* SERIES AH3 AND AH4 – REGIONAL AVAILABILITY ONLY
Series AH1, AH1-CC, AH2, AH2-CC, AH3, and AH4 Flexible Hoses are VdS Approved for use in wet systems only.
Only VdS Approved pendent spray sprinklers of 10-mm, 15-mm, and 20-mm nominal diameters with K-factors of 57, 80, and 115 shall be used.
Tested with a 5 3/4-inch/146-mm length straight reducer.
When using a No. 101 90° Elbow or a No. 102 Straight Tee in place of a Style 108 Coupling on the end of a Series AH1-CC or AH2-CC Flexible Hose, the friction loss data
shown above shall be added to the No. 101 or No. 102 friction loss data published in Victaulic publication 10.54.
The VdS Approval applies only for use with the following manufacturers’ suspended ceiling systems:
Ceiling Suspension Systems for Styles AB1, AB2, and AB10 Brackets
AMF
Armstrong
Chicago Metallic
Dipling
Durlum
Geipel
Gema-Armstrong
Hilti
Knauf
Lafarge
Lindner
Odenwald
Richter
Rigips
Rockfon Pagos
Suckow & Fischer
USG Donn
Other manufacturers’ ceiling systems, with comparable or better performance, can be considered for approval. VdS standards for safety include, but are not limited to:
pressure cycling, corrosion resistance, flow characteristics, vibration resistance, leakage, mechanical strength, and hydrostatic strength. Differences in equivalent lengths
are due to varying test methods, per FM 1637 and VdS standards. Refer to these standards for additional information regarding friction loss test methods.
