- 1.
Batteries are composed of toxic material that cannot be recycled.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Batteries are not composed entirely of toxic materials that cannot be recycled. While some components of batteries, such as certain metals and chemicals, can be harmful to the environment if not properly disposed of, many parts of batteries can be recycled. In fact, recycling batteries is an important practice to prevent the release of harmful substances into the environment and to recover valuable materials for reuse. Therefore, the statement that batteries cannot be recycled is false.Rate this question:

One disadvantage of lithium ion batteries is that they
- A.
Are heavier than lead acid batteries.
- B.
Have a tendency to create a “memory” when not depleted completely.
- C.
Have a much shorter shelf life than other types of batteries.
- D.
Are more expensive than other forms of batteries.
Correct Answer
D. Are more expensive than other forms of batteries.Explanation
Lithium batteries are more expensive but have a longer life so they can actually cost less over the life of the battery.Rate this question:

Remote access of security systems via telephone apps or computer interfaces allows such features as arming and disarming as well as thermostat or lighting control.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Remote access of security systems via telephone apps or computer interfaces allows users to control various features such as arming and disarming the system, as well as controlling the thermostat or lighting. This means that users can conveniently manage their security system and adjust settings even when they are not physically present at the location. Therefore, the statement that remote access allows such features is true.Rate this question:

Older types of alarm systems used direct wire or McCulloh Loops to transmit alarms. Voltage was induced on the line that was carried from point A to point B. In most places today these are not possible any longer due to
- A.
The demise of the phone company.
- B.
Upgraded fiber optic installations.
- C.
The introduction of radio systems.
- D.
Nothing. Actually, they are still widely used across the country
Correct Answer
B. Upgraded fiber optic installations.Explanation
Fiber installations do not carry voltage, instead they transfer light impulses.Rate this question:

The larger the gauge wire used, the higher the heat produced.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The statement is incorrect. The larger the gauge wire used, the lower the heat produced. This is because larger gauge wires have a lower resistance, which means that less heat is generated when current flows through them.Rate this question:

Of the following, which is not a type of technology used for home energy management associated with alarm systems?
- A.
Zigbee
- B.
X-10
- C.
Z-Wave
- D.
GPRS
Correct Answer
D. GPRSExplanation
GPRS (General Packet Radio Service) is not a type of technology used for home energy management associated with alarm systems. GPRS is a mobile data service that allows for wireless communication over cellular networks, but it is not specifically designed for home energy management or alarm systems. Zigbee, X-10, and Z-Wave, on the other hand, are all types of wireless communication protocols commonly used in home automation and energy management systems.Rate this question:

Using energy management systems to operate equipment such as water heaters, lighting controls, and thermostats is actually not cost-effective due to the high cost of the initial investment of electronic equipment.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Using energy management systems to operate equipment such as water heaters, lighting controls, and thermostats is actually cost-effective despite the high cost of the initial investment of electronic equipment.Rate this question:

Which one of the following should always be used as the grounding electrode?
- A.
A continuous metallic underground water piping system
- B.
An iron rod driven six feet down with a resistance of 25 ohms or more
- C.
A buried plate with an area of no more than 1 square foot
- D.
An electrical outlet grounding screw
Correct Answer
A. A continuous metallic underground water piping systemExplanation
A continuous metallic underground water piping system should always be used as the grounding electrode because it provides a low-resistance path for electrical current to flow into the ground. This helps to protect against electrical faults and ensures that the electrical system remains grounded properly.Rate this question:

An advantage of a fluorescent bulb over an incandescent bulb is that it
- A.
Is easier to install.
- B.
Utilizes less wiring.
- C.
Is easier to dispose.
- D.
Is more efficient.
Correct Answer
D. Is more efficient.Explanation
A fluorescent bulb is more efficient than an incandescent bulb because it produces more light while using less energy. This is because fluorescent bulbs convert more of the electrical energy they consume into visible light, whereas incandescent bulbs waste a significant amount of energy as heat. As a result, fluorescent bulbs are able to produce the same amount of light as incandescent bulbs while consuming less electricity, making them a more energy-efficient choice.Rate this question:

Which of the following would be the best choice when running a ground wire for an alarm panel?
- A.
Always make a “service loop” at the point of connection.
- B.
Make the connection to a known ground source.
- C.
Run it to the closest cold water pipe.
- D.
The smaller the wire, the easier it is to fish into the wall.
Correct Answer
B. Make the connection to a known ground source.Explanation
When running a ground wire for an alarm panel, the best choice would be to make the connection to a known ground source. This ensures that the ground wire is properly connected to a reliable and established ground, which is essential for the safety and proper functioning of the alarm system. Making a "service loop" at the point of connection is a good practice, but it is not specifically related to the choice of ground source. Running the wire to the closest cold water pipe may not guarantee a reliable ground connection, as the pipe may not be properly grounded. The size of the wire does not affect the choice of ground source.Rate this question:

Alarm systems should not have additional features, such as energy management, integrated with them due to the increased risk of false alarms.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Integrated features have no correlation to false alarms.Rate this question:

Due to the high cost of maintaining legacy systems of transmission, the 2010 Edition of NFPA 72 eliminated the use of older technologies.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The old technologies were eliminated from the code because of the use of Other Transmission Technologies. Since these older methods fell into this category, there was no need for a specific section pertaining to them.Rate this question:

The most energy-efficient CCTV cameras are those that
- A.
Require sodium pressure lighting for visibility.
- B.
Use IR illumination.
- C.
Are considered night time or starlight cameras.
- D.
All draw the same power.
Correct Answer
C. Are considered night time or starlight cameras.Explanation
Because low-light and starlight cameras can “see in the dark,” there is no need for external lighting and therefore they are the most cost-effective in terms of usage.Rate this question:

Which of the following is not able to be integrated into a home automation system?
- A.
Lighting controls
- B.
Thermostat controls
- C.
Irrigation controls
- D.
Drapery controls
- E.
Both c. and d.
- F.
They all can be integrated.
Correct Answer
F. They all can be integrated.Explanation
The correct answer is "They all can be integrated." This means that all of the options listed (lighting controls, thermostat controls, irrigation controls, and drapery controls) are able to be integrated into a home automation system. This implies that there is no option that cannot be integrated, indicating that all of the listed options are compatible with a home automation system.Rate this question:
