Johnson Controls offers two Tyco early-suppression, fast-response (ESFR) Rapid Install Sprinklers (RIS) for protection of warehouse and storage facilities. The Model ESFR-22 and Model ESFR-25 pendent sprinklers, and their accompanying custom welded outlet fitting, simplify installation for fire protection contractors by featuring pre-installed rubber gaskets and a thread connection that can be installed by hand with no need for tools, tape or sealant. Both sprinklers provide warehouse design flexibility by eliminating the use of in-rack sprinklers when protecting high-piled storage.
