1. What is the primary purpose of a burglar alarm system?
A. To provide electrical power to a building
B. To control the building's HVAC system
C. To detect unauthorized entry or specified security conditions
D. To regulate emergency lighting
Answer: C. To detect unauthorized entry or specified security
conditions
Rationale: A burglar alarm system is designed to detect conditions
associated with unauthorized access, intrusion, or other programmed
security events and to initiate an appropriate alarm or notification
response.
, 2. Which component is commonly used to detect the opening of a
protected door or window?
A. Smoke detector
B. Magnetic contact
C. Transformer
D. Surge protector
Answer: B. Magnetic contact
Rationale: Magnetic contacts use a magnet and switching mechanism
to monitor whether a door or window is open or closed. They are among
the most common perimeter protection devices.
3. What is the primary function of an alarm control panel?
A. Convert AC power into utility power
B. Process signals from security devices and control system operation
C. Provide telephone service
D. Replace every field device in the system
Answer: B. Process signals from security devices and control system
operation
Rationale: The control panel is the central processing unit of a burglar
alarm system. It receives signals from initiating devices, evaluates
,programmed conditions, activates notification or communication
functions, and supervises system components.
4. Which device is commonly used to detect movement within a
protected area?
A. Motion detector
B. Door closer
C. Circuit breaker
D. Junction box

7. What does a normally closed alarm contact generally do when the
protected circuit is opened?
A. It remains electrically unchanged
B. It changes state and can cause the panel to recognize an alarm or
trouble condition
C. It increases the circuit voltage automatically
D. It disconnects the building's main electrical service
