What is the difference between quick response and standard response sprinkler?
Physically, the only difference between a standard response fire sprinkler and a quick response fire sprinkler is the size of the bulb—standard response sprinklers have a 5-mm glass bulb, while quick response fire sprinklers have a 3-mm glass bulb.
What is fast response sprinkler?
Quick response sprinkler heads activate quickly, but they also work to discharge water higher up on the ceiling than a standard sprinkler head. This cools the ceiling and surrounding walls, helping prevent flash-over and keeping the fire from rising in temperature and severity.
What does SSU mean in fire protection?
Marked “SSU” (Standard Sprinkler Upright) or “UPRIGHT” on the deflector. PENDENT SPRINKLER: A sprinkler intended to be oriented with the deflector below the frame so water flows downward through the orifice, striking the deflector and forming an umbrella-shaped spray pattern downward.
What is sprinkler K factor?
In fire protection engineering, the K-factor formula is used to calculate the discharge rate from a nozzle. Spray Nozzles can be fire sprinklers or water mist nozzles, hose reel nozzles, water monitors and deluge fire system nozzles.
What is ESFR fire protection?
ESFR (Early Suppression, Fast Response) ceiling mounted sprinklers can be used in warehouses in place of in-rack fire sprinkler systems. ESFR provides protection that exceeds that of in-rack systems. ESFR high output, high volume systems are located in ceiling spaces as with conventional fire sprinkler systems.
Are residential sprinklers quick response?
As residential sprinklers are not quick response sprinklers, the remote area reduction for the use of quick-response sprinklers does not apply. These reductions can significantly reduce the flow for a remote area, resulting in less friction loss and ultimately a smaller system demand, even with smaller pipe sizes.
What is standard response sprinkler?
Standard response sprinkler systems are designed to suppress and limit the spread of fire by wetting the area surrounding a flame to remove a fire’s fuel source.
What does Afss stand for?
What is a Annual Fire Safety Statement (AFSS)? A document to ensure fire safety and egress measures are operating as required in all buildings across NSW.
What pressure are fire sprinkler heads rated to?
➢ Fire sprinklers typically require only 7 pounds-per-square-inch (psi) to operate, which is less than the minimum required pressure for residential plumbing fixtures.
What K-factor is 17 32?
In contrast, a 17/32” sprinkler with a K-factor of 8.0 GPM/psi1/2 (115,2 LPM/bar1/2), which will only discharge 67 gpm (253,6 lpm) or only a . 67 gpm/ft2 (27,2 mm/min) over a coverage area of 100 ft2 (9,29 m2) per sprinkler.
How do I choose sprinkler K-factor?
K-factors can be determined by using the following equation: K = Q/P1/2, where K is represented by gallons per minute, or gpm/psi1/2, Q is flow rate in gpm and P is pressure in psi, or pounds of force.
Are ESFR sprinklers considered quick response?
Early Suppression Fast Response (ESFR) systems are quick responding, high volume sprinkler systems that provide exception protection for high piled storage occupancies.

What is a fast response sprinkler?
A fast-response element is a fusible link or bulb that responds more quickly to temperature changes. Quick response sprinklers are nearly identical to standard response (SR) sprinklers—the only difference is the fast-response element.
What are the different styles of quick response fire sprinkler heads?
Quick response fire sprinkler heads are available in many different styles, temperatures, and colors. While various styles are available, the four most common styles for quick response sprinklers include: • Concealed pendent: installs in ceilings with the head hidden from view
What temperature does a quick response fire sprinkler head activate?
The temperature at which a quick response fire sprinkler head activates depends on building usage, ambient temperature, the presence of nearby heat sources, and location. The most common temperature is 155 degrees Fahrenheit, but 200 and 286 degrees are also prevalent.
