Johnson Controls, the global pioneer for smart, healthy, and sustainable buildings, introduces the Tyco Model ES-1 and ES-2 Sprinkler Shields for the protection of in-rack early suppression fast response (ESFR) sprinklers in storage facilities and warehouses.
The all-metal shields work to protect sprinkler elements from cold soldering, which occurs when cascading water from ceiling-mounted and high-mounted in-rack sprinklers cool down and inhibits the operation of in-rack sprinklers mounted at lower heights.
fire protection solution
As storage ceiling and rack heights continue to trend higher and hold higher-hazard material like non-expanded and expanded plastics, the need for in-rack sprinklers has increased. When used in conjunction with ceiling protection, in-rack ESFRs have become an integral component in an overall fire protection solution.
FM datasheets 8-9 and 8-34 now require that when multiple levels of ESFR sprinklers are used, the sprinklers below the highest level have shields to protect them from getting wet should a sprinkler above them operate.

“ESFR pendent sprinklers now have an FM Approved shield for in-rack storage applications to help ensure proper function when used in combination with ceiling protection,” said Don Ricca, global product director, Johnson Controls.
“The shields provide a dry atmosphere allowing sprinkler elements to operate as designed, even when surrounded by falling water from sprinklers mounted higher in the rack or on the ceiling.”
ES-1 and ES-2 Sprinkler Shields
The sprinkler shields are designed for use with Tyco Model ESFR pendent sprinklers. The ES-1 Shield is designed for a thread size of 3/4-inch and works with ESFR-14 and ESFR-17 sprinklers. The ES-2 Shield is designed for a thread size of 1-inch and works with ESFR-22 and ESFR-25 sprinklers.
Tyco ES-1 and ES-2 Sprinkler Shields are available zinc-coated or painted red, allowing for aesthetics that meet the needs of the operational space in which they are installed. The new Tyco Sprinkler Shields complement a full line of Johnson Controls fire suppression products. Together, they help serve the Johnson Controls mission of reimagining building performance to serve healthy people, healthy places, and a healthy planet.
