Question 2

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

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

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?
