Section One: Questions 1–100
1. Which agency administers the Journeyman Sprinkler (JS) licensing exam in New Mexico?
A) New Mexico State Fire Marshal
B) New Mexico Construction Industries Division (CID)
C) PSI Services
D) National Fire Protection Association (NFPA)
Correct Answer: C) PSI Services
Rationale: The New Mexico Journeyman Sprinkler exam is administered by PSI Services, an
independent testing provider contracted by the state. The Construction Industries Division (CID)
oversees licensing and sets requirements, while PSI handles the logistics of test delivery and scoring.
2. What is the minimum passing score required for the New Mexico Journeyman Sprinkler exam?
A) 70%
B) 75%
C) 80%
D) 85%
Correct Answer: A) 70%
Rationale: Based on available exam information for New Mexico fire protection and sprinkler
licensing, candidates must achieve a minimum passing score of 70%. This percentage is typical for
trade licensing exams in New Mexico, ensuring candidates demonstrate adequate competency
without imposing an unnecessarily high threshold.
3. Which of the following is a key feature of the New Mexico Journeyman Sprinkler examination?
A) Closed book format
B) Open book format
C) Computer-adaptive testing
D) Oral examination
Correct Answer: B) Open book format
Rationale: The New Mexico JS Journeyman Sprinkler exam is an open-book exam, allowing candidates
to reference approved code books and standards during testing. This reflects the practical nature of
the trade, where professionals are expected to know how to locate and apply code requirements
rather than memorize every provision.
,4. The MS-12 Fire Protection Systems exam, a related New Mexico certification, allows candidates
to bring which of the following reference materials?
A) Any published textbook
B) Only the NFPA 13 standard
C) Specific, bound NFPA codes and standards
D) A personal notebook of study notes
Correct Answer: C) Specific, bound NFPA codes and standards
Rationale: For the MS-12 exam, candidates may bring specifically listed NFPA standards that must be
bound and may be pre-highlighted or indexed. This ensures all candidates use the same reference
editions and prevents the use of unauthorized or unverified materials that could compromise exam
integrity.
5. What is the primary purpose of the Journeyman Sprinkler license in New Mexico?
A) To design commercial fire protection systems
B) To install, maintain, and repair fire sprinkler systems
C) To inspect buildings for fire code compliance
D) To manufacture fire sprinkler equipment
Correct Answer: B) To install, maintain, and repair fire sprinkler systems
Rationale: A Journeyman Sprinkler license qualifies a professional to perform the installation,
maintenance, and repair of fire sprinkler systems under the supervision of a licensed contractor.
Design work typically requires higher-level engineering or contractor credentials, while inspection is
often a separate municipal function.
6. Which NFPA standard is the primary reference for the installation of fire sprinkler systems?
A) NFPA 13
B) NFPA 14
C) NFPA 20
D) NFPA 25
Correct Answer: A) NFPA 13
Rationale: NFPA 13 is the definitive standard governing the installation of fire sprinkler systems. It is
the core reference for any sprinkler licensing exam and covers system components, design criteria,
spacing, and hydraulic requirements. NFPA 14 covers standpipes, NFPA 20 covers fire pumps, and
NFPA 25 covers inspection, testing, and maintenance.
7. Which NFPA standard specifies requirements for the inspection, testing, and maintenance of
water-based fire protection systems?
A) NFPA 13
B) NFPA 14
C) NFPA 20
D) NFPA 25
Correct Answer: D) NFPA 25
, Rationale: NFPA 25 is the standard for Inspection, Testing, and Maintenance (ITM) of water-based fire
protection systems. This standard establishes frequency and procedures for ensuring systems remain
operational. NFPA 25 is often tested separately from installation standards because ITM is critical for
life safety.
8. What is the most common type of fire sprinkler system, where water is kept under pressure at
all times?
A) Dry pipe system
B) Pre-action system
C) Wet pipe system
D) Deluge system
Correct Answer: C) Wet pipe system
Rationale: A wet pipe system is the simplest and most common type, containing water under pressure
at all times. Water discharges immediately when a sprinkler head activates, making it highly reliable
and cost-effective for heated environments. Dry pipe and pre-action systems are used where freezing
or accidental discharge is a concern.
9. A dry pipe sprinkler system is typically used in which application?
A) Office buildings with high fire loads
B) Unheated warehouses in cold climates
C) Museum storage areas with valuable artifacts
D) Industrial facilities with flammable liquids
Correct Answer: B) Unheated warehouses in cold climates
Rationale: Dry pipe systems are specifically designed for areas subject to freezing temperatures, such
as unheated warehouses or attic spaces. The system piping contains compressed air or nitrogen,
holding water back at the valve. This prevents water from freezing and bursting pipes, which would
disable the system.
10. In a dry pipe valve, the clapper is held in the closed position by:
A) Water pressure
B) Spring tension
C) Air pressure in the system piping
D) An electric solenoid
Correct Answer: C) Air pressure in the system piping
Rationale: The dry pipe valve uses a clapper mechanism held closed by compressed air pressure in the
system piping. When a sprinkler opens, air pressure drops, allowing the clapper to release. This
design uses the pressure differential principle, balancing water pressure below the clapper with air
pressure above it.
11. Which type of system has open sprinklers and activates all heads simultaneously upon
detection of a fire?
A) Wet pipe system
B) Dry pipe system
