• Model ESFR-17 sprinkler now FM Approved at 155 F and 205 F
• Designed for use in ceiling-only sprinkler systems within storage facilities
• Temperature and pressure features provide flexibility for sprinkler system designers

Johnson Controls, the global provider for smart, healthy, and sustainable buildings, announces FM Approval of the Tyco Model ESFR-17 Early Suppression, Fast Response Pendent Sprinkler at 205 F (96 C). Combined with the existing FM Approved lower-temperature version (155 F, 68 C), the ESFR-17 sprinklers now provide the options needed to help better protect storage and warehousing facilities. The sprinklers are also cULus Listed for both temperature ratings.

The Tyco® ESFR-17 Pendent Sprinklers are designed with flexibility in mind. The primary advantage is their ability to protect high-piled storage arrangements without the need for in-rack sprinklers. With a 16.8 K-factor and maximum working pressure of 175 psi (12,1 bar), the ESFR-17 sprinklers provide system designers with hydraulic and sprinkler placement options not presently available among traditional ESFR sprinklers with a nominal K-factor of 14.0.

With substantially lower-end head pressure, as compared to traditional ESFR sprinklers, the ESFR-17 sprinklers also offer flexibility when sizing system piping, as well as potentially reducing the need for a system fire pump. In addition to flexibility, these features also contribute to potential cost savings for building owners and operators. The ESFR-17 sprinklers help serve the Johnson Controls OpenBlue mission of supporting healthy people, healthy places, and a healthy planet.

“As the storage and warehousing industries expand along with consumer demand for shipped goods, so does the need to protect a wide variety of these applications,” said Don Ricca, director, Product Management, Johnson Controls. “Now that we can offer two FM Approved temperature ratings, we are confident that the ESFR-17 sprinklers can offer our customers the protection and flexibility needed to keep operations running safely and efficiently.”

The ESFR-17 pendent sprinklers are ideal for helping to protect storage facilities containing the following materials:

• Most encapsulated and non-encapsulated common materials, including cartoned, unexpanded plastics
• Cartoned and uncartoned expanded plastics
• Uncartoned unexpanded plastics
• Some storage arrangements of rubber tires, roll paper, and aerosols
