1. Which type of sensor detects changes in infrared energy emitted
by objects?
A. Magnetic contact
B. Ultrasonic
C. Passive infrared (PIR)
D. Microwave
C. Passive infrared (PIR)
PIR sensors detect changes in infrared energy from moving
objects, commonly used in motion detection.
2. What is the main purpose of an access control system?
A. Detect smoke
B. Monitor temperature
C. Restrict and monitor entry to secure areas
D. Record video
C. Restrict and monitor entry to secure areas
Access control systems manage who can enter or exit defined
areas, enhancing security.
,3. Which component converts AC power to DC for security devices?
A. Transformer
B. Rectifier
C. UPS
D. Alarm panel
B. Rectifier
A rectifier converts AC to DC, which is required for most security
electronics.
4. In CCTV systems, what does PTZ stand for?
A. Power, Transmission, Zoom
B. Pan, Tilt, Zoom
C. Passive, Thermal, Zoom
D. Position, Timing, Zone
B. Pan, Tilt, Zoom
PTZ cameras can pan, tilt, and zoom, allowing flexible
surveillance coverage.
5. Which type of alarm system wiring is most resistant to tampering?
A. Analog
B. Wireless
C. Supervised (end-of-line resistor)
D. Open-circuit
C. Supervised (end-of-line resistor)
Supervised circuits detect wiring tampering by monitoring the
loop for continuity.
6. What is the function of a DVR in a security system?
A. Detect motion
B. Record video from cameras
C. Control access points
D. Power devices
, B. Record video from cameras
DVRs store video footage from analog cameras for review and
evidence.
7. What voltage is commonly used to power CCTV cameras?
A. 5V AC
B. 12V DC
C. 24V AC
D. 120V DC
B. 12V DC
Most CCTV cameras operate on 12V DC, though some systems
use 24V AC.
8. Which is a primary benefit of IP cameras over analog cameras?
A. Higher power consumption
B. Analog signal transmission
C. Network connectivity and remote access
D. Requires coaxial cable
C. Network connectivity and remote access
IP cameras transmit digital video over a network, enabling
remote monitoring and integration with IT systems.
9. What type of fire alarm device detects smoke particles?
A. Heat detector
B. Ionization smoke detector
C. Carbon monoxide detector
D. Magnetic sensor
B. Ionization smoke detector
Ionization detectors sense smoke particles, triggering alarms
early in flaming fires.
10. Which battery type is commonly used in security backup
systems?
, A. Lithium-ion
B. Lead-acid
C. Alkaline
D. Nickel-cadmium
B. Lead-acid
Sealed lead-acid batteries provide reliable backup power for
alarm and access control systems.
11. What does a “normally closed” (NC) circuit indicate in alarm
systems?
A. The circuit is open when inactive
B. The circuit is closed when inactive
C. The circuit bypasses the sensor
D. The circuit is wireless
B. The circuit is closed when inactive
In NC circuits, continuity exists when no alarm condition is
present; breaking the circuit triggers an alarm.
12. Which device detects glass breaking?
A. PIR sensor
B. Vibration sensor
C. Acoustic sensor
D. Microwave sensor
C. Acoustic sensor
Glass break detectors sense the sound frequency of breaking
glass, triggering alarms.
13. What is the main purpose of a UL listing on security
equipment?
A. Aesthetic compliance
B. Energy efficiency
C. Safety and reliability verification
