1. What is the primary purpose of an electronic security
system?
A. Increase building energy efficiency
B. Protect people, property, and assets
C. Replace all security personnel
D. Eliminate the need for locks
Correct Answer: Protect people, property, and assets
Rationale: The primary purpose of a security system is
to detect, deter, delay, document, or respond to
unauthorized activity and other threats to people and
property.
2. Which component is generally considered the central
processing unit of an intrusion alarm system?
A. Door contact
B. Motion detector
C. Control panel
D. Siren
,Correct Answer: Control panel
Rationale: The control panel receives signals from
initiating devices, processes those signals, supervises
circuits, and activates appropriate outputs.
3. What does PIR stand for?
A. Primary Intrusion Relay
B. Passive Internal Relay
C. Passive Infrared
D. Programmable Intrusion Receiver
Correct Answer: Passive Infrared
Rationale: A PIR detector senses changes in infrared
energy caused by movement within its detection
pattern.
4. Which device is commonly used to detect the opening
of a protected door?
A. PIR detector
B. Magnetic contact
C. Smoke detector
D. Camera
Correct Answer: Magnetic contact
Rationale: A magnetic contact uses a magnet and switch
arrangement to monitor whether a door, window, or
other opening is open or closed.
5. What is the main purpose of an end-of-line resistor in
a supervised alarm circuit?
A. Increase speaker volume
B. Increase camera resolution
,C. Supervise the wiring for faults or tampering
D. Supply emergency lighting
Correct Answer: Supervise the wiring for faults or
tampering
Rationale: Properly installed end-of-line resistance
allows the control panel to recognize abnormal circuit
conditions such as opens or shorts.
6. Which device is designed to detect physical impact or
vibration on a protected surface?
A. PIR
B. Smoke detector
C. Shock sensor
D. Card reader
Correct Answer: Shock sensor
Rationale: Shock or vibration sensors can detect
impacts associated with attempts to break glass, force
doors, or attack protected structures.
7. What is a major advantage of dual-technology motion
detection?
A. It eliminates all false alarms
B. It requires no power
C. It can reduce false alarms by using two detection
technologies
D. It eliminates the control panel
Correct Answer: It can reduce false alarms by using two
detection technologies
Rationale: Dual-technology detectors may require
compatible signals from two technologies before
generating an alarm, helping reduce nuisance
activations.
, 8. What is the primary purpose of an alarm system
battery backup?
A. Increase camera resolution
B. Maintain system operation during a primary power
failure
C. Increase network speed
D. Replace the control panel
Correct Answer: Maintain system operation during a
primary power failure
Rationale: Backup batteries provide standby power so
critical security functions can continue when normal AC
power is interrupted.
9. What does CCTV stand for?
A. Central Camera Transmission Television
B. Controlled Communication Television
C. Closed-Circuit Television
D. Computerized Camera Tracking Technology
Correct Answer: Closed-Circuit Television
Rationale: CCTV refers to video systems in which signals
are distributed to designated equipment rather than
broadcast publicly.
10. What is the primary function of a DVR?
A. Supply power to cameras
B. Record video from compatible cameras
C. Unlock doors
D. Detect smoke
Correct Answer: Record video from compatible cameras
