Nearly all fire sprinklers are composed of the same components: a sealing assembly or ‘plug’ that prevents water from escaping, a heat-sensitive element that breaks or melts at a given temperature to allow water flow, a deflector that distributes the water effectively, and a frame that holds all these parts. Fire sprinkler heads feature heat-sensit...
A fire sprinkler’s temperature rating is the temperature at which the sprinkler will activate, which closely tracks rising ceiling temperatures. Options range from 135 to 650 degrees Fahrenheit (38 to 343 degrees Celsius). These ratings can be identified by the color of the liquid inside the bulb in the case of glass-bulb sprinklers, or the color-c...
Fire sprinklers with bigger K-factors have a larger orifice, allowing them to discharge more water at a specific pressure and to produce bigger water droplets that are more capable of penetrating fires. The most common K factors are 5.6k for fire sprinklers with a 1/2″ (12.7mm) thread connection and 8.0K for fire sprinklers with a 3/4″ (19.1 mm) th...
A pendent (sometimes incorrectly spelled “pendant”) fire sprinkler hangs from above-ceiling pipes and distributes water in a domed or conical pattern using a convex deflector. Unlike concealed pendent sprinklers which hide behind decorative plates, the head of a traditional pendent fire sprinkler remains visible after installation. Major manufactur...
Upright fire sprinklers spray water upward to a concave deflector, producing a dome-shaped spray pattern. They install deflector-up to cover specific areas and to prevent ice and debris from collecting in the head. Upright sprinklers are installed where obstructions interfere with coverage in many system types and in dry-pipe systems facing freezin...
Sidewall fire sprinklers install along walls or beneath beams where ceiling piping is unavailable, or where aesthetic concerns or obstructions weigh against the use of other sprinkler types. Most are designed to protect small rooms, closets, or hallways and have a semicircular deflector that produces a crescent-shaped spray pattern. Horizontal side...
Concealed models install in walls or ceilings and fully cover a pendent or sidewall sprinkler head using a concealed fire sprinkler cover plate. This heat-sensitive plate detaches at temperatures roughly 20 degrees (F) lower than the fire sprinkler head, allowing the concealed sprinkler’s deflector to drop and the head to activate. Like pendent, up...
The sprinkler head types discussed above are far from the only options available. Over the years, manufacturers like Tyco have developed many specialty sprinkler heads for very specific applications. Extended Coverage Light Hazard (ECLH), Extra Large Orifice (XLO), vertical sidewalls, and mist systems are each well-suited to specific environments a...
