The given answer "nozzle" is correct because a nozzle is a device that is designed for use in situations that require a special water discharge pattern, directional spray, or any other unusual discharge characteristics. It is similar to the type used in water spray fixed systems. Nozzles are commonly used in various applications such as firefighting, irrigation, and industrial processes to control and direct the flow of liquids.

The given answer, 82, suggests that the installation of residential fire sprinklers in one and two family dwellings can reduce 82% of fire deaths. This implies that fire sprinklers are highly effective in preventing and controlling fires, leading to a significant decrease in fatalities caused by fires in residential settings.

NFPA 13 is the section of the National Fire Protection Association (NFPA) that specifically defines automatic sprinkler systems. This section provides guidelines and requirements for the design, installation, and maintenance of these systems. It covers various aspects such as sprinkler types, spacing, water supply, and system components. By following the guidelines outlined in NFPA 13, professionals can ensure the effective and safe operation of automatic sprinkler systems in buildings.

Pendent sprinklers are installed downward from the branch line, allowing water to flow from the sprinkler and strike the deflector. This deflector then distributes the water over the protected area. This type of sprinkler is commonly used in fire protection systems to effectively cover a large area and provide efficient water distribution for fire suppression.

During the installation of fire-protection systems, it is important for the inspector to compare the components of the system to those shown on the plans or listed in the construction documents. This ensures that the installation is being done according to the specified design and requirements. By referring to the plans and construction documents, the inspector can verify that the correct components are being used and that the system is being installed correctly. This helps to ensure the effectiveness and compliance of the fire-protection system.

An ornamental or decorative type of sprinkler is specially painted or plated by the manufacturer to match the decor of the surrounding area. This means that the sprinkler is designed to not only function effectively but also blend in with the aesthetic of its environment. It is likely to have a visually pleasing appearance and may have decorative elements or finishes that make it more visually appealing. This type of sprinkler is ideal for areas where both functionality and aesthetics are important, such as gardens, parks, or upscale outdoor spaces.

Standpipe and hose systems are designed to quickly deploy fire hoses and operate fire streams in multistory structures and large area structures. These systems provide a reliable and efficient means of delivering water to different levels and remote points in a building or facility. They are essential for firefighters to effectively combat fires in high-rise buildings and other large structures. Water mist systems, water spray fixed systems, and foam water systems may have their own applications and benefits, but they do not specifically address the need for rapidly deploying fire hoses and operating fire streams in multistory structures and large area facilities.

Check valves are used to limit the flow of water to one direction and prevent recirculation or backflow of water from the sprinkler system into the municipal water supply system. They act as a one-way valve, allowing water to flow in one direction but preventing it from flowing back in the opposite direction. This helps to maintain the integrity and safety of the water supply system by ensuring that contaminated water from the sprinkler system does not enter the municipal supply. Therefore, check valves are the correct answer in this context.

An open sprinkler refers to a type of sprinkler that does not have a thermal or heat responsive element or plug. It has an open orifice, allowing water to flow freely without any obstruction. This design ensures that the sprinkler continuously releases water, providing a constant water supply for firefighting purposes. Unlike other types of sprinklers, an open sprinkler does not rely on heat activation to initiate water discharge. Instead, it is always ready to release water when needed.

A sidewall sprinkler is a type of sprinkler that is mounted horizontally from a wall face. The deflector of the sprinkler causes the water to be distributed in an arc over the protected area, while a portion of the spray is directed at the supporting wall face. This type of sprinkler is commonly used in buildings where a standard ceiling-mounted sprinkler is not possible or desired. It provides effective fire protection while also ensuring that water is directed towards the wall to help prevent fire spread.

A manually activated system is a type of sprinkler activation device that relies on human intervention to operate the sprinkler system. This means that a worker or individual must physically activate the system before a fire or hazardous situation occurs. This type of system is commonly used in situations where there is a risk of a gas or liquid release, allowing for immediate response and prevention of a potential disaster.

A corrosion-resistant sprinkler is made of stainless steel or coated with materials such as wax, asphalt, lead, enamel, polyester, or Teflon. This type of sprinkler is designed to withstand exposure to acids or caustic materials, making it suitable for installation in areas where these substances are present. The corrosion-resistant coating or material helps to protect the sprinkler from damage and ensures its longevity in such environments.

A looped sprinkler system is a type of sprinkler system where the branch lines are not interconnected. In this system, each branch line is connected to the main line independently, forming a loop-like configuration. This allows for better water distribution and pressure throughout the system, as water can flow in both directions. It also provides redundancy, as if one branch line fails, the others can still function. This design is commonly used in large or complex irrigation systems to ensure efficient and reliable water distribution.

A pendent sprinkler is installed downward from the branch line, allowing water to flow from the sprinkler and strike the deflector. This deflector then distributes the water over the protected area. The term "pendent" refers to the fact that the sprinkler hangs down from the branch line, as opposed to being flush with the ceiling or wall.

Deluge or preaction type sprinklers operate when an electronic detector or manual control device is activated. This means that these sprinklers do not automatically respond to heat from a fire or smoke coverage. Instead, they require a specific trigger, such as an electronic detector sensing a fire or a manual control device being activated by a person, to start operating. Once activated, these sprinklers release water or other extinguishing agents to suppress the fire. This method allows for a more controlled and intentional activation of the sprinkler system, making it suitable for certain environments or situations where false alarms or accidental activations need to be minimized.

A wet-pipe sprinkler system is the correct answer because it is continually charged with water under pressure, ready to discharge immediately when one or more sprinklers are activated by heat from a fire. This type of system is commonly used in buildings where the risk of freezing is low, as the water is always present in the pipes and can quickly suppress a fire.

Water mist systems are a type of water-based fire-suppression system that are designed to control, contain, or extinguish fires in the incipient stage. These systems use fine water droplets to create a mist that can quickly cool down the fire and displace oxygen, effectively suppressing the flames. Water mist systems are particularly effective in suppressing fires in enclosed spaces or areas with sensitive equipment, as the fine mist reduces the risk of water damage.

Sprinklers are rated based on their activation temperatures. This means that each sprinkler is designed to activate and release water when the surrounding temperature reaches a specific threshold. The activation temperature is determined based on the type of fire that the sprinkler system is intended to suppress. By rating sprinklers according to their activation temperatures, it ensures that the appropriate sprinkler is used in different environments to effectively control and extinguish fires.

A standpipe system is a type of fire protection system that consists of vertical pipes that are connected to a water source. In a manual-dry standpipe system, the pipes are not filled with water and there is no permanent water supply. Instead, the system relies on firefighters to manually connect hoses to the standpipe and supply water from an external source, such as a fire engine. This type of system is typically used in buildings where water is not readily available or where freezing temperatures could cause the water in the pipes to freeze and potentially damage the system.

The correct answer is "obtain permission from the owner/occupant." Before performing any inspection, it is essential for the inspector to obtain permission from the owner or occupant of the property. This ensures that the inspector has legal access to the premises and respects the rights of the owner/occupant. It is important to have the owner/occupant's consent before conducting any inspection to maintain a professional and ethical approach.

This type of sprinkler is designed specifically for use in high rack storage spaces. It is equipped with shields to protect it from being affected by the operation of sprinklers at a higher level. Therefore, the correct answer is "intermediate level or rack storage".

The correct answer is upright because an upright sprinkler is designed to be installed on a riser nipple above the branch line. It discharges water vertically into the deflector, which then causes the water to rain down in a circular pattern. This type of sprinkler is commonly used in fire protection systems to provide efficient coverage and distribution of water.

The minimum sprinkler pipe size that may be used in a residential system is 1/2. This size is determined by the flow rate and pressure requirements of the sprinkler system. A larger pipe size allows for better water flow and pressure, ensuring that the sprinklers can effectively and efficiently distribute water in case of a fire. Using a smaller pipe size may result in inadequate water flow and pressure, compromising the system's effectiveness.

Sprinklers that are kept closed by fusible links or other thermally sensitive devices are activated automatically by heat from a fire. When the temperature in the vicinity of the sprinkler reaches a certain threshold, the heat causes the fusible link or thermally sensitive device to melt or activate, which in turn releases the mechanism holding the sprinkler closed. This allows water to flow through the sprinkler and extinguish the fire. The activation of the sprinkler is solely dependent on the heat generated by the fire and not by any other factors such as pressure, smoke coverage, electronic detectors, or manual control devices.

A post indicator valve (PIV) is a type of water control valve that has a hollow metal post attached to the valve housing. Inside the post, there is a valve stem with a target that displays the words OPEN or SHUT. This allows the valve to be easily operated and visually indicates the position of the valve. The PIV is commonly used in fire protection systems to control the flow of water in case of emergencies.

Foam water systems are designed to control, contain, or extinguish Class A or Class B fires by discharging water, foam, or water and foam intermittently. These systems are effective in suppressing fires by creating a foam blanket on the burning surface, which helps to smother the fire and prevent re-ignition. The foam water systems are commonly used in various industrial settings, such as oil refineries, chemical plants, and storage facilities, where flammable liquids or solids are present.

The correct answer is the system riser room. This is because the system riser room is where the main components of the water-based fire-suppression system are located, such as the riser, valves, and control panel. Inspecting this room first allows the inspector to assess the overall condition and functionality of the system before moving on to other areas. Additionally, starting in the system riser room ensures that any issues or maintenance needs can be identified and addressed early on in the inspection process.

The correct answer is institutional. This type of sprinkler is specifically designed for use in prisons, jails, or facilities that house the mentally ill. It is designed to be damage resistant with no removable parts. The term "institutional" accurately describes this type of sprinkler system as it is specifically tailored for use in such institutional settings.

Drain valves are used to remove water from piping systems when the pressure is relieved in the pipe. They can be either main drains or auxiliary valves. Main drains are typically located at the lowest point in the system and are used to completely drain the system. Auxiliary drain valves are used for partial draining or to drain specific sections of the piping. Overall, drain valves are essential for maintaining the integrity and functionality of piping systems by preventing water buildup and potential damage.

The correct answer is "large drop". This refers to a type of sprinkler that is specifically designed and listed to produce large water droplets. These sprinklers are intended for use in high challenge hazards where a greater amount of water is needed to suppress the fire. The large droplets help to penetrate the fire plume more effectively and provide better cooling and extinguishing capabilities.

The correct answer is Early suppression fast-response (ESFR). ESFR sprinklers are specifically designed to suppress fires in high-challenge hazards such as warehouses. They have a fast response time and are capable of delivering high water flow rates to quickly control and extinguish fires in these types of environments.

The water supply for an automatic sprinkler system must maintain a minimum residual pressure in order to ensure that the highest or most remote sprinkler in the structure receives enough water. This is because the highest or most remote sprinkler will typically experience the greatest pressure drop due to friction and distance from the water source. By maintaining a minimum residual pressure, the system can ensure that even the sprinkler with the greatest pressure drop still receives enough water to effectively extinguish a fire.

A concealed sprinkler is a type of sprinkler that is recessed and covered with a removable decorative cover plate. This cover plate releases when exposed to a specific level of heat. This design allows the sprinkler to blend in with the ceiling and remain hidden until activated, providing a more aesthetically pleasing appearance.

The correct answer is early suppression fast response (ESFR). This type of sprinkler is specifically designed to suppress fires in high challenge hazards like warehouses. It was developed based on research into residential sprinklers that need to react quickly to protect life in the room where the fire originated. The early suppression fast response sprinkler is capable of quickly suppressing fires in these challenging environments, making it an effective choice for such applications.

Fire pumps are installed in structures and facilities to increase the static or existing water pressure within a water-based fire-suppression system. These pumps are designed to provide a reliable and consistent water supply to the system, ensuring that an adequate amount of water is available to fight fires effectively. Fire pumps are typically powered by electricity or diesel engines and are capable of delivering high-pressure water flow to sprinkler systems, standpipe systems, and other fire-fighting equipment. They play a crucial role in maintaining the functionality and effectiveness of the fire-suppression system.

Check valves are used in automatic sprinkler system valves to limit the flow of water to one direction. These valves allow water to flow in one direction and prevent backflow, ensuring that water does not flow back into the system. This is important in sprinkler systems to maintain water pressure and prevent contamination of the water supply. Drain valves are used to drain water from the system, globe valves control the flow of water, and ball-drip valves are used to release excess pressure.

The first step in performing a main drain test is to observe and record the pressure on the system side gauge at the system riser. This is important because it allows the tester to establish a baseline pressure reading before conducting the test. By observing and recording this initial pressure, any changes or drops in pressure during the test can be accurately measured and assessed.

Private water mains are flow tested at a minimum of every five years to ensure their functionality and safety. This regular testing allows for the detection of any potential issues or blockages in the water mains, ensuring that they can continue to provide a reliable water supply to the surrounding areas. By conducting these tests every five years, any necessary maintenance or repairs can be identified and carried out promptly, preventing any major disruptions or hazards. This periodic flow testing helps to maintain the quality and efficiency of private water mains, ensuring the uninterrupted supply of clean water to consumers.

The correct answer is "dry" because this type of sprinkler is specifically designed for use in dry systems where the protected area may freeze, such as walk-in freezers in grocery stores. It is attached to a dry riser nipple and separated from a wet branch line by a pressure seal. The term "dry" in this context refers to the absence of water in the system until the sprinkler is activated. This type of sprinkler is corrosion resistant and suitable for use in institutional or intermediate level or rack storage settings.

Entrance hallways can have sprinklers omitted in one and two-family dwellings because they are not considered high-risk areas for fire hazards. Kitchens, living rooms, and bedrooms are more prone to fires due to cooking activities, electrical appliances, and flammable materials, respectively. Therefore, it is important to have sprinklers installed in these areas to ensure the safety of the occupants and minimize property damage in case of a fire.

Alarm test valves are located on the riser and are used to flow water for the purpose of testing the water flow alarm. They perform a similar function to the inspector's test valve, which is typically located at a remote part of the system piping. However, the code no longer requires the inspector's test valve to be located at a remote location from the riser. Therefore, alarm test valves are the correct answer as they are specifically designed for testing the water flow alarm.

The correct answer is 144, 12, 6. In residential systems, the maximum spacing for sprinklers is 144 square feet per sprinkler. The maximum spacing between sprinklers is 12 feet. The maximum allowable distance of a sprinkler from a wall is 6 feet.

A preaction sprinkler system is a type of automatic sprinkler system that is charged with air, which may or may not be under pressure. It operates when both a sprinkler opens and a detection device in the same area activates the water-flow control valve. This system is commonly used in areas where water damage needs to be minimized, such as data centers or museums, as it provides an additional layer of protection by requiring two separate events to occur before water is released.

A multicycle sprinkler system is designed to operate repeatedly in response to a detection device. This means that once the detection device senses a fire or smoke, the sprinkler system will activate and release water to extinguish the fire. After the fire is extinguished, the system can be reset and used again in case of another fire emergency. This makes the multicycle sprinkler system a reliable and efficient option for fire protection in various settings.

Institutional sprinkler variations are designed to be damage resistant with no removable parts. This means that these sprinklers are built to withstand potential damage and do not have any parts that can be easily removed or tampered with. This makes them suitable for use in institutional settings where durability and security are important factors.

The correct answer is "extended coverage." An extended coverage sprinkler is designed to cover a larger area, in this case, a 20 feet by 20 feet area. It is specifically designed to provide adequate water distribution and coverage over a larger space, ensuring efficient fire suppression.

The statement that the inspector never performs this test due to liability issues means that the responsibility of performing the alarm trip test does not fall on the inspector. This could be because performing the test involves certain risks or potential legal consequences, and therefore it is not within the inspector's scope of duties.

Globe valves are designed as small hand wheel type valves that typically turn counterclockwise to open and clockwise to close. They are commonly used as drains and test valves. The inspector's test valve, which is usually a globe valve, can be located at a remote location within a sprinkler system. Therefore, globe valves are the correct answer in this case.

Water mist systems are most likely to be used to protect computer equipment and rooms because they provide a fine mist of water droplets that quickly evaporate, suppressing fires without causing damage to sensitive electronics. These systems are highly effective in extinguishing fires and preventing re-ignition, making them a suitable choice for protecting computer equipment and rooms. Foam-water systems, water spray fixed systems, and standpipe and hose systems may not be as suitable for this specific purpose.

A recessed sprinkler is a type of sprinkler that is installed within a recessed housing in the ceiling of a compartment or space. The sprinkler is mounted in the housing, with only the threaded shank being visible. This type of sprinkler is designed to be discreet and blend in with the surrounding ceiling, providing a more aesthetically pleasing appearance. It is commonly used in spaces where a more seamless and integrated sprinkler system is desired.
