HL-22 Specific Application ESFR Pendent Sprinklers. RTI is a measure of how thermally responsive the heat-responsive element of the sprinkler is, measured as the time needed to raise the temperature of the sprinkler bulb to 63% of the temperature of the hot air stream times the square root of the velocity of the air stream. View Product. 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 allows water to flow at a given temperature, a deflector that distributes water effectively, and a frame. Research over the past three decades shows that these extra seconds can have serious implications for human survival during a fire. – Fri: 8AM – 5PM Weekends: Closed Contact Us, Designed by Spectrum Fire Protection | 2018.

Because they’re smaller than the 5mm bulbs used in standard response sprinklers, 3mm glass bulbs are more sensitive to changes in heat and thus discharge earlier than standard-response heads. While aftermarket paints ruin fire sprinkler heads, manufacturer-supplied coatings can extend their longevity by protecting against corrosion. They are used in hotels, restaurants, churches, and a range of commercial structures and most sidewall fire sprinklers utilize a 1/2″ (12.7 mm) thread connection and feature a 5.6 K-factor. Each closed-head sprinkler is held closed by either a heat-sensitive glass bulb (see below) or a two-part metal link held together with a fusible alloy such as Wood's metal[21] and other alloys with similar compositions. Senju cover plates in a variety of finishes. The Concealed Pendent Sprinklers all produce a hemispherical water distribution pattern below the deflector. Response times vary according to the characteristics of the room and the fire, but differences in thermal sensitivity between these sprinkler types can lead to activation times that differ by ten seconds or more.

Most fire sprinklers are available in two primary sizes: 1/2″ (12.7 mm) and 3/4″ (19.3 mm). 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. The system pipework is charged with water under pressure at all times. Certain states, including California, Pennsylvania and Illinois require sprinklers in at least some new residential construction. For the complete system, see, Component that discharges water to protect buildings, "Domestic and Residential Fire Sprinkler Information", "Builders Smokin' Mad Over New Sprinkler Rules", "History of modern fire sprinkler systems, and how they prevent fire? Extended Coverage Light Hazard (ECLH), Extra Large Orifice (XLO), vertical sidewalls, and mist systems are each well-suited to certain environments and fire hazards. ESFR sprinkler heads were developed in the 1980s to take advantage of the latest fast-response fire sprinkler technology to provide fire suppression of specific high-challenge fire hazards. The majority of automatic fire sprinklers operate individually in a fire. Licensed fire sprinkler designers and installers are key to ensuring that the sprinkler type, location, and temperature are customized to the fire hazard, occupancy type, and architectural design of a structure.

Upright sprinklers are installed where obstructions interfere with coverage and in dry-pipe systems facing freezing temperatures. The frame at the core of each fire sprinkler is manufactured in a process called metal casting, where liquid metal takes shape as it cools inside a hollow mold.
