FASTFLEX Model YN25, YB25, and YB28 Flexible Sprinkler Hose 700 mm to 3700 mm Nominal Assembly Lengths

The Tyco® FASTFLEX is a unique sprinkler drop assembly comprised of the following: branchline adapter nip-ple, stainless steel flexible hose with two slip nuts, sprinkler reducer, and lightweight ceiling bracket compo-nents. (Refer to Figure 1.)
Using FASTFLEX can save time and costs since the system can be in-stalled in false ceilings without cut-ting and threading pipes associated with installing a drop, armover, and el-bows. FASTFLEX makes it possible to test and charge the system with wa-ter before the ceiling grid is installed. Once the ceiling grid is in position, the FASTFLEX hoses can be reshaped to suit the final sprinkler location without draining the system.
FASTFLEX flexible sprinkler hose is installed quickly without large and ex-pensive tools. Ideal projects are of-fices, schools, libraries, hospitals, and shopping complexes. FASTFLEX sprinkler hoses are for use on wet pipe sprinkler systems only.
FASTFLEX offers the following fea-tures:
 Reduced labor costs. Using FAST-FLEX will reduce labor costs by in-creasing efficiency. The installation 
rate is two to three times quick-er when compared to traditional fit-ting methods of installing sprinkler drops.
 Reduced need to recut sprinkler drops. It is not necessary to adjust sprinkler location if ceiling alignment and level are changed. More convenient work flow. UsingFASTFLEX eases bending and ma-neuvering around ducts and trays in congested spaces and for unusu-al ceiling types and curved plaster-board ceilings.
 Construction advantage. Adjust-ments can be made to ceiling levels after installation without impacting sprinklers and drops. Equipment cost savings. Using FASTFLEX reduces cost by elim-inating pipe wastage and reducing the labor associated with cutting, threading, and sealing pipe threads. 
The FASTFLEX flexible sprinkler hos-es described herein must be installed and maintained in compliance with this document and with the applicable standards recognized by the Approval agency, in addition to the standards of any Other authorities having jurisdic-tion. Failure to do so may impair the performance of these devices.
The owner is responsible for maintain-ing their fire protection system and de-vices in proper operating condition. The installing contractor or sprinkler manufacturer should be contacted with any questions.
