SERIES AH3, AH3-LP, and AH4 – REGIONAL AVAILABILITY 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
®
submittal 10.54.
• Flexible Hoses are VdS Approved for use in wet systems only.
NOTE
: The VdS Approval applies only for use with specific suspended ceiling systems. Refer to the
“Construction Requirements” section of this handbook. 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.
