Question 1

A silent alarm is more desirable than an audible alarm.

Accepted Answer

A silent alarm is more discreet and reduces the risk of alerting intruders to their detection. An audible alarm can also cause unnecessary panic and noise pollution.

Question 2

Most door and window contacts are "normally closed".

Accepted Answer

Most door and window contacts are designed to be in a closed state when the door or window is shut, signaling that the entry point is secure. When the door or window is opened, the contact is broken and an alarm is triggered. This is known as a "normally closed" configuration.

Question 3

Wiring and cabling for all access control systems must comply with Article 300 of the National Electrical Code.

Accepted Answer

Access control systems typically must comply with Article 725 of the National Electrical Code, which covers remote-control, signaling, and power-limited circuits, not Article 300, which is more general and covers wiring methods.

Question 4

What size resistor is typically used as an EOL resistor?
A) 1000 ohm
B) 4700 ohm
C) 6800 ohm
D) 10 Kohm

Accepted Answer

4700 ohm resistors are commonly used as End of Line (EOL) resistors in security systems to monitor the integrity of alarm sensor circuits.

Question 5

Immediate proximity cards must pass __________ from the reader.
A) Less than 2 mm
B) less than 1 mm
C) 10 cm
D) 30 cm

Accepted Answer

Immediate proximity cards typically need to be held within 1 mm of the reader in order to be read. Options A and C may be too broad, while option D is too far for immediate proximity cards.

Question 6

What type of battery is used for the battery backup in an access control syste?
A) Sealed battery
B) Lead-acid battery
C) Gel-type battery
D) All the above

Accepted Answer

All the options listed, sealed, lead-acid, and gel-type batteries, are types of batteries that can be used for battery backup in access control systems. These batteries are known for their reliability, durability, and maintenance-free characteristics, making them suitable for security applications.

Question 7

A good rule with power supplies is to not load them more than _____ of their capacity.
A) 50%
B) 60%
C) 70%
D) 100%

Accepted Answer

A good rule with power supplies is to not load them more than 70% of their capacity. This ensures they operate efficiently, have a buffer for occasional power spikes, and helps in prolonging their lifespan.

Question 8

Typically, access control systems only require one power supply.

Accepted Answer

Access control systems typically require multiple power supplies to power different components such as door locks, readers, and controllers.

Question 9

Diodes are used to protect against inductive kick on an electronic strike.

Accepted Answer

The answer of Diodes are used to protect against inductive...

Question 10

The primary function of an access control system is to ______.
A) Protect valuables
B) Limit access to a desired location
C) Secure the perimeter
D) All the above

Accepted Answer

The primary function of an access control system is to limit access to a desired location. While it can also help protect valuables and secure the perimeter, its main purpose is to control who is allowed entry into a specific area.

Question 11

The most important function of a keypad is to ________.
A) Act as an interface between the sensors and the electronic strikes.
B) Provide audible alerts for the occupants.
C) Sense motion in the general area of the keypad.
D) Provide the ability to arm and disarm the alarm.

Accepted Answer

The most important function of a keypad is to provide the ability to arm and disarm the alarm. This allows the user to control the security system and protect their property. While keypads can have other functions such as providing audible alerts, sensing motion, or serving as an interface between sensors and electronic strikes, these are not their primary purpose.

Question 12

What type of card reader does not require physical contact to occur?
A) Wiegand
B) Magstripe
C) ATM
D) All the above

Accepted Answer

Wiegand card readers use radio frequency technology to communicate with the card, allowing for contactless access. Magstripe and ATM readers require physical contact with the card.

Question 13

You will never connect a magnetic lock directly to AC of any voltage.

Accepted Answer

Magnetic locks must be connected to a low voltage DC power source through a power supply in order to function properly and safely. Connecting them directly to AC voltage can cause damage to the lock and pose a safety hazard.

Question 14

The installation of class two power sources must comply with Article 725 of the National Electrical Code.

Accepted Answer

Article 725 of the National Electrical Code provides requirements for the installation of Class 2 and Class 3 power sources, and Class 2 power sources are specifically mentioned in this article.

Question 15

An electric strike will typically operate from_________.
A) 3 or 6 V
B) 6 V
C) 12 or 24 V
D) 48 V

Accepted Answer

An electric strike will typically operate from 12 or 24 V. While it's possible for some electric strikes to operate from other voltages, such as 3 or 6 V, 12 or 24 V is the most common range for commercial and residential installations. 48 V is generally too high for electric strikes and is more commonly used in industrial applications.

Question 16

Most door and window contacts are wired as _________.
A) Normally open
B) Normally closed
C) Always open
D) Always closed

Accepted Answer

Most door and window contacts are wired as normally open which means they are in an open state when the door or window is closed. This allows the circuit to be completed when the door or window is opened, triggering the alarm system.

Question 17

What cable is preferred when wiring a security system?
A) Copper clad aluminum
B) 18-22 AWG, twisted 2-wire, stranded
C) Not smaller than 14 AWG copper
D) Any CAT 5 cable

Accepted Answer

Not smaller than 14 AWG copper is preferred because it can handle higher voltage and current than smaller wires, providing better signal quality and less resistance.

Question 18

Most access control systems are connected to the buildings network through a CAT 5 cable.

Accepted Answer

Most access control systems are connected to the buildings network through a CAT 5 cable.

Question 19

Maglocks are always fail-secure.

Accepted Answer

Maglocks can be both fail-secure or fail-safe, depending on their configuration. Fail-secure means that the lock will remain locked when power is lost, while fail-safe means that the lock will be released when power is lost.

Question 20

The type of sensing device to use in a access control systems typically depends on the layout of the building and the detail in which you need protection.

Accepted Answer

The type of sensing device used in an access control system depends on factors such as the layout of the building and the level of protection needed. There is no one-size-fits-all solution.
