Introduction
The Connecticut Access Control Systems Contractor examination assesses the knowledge, skills, and
judgment required to design, install, service, and maintain electronic access control systems in
compliance with state regulations and industry standards. The exam evaluates foundational theory,
applied technical knowledge, regulatory compliance, ethical decision-making, and real-world problem-
solving. Questions are presented in multiple-choice and scenario-based formats, emphasizing practical
application and professional judgment. Candidates must demonstrate competency across electrical
principles, credential technologies, locking hardware, network integration, cybersecurity, codes, safety,
and project management. This assessment prepares candidates for the responsibilities of a licensed
access control systems contractor operating within the State of Connecticut.
SECTION ONE – QUESTIONS 1–100
Question 1
Which of the following is the primary purpose of an access control system?
A. To monitor employee productivity
B. To regulate and restrict entry into secured areas
,C. To provide video surveillance coverage
D. To automate lighting in a facility
🟢 B. To regulate and restrict entry into secured areas
🔴 Explanation: The fundamental purpose of an access control system is to control and restrict who
may enter specific areas at specific times, thereby protecting people, property, and information. While
video surveillance and lighting may complement access control, they are not its primary function.
Question 2
A fail-safe lock is designed to do which of the following during a power loss?
A. Remain locked
B. Unlock automatically
C. Require manual key override
D. Trigger an alarm
🟢 B. Unlock automatically
🔴 Explanation: A fail-safe lock releases (unlocks) when power is removed, allowing free egress. This is
typically used on egress doors to ensure life safety during emergencies such as fire or power failure.
Question 3
Which code provision most directly governs the requirement for free egress from a secured door?
A. NFPA 70
B. NFPA 101
C. NFPA 72
D. NFPA 110
🟢 B. NFPA 101
🔴 Explanation: NFPA 101, the Life Safety Code, establishes requirements for means of egress,
including that doors must allow free egress without special knowledge or effort. This directly affects
access control hardware selection and installation.
Question 4
An access control system that uses a card and a fingerprint simultaneously is an example of what?
A. Single-factor authentication
B. Two-factor authentication
,C. Three-factor authentication
D. Biometric override
🟢 B. Two-factor authentication
🔴 Explanation: Two-factor authentication requires two different types of credentials: something you
have (the card) and something you are (the fingerprint). Combining two credentials from different
categories increases security.
Question 5
What is the typical voltage output of a standard proximity card reader?
A. 5 VDC
B. 12 VDC
C. 24 VDC
D. 120 VAC
🟢 B. 12 VDC
🔴 Explanation: Most proximity card readers operate on 12 VDC nominal power, though some support
5 VDC or 24 VDC. 12 VDC is the industry standard for the majority of legacy and current reader
models.
Question 6
Which of the following best describes the function of a request-to-exit (REX) device?
A. It prevents exit during an alarm
B. It signals the access control system to unlock a door for egress
C. It records the identity of the person exiting
D. It overrides the fire alarm system
🟢 B. It signals the access control system to unlock a door for egress
🔴 Explanation: A REX device, such as a passive infrared sensor or push button, signals the access
control panel to release the lock, allowing free egress without requiring a credential. It is a critical life
safety component.
Question 7
A Wiegand interface typically consists of how many data wires?
, A. One
B. Two
C. Three
D. Four
🟢 B. Two
🔴 Explanation: The Wiegand protocol uses two data lines, DATA0 and DATA1, to transmit card data
from the reader to the controller. A separate ground and power connection are also required, but the
data transmission uses two wires.
Question 8
What is the primary safety concern when installing an electromagnetic lock on a perimeter door?
A. The lock may be too heavy for the frame
B. The lock may prevent free egress if not properly interfaced with the fire alarm
C. The lock may interfere with radio communications
D. The lock may consume excessive power
🟢 B. The lock may prevent free egress if not properly interfaced with the fire alarm
🔴 Explanation: Electromagnetic locks are fail-safe, but they must be properly interfaced with the fire
alarm system and equipped with a request-to-exit device or other release mechanism to ensure free
egress during emergencies, as required by NFPA 101.
Question 9
In a card access system, what does the term "format" refer to?
A. The physical size of the card
B. The arrangement and encoding of data on the credential
C. The color of the card
D. The material used to manufacture the card
🟢 B. The arrangement and encoding of data on the credential
🔴 Explanation: Card format defines how data is structured and encoded on the credential, including
facility code, card number, and parity bits. The format must match between the credential and the
reader for successful communication.
Question 10
Which of the following is a characteristic of a fail-secure lock?
