1. Which standard is most directly associated with the installation of
automatic sprinkler systems in ordinary commercial and residential
buildings?
A. NFPA 13D
B. NFPA 13
C. NFPA 20
D. NFPA 72
B. NFPA 13
NFPA 13 establishes minimum requirements for the design and
installation of automatic sprinkler systems in many commercial,
industrial, and other occupancies. NFPA 13D and 13R address specific
residential applications, while NFPA 20 primarily covers fire pumps and
NFPA 72 covers fire alarm systems.
2. What is the primary purpose of an automatic fire sprinkler system?
,A. Detect smoke throughout a building before any temperature increase
occurs
B. Provide a continuous water supply for firefighting personnel
C. Control or suppress a developing fire using water discharged from
activated sprinklers
D. Prevent all fires from reaching ignition temperature
C. Control or suppress a developing fire using water discharged from
activated sprinklers
Automatic sprinklers are designed to control or suppress fires at their
source, limiting fire growth and reducing the likelihood of severe
property damage and loss of life. Individual sprinklers normally activate
when exposed to sufficient heat rather than simply because smoke is
present.
3. Which sprinkler component is specifically designed to detect heat
and release water from an individual sprinkler?
A. Alarm check valve
B. Sprinkler operating element
C. Test connection
D. Main drain
B. Sprinkler operating element
The operating element, such as a glass bulb or fusible element, responds
to heat at a specified temperature and releases the sprinkler's water
,seal. This allows water to discharge only from sprinklers exposed to
sufficient heat.
4. What is the principal function of a wet-pipe sprinkler system?
A. Maintain the sprinkler piping filled with water under pressure
B. Maintain the sprinkler piping filled exclusively with compressed air
C. Supply water only after a fire department connection is operated
D. Keep the piping completely empty until a smoke detector operates
A. Maintain the sprinkler piping filled with water under pressure
A wet-pipe system contains water in the distribution piping at all times.
When a sprinkler activates, the operating element opens and
pressurized water immediately discharges through that sprinkler.
5. In which condition is a dry-pipe sprinkler system particularly
appropriate?
A. Areas where freezing temperatures could damage water-filled piping
B. Heated office areas maintained above freezing
C. Areas requiring only portable extinguishers
D. Buildings where no water supply is available
A. Areas where freezing temperatures could damage water-filled piping
Dry-pipe systems use pressurized air or nitrogen to hold water behind a
dry-pipe valve. They are commonly installed in spaces subject to freezing
because the water is normally kept out of the sprinkler piping until
system operation occurs.
6. What is the primary function of the dry-pipe valve?
, A. Reduce sprinkler discharge pressure at every sprinkler
B. Hold back the water supply until sufficient pressure conditions cause
the valve to operate
C. Automatically refill every sprinkler after activation
D. Measure the temperature of the protected space
B. Hold back the water supply until sufficient pressure conditions cause
the valve to operate
The dry-pipe valve separates the water supply from the normally air- or
nitrogen-filled sprinkler piping. When a sprinkler opens and system
pressure changes sufficiently, the valve trips and permits water to enter
the system piping.
7. What is a major characteristic of a preaction sprinkler system?
A. Water is always flowing through every sprinkler
B. Water admission to the sprinkler piping is controlled by a detection or
supervisory arrangement
C. It cannot be used where freezing is possible
D. It requires every sprinkler to contain a smoke detector
B. Water admission to the sprinkler piping is controlled by a detection or
supervisory arrangement
Preaction systems use a separate detection or control arrangement to
regulate water admission into the sprinkler piping. This configuration is
useful where accidental water discharge could cause substantial
damage, such as in certain data-processing or archival areas.
