“According to “ components for fire protection
“According to” components for fire protection, are products or fire pump sets which are built according to specifications written in fire protection standards – for example “according to NFPA 20”. These products are not listed and haven’t been evaluated by a listing laboratory.
Acceptance test of sprinkler systems
An acceptance test of sprinkler systems is to ensure the functionality and performance of the fire sprinkler system is in accordance with design requirements.
Fire extinguishing systems
Fire extinguishing systems are a common expression for systems using different medias to suppress- or extinguish fires in buildings. The medias can be water, foam, gas or chemicals.
Fire hazard classification
The hazard class (LH, OH, HH) to which sprinkler system is to be designed, will determine the characteristics of the fire sprinkler installation in regards of specification of water supply, number of fire pumps, number of sprinklers etc.
Fire hose reel system
Fire hose reels are located at strategic places in buildings to provide a reasonably accessible and controlled supply of water for fire extinguishing.
Fire protection component standard
A fire component standard is a document with mandatory provisions to indicate requirements and testing methods for components or materials to be used within the fire protection system installation.
Fire Protection Standard
A fire protection standard is a document with mandatory provisions to indicate requirements for planning, installation and maintenance of fire extinguishing systems (such as sprinkler systems, water mist -, gas – and foam systems). Overall requirements demanded from the components, such as performance, specifications and listings, is to some degree included.
Fire pump characteristics
Fire-pumps are typically made with non corrosive internal parts to avoid clogging due to corrosion. To avoid cavitation and to have a stable system pressure, the fire-pumps are most often designed specifically for fire-pump purposes, with strict demands to the NPSH value and flow [Q] and head [H] curve.
Fire pump controller
Fire Pump controllers for diesel – and electric driven fire-pumps are given a signal from a pressure-switch to start up the fire-pumps. There is always one control-panel per fire-pump for safety reasons.
Fire Pumps
Fire-pumps are typically listed by an approval institute and can be driven either by an electric motor or diesel engine. In a fire installation there can be one or more fire pumps put into operation as a duty assist (50%) – and standby pumps.
