Why do we need the ADS / PHX Series?

•Longer Pipe Runs

•Convenient Cylinder Placement

•More Efficient Use of Cylinder Fills

•Difficult Pipe Networks

•Greater Flexibility

•Smaller Diameter Pipe

ADS / PHX Nozzles

•Two nozzle types– 180° Nozzle– 360° Nozzle

ADS / PHX Nozzles

•180° Nozzle– Placed 1” to 2” from a wall

– discharge slot aimed away from the wall– As close to center of the wall as possible

– At least 1/3– 1/2” to 6” from ceiling to discharge slot

ADS / PHX Nozzles

•360° Nozzle– Placed as close to center of hazard as

possible– 1/2” to 6” from ceiling to discharge slot

ADS / PHX Nozzle Locations

•Proximity of nozzles to significant obstructions– At least 3 ft. to 4 ft. of clearance

between nozzle and wall (or significant obstruction)

•Proximity of multiple nozzles– At least 6 ft. of clearance between

nozzles

2' (Min 1')

ADS / PHX Nozzle Locations

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

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. 360° - d = 36.2

ft.

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.

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

ADS / PHX Piping Network: Tees

•Tee Parameters:– Tee Orientation– Flow Splits

– Bull Tees– Side Tees

– “6 Pipe Diameters”

ADS / PHX Piping Network: Tees

•Any orientation is allowed– Horizontal and vertical outlets, as well

as inlets

•1 inlet, 2 outlets

IN

OUT OUT

ADS / PHX Piping Network: Tees

•Bull tee flow split– Minimum imbalance: 50/50– Maximum imbalance: 85/15

SIDE OUTLET(15 to 35)

IN RUN OUTLET(65 to 85)

ADS / PHX Piping Network: Tees

•Side tee flow split– Minimum imbalance: 65/35– Maximum imbalance

– Horizontal feed: 85/15– Vertical feed: 84/16

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

ADS / PHX Piping Network: Layout

•Keep network as simple, balanced and short as possible

•Consider structural members for hanging/bracing

•Avoid obstructions

Max. 30’

ADS / PHX Piping Network: Layout

•Maximum allowable elevation difference in system piping (outlet and furthest horizontal pipe run/nozzle, or nozzles) is 30 ft.

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. 0.74 seconds

•Runout time imbalance– Max. 1.0 second

ADS / PHX Piping Network: Pipe Sizes

•Pipe sizes 1/2” through 6” are Listed/Approved– Largest nozzle size is 2”

ADS / PHX Piping Network: Nozzles

•Minimum nozzle pressure: 72 psi

ADS / PHX Piping Network: Hydraulic Calculation

•Enter:– Enclosure info– Agent quantity– Agent Source– Pipe network

•Run main calculations

•Verify system acceptance
