Are Alarm Systems Energy Efficient?

2.

One disadvantage of lithium ion batteries is that they

Are heavier than lead acid batteries.
Have a tendency to create a “memory” when not depleted completely.
Have a much shorter shelf life than other types of batteries.
Are more expensive than other forms of batteries.

Correct Answer

A. 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.

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.

True
False

Correct Answer

A. True

Explanation

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.

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

The demise of the phone company.
Upgraded fiber optic installations.
The introduction of radio systems.
Nothing. Actually, they are still widely used across the country

Correct Answer

A. Upgraded fiber optic installations.

Explanation

Fiber installations do not carry voltage, instead they transfer light impulses.

The larger the gauge wire used, the higher the heat produced.

True
False

Correct Answer

A. False

Explanation

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.

Of the following, which is not a type of technology used for home energy management associated with alarm systems?

Zigbee
X-10
Z-Wave
GPRS

Correct Answer

A. GPRS

Explanation

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.

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.

True
False

Correct Answer

A. False

Explanation

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.

Which one of the following should always be used as the grounding electrode?

A continuous metallic underground water piping system
An iron rod driven six feet down with a resistance of 25 ohms or more
A buried plate with an area of no more than 1 square foot
An electrical outlet grounding screw

Correct Answer

A. A continuous metallic underground water piping system

Explanation

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.

An advantage of a fluorescent bulb over an incandescent bulb is that it

Is easier to install.
Utilizes less wiring.
Is easier to dispose.
Is more efficient.

Correct Answer

A. 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.

Which of the following would be the best choice when running a ground wire for an alarm panel?

Always make a “service loop” at the point of connection.
Make the connection to a known ground source.
Run it to the closest cold water pipe.
The smaller the wire, the easier it is to fish into the wall.

Correct Answer

A. 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.

Due to the high cost of maintaining legacy systems of transmission, the 2010 Edition of NFPA 72 eliminated the use of older technologies.

True
False

Correct Answer

A. False

Explanation

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.

The most energy-efficient CCTV cameras are those that

Require sodium pressure lighting for visibility.
Use IR illumination.
Are considered night time or starlight cameras.
All draw the same power.

Correct Answer

A. 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.

Which of the following is not able to be integrated into a home automation system?

Lighting controls
Thermostat controls
Irrigation controls
Drapery controls
Both c. and d.
They all can be integrated.

Correct Answer

A. 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.
