It is not for certain, however it is likely that the thinner of the two is a "quick responce (QR), or "fast responce (FR)"Sprinkler head. the larger of the two is a "standard responce most commonly used until recent years. Should be verified with the manufacturer, because it could also just be a result "lean" manufacturing.
Also note that FR, or QR heads should not be intermixed in the same room as standard. they have different responce times and thus the room realy should be all one or the other.

What do the colors of glass bulb sprinkler heads mean?
The colors of glass bulb sprinkler heads indicate the temperature at which the bulb will break, triggering the sprinkler system. Typically, the colors range from red for the lowest activation temperature (around 155°F or 68°C) to blue for higher temperatures (up to 286°F or 141°C). This color-coding helps ensure that the sprinkler activates appropriately based on the specific fire safety requirements of different environments.
What has a low melting point and is useful in sprinklers?
modern automatic sprinklers use a glass bulb that is filled with a fluid that boils and expands at a preset temperature. the glass bulb has a small bubble in the fluid. when a fire causes the fluid to boil, it shatters the glass bulb, which is keeping the waterway seal of the sprinkler in place. When the seal is gone, water can flow through the sprinkler orfice, and extinguish the fire. older sprinkler models use a link and lever arrangement, with a link of solder that melts at a preset temperature. The link and levers of the sprinkler mechanically hold the waterway seal of the sprinkler closed. When the link melts, the mechanical seal is gone, and water can flow through the orfice.
Is there a way to determine if the amount of fluid in a glass bulb fire sprinkler is the appropriate amount?
Yes, you can determine if the fluid in a glass bulb fire sprinkler is appropriate by visually inspecting the bulb for any signs of damage or leakage. The liquid inside the bulb should be at a specific level, typically indicated by a mark on the bulb itself. Additionally, manufacturers often provide specifications regarding the fill volume, which can be compared against the measured amount if the bulb is tested or replaced. If in doubt, it is best to consult with a fire protection professional or replace the sprinkler.
How do you replace glass bulb in fire sprinklers head?
To replace a glass bulb in a fire sprinkler head, first ensure the system is depressurized and water supply is shut off. Carefully remove the damaged sprinkler head from its fitting, then replace the broken glass bulb with a new one of the same type and rating. Reassemble the sprinkler head, ensuring all components are securely fastened, and then reinstall it. Finally, restore the water supply and check for any leaks before testing the system.
What is sprinkler with Quartzite bulb?
A sprinkler with a quartzite bulb is a type of fire sprinkler system that utilizes a quartzite glass bulb to detect heat. When the temperature rises to a certain level due to a fire, the quartzite bulb expands and shatters, allowing water to flow from the sprinkler head and extinguish or control the fire. This system is commonly used in various buildings for fire protection due to its reliability and effectiveness. The quartzite bulb is known for its durability and ability to withstand harsh conditions before activation.
What type of liquid use in sprinkler glass?
Sprinkler glass bulbs typically contain a glycerin-based liquid. This liquid expands when heated, causing the bulb to shatter and activate the sprinkler system. The glycerin is chosen for its reliable thermal expansion properties, ensuring the system responds effectively to fire conditions.
What is aStandard response fire sprinkler?
Standard response (SR) sprinkler heads are best suited for commercial or industrial buildings, including factories and warehouses. They activate individually to prevent causing water damage where there is no fire present. SR sprinklers take longer to activate than quick response sprinklers, requiring the heat from a fire below to reach a higher temperature before the liquid inside the bulb expands, the glass breaks, and water flows through the sprinkler head. SR sprinklers contain 5 mm glass bulbs that take longer for the expanding liquid inside to burst them. That said, these sprinkler heads still react within seconds, quickly dousing any fire.
What is the liquid in a frangible - bulb fire sprinkler?
The glass bulb inside a fire sprinkler head is filled with a heat sensitive liquid (e.g., glycerine) that expands faster than the glass bulb as it gets hotter. Eventually, it expands so much that it causes the glass bulb to burst, releasing the water behind it.The different colors of liquid contained within the bulb correlate to the temperature at which the sprinkler head will activate:Orange - 135oFRed - 155oFYellow - 174oFGreen - 200oFBlue - 286oFPurple - 360oFBlack - 440OFDifferent colors are used in different environments depending on the average ambient heat in said environment. For instance, if you have a storage facility that needs to be kept at temperatures higher than 135 F, you can imagine why you wouldn't want a orange-bulbed fire sprinkler!
What temperature does red bulb break in fire sprinkler system?
68 degree centigrade needs to break the red bulb in the fire sprinkler.
What is life of liquid bulb fire hydrant sprinkler?
The life of a liquid bulb fire hydrant sprinkler typically ranges from 10 to 25 years, depending on factors such as environmental conditions, maintenance, and the specific materials used in its construction. These sprinklers use a glass bulb filled with liquid that expands and shatters at a predetermined temperature, activating the sprinkler. Regular inspection and maintenance are essential to ensure functionality and compliance with safety standards. Ultimately, proper care can extend the effective lifespan of the system.
What are the different types of sprinklers?
The term sprinklers typically refers to devices that discharge water for irrigation or fire control applications. Irrigation sprinkler systems can be either manual or automatic. Three common types of irrigation sprinkler heads are sprays, rotors (impact or gear drive), and multi-stream rotators. Fire sprinkler systems types include wet pipe, dry pipe, deluge, pre-action, foam water, and water spray. Common types of fire sprinkler heads are bulb, upright, pendant and side wall.
What is the glass around a light bulb called?
The glass covering a light bulb is called a bulb or bulb glass, which protects the filament and controls the direction of light emitted.
