CPL Commercial Security Solutions 2 — Questions and Answers
Question 1: Which door closer rating is typically required for fire-rated commercial exit doors?
- ANSI Grade 1 (Correct answer)
- ANSI Grade 2
- ANSI Grade 3
- UL Grade 4
Correct answer: ANSI Grade 1
ANSI Grade 1 is required for fire-rated commercial doors because it meets the highest durability and performance standards.
Question 2: A commercial facility wants to restrict access to a server room while maintaining an audit trail. Which solution best meets both requirements?
- Mechanical push-button lock
- Card access control with logging (Correct answer)
- Padlock with key log sheet
- Combination padlock
Correct answer: Card access control with logging
Card access control systems automatically log every entry and exit event, providing both restriction and a verifiable audit trail.
Question 3: What is the primary purpose of a 'delayed egress' locking device in commercial settings?
- To prevent all unauthorized entry
- To slow exit and deter shoplifting while allowing emergency egress (Correct answer)
- To lock doors permanently during business hours
- To replace panic hardware on fire doors
Correct answer: To slow exit and deter shoplifting while allowing emergency egress
Delayed egress devices introduce a timed delay (typically 15–30 seconds) to deter theft while still allowing emergency exit.
Question 4: When installing a mortise lock in a commercial aluminum storefront door, the locksmith must first consider:
- The door's color finish
- The door stile width and thickness (Correct answer)
- The type of door closer used
- The flooring material
Correct answer: The door stile width and thickness
Aluminum storefront door stiles have specific width and thickness dimensions that determine which mortise lock body will fit.
Question 5: A high-security commercial padlock that resists cutting attacks typically features:
- Brass shackle and zinc body
- Hardened steel shackle and boron-carbide reinforcement (Correct answer)
- Aluminum shackle and polycarbonate body
- Stainless shackle and plastic housing
Correct answer: Hardened steel shackle and boron-carbide reinforcement
Hardened steel shackles with boron-carbide inserts provide maximum resistance to bolt cutters and angle grinders.
Question 6: Which of the following best describes a 'fail-secure' electric strike?
- Unlocks when power is removed
- Remains locked when power is removed (Correct answer)
- Locks automatically at closing time
- Requires a key to operate during a power failure
Correct answer: Remains locked when power is removed
A fail-secure electric strike stays locked when power is lost, maintaining security but requiring manual override for emergency egress.

- One
- Two
- Three (Correct answer)
- Four
