Questions and Answers
- 1.
Waterflow alarm devices shall be installed so that any flow of water from ______ sprinkler head(s) of ______ size(s) installed on the system will result in an audible alarm.
- A.
2 / largest
- B.
2 / any
- C.
1 / smallest
- D.
All / all
Correct Answer
C. 1 / smallestExplanation
Waterflow alarm devices are installed to detect any flow of water from sprinkler heads. The devices should be able to detect even the smallest flow of water from the sprinkler heads. This ensures that any potential water leakage or fire incident can be promptly detected and an audible alarm can be raised to alert the occupants or authorities. Therefore, the correct answer is 1 / smallest.Rate this question:

An audible alarm shall sound on the premises within ______ after water flows.
- A.
30 seconds
- B.
90 seconds
- C.
3 minutues
- D.
5 minutes
Correct Answer
B. 90 secondsExplanation
An audible alarm is required to sound on the premises within 90 seconds after water flows. This means that once water starts flowing, the alarm should be activated within a minute and a half. This time frame is important as it allows for quick detection and response to any water-related issues or emergencies, ensuring that appropriate actions can be taken promptly to mitigate any potential damages or risks.Rate this question:

What does the alarm apparatus for a wet pipe system consist of?
- A.
Listed alarm check valve with the necessary attachments required to give an alarm
- B.
Clapper valve installed in the direction of water flow with weatherproof connectors
- C.
Outdoor water motor gong
- D.
Pressure gauge and check valve
Correct Answer
A. Listed alarm check valve with the necessary attachments required to give an alarmExplanation
The alarm apparatus for a wet pipe system consists of a listed alarm check valve with the necessary attachments required to give an alarm. This valve is designed to detect any changes in water pressure within the system and activate an alarm when necessary. The necessary attachments may include pressure gauges and check valves to ensure the proper functioning of the system.Rate this question:

The alarm apparatus for deluge and pre-action systems shall consist of alarms actuated ______ the detection system and the flow of water.
- A.
Immediately by
- B.
Within 5 minutes of
- C.
Independently of
- D.
All of the above
Correct Answer
C. Independently ofExplanation
The correct answer is "independently of". This means that the alarm apparatus for deluge and pre-action systems should be activated regardless of whether it is triggered by the detection system or the flow of water. In other words, the alarms should be able to sound even if only one of these factors is present.Rate this question:

Electrically operated alarm attachments forming part of an auxiliary, central station, local protective, proprietary or remote station signaling system shall be installed in accordance with
- A.
NFPA 13
- B.
NFPA 10
- C.
NFPA 70
- D.
NFPA 72
Correct Answer
D. NFPA 72Explanation
Electrically operated alarm attachments forming part of an auxiliary, central station, local protective, proprietary or remote station signaling system shall be installed in accordance with NFPA 72.Rate this question:
-
- 6.
Sprinkler waterflow alarm systems that are not part of a required protective signaling system shall not be required to be supervised and shall be installed in accordance with ______ .
- A.
NFPA 13
- B.
NFPA 10
- C.
NFPA 70
- D.
NFPA 72
Correct Answer
C. NFPA 70Explanation
NFPA 70, also known as the National Electrical Code (NEC), provides guidelines for electrical installations. It covers the installation of electrical equipment and wiring, including fire alarm systems. In this case, the sprinkler waterflow alarm systems are not required to be supervised if they are not part of a required protective signaling system. Therefore, they can be installed in accordance with NFPA 70, which provides the necessary electrical installation guidelines.Rate this question:
-
- 7.
Outdoor electric alarm devices shall be ______.
- A.
Prohibited
- B.
Listed for outdoor use
- C.
Weather resistant
- D.
Of the low voltage type only
Correct Answer
B. Listed for outdoor useExplanation
Outdoor electric alarm devices need to be able to withstand the elements and function properly in outdoor conditions. Therefore, they should be "listed for outdoor use", meaning they have been tested and certified to meet specific safety and performance standards for outdoor environments. This ensures that the alarm devices are designed and built to withstand exposure to moisture, temperature changes, and other outdoor conditions, making them suitable for outdoor installation and use.Rate this question:

A wet pipe system shall not be permitted to supply an auxiliary dry pipe system.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The statement is false because a wet pipe system can supply an auxiliary dry pipe system. In some cases, a wet pipe system may be connected to a dry pipe system to provide additional fire protection. This is commonly done in areas where freezing temperatures are a concern, as the dry pipe system prevents water from freezing in the pipes. Therefore, it is incorrect to say that a wet pipe system cannot supply an auxiliary dry pipe system.Rate this question:

The color classification for a sprinkler head of the “extra high” temperature range shall be ______
- A.
Red
- B.
Yellow
- C.
Purple
- D.
Black
Correct Answer
C. PurpleExplanation
The color classification for a sprinkler head of the "extra high" temperature range is purple.Rate this question:

Sprinkler heads may be painted provided they use specially designed lead-based paint.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Sprinkler heads should not be painted, even if they use specially designed lead-based paint. This is because painting the sprinkler heads can interfere with their functionality and cause them to malfunction in the event of a fire. It is important to keep the sprinkler heads clean and free from any obstruction to ensure their proper operation. Therefore, the statement that sprinkler heads may be painted is false.Rate this question:

If pressure or waterflow switches are used to shut down elevator power, the use of devices with time-delay capability shall be permitted.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The statement is false because according to the given information, the use of devices with time-delay capability shall be permitted when pressure or waterflow switches are used to shut down elevator power.Rate this question:
-

When a heat detector is used to power elevator shutdown, it is recommended that there can be a delay, and that delay should be approximately the time it takes for the elevator car to travel from the top of the hoistway to the lowest recall level.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
It is recommended to have a delay in the power shutdown of an elevator when a heat detector is used. This delay should be approximately the time it takes for the elevator car to travel from the top of the hoistway to the lowest recall level. This delay allows the elevator to safely reach the recall level before shutting down, ensuring the safety of the passengers inside.Rate this question:

- A.
30
- B.
60
- C.
90
- D.
210
Correct Answer
C. 90Explanation
The correct answer is 90. According to the question, activation of the initiating device should occur within a certain number of seconds after waterflow at the alarm-initiating device. Out of the given options, 90 is the only value that satisfies this condition.Rate this question:

The required response criterion in question 14, between initial flow of water and the electronic signal to the fire alarm control panel ______ polling delays introduced by the fire alarm control unit.
- A.
Does include
- B.
Does not include
- C.
Limits
- D.
Prohibits
Correct Answer
B. Does not includeExplanation
The question is asking about the response criterion between the initial flow of water and the electronic signal to the fire alarm control panel. The correct answer, "does not include," suggests that there are no polling delays introduced by the fire alarm control unit in this response criterion. In other words, the time it takes for the electronic signal to reach the fire alarm control panel is not affected by any delays caused by the fire alarm control unit.Rate this question:
