Questions and Answers
  • 1. 

    Protected Premises Fire Alarm System is

    • A.

      Most basic

    • B.

      Designed to be initiated manually

    • C.

      Both a & b

    • D.

      Used at banks only

    Correct Answer
    C. Both a & b
    Explanation
    A Protected Premises Fire Alarm System is the most basic type of fire alarm system. It is designed to be initiated manually, meaning that it can be activated by a person in case of a fire emergency. Therefore, the correct answer is "Both a & b" as it encompasses both the basic nature of the system and its manual initiation feature.

         Automatic Alarm Systems

    • A.

      Signals through dedicated wire pairs, leased telephone lines, fiber-optic cable, or wireless communications link

    • B.

      Have a high degree of false alarms compared to other systems

    • C.

      Can only be manually activated

    • D.

      Both b & c

    Correct Answer
    A. Signals through dedicated wire pairs, leased telephone lines, fiber-optic cable, or wireless communications link
    Explanation
    Automatic alarm systems can transmit signals through dedicated wire pairs, leased telephone lines, fiber-optic cable, or wireless communications link. These systems are not limited to manual activation only, as they can be activated automatically based on certain triggers or events. However, they are known to have a high degree of false alarms compared to other systems.

          Basic types of automatic alarm-initiating devices include

    • A.

      Heat detectors

    • B.

      Rate-of-rise heat detectors

    • C.

      Smoke detectors

    • D.

      All of the above

    Correct Answer
    D. All of the above
    Explanation
    The correct answer is "All of the above" because all three types of automatic alarm-initiating devices mentioned (heat detectors, rate-of-rise heat detectors, and smoke detectors) are basic types of alarm-initiating devices. Heat detectors are designed to detect high temperatures, rate-of-rise heat detectors detect a rapid increase in temperature, and smoke detectors detect the presence of smoke. Therefore, all three types of devices can initiate an alarm in different scenarios.

    Two basic types of smoke detectors are

    • A.

      Ionization & Rate-of-rise

    • B.

      Ionization & Photoelectric

    • C.

      Photoelectric & Rate-of-rise

    • D.

      Rate-of-rise & Flame

    Correct Answer
    B. Ionization & Photoelectric
    Explanation
    Smoke detectors are devices that detect the presence of smoke in the air and trigger an alarm to alert occupants of a potential fire. Ionization smoke detectors use a small amount of radioactive material to ionize the air inside the detector. When smoke enters the detector, it disrupts the ionization process and triggers the alarm. Photoelectric smoke detectors, on the other hand, use a light source and a photosensitive sensor. When smoke particles enter the detector, they scatter the light, which is detected by the sensor, causing the alarm to sound. Therefore, the correct answer is Ionization & Photoelectric, as these are the two basic types of smoke detectors commonly used.

  • 5. 

          Photoelectric smoke detectors are

    • A.

      More sensitive to smoldering fires

    • B.

      Less sensitive to smoldering fires

    • C.

      Have the same reaction to smoldering fires

    • D.

      More responsive to flaming fires

    Correct Answer
    A. More sensitive to smoldering fires
    Explanation
    Photoelectric smoke detectors are more sensitive to smoldering fires because they use a light source and a light sensor to detect smoke particles. When smoke enters the detector, it scatters the light, causing the sensor to trigger the alarm. Smoldering fires produce larger smoke particles that are more easily detected by the photoelectric technology, making these detectors more responsive to this type of fire. On the other hand, ionization smoke detectors are more responsive to flaming fires, as they use a small amount of radioactive material to ionize the air and detect the changes in electrical current caused by smoke particles.

          Ionization smoke detectors are

    • A.

      More sensitive to smoldering fires

    • B.

      Have the same reaction to smoldering fires as photoelectric detectors

    • C.

      More responsive to flaming fires

    • D.

      Have the same reaction to flaming fires as photoelectric detectors

    Correct Answer
    C. More responsive to flaming fires
    Explanation
    Ionization smoke detectors are more responsive to flaming fires because they are designed to detect small particles of combustion that are produced by fast-burning, flaming fires. These detectors use a small amount of radioactive material to ionize the air inside the detector. When smoke enters the detector, it disrupts the ionization process, triggering the alarm. On the other hand, photoelectric detectors are more sensitive to smoldering fires, as they use a light source and a photosensitive sensor to detect the presence of smoke. When smoke particles enter the detector, they scatter the light, which then triggers the alarm.

          The value of automatic sprinklers in providing safety to the occupants of a structure include

    • A.

      Provides a better chance of survival for occupants on the upper floors

    • B.

      Discharges water directly into the fire

    • C.

      Products of combustion are limited

    • D.

      All of the above

    Correct Answer
    D. All of the above
    Explanation
    Automatic sprinklers provide safety to the occupants of a structure in multiple ways. Firstly, they provide a better chance of survival for occupants on the upper floors by quickly suppressing the fire and preventing it from spreading. Secondly, they discharge water directly into the fire, effectively extinguishing it. Lastly, they limit the products of combustion, reducing the amount of smoke and toxic gases that can harm the occupants. Therefore, the correct answer is "All of the above."

         Fire department connection is

    • A.

      Usually a Siamese connection with two 2 ½” female connections with a clapper valve or one clapper large-diameter inlet

    • B.

      Usually a Siamese with two 2 ½” male connections with a clapper valve or one clapper large-diameter inlet

    • C.

      Located outside the building

    • D.

      Both a & c

    Correct Answer
    D. Both a & c
    Explanation
    The correct answer is "Both a & c" because a fire department connection is usually a Siamese connection with two 2 ½” female connections with a clapper valve or one clapper large-diameter inlet. It is also located outside the building.

         Water flow alarm

    • A.

      Indicates a problem with the water flow to the sprinkler system

    • B.

      Located outside the building, usually close to the sprinkler connection

    • C.

      Indicates no water flow

    • D.

      Located inside the building on the sprinkler valve head

    Correct Answer
    B. Located outside the building, usually close to the sprinkler connection
    Explanation
    The correct answer is located outside the building, usually close to the sprinkler connection. This is because a water flow alarm is designed to indicate a problem with the water flow to the sprinkler system. It is typically installed outside the building near the sprinkler connection to monitor the flow of water and detect any potential issues such as a lack of water flow.

          The dry pipe sprinkler valve is equipped with an air pressure gauge above the clapper and a water pressure gauge below the clapper. The air pressure gauge will read.

    • A.

      The same as the water pressure gauge

    • B.

      Substantially lower than the water pressure gauge

    • C.

      Substantially higher than the water pressure gauge

    • D.

      None of the above

    Correct Answer
    B. Substantially lower than the water pressure gauge
    Explanation
    The air pressure gauge will read substantially lower than the water pressure gauge because in a dry pipe sprinkler system, the pipe is filled with pressurized air instead of water. When a fire is detected, the air pressure is released, allowing water to flow into the pipes and activate the sprinkler heads. Therefore, the air pressure gauge will show a lower reading compared to the water pressure gauge, which measures the water pressure in the system.
