Traditionally, FK 5112 is used for total flooding solutions. It is designed to fully discharged into an enclosed room when there is a fire. For small enclosed spaces, it is also possible to replicate a similar effect. The nozzle is inserted into the the enclosure and fully discharged. The advantage is that it is possible to have a mobile fire suppression system which is cheaper to maintain and has less expensive initial costs. The downside is that it loses the automatic fire detection that the fire suppression system would usually have. This would require a human operator to manually watch for fires and operate.
