1.
_____________ is the maximum number of water flow switches permitted to be connected to a single ___________initiating device circuit.
Correct Answer
E. Five, conventional
Explanation
The correct answer is "Five, conventional". This means that the maximum number of water flow switches allowed to be connected to a single conventional initiating device circuit is five.
2.
A fire alarm control panel must be mounted at a location closest to the door where the firefighters will enter. This location is usually identified when submitting plans for approval by the authority having jurisdiction (AHJ).
Correct Answer
B. False
Explanation
The statement is false because a fire alarm control panel should be mounted at a location that is easily accessible to the building occupants, not just the firefighters. The location is typically determined based on factors such as visibility, accessibility, and proximity to exits. The AHJ may provide guidelines or requirements for the placement of the control panel, but it is not necessarily always closest to the door where firefighters will enter.
3.
Duct detectors that were installed by the HVAC company are not compatible with an addressable fire alarm control panel and must be replaced.
Correct Answer
B. False
Explanation
The statement implies that duct detectors installed by the HVAC company are not compatible with an addressable fire alarm control panel and must be replaced. However, the correct answer is false, indicating that the statement is incorrect. Therefore, it suggests that duct detectors installed by the HVAC company are compatible with an addressable fire alarm control panel and do not need to be replaced.
4.
When mounting smoke detectors on a wall, the sensing device has to be between four and 12 inches down from the ceiling.
Correct Answer
A. True
Explanation
The statement is false because when mounting smoke detectors on a wall, the sensing device should be placed at least 4 inches down from the ceiling.
5.
NFPA 70 is the National Fire Alarm Code.
Correct Answer
B. False
Explanation
The correct answer is false because NFPA 70 is actually the National Electrical Code, not the National Fire Alarm Code.
6.
What is the maximum number of supervisory devices permitted to be connected to a single initiating device circuit?
Correct Answer
B. 20
Explanation
The maximum number of supervisory devices permitted to be connected to a single initiating device circuit is 20. This means that the initiating device circuit can support up to 20 supervisory devices, which could include devices such as smoke detectors or heat detectors.
7.
In new one- and two-family dwellings smoke detectors are required to be installed _______________.
Correct Answer
D. All of the above
Explanation
In new one- and two-family dwellings, smoke detectors are required to be installed in all sleeping rooms, outside of each separate sleeping area, and on each level of the dwelling. This means that smoke detectors should be present in every sleeping room, as well as in the common areas outside of the sleeping areas, and on every floor of the house. Therefore, the correct answer is "All of the above."
8.
Smoke detectors are marked with a color code indicating their temperature classification.
Correct Answer
B. False
Explanation
Smoke detectors are not marked with a color code indicating their temperature classification. The color code is typically used for electrical wiring and cables, where different colors represent different temperature ratings. Smoke detectors, on the other hand, are usually marked with a label or symbol indicating their sensitivity to smoke and not their temperature classification.
9.
Comparing addressable and conventional systems, which of the following statements is true?
Correct Answer
C. There are fewer connections for field wiring in an addressable panel than in a conventional panel.
Explanation
An addressable panel requires fewer connections for field wiring compared to a conventional panel. This means that the devices connected to an addressable panel can be wired more efficiently, resulting in a simpler and less complex installation process. In contrast, a conventional panel requires more connections for field wiring, which can be time-consuming and may increase the chances of wiring errors. Therefore, the statement "There are fewer connections for field wiring in an addressable panel than in a conventional panel" is true.
10.
Initiating devices do not necessarily have to be installed independently of the circuit conductors.
Correct Answer
B. False
Explanation
Initiating devices, such as switches or sensors, are typically installed as part of the circuit conductors. They are connected within the circuit to detect changes or initiate actions. Therefore, the statement that initiating devices do not necessarily have to be installed independently of the circuit conductors is false.
11.
Any standard smoke detector is permitted to be installed in a return air plenum.
Correct Answer
B. False
Explanation
Standard smoke detectors are not permitted to be installed in a return air plenum. The return air plenum is the space where air is collected and returned to the HVAC system. Installing a smoke detector in this area can lead to false alarms or ineffective smoke detection due to the airflow and potential contaminants present in the plenum. Therefore, it is not allowed to install a standard smoke detector in a return air plenum.
12.
Which of the following is an example of a smoke detector?
Correct Answer
D. Any of the above
Explanation
The correct answer is "Any of the above" because all of the options listed (Multi-criteria, Ionization, and Photoelectric) are examples of smoke detectors. A smoke detector is a device that senses smoke in the air and emits a loud alarm to alert people of potential fire hazards. Each type of smoke detector mentioned in the options uses different technologies to detect smoke particles, but they all serve the same purpose of fire safety.
13.
Which of the following devices must be tested for functionality on an annual basis?
Correct Answer
E. All of the above
Explanation
All of the devices listed (smoke detectors, control panels, heat detectors, and pull stations) must be tested for functionality on an annual basis. This is important to ensure that they are in proper working condition and will effectively detect and respond to any fire or emergency situations. Regular testing helps to identify any faults or malfunctions in these devices and allows for timely repairs or replacements, ensuring the safety and security of the premises.
14.
Fire alarm control panels must be painted red for ease of identification as a fire alarm device.
Correct Answer
B. False
Explanation
The statement is false because fire alarm control panels do not necessarily have to be painted red for ease of identification as a fire alarm device. While red may be a common color used for fire alarm control panels, it is not a requirement. Fire alarm control panels can be painted in different colors depending on the manufacturer's design or the specific requirements of the building where they are installed. The color of the control panel does not affect its functionality or ability to be identified as a fire alarm device.
15.
When the height of a ceiling is 15-25 feet, which of the following spacing reduction factors must be used to properly locate smoke detectors?
Correct Answer
D. No reduction for smoke detectors
Explanation
When the height of a ceiling is 15-25 feet, there is no need to use spacing reduction factors for smoke detectors. This means that the detectors should be placed at the standard spacing distance without any reduction.
