1Under NAC 624.572, which work is included in C-41a Automatic Fire Sprinklers?
A.Fabrication, installation, alteration, repair, and service of water-based fire protection, including tanks, fire pumps and drivers, sprinklers, valves, piping, control wiring, required excavation, and piping to an adjacent off-premises water supply
B.Only hanging listed sprinklers on an existing wet riser installed by others
C.Foam, carbon dioxide, and dry-chemical systems, but no water-based piping
D.Electrical heat and smoke sensors with no water-based work
Explanation: NAC 624.572(2)(a) defines C-41a as water-based fire protection: tanks, fire pumps and drivers, sprinkler heads and nozzles, associated valves and piping, control wiring, excavation/backfill/grading, and piping to a water supply that is not on the premises but is adjacent to the property. Foam/gas/dry chemical is C-41b. Heat and smoke sensors are C-41c.
2In NFPA 13 (2007), which system keeps water out of the branch piping until a detection system operates, then fills the piping and discharges only from sprinklers that have opened?
A.A wet-pipe system
B.A deluge system with open nozzles
C.A single-interlock preaction system
D.A pipe-schedule standpipe
Explanation: A single-interlock preaction system admits water when the detection system operates. Closed sprinklers then discharge individually when they fuse. NFPA 13 (2007) Chapter 7 uses preaction where accidental water discharge must be limited, such as computer rooms or museums, while still providing automatic sprinkler protection.
3NFPA 13 (2007) requires sprinkler-system control valves to be of which general type so their position can be determined without operating them?
A.Non-indicating underground corporation stops only
B.Any gate valve, including a non-rising-stem buried valve with no post
C.A pressure-reducing hose valve
D.Indicating valves, such as an OS&Y or a listed butterfly valve with a position indicator
Explanation: NFPA 13 (2007) 8.16.1 requires listed indicating control valves so open/closed status is obvious. An outside-screw-and-yoke (OS&Y) valve shows a rising stem when open. A listed indicating butterfly (or a post-indicator valve on underground supply) also satisfies the rule. The valve is electrically supervised where the building fire-alarm system is required to watch it.
4Per NFPA 13 (2007) Table 6.2.5.1, a sprinkler whose frame is painted white is in which temperature classification?
A.Intermediate (175°F to 225°F)
B.Ordinary (135°F to 170°F)
C.High (250°F to 300°F)
D.Extra high (325°F to 375°F)
Explanation: NFPA 13 (2007) Table 6.2.5.1 uses frame/paint color for temperature class. A white frame is intermediate, 175°F to 225°F, for a maximum ceiling temperature of 150°F. Ordinary frames are uncolored or black. Blue is high, red extra high, green very extra high, and orange ultra high. Glass-bulb liquid colors are a different code (orange/red ordinary, yellow/green intermediate, blue high, purple extra high).
5Unless a listing requires a higher value, what is the minimum residual pressure NFPA 13 (2007) allows at a standard spray sprinkler?
A.7 psi
B.15 psi
C.20 psi
D.50 psi
Explanation: NFPA 13 (2007) 8.3.3.1 / 22.4.4.9 set a 7 psi floor at each operating standard spray sprinkler unless the listing is higher. Residential and some extended-coverage listings need more. Hydraulic calculations must keep every remote-area head at or above that floor while also delivering the required density.
6Unless a storage-specific chapter applies, what minimum clearance does NFPA 13 (2007) require from the sprinkler deflector down to the top of storage?
A.6 inches
B.12 inches
C.18 inches
D.36 inches
Explanation: NFPA 13 (2007) 8.6.6.1 requires at least 18 inches from the deflector to the top of storage for standard spray sprinklers. That clearance lets the spray pattern develop. Storage chapters can require more, and some special sprinklers have listed exceptions, but 18 inches is the default occupancy-sprinkler rule.
7For standard spray upright or pendent sprinklers in Light Hazard under unobstructed construction, what maximum protection area and maximum spacing does NFPA 13 (2007) Table 8.6.2.2.1 allow?
A.100 ft² and 12 ft
B.130 ft² and 15 ft
C.225 ft² and 15 ft
D.400 ft² and 20 ft
Explanation: Table 8.6.2.2.1 of NFPA 13 (2007) allows 225 ft² per standard spray sprinkler in Light Hazard with unobstructed noncombustible or limited-combustible construction, and a 15 ft maximum spacing. Half of 15 ft is the usual 7.5 ft maximum from a wall. Combustible obstructed construction tightens the area.
8A Light Hazard office is sprinklered with standard spray pendent heads on 15 ft by 14 ft spacing. What protection area does each sprinkler cover, and what minimum flow is required at 0.10 gpm/ft²?
A.210 ft² and 21.0 gpm
B.225 ft² and 22.5 gpm
C.180 ft² and 18.0 gpm
D.150 ft² and 15.0 gpm
Explanation: Coverage is S × L = 15 ft × 14 ft = 210 ft², which is under the 225 ft² Light Hazard maximum. Minimum flow is density times coverage: 0.10 gpm/ft² × 210 ft² = 21.0 gpm. The hydraulic calculation must deliver at least that flow at each remote-area sprinkler, and pressure must also meet the 7 psi floor or the listing.
9Using the NFPA 13 (2007) Figure 11.2.3.1.1 starting point, what density and remote area apply to Light Hazard?
A.0.10 gpm/ft² over 1,500 ft²
B.0.15 gpm/ft² over 1,500 ft²
C.0.20 gpm/ft² over 1,500 ft²
D.0.30 gpm/ft² over 2,500 ft²
Explanation: Figure 11.2.3.1.1 of NFPA 13 (2007) starts Light Hazard at 0.10 gpm/ft² over 1,500 ft². The designer may move up the density/area curve to a smaller area only if the matching higher density is delivered. Hose stream (100 gpm) and duration (30 minutes) are taken from Table 11.2.3.1.2.
10An Ordinary Hazard Group 1 wet system is calculated at 0.15 gpm/ft² over 1,500 ft². After the NFPA 13 (2007) Ordinary Hazard hose-stream allowance is added, what total water-supply flow is required?
A.225 gpm
B.325 gpm
C.475 gpm
D.750 gpm
Explanation: Sprinkler demand is 0.15 × 1,500 = 225 gpm. Table 11.2.3.1.2 adds 250 gpm of combined inside-and-outside hose for Ordinary Hazard. Total supply at the connection is 225 + 250 = 475 gpm, for a 60- to 90-minute duration. Hose is not added at each remote sprinkler.
