Water-Based Fire Suppression Systems, Fire Inspection and Code Enforcement Chapter 12 8th Edition Rated A+ What are used in their basic forms as the first line of defense against fires Automatic sprinkler systems NFPA 13 Standard for the Installation of Sprinkler Systems What's the percentage of all fires that were controlled or extinguished by sprinkler system 94% What provides the first line of defense of incipient fires Portable fire extinguishers A fire suppression system should be able to discharge the agent directly on the fire or in a manner that floods the fire area before can expand beyond the _____________ phase Incipient Continually charged with water under pressure that discharges immediately when heat from a fire activates one or more sprinklers Wet-pipe sprinkler system Continually charged with compressed air. When a sprinkler activates, the air is released, allowing the dry-pipe water flow control valve to operate and charge the system with water Dry-pipe sprinkler system Consists of open sprinklers attached unpressurized dry pipes. All sprinklers discharge water simultaneously Deluge sprinkler system Continually charged with air that may or may not be under pressure. The system only operates when a sprinkler opens due to a thermally sensitive device activating and one or more detection devices in the same area triggering the water flow control valve open Pre-action sprinkler system Wet pipe system that is continually charged with an antifreeze solution that must be tested annually Antifreeze sprinkler system Wet pipe system that uses the sprinkler system to circulate water for non-fire protection building services such as heating or cooling Circulating closed loop sprinkler system A system that is continually charged with air under pressure combined with a detection system that controls the operation of the water flow control valve. This system is used in special circumstances where an additional level of protection against false activation is required. It is also known as a double pre-action system or double interlock system Combined dry pipe and pre-action sprinkler system System designed to be operated repeatedly in response to the detection device Multi cycle sprinkler system What system allows water flow from multiple directions; however, branch lines are not interconnected like they are in a grid system Looped sprinkler system The water supply must be able to deliver the required volume of water to the highest for most remote sprinkler in the structure while maintaining a minimum required residual pressure in the system. T/F True What determines the minimum water flow required for the sprinkler system Hazard being protected, Occupancy classification, And fuel load conditions Water control valves must be _______________ type valves when used in an automatic sprinkler system Indicating Gate valve that has a yoke on the outside with a threaded stem or screw Outside stem and yoke Underground gate valve that has a hollow metal post attached to the valve housing. The valve stem inside the post has a target on which the words opener shut appear Post-indicator valve
