ALOA Access Control Systems

Question 1

Which access control credential technology uses radio frequency to read a card or fob without physical contact?

Accepted Answer

RFID (Radio Frequency Identification)

Answer

RFID technology reads credential data wirelessly using radio frequency signals between the card/fob and the reader.

Question 2

In access control terminology, what does 'fail-safe' mean?

Accepted Answer

The lock unlocks (opens) when power is lost

Answer

A fail-safe lock is electrically unlocked, meaning it opens (fails to the safe/egress position) when power is removed.

Question 3

What does 'fail-secure' mean in an electrified locking device?

Accepted Answer

The lock remains locked (secured) when power is lost

Answer

A fail-secure lock is electrically locked, meaning it stays locked when power is removed, prioritizing security over free egress.

Question 4

Which component in an access control system reads the credential and sends data to the controller?

Accepted Answer

Reader

Answer

The reader (card reader, keypad, or biometric device) captures credential data and transmits it to the access control panel for verification.

Question 5

What is a Request-to-Exit (REX) device used for in access control?

A REX device (motion sensor or push button) detects egress and suppresses the door alarm to prevent false alarms when authorized users exit.
