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 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.
Fire sprinklers can be open orifice or automatic. Automatic sprinklers are activated by heat that breaks the sensing device keeping the sprinkler closed. The water from the pipe comes through the sprinkler and hits the deflector and gives a water spray.
Fire Water Supplies
The water supply to the fire pump in fire sprinkler installations must fulfill the requirements for flow, pressure and duration. Sources can be public water mains, water storage tanks and inexhaustible sources like lakes, rivers and canals
A viable alternative to conventional radiator style heating systems is under floor heating. A typical solution consists of small bore pipes, laid in the concrete slab under the floor’s surface. The solution is typically fed by a condensing boiler or district heating.
