Tyco shields ensure ESFR sprinkler efficiency
01 March 2022
Johnson Controls a leading fire, HVAC, and security equipment provider, has introduced 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.
“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,” says Don Ricca, Global Product Director, Johnson Controls. “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, Ricca explains. The shields provide a dry atmosphere allowing sprinkler elements to operate as designed.
