The most popular access control credential technology used today is:
- Magnetic stripe
- Wiegand swipe readers
- Bar code
Wiegand protocol readers are wired to access controller panels using:
- Cat 5e UTP
- Cat 3 UTP
- 18-gauge five-conductor with an overall shield
Wiegand protocols can be transmitted as:
- 37 bits
- 32 bits
- 26 bits
- all of the above
An access system's â€œsite codeâ€ is:
- an identification number that's included in each access credential
- the access controller panelâ€™s MAC address
- the clientâ€™s access software activation code
- the installerâ€™s account number
Standard proximity credential readers have a two-foot â€œreadâ€ distance.
Typically, biometric access control devices cannot read:
- palm prints
- human irises
- human pulse rates
Electronic REX devices are typically connected directly to credential readers.
A door release that goes â€œopenâ€ when power fails is considered:
The most important issue when planning an access control system is:
- the number of credentials to be issued.
- the number of doors to be secured.
- life safety and AHJ approval.
- how fast credentials can be read and access allowed.
Door releases, such as strikes and magnetic locks, typically are powered by:
- self-contained batteries.
- separate power supplies.
- power from the access controller panel.
The average number of credentials in a typical access control application is:
Access controller panels can communicate with the host computer via:
- telephone modem
Keypad access control input devices provide high-speed, high-volume entry functions.
Select the incorrect answer. Door position switches:
- also can be connected to intrusion alarm systems.
- provide door close/open status to the access control system.
- can be contained in hinges.
- can be surface mount or concealed.
Which type of system typically provides real-time monitoring and reporting of access control events?
- Mid-sized systems.
- Enterprise-level systems.
Electronic REXs should be protected with bridge rectifier circuits when connected to a magnetic lock or door strike.
Proximity readers can be used as direct replacements for magnetic stripe readers, while retaining the existing host system.
The current draw of a typical door strike is:
- 1.5 amps @ 24 VDC
- 2 amps @ 24 VDC
- 300 milliamps @ 24 VDC
- 150 milliamps @ 24 VDC
When two or more people pass through an access door when only one credential is presented, this is called:
- cheating the system
- a â€œspare tireâ€
Secure funneling is when two or more doors are logically connected so that one door must be closed before another door can be opened.

Help Complete this Door InstallationThe door illustrated at this facility is used for both entering and leaving the building. The door has a push bar to exit. What devices are missing from this installation?
Why Does Door Strike Release from the Inside?When some authorized users walk past this door from the inside, they hear the door strike release. What's causing this?
- d â€“ In most cases six-conductor OAS (over all shielded) is installed, as cable manufacturers donâ€™t regularly manufacture equivalent five-conductor. Itâ€™s important to properly connect the reader cables shielding to ground.
- d â€“ Card populations can be purchased with different bit formats.
- a â€“ 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.
- d â€“ Human pulse rate. Biometric readers can be purchased that can read all of the other listed inputs.
- False â€“ Credential readers are usually connected to an access controller panel.
- b â€“ Fail-safe.
- c â€“ Life safety and AHJ approval.
- b â€“ Separate power supplies.
- c â€“ 200.
- a, b, c, and d â€“ The communications capability of particular access controller panels can be one or multiple methods.
- False â€“ Keypads are slower than cards or â€œhardâ€ credentials, as the user must remember his or her number and punch it in.
- a â€“ 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.
- True â€“ Some magnetic locks and strikes have electric spike protection built in (this is sometimes called diode protected). If the door release isnâ€™t internally protected, a bridge rectifier circuit should be connected.
- d â€“ Door-release devices operating at 12 VDC typically have a higher current requirement than those that operate at 24 VDC do.
- False â€“ The correct term is â€œmantrap.â€
