1. A commercial access control system is being designed for a facility
containing multiple controlled doors, credential readers, door-position
sensors, request-to-exit devices, locking hardware, and a central
management server. The customer requires centralized credential
administration, event monitoring, time schedules, and the ability to
immediately disable a lost credential. Which architecture would BEST
satisfy these requirements?
A. A purely mechanical key system with duplicate keys stored by security
personnel
B. A standalone keypad installed independently at every door with no
central communication
C. A networked access control system with intelligent controllers
,connected to centralized management software
D. A CCTV-only system in which operators manually identify employees
before allowing entry
The centralized networked architecture allows credentials, schedules,
events, and access permissions to be administered from a common
management platform while controllers continue operating door functions
locally.
2. In a typical electronic access control installation, what is the primary
responsibility of the access control controller after receiving a
credential transaction from a reader?
A. Convert AC mains power directly into mechanical locking force
B. Store video recordings from nearby surveillance cameras
C. Evaluate the transaction against programmed authorization rules and
control the appropriate door output
D. Replace the need for a door-position sensor
The controller is the decision-making device that processes reader
information, applies authorization rules, and commands locking or
unlocking functions according to system programming.
3. A technician is installing a proximity-card reader at a secured
entrance. The reader sends credential information to the controller
, using a reader interface. Which statement BEST describes the purpose
of the reader interface?
A. It mechanically reinforces the door frame
B. It provides the electrical communication path through which credential
data and related reader signals reach the controller
C. It supplies compressed air to the locking device
D. It converts the credential into a CCTV image
The reader interface carries credential information and associated
signaling between the reader and controller, allowing the controller to
evaluate the presented credential.
4. A door is equipped with an electromagnetic lock that releases when
power is removed. During a power failure, the customer wants
occupants to be able to exit safely while maintaining appropriate
security requirements. Which characteristic of the lock is most
important to recognize during system design?
A. It is always mechanically locked regardless of power condition
B. It cannot be connected to an access control controller
C. Its locked or unlocked state depends on the presence or absence of
electrical power
D. It functions only when connected to a fire alarm speaker
, An electromagnetic lock is normally energized to remain locked, so loss of
power can release it. Its behavior must therefore be coordinated with life-
safety requirements and the facility's emergency egress design.
5. A technician measures voltage at the controller power supply and
finds that the nominal 12 VDC supply drops significantly when several
locks activate simultaneously. Which condition is the MOST likely
cause?
A. Excessive credential database capacity
B. Incorrect cardholder naming convention
C. Insufficient power-supply capacity or excessive voltage drop in the
distribution wiring
D. Excessive camera resolution
Multiple locks can create substantial current demand. An undersized
power supply or excessive resistance in the wiring can cause the system
voltage to fall when the load is energized.
6. An access control system must permit an employee to enter the
building only from 07:00 to 18:00 Monday through Friday. Which
programming feature should the technician use?
A. Door-position alarm
B. Reader tamper alarm
