CST Card Reader & Biometric Access 5

Question 1

A facility experiences frequent 'door held open' alarms. The MOST likely cause is:

Accepted Answer

Users are propping the door open or not allowing it to fully latch

Answer

'Door held open' alarms trigger when a door remains open beyond the configured time, most commonly due to users physically propping or impeding the door from closing.

Question 2

What is the function of a 'request-to-exit' (REX) device in an access control system?

Accepted Answer

It signals the panel to unlock the door for egress without using a credential

Answer

A REX device (motion sensor or push button) signals the access control panel to release the door latch for egress, allowing exit without a card swipe.

Question 3

Which biometric technology analyzes the pattern of veins beneath the skin surface for identification?

Accepted Answer

Vascular (vein) pattern recognition

Answer

Vascular recognition captures near-infrared images of subcutaneous vein patterns in the hand or finger, which are extremely difficult to spoof.

Question 4

During a fire alarm activation, most access control systems are programmed to:

Accepted Answer

Unlock all controlled egress doors (fail-safe mode) to allow evacuation

Answer

Life-safety codes require access-controlled egress doors to fail-safe (unlock) upon fire alarm activation to allow unimpeded evacuation.

Question 5

A smart card stores biometric data directly on the card rather than in a central database. This approach is called:

Accepted Answer

Match-on-card (MoC)

Answer

Match-on-card (MoC) stores and processes the biometric template on the card itself, enhancing privacy since biometric data never leaves the credential.
