Question 1: A two-wire Class B circuit has 10 smoke detectors on it. A Class B
circuit will typically have an end-of-line device on the last detector in the circuit.
The end-of-line device is usually a _____.
A) Capacitor
B) Resistor
C) Diode
D) Transformer
Correct Answer: B
Rationale: A Class B circuit uses an end-of-line resistor to supervise the circuit for
integrity. The resistor allows the panel to detect opens or shorts in the wiring .
Question 2: Smoke detectors installed in air duct systems are normally used to
control spreading smoke.
A) True
B) False
Correct Answer: A
Rationale: Duct smoke detectors are primarily installed to prevent the spread of smoke
through HVAC systems by initiating fan shutdown, damper closure, or other smoke
control functions .
,Question 3: A smoke detector installed in an air duct system is permitted to be
used as a substitute for open area protection.
A) True
B) False
Correct Answer: B
Rationale: Duct detectors cannot substitute for open area protection. Areas in ducts,
below floors, and above ceilings are considered separate areas requiring their own
detection .
Question 4: If control circuits are used to shut down elevator power, the control
circuits are not required to be monitored for the presence of operating voltage.
A) True
B) False
Correct Answer: B
Rationale: Control circuits used for elevator power shutdown must be monitored for
the presence of operating voltage to ensure supervisory integrity .
Question 5: According to the Ohio Fire Code, in a covered mall building exceeding
50,000 ft² in area, a(n) ______ shall be provided.
A) Emergency Voice/Alarm Communications System
B) Manual pull station system
C) Waterflow alarm system
D) Local only alarm system
Correct Answer: A
Rationale: Covered mall buildings exceeding 50,000 square feet require an Emergency
Voice/Alarm Communications System to ensure effective evacuation communication .
,Question 6: A detector that is capable of resetting itself when the heat in the area
drops below the detector's set point is called a:
A) Nonrestorable heat detector
B) Restorable heat detector
C) Rate-of-rise detector
D) Fusible link detector
Correct Answer: B
Rationale: A restorable heat detector automatically resets when the temperature drops
below its set point after activation .
Question 7: Any alarm that occurs that is not the result of a potentially hazardous
condition is known as:
A) False alarm
B) Unwanted alarm
C) Nuisance alarm
D) Supervisory alarm
Correct Answer: B
Rationale: An unwanted alarm is defined as any alarm that occurs that is not the result
of a potentially hazardous condition .
Question 8: Smoke detectors must be functionally tested:
A) Monthly
B) Quarterly
C) Annually
D) Every 5 years
, Correct Answer: C
Rationale: NFPA 72 requires smoke detectors to be functionally tested on an annual
basis .
Question 9: Smoke alarms or smoke detectors are required at what locations?
A) In each sleeping room only
B) Outside each sleeping room only
C) On each level only
D) In each sleeping room, outside each sleeping room, and on each level
Correct Answer: D
Rationale: Smoke alarms are required in every sleeping room, outside each sleeping
area, and on every level of the home including basements .
Question 10: A Class X circuit is a redundant pathway that only applies to
addressable fire alarm signaling device circuits.
A) True
B) False
Correct Answer: A
Rationale: Class X circuits provide a redundant pathway, allowing continued
communication even with a single open or short circuit, and applies specifically to
addressable systems .
Question 11: When installing a smoke detector for door release service and the
depth of the wall above the door is greater than 24 inches on one side only, we
must install _____ ceiling-mounted detector(s) on the higher side or ____ wall-
mounted detector(s) (one on each side of the doorway).
A) 1, 2
B) 2, 1
