Upright fire sprinklers are often used in warehouses or industrial spaces, along with renovated open-ceiling structures such as modern office buildings and chic restaurants. This heat-sensitive plate detaches at temperatures roughly 20 degrees lower than the fire sprinkler head, allowing the concealed sprinkler’s deflector to drop and the head to activate. Fire sprinklers with bigger K-factors have a larger orifice, allowing them to discharge more water at lower pressure and to produce bigger water droplets that are more capable of penetrating fires. While all types of fire sprinklers bear a close resemblance to one another, different fire sprinkler heads are designed for different environments and different applications, and require careful consideration. 3/4″ sprinklers, on the other hand, are used when larger quantities of water are necessary.

Rising temperatures cause the alloy to melt, allowing the metal elements to fall from the sprinkler head and activate the sprinkler. These two types of sprinklers, however, bear more slight differences than their opposing operating arrangement. All wet-pipe sprinklers are held closed by either a fusible link or a glass bulb that contains a heat-sensitive liquid. Because each sprinkler activates independently when the predetermined heat level is reached, the number of sprinklers that operate is limited to only those near the fire, thereby maximizing the available water pressure over the point of fire origin. Certain states, including California, Pennsylvania and Illinois require sprinklers in at least some new residential construction. The pendant fire sprinkler head is one of the most common types that you will see. This company was founded in 1870 by the Textile Manufacturers' Associations of Lancashire and Yorkshire as a protest against high insurance rates. View Product.
