Sprinkler System

Sprinkler System

General Description TYCO Model FH-1 Flexible Hose can be used in wet sprinkler systems between the branch line and sprinkler when installed in accordance with NFPA 13, 13D, and 13R. Flexible Hose provides a unique sprinkler drop assembly comprised of the following components :

• Stainless steel flexible hose with two slip nuts
• Branch line inlet nipple
• Straight sprinkler reducer
• Reducer bracket, bar fixing clamps, and support bar

Using Model FH-1 Flexible Hose saves time and cost because the system can be installed in false ceilings without cutting and threading pipes associated with installing a drop, arm-over, and elbows. Model FH-1 Flexible Hose makes it possible to test and charge the system with water before installing the ceiling grid. After the ceiling grid is in position, the Model FH-1 Flexible Hose can be reshaped to suit the final sprinkler location without draining the system.
