➢ Question 1
A technician is testing a waterflow switch on a sprinkler system in a commercial
building. According to NFPA 72, how often shall waterflow devices be tested?
A) Monthly
B) Quarterly
C) Semi-annually
D) Annually
-CORRECT ANSWER- Annually
Rationale: According to NFPA 72, waterflow devices shall be tested annually.
➢ Question 2
A wall-mounted visible notification appliance is being installed in a room where the
finished ceiling height is 6.75 feet. What is the maximum distance from the ceiling that
this appliance may be mounted?
A) 6 inches
B) 12 inches
C) 18 inches
D) 24 inches
-CORRECT ANSWER- 12 inches
*Rationale: At a ceiling height of 6.75 feet, the maximum mounting distance from
the ceiling for a wall-mounted visible appliance is 12 inches.*
➢ Question 3
On a conventional fire alarm system, where is the end-of-line resistor located for a Class
, B initiating circuit?
A) At the fire alarm control panel terminals
B) At the device physically farthest from the panel
C) At the first device on the circuit
D) At the last device before the panel returns
-CORRECT ANSWER- at the device physically farthest from the panel
Rationale: For a Class B circuit, the end-of-line resistor is located at the device
physically farthest from the control panel to supervise the circuit for opens.
➢ Question 4
You are reviewing fire alarm drawings and need to identify the symbol for a heat detector.
Which symbol represents a heat detector based on standard fire alarm symbols?
A) A circle with a "D" inside
B) A circle with an "S" inside
C) A circle with a "H" inside or a circle with a dot pattern
D) A square with a bell symbol
-CORRECT ANSWER- C
Rationale: The standard symbol for a heat detector is typically shown as a circle with a
"H" designation or specialized heat detector symbol.
➢ Question 5
A projected beam-type smoke detector is being installed on a peaked ceiling. Within what
maximum distance from the peak must this detector be installed?
A) 1 foot
B) 2 feet
C) 3 feet
D) 4 feet
-CORRECT ANSWER- 3 feet
*Rationale: On a peaked ceiling, projected beam-type smoke detectors must be
installed within 3 feet of the peak.*
➢ Question 6
Which one of the following examples represents a parallel electrical circuit in a fire alarm
system?
, A) Three smoke detectors connected in a single loop returning to the panel
B) A single heat detector connected to two wires
C) Four pull stations connected end-to-end
D) A notification circuit with devices wired in series
-CORRECT ANSWER- a single heat detector
Rationale: A single heat detector represents a parallel circuit because it provides a
single path but the device is electrically in parallel with the panel's supervision circuit.
➢ Question 7
A technician is inspecting an extension cord before use on a job site. According to
OSHA, which electrical cord is considered safe to use?
A) One with a repaired taped splice
B) One that is free of cuts
C) One with the ground prong removed
D) One with minor fraying on the insulation
-CORRECT ANSWER- one that is free of cuts
Rationale: OSHA requires that electrical cords be free of cuts, damage, and exposed
conductors to be considered safe for use.
➢ Question 8
In a conventional fire alarm system, which component serves as a contact device that is
normally open?
A) Smoke detector
B) Pull station
C) High- or low-air pressure switch
D) Waterflow switch
-CORRECT ANSWER- high- or low-air pressure switch
Rationale: A high- or low-air pressure switch in a conventional system serves as a
normally open contact device that closes when pressure thresholds are exceeded.
➢ Question 9
Cables are being installed under a corrugated metal roof deck. What is the minimum
distance these cables must be located from the roof deck?
A) 1/2 inch
, B) 1 inch
C) *1 1/2 inches*
D) 2 inches
-CORRECT ANSWER- *1 1/2 inches (1.50)*
Rationale: Cables installed under a corrugated metal roof deck must be located at least
1.5 inches from the roof deck to prevent damage and overheating.
➢ Question 10
After the fire alarm system installation has been completed and the alarm contractor has
performed the acceptance test, at what interval should system smoke detectors undergo
functional testing?
A) Monthly
B) Quarterly
C) Semi-annually
D) Annually
-CORRECT ANSWER- Annually
Rationale: After acceptance testing, system smoke detectors shall undergo functional
testing annually per NFPA 72.
➢ Question 11
Fire alarm cable will be run exposed inside a building riser. Which three types of cable
are acceptable for this installation? (Choose three.)
A) CMP (Plenum)
B) FPLR (Riser)
C) FPL (General purpose)
D) CM (Communications) only
-CORRECT ANSWER- CMP, FPLR, FPL
Rationale: For exposed riser installations, CMP (plenum), FPLR (riser), and FPL
(general purpose) cables are all acceptable based on their fire ratings.
➢ Question 12
When working with conduit, fasteners shall be driven into which type of material to
ensure secure mounting?
A) Drywall without backing
