Back-to-Back 180° Nozzles
1 ft. to 2 ft. apart
Must face away from each other
Nozzles discharge equal quantities

13. ADS / PHX Nozzle Coverage
Tested 46 ft. x 56 ft. Rectangle
Actual coverage area defined as rectangle with diagonal, d
180° - d = 60.5 ft ° - d = 36.2 ft.

14. ADS / PHX Nozzle Height Maximum height for single nozzle is 16 ft.
Nozzle tiers are allowed
Minimum height
1 ft. for UL Listed systems
6” for Kidde Approved
Must reduce coverage area for height, 6” to 12”
30 ft. x 30 ft.
180° - d = 33.5 ft.
360° - d = 21.2 ft.

15. ADS / PHX Nozzle Orientation
Ceiling heights 1 ft. and up, nozzles must be pendant (hanging down)
Ceiling heights less than 1 ft., nozzles may be either pendant or upright
These heights are not UL Listed/FM Approved

Tee Parameters:
Tee Orientation
Flow Splits
Bull Tees
Side Tees
“6 Pipe Diameters”

17. ADS / PHX Piping Network: Tees
Any orientation is allowed
Horizontal and vertical outlets, as well as inlets
1 inlet, 2 outlets

18. ADS / PHX Piping Network: Tees
Bull tee flow split

Maximum imbalance: 85/15 IN
OUT

19. ADS / PHX Piping Network: Tees
Side tee flow split
Minimum imbalance: 65/35
Maximum imbalance
Horizontal feed: 85/15
Vertical feed: 84/16
SIDE OUTLET
(15 to 35) IN
RUN OUTLET
(65 to 85)

20. ADS / PHX Piping Network: Tees
“6 Pipe Diameters” Rule:
Length of pipe between a tee and a change in direction must be equal to 6 times the nominal diameter of the pipe
A change in direction is defined as either an elbow or another tee
Must be adhered to before and after the tee
Only necessary if the tee feeds agent to separate hazards

21. ADS / PHX Piping Network: Layout
Keep network as simple, balanced and short as possible
Consider structural members for hanging/bracing
Avoid obstructions

22. ADS / PHX Piping Network: Layout
Maximum allowable elevation difference in system piping (outlet and furthest horizontal pipe run/nozzle, or nozzles) is 30 ft.
Max. 30’

23. ADS / PHX Piping Network: Layout
Percent of agent in pipe
Max. 140%
Percent of agent before 1st tee
See chart in manual (page 4-6, Figure 4-1)
Arrival time imbalance
Max seconds
Runout time imbalance
Max. 1.0 second
