Redundant Fire Protection System
Redundant Fire Protection System : A fire protection system that is designated and installed to function in the event of the failure of a primary fire protection system. Where redundant fire protection systems are specified, any two of the following are considered satisfactory: (1) Automatic suppression systems, such as fire sprinklers, foam, gaseous, explosion suppression, or other specialized extinguishing systems plus appropriate alarms. An adequate supply, storage, and distribution system is an essential element. (2) Automatic fire detection, occupant warning, manual fire alarm, and fire alarm reporting systems (considered together) combined with a sufficiently-staffed, property-equipped and adequately-trained fire department or brigade that are able and committed to respond in a timely and effective manner. (3) Fire barrier systems or combinations of physical separation and barriers for outdoor locations. (4) Other systems, such as alternate process control systems, as approved by the Authority Having Jurisdiction. Redundant fire protection systems may include dual water supplies to sprinkler systems, dual piping risers, or valving systems such that adequate redundancy in water supply by the sprinkler heads is provided to cover maintenance or emergency outages of either of the water supply systems or may include multiple types of automatic fire suppression systems (e.g., water sprinklers and a gaseous fire suppression system). Portable fire extinguishers, interior fire hose systems, or interior fire detection and alarm systems do not meet the definition of a redundant fire protection system
