1. A Tennessee alarm systems contractor is primarily responsible for
ensuring that an alarm installation is performed in accordance with
applicable licensing requirements, approved system designs,
manufacturer requirements, and applicable codes. Which action
best demonstrates proper contractor responsibility?
A. Installing equipment solely according to the customer's verbal
instructions
B. Allowing an unqualified person to independently perform all
technical work
C. Ensuring the installation, personnel, equipment, documentation, and
final system operation comply with applicable requirements
D. Disabling required protective devices whenever they cause nuisance
alarms
Answer: C
Rationale: A contractor's responsibility extends beyond simply
connecting equipment. Proper contracting practice requires attention
to applicable licensing requirements, qualified personnel,
manufacturer instructions, applicable codes, system documentation,
and functional testing. Customer preference cannot override
mandatory requirements.

, 2. A supervised alarm circuit is designed so that the control panel can
detect certain wiring faults rather than simply interpreting the
circuit as either open or closed. What is the principal purpose of
supervision?
A. To increase the audible volume of the alarm
B. To detect conditions such as open circuits, shorts, or tampering that
could compromise protection
C. To eliminate the need for backup batteries
D. To allow unlimited devices on one zone
Answer: B
Rationale: Supervision is a critical reliability feature. Depending on
the circuit design, resistors, end-of-line devices, or other supervision
methods allow the control unit to distinguish normal conditions from
wiring faults or tampering.
3. An installer is terminating a conventional initiating-device circuit
using an end-of-line resistor. Where should the resistor normally
be located when the system design requires end-of-line
supervision?
A. Inside the alarm control panel regardless of circuit configuration
B. At the first device on the circuit
C. At the electrically last device on the supervised circuit
D. At the monitoring station
Answer: C
Rationale: An end-of-line resistor is generally installed at the
electrically farthest point of the supervised circuit. Installing it inside
the panel can defeat the intended supervision because a break in the
field wiring may no longer be detected.
4. A normally closed magnetic door contact is connected to an alarm
zone. Under normal conditions, the door is closed and the contact
2
, remains closed. What normally happens when the protected door is
opened?
A. The circuit remains unchanged
B. The contact opens and the control panel recognizes the programmed
alarm condition
C. The resistor automatically increases its value
D. The monitoring station disconnects the telephone line
Answer: B
Rationale: A normally closed contact maintains circuit continuity
while the protected opening is closed. Opening the door changes the
circuit state, allowing the control panel to recognize an intrusion
condition when the zone is programmed accordingly.
5. A motion detector is installed in a room containing a large HVAC
supply vent. The installer notices that the detector occasionally
generates alarms when the heating or cooling system operates.
What is the most appropriate initial corrective action?
A. Increase the alarm siren volume
B. Replace every cable in the system
C. Evaluate detector placement and environmental conditions and
relocate or adjust the detector as appropriate
D. Permanently disable the motion detector
Answer: C
Rationale: PIR and other motion detectors can be affected by
environmental conditions, airflow, temperature changes, sunlight, and
improper placement. The correct approach is to investigate the
environmental cause and correct installation or programming rather
than simply disabling protection.
6. What is the principal function of an alarm control panel?
3
, A. To serve only as a battery charger
B. To receive, process, supervise, and respond to signals from system
devices according to programmed logic
C. To physically lock every door in the building
D. To replace all detection devices
Answer: B
Rationale: The control panel is the central processing component of
many alarm systems. It receives signals from initiating devices,
supervises circuits, operates notification appliances, communicates
alarm events, and controls system functions according to its
programming.
7. A commercial alarm system contains numerous initiating devices,
notification appliances, communicators, and auxiliary equipment.
Before installation, what is one of the most important reasons to
calculate the electrical load?
A. To determine the color of the enclosure
B. To ensure the power supply and standby batteries can adequately
support connected equipment
C. To determine the customer's insurance premium automatically
D. To eliminate the need for circuit supervision
Answer: B
Rationale: Equipment load calculations help determine whether the
control panel, auxiliary power supplies, batteries, and wiring can
safely provide required current under normal and standby conditions.
Insufficient capacity can cause system failures or reduced standby
duration.
8. A 12-volt alarm circuit has a device drawing 0.5 ampere. Using
Ohm's law, what approximate resistance would correspond to that
current at 12 volts?
