A sloping ceiling is one that has a slope of more than ____ in ____.
Correct Answer
B. 1/8
Explanation
A sloping ceiling is one that has a slope of more than 1/8. This means that the angle of the slope is greater than 1/8, indicating that the ceiling is not flat but rather inclined or slanted. The other options, 1/4 and 2/1, do not meet the criteria of a sloping ceiling as they represent steeper slopes. The option "anything not flat" is too vague and does not provide a specific measurement for the slope.

A ______ is a source of electrical operating power, including the circuits and terminations connecting it to the dependent system components
Correct Answer
C. Power supply
Explanation
A power supply is a device that provides electrical operating power to a system. It includes the necessary circuits and terminations to connect it to the dependent components of the system. The power supply is responsible for converting the input power from a source, such as an electrical outlet or a battery, into the appropriate form and voltage required by the system. It ensures a steady and reliable flow of power to the system, enabling it to function properly.

Shop drawings include all the following except:
Correct Answer
A. Floor or level identification
Explanation
Shop drawings are detailed drawings created by contractors, fabricators, or manufacturers to illustrate the specific installation or construction details of a project. They typically include information such as dimensions, materials, and installation methods. The floor or level identification is not typically included in shop drawings as it is not relevant to the specific installation details. The other options mentioned, such as the location of protected premises, date of issue and revision dates, and the name of the installer or contractor, are commonly included in shop drawings to provide clarity and accountability.

Definitions may be found in Chapter _______ of NFPA 72.
Correct Answer
C. 3
Explanation
NFPA 72 is a standard for the installation, testing, and maintenance of fire alarm systems. It provides guidelines and requirements for the design and operation of these systems. The question is asking for the chapter in NFPA 72 where definitions can be found. The correct answer is 3, which suggests that Chapter 3 of NFPA 72 contains the definitions. This chapter is likely dedicated to defining the terms and concepts used throughout the standard, ensuring clarity and consistency in interpretation and application.
8.
The distance between the continuous floor of a room to the continuous ceiling of a room or space:
Correct Answer
B. Ceiling height
Explanation
Ceiling height refers to the distance between the continuous floor of a room and the continuous ceiling of that room or space. This measurement is important for various purposes, including determining the appropriate placement of smoke detectors. The higher the ceiling, the higher the smoke detector should be mounted to ensure effective detection and early warning in case of a fire. Therefore, ceiling height is the most relevant option among the given choices for this question.

A public switched telephone network utilizes managed facilities-based networks to provide the general public with the ability to establish communications channels via discrete dialing codes.
Correct Answer
A. True
Explanation
A public switched telephone network (PSTN) is a telecommunications network that uses managed facilities-based networks to provide the general public with the ability to establish communication channels. This means that the PSTN allows people to make phone calls by dialing specific codes. Therefore, the statement "A public switched telephone network utilizes managed facilities-based networks to provide the general public with the ability to establish communications channels via discrete dialing codes" is true.
10.
Which of the following is not a line-type detector?
Correct Answer
C. Duct detectors
Explanation
Duct detectors are not line-type detectors. Line-type detectors are typically used to detect smoke or heat along a linear path, such as in a beam or cable. Duct detectors, on the other hand, are specifically designed to detect smoke or heat within HVAC ductwork. They are installed within the ducts and monitor the air passing through for any signs of smoke or heat. Therefore, duct detectors do not fall under the category of line-type detectors.
