new fire sprinkler system?
,A) The installing contractor's lead designer.
B) The project's general contractor.
C) The Authority Having Jurisdiction (AHJ).
D) The building owner's insurance carrier.
Answer: C The Authority Having Jurisdiction (AHJ), which is typically the local fire marshal or building
official, must review and approve all design documents before installation begins.
5. A project involves extending an existing sprinkler system in a Phoenix office building. What is the
contractor's first legal responsibility regarding existing system conditions?
A) Perform a forward flow test to verify water supply.
B) Review the most recent annual inspection report (NFPA 25).
C) Verify the existing system is in service and notify the AHJ of the planned work.
D) Assume the existing system is compliant and proceed.
Answer: C Before altering any existing fire protection system, the contractor must verify it is operational
and must obtain the necessary permits and notifications, which includes informing the AHJ of the
planned modification.
6. In Arizona, a C16 contractor is permitted to perform work on which of the following systems?
A) Standpipe and hose systems only.
B) Fire pumps, sprinklers, standpipes, and fire alarm control panels.
C) Fixed foam suppression systems for industrial hazards.
D) All of the above, as they fall under the classification's broad scope.
Answer: D The C16 classification encompasses the installation, maintenance, alteration, and repair of
automatic fire sprinkler systems, standpipe systems, fire pump and water storage tank systems, and
fixed fire suppression systems (including foam and chemical).
7. When is a building permit NOT required for fire protection system work in Arizona?
A) Routine maintenance as defined by NFPA 25.
B) Replacement of a sprinkler head with an identical type and temperature rating.
C) Installation of a new control valve.
D) Both A and B are typically exempt from permitting.
,Answer: D Most jurisdictions, following the IFC, do not require permits for routine maintenance or the
like-for-like replacement of sprinklers (provided it doesn't exceed a small percentage of heads).
Installation of a new valve generally requires a permit.
8. For a new high-rise building in Tucson, the fire protection systems must be designed to meet the
requirements of:
A) NFPA 13 only.
B) The Arizona State Fire Code and the International Building Code.
C) Local city ordinances only, as they supersede state code.
D) The insurance carrier's requirements, which are always stricter.
Answer: B The project must comply with the adopted state codes, which include the Arizona State Fire
Code (based on IFC) and the International Building Code (IBC) for building construction type and
occupancy hazards.
9. The required working plans for a sprinkler system submittal must include all of the following EXCEPT:
A) Manufacturer's cut sheets for all listed equipment.
B) A detailed floor plan showing all sprinkler locations and pipe sizes.
C) The contractor's license number and RME information.
D) A complete hydraulic calculation for the design area.
Answer: C While contractor information is required on permit applications, the working plans
themselves (the drawings and calcs) do not typically include the license number. They must show the
designer's information.
10. What is the standard used for the inspection, testing, and maintenance of water-based fire
protection systems?
A) NFPA 13
B) NFPA 20
C) NFPA 25
D) NFPA 72
Answer: C NFPA 25, Standard for the Inspection, Testing, and Maintenance of Water-Based Fire
Protection Systems, is the governing standard.
, 11. A fire pump installed as part of a C16 project must be installed in accordance with:
A) NFPA 20 and the pump manufacturer's instructions.
B) The local water utility's specifications only.
C) NFPA 13, as it is part of the sprinkler system.
D) Underwriters Laboratories (UL) standards.
Answer: A NFPA 20, Standard for the Installation of Stationary Pumps for Fire Protection, is the primary
standard, and listed equipment must be installed per its listing (manufacturer's instructions).
12. The minimum required residual pressure at the base of a standpipe in a Class I system for the highest
outlet is:
A) 65 psi
B) 100 psi
C) 75 psi
D) 150 psi
Answer: B Per NFPA 14, the water supply must provide 500 GPM at a residual pressure of 100 psi at the
topmost outlet for Class I standpipe systems.
13. What is the primary purpose of an antifreeze loop in a fire sprinkler system?
A) To prevent water from freezing in a small, heated section of pipe.
B) To protect unheated areas like loading docks or attics from freezing.
C) To cool the main water supply during summer months.
D) To act as a pre-action system for computer rooms.
Answer: B Antifreeze systems are used in specific, localized areas of a building that cannot be
maintained above 40°F (4°C). Their use is heavily restricted by NFPA 13 due to performance and
environmental concerns.
14. A "listed" device or piece of equipment in fire protection means:
A) It is approved by the local fire marshal.
