1. What are some of the common myths and facts regarding automatic fire sprinkler system operation and performance? A myth about fire sprinkler systems is that when one sprinkler head releases water, it triggers all the sprinklers in that system to release water. The truth is each sprinkler head is individually set off until the capsule inside is heated to its melting point and the water is then released. 2. What was the primary purpose and the secondary benefit derived during the first 80 or so years of automatic fire sprinkler system design and installation? The primary purpose during the first 80 or so years of the automatic fire sprinkler system was to control a fire. 3. How do thresholds affect the requirements to install automatic fire sprinkler systems? Thresholds specific to the use or occupancy condition establish whether the code requires or omits the sprinkler system. 4. Name and explain the application for the three most widely used NFPA standards that deal with automatic fire sprinkler system design and installation. NFPA 13 - commercial and industrial properties; this design has the ability to control a fire and is more than adequate enough to extinguish a fire before manual firefighting is necessary. NFPA 13D - one and two story houses; provides guidance to design, layout, and install an affordable home fire sprinkler system that will allow occupants enough time to escape or receive rescue assistance NFPA 13R - residential occupancies up to 4 stories high; combines 13/13Dprovides life safety and property protection to multi-occupant and multi-dwelling residential facilities 5. When designing an automatic fire sprinkler system, what is the primary design goal? The primary goal when designing a fire sprinkler system is to control a fire within minutes of it starting. 6. When designing a residential fire sprinkler system, what are the design goals? A residential fire sprinkler design goal is to operate substantially faster than standard response sprinkler heads for the purpose of sustaining a tenable environment and preventing flashover in the room where the fire starts. It is also to improve the occupant’s chance for rescue or escape. 7.
