  • 2. 

    Protected Premises Fire Alarm System is

    • Most basic

    • Designed to be initiated manually

    • Both a & b

    • Used at banks only

    Correct Answer
    A. 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.

    Two basic types of smoke detectors are

    • Ionization & Rate-of-rise

    • Ionization & Photoelectric

    • Photoelectric & Rate-of-rise

    • Rate-of-rise & Flame

    Correct Answer
    A. 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.

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

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

    • Discharges water directly into the fire

    • Products of combustion are limited

    • All of the above

    Correct Answer
    A. 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."

         Automatic Alarm Systems

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

    • Have a high degree of false alarms compared to other systems

    • Can only be manually activated

    • 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.

          Photoelectric smoke detectors are

    • More sensitive to smoldering fires

    • Less sensitive to smoldering fires

    • Have the same reaction to smoldering fires

    • 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

    • More sensitive to smoldering fires

    • Have the same reaction to smoldering fires as photoelectric detectors

    • More responsive to flaming fires

    • Have the same reaction to flaming fires as photoelectric detectors

    Correct Answer
    A. 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.

         Fire department connection is

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

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

    • Located outside the building

    • Both a & c

    Correct Answer
    A. 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.

    Which type of fire suppression system is most suitable for a computer server room?

    • Wet pipe sprinkler system 

    • Dry pipe sprinkler system 

    • Clean agent suppression system 

    • Carbon dioxide suppression system

    Correct Answer
    A. Clean agent suppression system 
    Explanation
    Clean agent suppression systems use gaseous fire extinguishing agents that do not leave residue or damage sensitive equipment, making them ideal for protecting electronic systems in computer server rooms. Wet and dry pipe sprinkler systems use water, which can cause significant damage to electronics. Carbon dioxide systems, while effective, can pose a risk of asphyxiation to personnel.

         Water flow alarm

    • Indicates a problem with the water flow to the sprinkler system

    • Located outside the building, usually close to the sprinkler connection

    • Indicates no water flow

    • Located inside the building on the sprinkler valve head

    Correct Answer
    A. 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.
