Michigan (MI) Fire Suppression Exam | Latest
Verified Questions and Detailed Answers
OVERVIEW DESCRIPTION:
The Michigan Fire Suppression Exam certifies professionals to install, inspect, and maintain fire
suppression systems statewide. The exam covers NFPA 13, 14, and 2001 standards, Michigan
Mechanical Code, system hydraulics, installation techniques, and inspection procedures. Passing
grants licensure to legally work on sprinkler, standpipe, and specialized extinguishing systems in
commercial, residential, and industrial settings.
QUESTION 1
What is the minimum residual pressure required at the top of a standpipe system
during flow testing?
A. 25 psi
B. 50 psi
C. 100 psi
D. 150 psi
CORRECT ANSWER: C
EXPERT RATIONALE: NFPA 14 requires a minimum residual pressure of 100 psi at the
topmost outlet of a standpipe system when flowing the required flow rate.
QUESTION 2
According to NFPA 2001, what agent is commonly used in clean agent extinguishing
systems?
A. Carbon dioxide
B. Dry chemical powder
C. Halotron
D. Wet foam
CORRECT ANSWER: C

EXPERT RATIONALE: Halotron is a clean agent listed under NFPA 2001 that leaves no
residue and is electrically non-conductive, making it suitable for protecting sensitive
electronic equipment.
QUESTION 3
What is the maximum allowable spacing between branch lines in a sprinkler system
for a light hazard occupancy?
A. 10 feet
B. 12 feet
C. 15 feet
D. 20 feet
CORRECT ANSWER: C
EXPERT RATIONALE: NFPA 13 specifies that branch lines in light hazard occupancies
shall not exceed 15 feet of spacing to ensure adequate water coverage.
QUESTION 4
Which component prevents water from entering the dry pipe sprinkler system until a
sprinkler head activates?
A. Check valve
B. Dry pipe valve
C. Alarm valve
D. Flow switch
CORRECT ANSWER: B
EXPERT RATIONALE: The dry pipe valve holds back water under pressure, opening only
when air pressure drops due to sprinkler activation, allowing water to enter the piping.
QUESTION 5
Under the Michigan Mechanical Code, who is authorized to perform annual inspections
on fire suppression systems?
,3|Page
A. Any building owner
B. Certified fire suppression professionals
C. Local fire marshal only
D. General contractors
CORRECT ANSWER: B
EXPERT RATIONALE: Michigan law requires certified professionals with specific
training and licensing to perform legally recognized inspections on fire suppression
systems.
QUESTION 6
What is the maximum coverage area per sprinkler head in an ordinary hazard
occupancy?
A. 100 sq ft
B. 130 sq ft
C. 200 sq ft
D. 225 sq ft
CORRECT ANSWER: B
EXPERT RATIONALE: Ordinary hazard occupancies typically allow sprinkler coverage
up to 130 sq ft per head based on NFPA 13 spacing requirements.
QUESTION 7
Which NFPA standard covers the inspection, testing, and maintenance of water-based
fire protection systems?
A. NFPA 13
B. NFPA 14
C. NFPA 25
D. NFPA 72
CORRECT ANSWER: C
, 4|Page
EXPERT RATIONALE: NFPA 25 establishes the minimum requirements for the regular
inspection, testing, and maintenance of water-based fire protection systems.
QUESTION 8
When conducting a hydrostatic test on a sprinkler system, what pressure must be
maintained for how long?
A. 50 psi for 1 hour
B. 100 psi for 2 hours
C. 200 psi for 2 hours
D. 300 psi for 30 minutes
CORRECT ANSWER: C
EXPERT RATIONALE: NFPA 13 requires hydrostatic testing at 200 psi for two hours to
verify system integrity without pressure loss.
QUESTION 9
What is the purpose of an anti-freeze loop in a fire sprinkler system?
A. To prevent corrosion
B. To protect small areas subject to freezing
C. To increase water pressure
D. To filter debris from water
CORRECT ANSWER: B
EXPERT RATIONALE: Anti-freeze loops are installed in areas where freezing
temperatures could occur but where a full dry-pipe system is impractical.
QUESTION 10
Which type of extinguishing system is specifically designed for commercial cooking
operations?
A. Pre-action system
B. Wet chemical system
