1. During an inspection of a conventional fire alarm system, an
inspector discovers that a manual fire alarm box has been installed
behind a permanently fixed display cabinet. What is the primary
concern?
A. The cabinet may interfere with the alarm system's standby battery
calculations
B. The manual fire alarm box may not be readily accessible for
emergency activation
C. The cabinet could increase the resistance of the initiating circuit
D. The manual box will automatically transmit a false alarm
Answer: B. The manual fire alarm box may not be readily accessible
for emergency activation
Rationale: A manual fire alarm box must be readily accessible so
occupants can quickly initiate an alarm. Obstructions such as
permanently installed cabinets, displays, equipment, or storage can
delay activation during an emergency. The issue is primarily
accessibility and visibility, not battery capacity or circuit resistance.
2. An inspector opens a fire alarm control panel and discovers that
the system's batteries are present but are not secured against
movement. Why should this condition receive attention?
1
,A. Unsecured batteries can alter detector sensitivity
B. Battery movement can damage connections and compromise the
emergency power source
C. Unsecured batteries automatically disable notification appliances
D. Battery movement increases the voltage supplied by the utility
Answer: B. Battery movement can damage connections and
compromise the emergency power source
Rationale: Fire alarm batteries must be properly installed and secured.
Movement can place mechanical stress on terminals, conductors, and
connectors, potentially resulting in an open circuit or loss of standby
power. Because the batteries provide required emergency operating
power, improper securing can compromise system reliability.
3. During inspection, an inspector measures the voltage at a
notification appliance circuit and finds that voltage at the beginning
of the circuit is substantially higher than voltage at the end of a long
circuit. What condition should the inspector investigate most
closely?
A. Excessive voltage drop
B. Excessive detector sensitivity
C. Incorrect smoke detector spacing
D. Improper manual pull station height
Answer: A. Excessive voltage drop
Rationale: Voltage drop occurs as current travels through circuit
conductors and connected loads. Excessive voltage drop can cause
notification appliances at the far end of a circuit to operate improperly
or fail to achieve their required performance. Conductor size, circuit
length, appliance loading, and available voltage should therefore be
evaluated.

,4. A fire alarm control unit is supplied from a branch circuit that
also supplies several convenience receptacles. What is the inspector's
principal concern?
A. The receptacles will increase smoke detector sensitivity
B. The fire alarm supply may be interrupted by unrelated equipment or
unauthorized disconnection
C. The fire alarm panel will automatically increase its output voltage
D. The notification appliances will become addressable
Answer: B. The fire alarm supply may be interrupted by unrelated
equipment or unauthorized disconnection
Rationale: Fire alarm control equipment requires a dependable power
source. The branch circuit supplying the fire alarm system should be
appropriately dedicated, identified, and protected so that unrelated
equipment does not inadvertently disconnect or overload the supply.
5. An inspector discovers that several fire alarm conductors have
been spliced using ordinary wire nuts inside an accessible electrical
box. What should determine whether the installation is acceptable?
A. Whether the wire nuts are the same color as the fire alarm panel
B. Whether the splicing method and enclosure are permitted for the
particular fire alarm circuit and installation
C. Whether the conductors are copper
D. Whether the fire alarm panel has a digital display
Answer: B. Whether the splicing method and enclosure are
permitted for the particular fire alarm circuit and installation
Rationale: Fire alarm circuit splices must be made using methods and
materials appropriate for the circuit and applicable installation
requirements. The inspector should verify the enclosure, wiring
3
, method, conductor compatibility, accessibility, mechanical protection,
and applicable listing or code requirements rather than assuming that
an ordinary wire nut is automatically acceptable or unacceptable.
6. During a fire alarm inspection, the inspector finds a notification
appliance whose candela setting does not correspond to the
documented design. What is the most appropriate action?
A. Ignore it because all strobes produce approximately the same light
output
B. Verify the required visual notification performance and correct the
appliance or setting if necessary
C. Replace every appliance in the building
D. Disable the visual notification circuit
Answer: B. Verify the required visual notification performance and
correct the appliance or setting if necessary
Rationale: Visual notification appliances must provide the required
light output for the space in which they are installed. Incorrect
candela settings can result in insufficient notification or inappropriate
system performance. The inspector should compare the installed
setting with the approved design and applicable requirements.
7. What is the principal electrical purpose of an end-of-line device
on a conventional supervised fire alarm initiating circuit?
A. To increase circuit voltage
B. To permit supervision of circuit continuity and detect certain open-
circuit conditions
C. To amplify smoke detector signals
D. To convert a conventional circuit into an addressable circuit
