Sprinkler Distribution Patterns
The distribution patterns presented on the following pages are provided to illustrate
the approximate water spray trajectories for various Reliable sprinklers at pressures of
7, 15 and 30 psi, unless otherwise noted. However, it must be emphasized that
Reliable sprinklers must be installed according to the pertinent National and Local Fire
Codes, Standards and Installation Rules, all of which are considered to be minimum
requirements for sprinkler system installations. If Reliable's sprinklers are not
installed accordingly, the listing, approvals and warranties are not valid.
The minimum requirements for water distribution from sprinklers (i.e., densities, areas
of coverage, horizontal and vertical obstructions) are primarily provided in National
Standards. These are the requirements that must be satisfied when designing sprinkler
placements; whereas, the following distribution profile patterns are only for information.
