What is an ESFR?
Early Suppression Fast Response (ESFR) systems are quick responding, high volume sprinkler systems that provide exception protection for high piled storage occupancies.
Is Esfr wet or dry?
Early Suppression, Fast Response (ESFR) The Model ESFR-17 Dry Type Sprinklers are primarily used for ceiling only sprinkler protection and used to protect solid piled, palletized, and rack storage that is subject to freezing temperatures.
How does an ESFR system work?
How do they work? ESFR sprinklers are designed to release 2-3 times the amount of water of conventional sprinkler heads and to emit larger droplets of water, which in turn have a greater momentum than droplets emitted from conventional heads.
Are ESFR sprinklers considered quick response?
Quick response, residential, and early suppression fast response (ESFR) fire sprinklers all use “fast-response” elements, making them all “fast-response sprinklers.” A fast-response element is a fusible link or bulb that responds more quickly to temperature changes.
What is a CMSA sprinkler?
Control mode specific application (CMSA). CMSA sprinklers refer to a specific type of sprinkler listed for storage applications with increased severity fires.
How close can ESFR heads be together?
New ESFR Installations: The designer is constrained by a maximum spacing of 10 feet between sprinklers, a minimum spacing of 8 feet between sprinklers, and a 12-inch horizontal clearance required from every steel member.
Can ESFR sprinklers be used in a dry system?
ESFR Dry sprinklers can ONLY be installed in Wet systems! Not for installation in dry or preaction systems.
What is ESFR sprinkler?
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.
What is an ESFR sprinkler?

What is the minimum distance between a sprinkler head and any obstruction?
In short the “beam rule” states that there must be at least 1 foot (0.3048 m)of separation between the sprinkler and the obstruction if the deflector is any distance above the bottom of the obstruction.
