ALOA Access Control Systems 2 — Questions and Answers
Question 1: Which type of electric strike allows the door latch to be held in the strike while the door is in the closed position and releases when energized?
- Fail-secure electric strike (Correct answer)
- Fail-safe electric strike
- Magnetic lock
- Electric bolt
Correct answer: Fail-secure electric strike
A fail-secure electric strike holds the latch captive when de-energized (locked) and releases it when power is applied (unlocked).
Question 2: What is the primary advantage of a magnetic lock (maglock) over an electric strike?
- No moving parts means longer service life and less mechanical wear (Correct answer)
- It works without electricity
- It can be installed on outswing doors only
- It is cheaper to install
Correct answer: No moving parts means longer service life and less mechanical wear
Magnetic locks have no moving parts, making them extremely durable with minimal mechanical wear compared to electric strikes with moving keeper components.
Question 3: Which access control door hardware provides motorized deadbolt locking from the access control system?
- Electric deadbolt (electric bolt) (Correct answer)
- Electric strike
- Electrified knob
- Magnetic lock
Correct answer: Electric deadbolt (electric bolt)
An electric deadbolt (or electric bolt) is a motorized or solenoid-driven bolt that extends and retracts under access control system command.
Question 4: What does 'tailgating' (or 'piggybacking') mean in physical access control security?
- An unauthorized person following an authorized person through a controlled door without presenting credentials (Correct answer)
- Cloning an access card
- Bypassing a card reader electronically
- Forcing a door open
Correct answer: An unauthorized person following an authorized person through a controlled door without presenting credentials
Tailgating occurs when an unauthorized person follows closely behind an authorized user through a secured door before it closes, gaining entry without credentials.
Question 5: Which standard defines the mechanical dimensions for cylindrical lock preps used with electrified cylindrical locks?
- ANSI/BHMA A156.2 (Correct answer)
- UL 294
- NFPA 80
- ADA 4.13
Correct answer: ANSI/BHMA A156.2
ANSI/BHMA A156.2 covers bored and preassembled locks and latches, including the mechanical prep dimensions for cylindrical lock installation.
Question 6: A biometric access control system identifies users by which method?
- Unique physical or behavioral characteristics such as fingerprints, iris patterns, or facial recognition (Correct answer)
- PIN codes entered on a keypad
- Proximity cards containing stored IDs
- Wiegand wire signals
Correct answer: Unique physical or behavioral characteristics such as fingerprints, iris patterns, or facial recognition
Biometric systems authenticate users by measuring and comparing unique physiological or behavioral traits against a stored template.
