Standard EN 12845 standard includes the general rules and recommendations regarding the design, installation and maintenance of fixed sprinkler systems that are used in the buildings and the industry to prevent fire along with specific rules for life protection precautions and systems in all of the European community countries. Fire-fighting Booster Set Specifications General Properties of the Fire-fighting Booster Sets Fire-fighting booster sets are designed in line with EN 12845 standard. Its modular structure accelerates and facilitates the selection of fire-fighting booster set group. Each module is mounted on a electrostatic epoxy painted steel frame in line with EN 12845 standard. Booster set assemblies are in an assembled module form with electrical panel cabling. Each module is manufactured in line with EN 12845 standard. The pumps are activated automatically with a command from pressure switch and then. They are deactivated manually. Diesel pump module is activated in line with EN 12845 standard. Diesel pump emergency manual operation is also in line with the standard. Main pump modules have inlets that are suitable to be connected to 1" forward-feed tanks (operation tank) in case they will be operated by drawing water from underground tank (negative suction). To prevent mechanical seals to be damaged during closed valve test operations, pump modules have the ability of back circulation to the water tank or the operation tank. The sections allocated for pump modules should be sprinkler protected. EN 12845 Fire-fighting booster sets are factory-calibrated and tested. Thus they enable fast and easy assembly. Remotely monitored alarm panel provides acoustic and visual warnings. Eccentric reduction suction kit is standard including negative suction assembly. The collectors are designed to prevent exceeding 1.8 m/second water speed in positive suction.
