1. What is the primary purpose of a burglar alarm system?
A. To prevent fire hazards
B. To detect unauthorized entry and alert occupants or authorities
C. To control lighting systems
D. To manage HVAC systems
B. To detect unauthorized entry and alert occupants or authorities
Rationale: The main goal of a burglar alarm system is security. It is
designed to detect unauthorized access and alert the property owner
or a monitoring center. Fire or lighting control is handled by separate
systems.
2. Which component of an alarm system is responsible for detecting
motion?
A. Control panel
B. Keypad
, C. Motion sensor
D. Siren
C. Motion sensor
Rationale: Motion sensors detect movement within a protected area.
The control panel processes the signal, the keypad allows user input,
and the siren provides audible alerts.
3. What is the function of a control panel in an alarm system?
A. To detect smoke
B. To process signals from sensors and activate alarms
C. To physically secure doors
D. To provide video surveillance
B. To process signals from sensors and activate alarms
Rationale: The control panel is the central hub of the alarm system,
interpreting signals from sensors and triggering sirens, lights, or
notifications as appropriate.
4. Which type of sensor is most commonly used for detecting
window breakage?
A. PIR sensor
B. Glass-break sensor
C. Magnetic contact
D. Heat sensor
,B. Glass-break sensor
Rationale: Glass-break sensors detect the specific sound frequency of
breaking glass. Magnetic contacts detect door/window openings but

installations?
A. Coaxial cable
B. Twisted pair or Category 5/6
C. Fiber optics only
D. Open air wire
B. Twisted pair or Category 5/6
Rationale: Twisted pair or Cat5/6 cabling provides reliable, low-
interference connections for sensors and control panels, while coaxial
is mainly used for video and fiber optics for data transmission.
8. What is the purpose of a backup battery in an alarm system?
A. To reduce energy costs
B. To provide power during a main power outage
C. To control HVAC systems
D. To operate cameras only
B. To provide power during a main power outage
