Description
Contraincendios NFPA 20 UL-FM
The protection of lives and property is the main objective of fixed firefighting equipment, based on sound engineering principles test data and field experience, playing a major role in ensuring a supply of sufficient flow and pressure. A long experience in the manufacture of firefighting equipment has allowed its standardization applying international regulations.
NFPA-20 The equipment covered by this standard is manufactured in compliance with the NFPA-20 National Fire Protection Association.
UL Oversight of Underwriters Laboratories Inc. an independent global safety sciences company offering expertise in five key strategic businesses: product safety, environment, life and health, verification services and universities.
FM Factory Mutual Global, the world’s largest commercial property insurance company, certifies product standards by issuing a “FM APPROVED” certificate indicating that the equipment will operate to NFPA-20 and FM specifications.
All these systems require a pressurized water network for their operation. The fire-fighting equipment will maintain the pressurised network, for which they have a small auxiliary pump called a jockey, driven by an electric motor that replaces any possible leaks and drips that may occur in the installation. A small hydropneumatic reservoir helps reduce the number of starts and cushions pressure fluctuations.
The most important features are :
– Joint design of all equipment, ready for automatic fire service
– Modular construction configurable according to the required equipment either single main pump or several main pumps with electric or diesel motor drive
– The pumping equipment is a set of one or more pumping groups being the set capable of providing the nominal flow specified for the system (Qn) required by the standard.
– The appropriate FOC equipment is defined in the selection table, depending on the flow required by the firefighting system, number of hydrants, sprinklers, etc. and the required pressure.
– It is necessary to take into account, the geometric height, between the level of the pumping equipment and the most unfavourable point of the circuit, as well as the load losses of the route.

Depending on the project requirements of the installation itself, different configurations can be distinguished:
FOC FLRN – Formed by :
- Electric main pump with standard pump type FLRN according to DIN 24255
- Diesel main pump with FLRN pump according to DIN 24255
- Auxiliary pump (jockey) with VIPV, NX, NXA pumps
- Starter and control electrical panels
- Valve, pressure limiter, air bleeder, set of pressure gauges.
- Bench
- Optional (test manifold and flowmeter)
FOC FLCP – Formed by :
- Electric main pump with split-case pump FLCP
- Diesel main pump with split-case pump FLCP
- Auxiliary pump (jockey) with VIPV, NX, NXA pumps
- Starter and control electrical panels
- Valve, pressure limiter, air bleeder, set of pressure gauges.
- Bench
