NOTES:
1. A dry system is used to facilitate seasonal shut down of the house.
Consequently an air temperature of 0°F was used for this example.
2. Horizontal Sidewall Sprinklers are used to allow the system to com-
pletely drain.
3. The Model RCP-1 Panel outlet flow is based on the least available
water flow to hydraulically support the two most remote sprinklers at
16 GPM each.
4. Water delivery to the most remote sprinkler is calculated assuming the
highest possible initial air pressure based on a 10 to 14 psi automatic
air supply.
5. This example is for reference only. Volumes and delivery times vary
depending on the size of the living space and system piping layout
and design, as well as available water supply. Designers should reflect
system layout and available water supply as accurately as possible for
determining water delivery times.
