4. An access system's “site code” is:
   1. an identification number that's included in each access credential
   2. the access controller panel’s MAC address

   4. the installer’s account number


5. Standard proximity credential readers have a two-foot “read” distance.
   1. True
   2. False


6. Typically, biometric access control devices cannot read:
   1. palm prints
   2. fingerprints
   3. human irises
   4. human pulse rates


7. Electronic REX devices are typically connected directly to credential readers.
   1. True
   2. False


8. A door release that goes “open” when power fails is considered:
   1. fail-secure
   2. fail-safe


9. The most important issue when planning an access control system is:
   1. the number of credentials to be issued.
   2. the number of doors to be secured.
   3. life safety and AHJ approval.
   4. how fast credentials can be read and access allowed.


10. Door releases, such as strikes and magnetic locks, typically are powered by:
    1. self-contained batteries.
    2. separate power supplies.
    3. AC
    4. power from the access controller panel.


11. The average number of credentials in a typical access control application is:
    1. 50
    2. 100
    3. 200
    4. 500


12. Access controller panels can communicate with the host computer via:
    1. Ethernet
    2. Internet
    3. RS-485
    4. telephone modem


13. Keypad access control input devices provide high-speed, high-volume entry functions.
    1. True
    2. False


14. Select the incorrect answer. Door position switches:
    1. also can be connected to intrusion alarm systems.
    2. provide door close/open status to the access control system.
    3. can be contained in hinges.
    4. can be surface mount or concealed.


15. Which type of system typically provides real-time monitoring and reporting of access control events?
    1. Mid-sized systems.
    2. Enterprise-level systems.


16. Electronic REXs should be protected with bridge rectifier circuits when connected to a magnetic lock or door strike.
    1. True
    2. False


17. Proximity readers can be used as direct replacements for magnetic stripe readers, while retaining the existing host system.
    1. True
    2. False


18. The current draw of a typical door strike is:
    1. 1.5 amps @ 24 VDC
    2. 2 amps @ 24 VDC
    3. 300 milliamps @ 24 VDC
    4. 150 milliamps @ 24 VDC


19. When two or more people pass through an access door when only one credential is presented, this is called:
    1. cheating the system
    2. papoosing
    3. tailgating
    4. a “spare tire”


20. Secure funneling is when two or more doors are logically connected so that one door must be closed before another door can be opened.
    1. True
    2. False

Why Does Door Strike Release from the Inside?

20 answers

1. c
2. d – In most cases six-conductor OAS (over all shielded) is installed, as cable manufacturers don’t regularly manufacture equivalent five-conductor. It’s important to properly connect the reader cables shielding to ground.
3. d – Card populations can be purchased with different bit formats.
4. a – The site code (also called a facility code) is like the prefix of a telephone number and is included in the data string of each credential issued for a particular system.
5. False
6. d – Human pulse rate. Biometric readers can be purchased that can read all of the other listed inputs.
7. False – Credential readers are usually connected to an access controller panel.
8. b – Fail-safe.
9. c – Life safety and AHJ approval.
10. b – Separate power supplies.
11. c – 200.
12. a, b, c, and d – The communications capability of particular access controller panels can be one or multiple methods.
13. False – Keypads are slower than cards or “hard” credentials, as the user must remember his or her number and punch it in.
14. a – Door position switches should not be connected to both the access control system and the intrusion alarm system, unless the switch selected is DPDT (double pole, double throw) which provides electrically separate connections to the respective systems.
15. b
16. True – Some magnetic locks and strikes have electric spike protection built in (this is sometimes called diode protected). If the door release isn’t internally protected, a bridge rectifier circuit should be connected.
17. True
18. d – Door-release devices operating at 12 VDC typically have a higher current requirement than those that operate at 24 VDC do.
19. c.
20. False – The correct term is “mantrap.”
