Notes:
1. The combined total linear pipe (supply, overlapping branches, and ADP nozzle branches) must not
exceed 70'.
2. Max Supply Line Pipe can be increased from the values above if the total combined overlapping and
ADP branches are reduced by a corresponding amount.
3. Individual branch limitations must be maintained per the UL/ULC listed limits (e.g., max 5’ pipe & max
3 elbows for a dedicated ADP nozzle branch).
4. The notes from the UL/ULC listed dual cylinder piping table must be followed (e.g., vertical rise, splash
requirements).
5. Duct or plenum branches may be substituted for dedicated ADP appliance branches per the above
table, provided the individual branch limitations are maintained per the UL/ULC listed limits (e.g.,
max 3’ pipe & max 2 elbows for an individual duct/plenum branch).
6. The R nozzle provides a wider spray angle than the ADP nozzle, the nozzles are identical in flow
points and flow rate. Therefore, the R nozzle may be used as a substitute for the ADP nozzle for low-
proximity range protection.
