1.
A service technician arrives at a commercial facility because the burglar
alarm has generated repeated false alarms during the previous week. The
customer reports that the system arms normally but produces an alarm
approximately 20 minutes later, even when the protected area is
unoccupied. What should be the technician's FIRST diagnostic
approach?
A. Immediately replace the control panel
B. Disable all motion detectors permanently
C. Review the event history and identify which zone or device is
generating the alarm
D. Increase the alarm delay on every zone
Answer: C. Review the event history and identify which zone or
device is generating the alarm
Rationale: Reviewing the event history provides objective information
about which zone, sensor, user action, or system condition is
associated with the recurring alarm. Once the problematic point is
identified, the technician can inspect the device, wiring, environmental
conditions, programming, and associated equipment. Replacing major
1
,equipment or changing programming without diagnosis can conceal
rather than solve the underlying problem.
2.
During preventive maintenance, a technician measures the standby
voltage of a 12-volt rechargeable alarm-system battery and finds that the
voltage appears normal while the system is idle. Which additional test is
most important for determining whether the battery can actually support
the system during an outage?
A. Check the color of the battery casing
B. Perform an appropriate battery load or capacity test
C. Disconnect every detector simultaneously
D. Increase the AC voltage supplied to the control panel
Answer: B. Perform an appropriate battery load or capacity test
Rationale: A battery can show an apparently acceptable open-circuit
voltage while having significantly reduced capacity. A load or capacity
test evaluates whether the battery can deliver the required current
without excessive voltage deterioration. Preventive maintenance
should therefore evaluate battery condition rather than relying solely
on a voltage reading.
3.
A magnetic door contact repeatedly reports an open condition even
though the door appears physically closed. The technician determines
that the magnet and reed switch have become misaligned because the
door has shifted slightly on its hinges. What is the most appropriate
corrective action?
2
,A. Replace the entire control panel
B. Realign the contact and magnet within the manufacturer's specified
operating distance
C. Remove the zone resistor
D. Increase the siren volume
Answer: B. Realign the contact and magnet within the
manufacturer's specified operating distance
Rationale: Magnetic contacts depend on proper alignment and
separation between the magnet and switching mechanism. Door
movement, loose hardware, or frame deformation can cause
intermittent or permanent open conditions. Correcting the mechanical
alignment is preferable to altering unrelated electrical or
programming characteristics.
4.
A customer states that the alarm system works correctly when
commercial power is available but shuts down shortly after a utility
outage. Which component should receive particular attention?
A. Door closer
B. Backup battery and charging circuit
C. Exterior siren grille
D. Motion detector lens only
Answer: B. Backup battery and charging circuit
Rationale: A properly maintained alarm system normally relies on
backup power when primary AC power fails. A weak battery, defective
charger, corroded connections, incorrect battery sizing, or excessive
standby load can cause premature shutdown. The technician should
evaluate both the battery and the charging system rather than
assuming the battery alone is defective.

A technician is servicing an alarm panel and discovers that several
conductors have loose terminals. What is the primary concern created by
loose terminal connections?
A. They always increase system security
B. They can produce intermittent faults, resistance changes, or complete
loss of circuit continuity
C. They automatically improve battery charging
D. They prevent all false alarms
Answer: B. They can produce intermittent faults, resistance
changes, or complete loss of circuit continuity
Rationale: Loose electrical connections can create intermittent opens,
increased resistance, voltage drops, arcing, or complete circuit failure.
These conditions can result in nuisance alarms, trouble signals,
communication failures, or loss of detection. Connections should be
inspected and secured according to manufacturer requirements.
6.
A motion detector repeatedly alarms in an area where no unauthorized
activity is occurring. Which condition should the technician investigate
BEFORE simply replacing the detector?
A. Environmental conditions such as HVAC airflow, sunlight,
temperature changes, or moving objects
B. The customer's office furniture color
C. The brand of telephone used by the customer
D. The customer's alarm password only
