5-Minute Tech Quiz Answers

  1. b - Plenum-rated cable should be used whenever wire is run above a drop ceiling when the area above the ceiling is used as an air return for the HVAC system. If there is no drop ceiling or if there is a ducted air return, plenum-rated wire is generally not required.

  2. b Although Cat 5e cable could be used, it is more expensive than standard 22/4 cable.

  3. a

  4. c

  5. b Many inter-panel communication cables do not require shielded cable.

  6. d

  7. b

  8. b

  9. b

  10. b Fail-safe locks require power to lock. Fail-secure locks require power to unlock.

  11. d

  12. b Surge current is the amount of current a lock draws when it is initially energized. It typically is higher than the normal current draw of the lock.

  13. a

  14. b Although easy egress hardware allows people to exit without using a REX device, it is common to install a REX motion so that door status can be supervised. Typically, the REX motion is programmed to shunt the status switch but not release the lock.

  15. b Because anti-passback requires users to swipe before they can exit or before they can enter, using a request-to-exit device defeats the purpose, although one may be used to allow a receptionist to grant a visitor entry or exit.
