Free CRL Security Systems & Electronic Access Questions and Answers

Question 1

Which of the following is a common component of an electronic access control system?

Accepted Answer

Magnetic stripe reader

Answer

A magnetic stripe reader is a common component of an electronic access control system. These readers are used to scan cards with magnetic stripes, which contain encoded access credentials. When a valid card is swiped, the reader communicates with the access control panel to grant or deny entry, making it a fundamental part of many electronic security setups.

Question 2

What type of lock is typically used with keypads or card readers?

Accepted Answer

Electromagnetic lock

Answer

Electromagnetic locks (maglocks) are typically used with keypads or card readers in electronic access control systems. These locks consist of an electromagnet mounted on the door frame and an armature plate on the door. When power is applied, the magnet holds the door securely shut, and access is granted by momentarily cutting power via a keypad, card reader, or other electronic credential.

Question 3

Which security feature records entries and exits in an electronic access system?

Accepted Answer

Audit trail

Answer

An audit trail is a crucial security feature in electronic access systems that records entries and exits. It logs details such as who accessed a door, when they did so, and whether access was granted or denied. This data is invaluable for security monitoring, investigating incidents, and maintaining accountability within a controlled environment.

Question 4

In electronic access systems, what does 'fail-secure' mean?

Accepted Answer

Door stays locked during power failure

Answer

In electronic access systems, 'fail-secure' means that the door stays locked during a power failure. This design prioritizes security, ensuring that an unauthorized person cannot gain access if the system loses power. Conversely, 'fail-safe' systems unlock during a power failure, prioritizing safety and egress in emergencies.

Question 5

What is the primary role of a Request-to-Exit (REX) sensor?

Accepted Answer

Allow egress by detecting movement

Answer

The primary role of a Request-to-Exit (REX) sensor is to allow egress (exit) from a secured area by detecting movement. When a person approaches the door from the inside, the REX sensor detects their presence and signals the access control system to momentarily unlock the door. This enables free exit without needing a credential, while maintaining security for entry.
