FIRE PROTECTION SYSTEMS 3 control valves and manual hose valves in a fire-resistive environment. Manual wet standpipes are commonly found in mid-and-high-rise buildings though rarely installed in newly built structures. They have been replaced by the combined standpipe and fire sprinkler systems (Jones, 2015). These systems are designed to allow for a rapid deployment of hose lines and conduct interior operations away from the engine pumper while keeping stairwells clear for exiting occupants. Components: NFPA 14 addresses the standard at which a standpipe or hose system is installed. It is composed of a series or risers, pressure regulating devices, water flow-control valves, and a fire department connection (FDC). Risers are the piping system that carries water from the supply point to its discharge point. At each discharge outlet there will be a pressure gauge that indicates water pressure in the system with or without the assistance of a pumper’s engine. The pressure regulating device is located commonly on the valve and allows each floor to have a manageable water pressure. Fire detection and alarm systems are the most common fire protection system installed. The system works together with other fire protection systems, provides an early warning to occupants of a building and information on the location of the fire to fire fighters. Fire alarm and detection plays a vital role in risk reduction by monitoring fire pumps and elevators, and integrating with emergency communication and mass notification systems. Many schools have begun to change over to an integrated system to provide information not only on fires but other threats that may arise. Fire alarms have several components that work together to detect fires and notify occupants. Alarm control panels operate from a primary power source to monitor the integrity of smoke, heat, duct, spot, line, and air sampling detectors. Detectors are the automatic initiating devices that detect smoke from a fire and send a signal to the panel to activate any number of notification devices such as bells, horns, strobes or sirens.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
