use wired or wireless detectors in combination with scanning infrared sensors on the nozzles to electronically trigger our suppression system. In this way, it acts as an initiation device equivalent to the change of state of an element or bursting of a glass bulb under the influence of heat.
