1. What is the primary purpose of an automatic sprinkler system?
A. To eliminate all fire hazards before ignition
B. To provide building occupants with unlimited water for firefighting
C. To control or suppress a developing fire until further firefighting
action can occur
D. To prevent smoke from entering occupied areas
Answer: C. To control or suppress a developing fire until further
firefighting action can occur
Rationale: Automatic sprinklers are designed primarily to control or
suppress fires in their early stages. Individual sprinkler heads typically
operate when exposed to sufficient heat, allowing water to be
discharged directly into the fire area. Sprinkler systems are not
,intended to eliminate every fire hazard or replace all other fire-
protection measures.
2. Which component detects heat and automatically opens to
discharge water from an individual sprinkler?
A. Alarm check valve
B. Sprinkler head
C. Fire department connection
D. Waterflow switch
Answer: B. Sprinkler head
Rationale: The sprinkler head contains a heat-responsive operating
element, such as a fusible link or glass bulb. When the surrounding
temperature reaches the sprinkler's rated operating temperature, the
element releases and permits water to discharge. A waterflow switch
detects movement of water but does not normally initiate individual
sprinkler discharge.
3. In a wet-pipe sprinkler system, what is normally contained in the
piping above the sprinkler control valve?
A. Compressed air only
B. Water under pressure
,C. Carbon dioxide
D. Foam concentrate
Answer: B. Water under pressure
Rationale: A wet-pipe system keeps water in the distribution piping at
all times. When a sprinkler operates, pressurized water immediately
flows through the open sprinkler. Wet systems are commonly used
where freezing temperatures are not expected.
4. Which sprinkler system is generally used where portions of the
system are exposed to freezing temperatures?
A. Wet-pipe system
B. Dry-pipe system
C. Deluge system
D. Standpipe-only system
Answer: B. Dry-pipe system
Rationale: A dry-pipe system normally contains pressurized air or
nitrogen in the piping rather than water. When a sprinkler operates,
the dry-pipe valve opens and allows water into the system. This
arrangement helps protect piping located in areas subject to freezing.
5. What is a principal characteristic of a deluge sprinkler system?
, A. Sprinklers are normally filled with water
B. Only the sprinkler closest to the fire can discharge
C. Open sprinklers or nozzles can discharge water simultaneously when
the deluge valve operates
D. The system cannot be connected to a detection system
Answer: C. Open sprinklers or nozzles can discharge water
simultaneously when the deluge valve operates
Rationale: Deluge systems use open sprinklers or nozzles. Water is
normally held back by a deluge valve, which is released by an
appropriate detection or actuation system. Once the valve opens,
water flows through all open outlets, providing rapid application over
the protected area.
6. What is the primary function of a fire department connection
(FDC)?
A. To drain the sprinkler system
B. To allow firefighters to supplement the sprinkler system with an
external water supply
C. To detect a fire
D. To regulate room temperature
Answer: B. To allow firefighters to supplement the sprinkler system
with an external water supply
