SYSTEMS EXAM STUDY GUIDE
QUESTIONS AND ANSWERS
1. A Master Pressure Reducing Valve (PRV) must be inspected at what minimum frequency to
ensure it is not leaking or damaged?
A. Weekly
B. Monthly
C. Quarterly
D. Annually
Answer: C
Conceptual Explanation: According to NFPA 25 standards adopted by the FDNY, Master
Pressure Reducing Valves are required to be inspected quarterly to ensure they are in good
condition and not leaking.
2. When a sprinkler system is found to have a ‘Critical Deficiency’, the condition must be
corrected within what time frame?
A. Immediately
,B. Within 24 hours
C. Within 30 days
D. During the next annual inspection
Answer: C
Conceptual Explanation: While impairments require immediate action, critical

A. Silver
B. Red
C. Green
D. Yellow
Answer: A

4. In a pressure tank, what is the standard ratio of water to compressed air?
A. 1/3 water to 2/3 air
B. 1/2 water to 1/2 air
, C. 2/3 water to 1/3 air
D. 3/4 water to 1/4 air

A. The system is fully operational.
B. A non-critical deficiency exists.
C. A critical deficiency exists.
D. The system is impaired and out of service.
Answer: A
Conceptual Explanation: A white tag indicates that the system has been inspected and
found to be in satisfactory condition.
6. How often should the waterflow alarm devices (like pressure switches or vane-type
