1. What is the primary purpose of an access control system?
A. To provide general building illumination
B. To regulate and monitor entry to protected areas
C. To replace all fire alarm devices
D. To increase electrical service capacity
Answer: B. To regulate and monitor entry to protected areas
Rationale: An access control system is designed to determine who is
permitted to enter a controlled area and under what conditions. It can
use credentials such as cards, PINs, biometrics, or mobile devices and
can also record access events. It does not replace fire alarm, lighting,
or electrical distribution systems.
, 2. Which component typically verifies the credential presented by a
person at a controlled doorway?
A. Door closer
B. Card reader
C. Surge protector
D. Junction box
Answer: B. Card reader
Rationale: A card reader or other credential reader captures
information from the credential and sends it to the access control
system for authorization. The reader itself generally does not provide
the mechanical locking force; that function is performed by a lock or
locking device.
3. What is the main function of an access control panel?
A. To mechanically open every door
B. To process access information and control field devices
C. To supply building-wide lighting
D. To replace the fire alarm control unit
Answer: B. To process access information and control field devices
Rationale: The access control panel is the central processing
equipment that receives information from readers, door-position
,switches, request-to-exit devices, and other inputs. It then applies
programmed rules and controls outputs such as electric locks, alarms,
and relays.
4. Which device is commonly used to detect whether a door is
physically open or closed?
A. Door position switch
B. Card printer
C. Electric strike
D. Credential encoder
Answer: A. Door position switch
Rationale: A door position switch, often implemented with a magnetic
contact, reports the physical status of the door to the access control
system. This allows the system to identify conditions such as a door
being held open or forced open.
5. What is the purpose of a request-to-exit device?
A. To authorize visitors at the exterior entrance
B. To detect an authorized person leaving and allow the locking system
to release appropriately
C. To increase card-reader operating voltage
D. To replace the door-position switch
, Answer: B. To detect an authorized person leaving and allow the
locking system to release appropriately
Rationale: Request-to-exit devices allow the system to recognize
legitimate egress without generating a forced-door alarm. They may
use motion detection, push buttons, or other sensing technologies.
Proper operation is particularly important when electronic locking
devices are used.
6. Which credential is generally considered a biometric credential?
A. PIN
B. Proximity card
C. Fingerprint
D. Magnetic stripe card
Answer: C. Fingerprint
Rationale: Biometrics identify a person using a physical or behavioral
characteristic, such as a fingerprint, facial characteristic, iris pattern,
or voice. A PIN and card are possession or knowledge-based
credentials rather than biometric characteristics.
7. What does the term “fail-safe” generally mean when describing
an electrically controlled locking device?
