Description

TYCO Model ESFR-34 Pendent Sprinklers are Early Suppression, Fast Response Sprinklers having a nominal K-factor of 33.6 (See Figure 1) They are suppression-mode sprinklers that are especially advantageous as a means of eliminating the use of in-rack sprinklers when protecting high-piled storage The Model ESFR-34 Sprinklers are primarily used for ceiling-only sprinkler protection of (but not limited to) the following storage applications: • most encapsulated or non-encapsulated common materials including cartoned, unexpanded plastics • uncartoned (exposed) expanded plastics in accordance with FM Global standards • some storage arrangements of rubber tires, roll paper, flammable liquids, and aerosols For more specific criteria, refer to Table B as well as the applicable design standard The Model ESFR-34 can protect a storage arrangement of 50 ft (15,2 m) with a ceiling height of 55 ft (16,8 m) without requiring in-rack sprinklers In addition, it can be installed with a maximum centerline of thermal sensing element-to-ceiling distance of 17 in (432 mm)
