Table

20. Calculate Volume Dimensions taken during hazard analysis
OK to subtract permanent volume reductions
Columns
Platforms
Do NOT subtract for equipment and moveable objects!

21. Design Temperature
To calculate agent quantity, use minimum expected ambient temperature
Agent concentration is proportional to air temperature
Same quantity of agent will result in a low concentration at low temperatures and a high concentration at high temperatures

22. MDQ Calculation Example
Enclosure is 10 ft. W x 10 ft. L x 10 ft. H
Min Ambient Temperature = 70°F
Class A Surface Fire Hazard

23. MDQ Calculation Example
Volume = ft.3 s = ( x 70°F) =
W = (1000 ft.3 / ) x (4.2% / 100% - 4.2%) = 37.9 lb.
- or -
Flooding Factor
(4.2%, 70°F) = lb./ft.3
W = ft.3 x lb./ft. 3 = 37.9 lb.

24. EXAMPLE PROBLEMS

25. Correct For Pressure Differentials
Must correct if ±11% or more from normal barometric pressure at sea level
Approximately ± 3000 feet from sea level
Reference Table in NFPA (also in manual)
Atmospheric correction

Highly depressurized; keep particles in

26. EXAMPLE PROBLEMS

36. Novec 1230™ SERIES SYSTEMS

37. NOVEC 1230 Nozzles Two nozzle types Nozzle sizes
3/8” through 2”
1/4” offered - Non UL and FM
All nozzles must be pendant (hanging down)

38. NOVEC 1230 Nozzles 180° Nozzle Placed 6” ± 2” from a wall
Orifices aimed away from the wall
6 - 19” ± 2” from ceiling to orifices
As close to center of the wall as possible
At least 1/3
No corner placement

39. NOVEC 1230 Nozzles 360° Nozzle Discharges agent in a 360° pattern
Placed as close to center of hazard as possible
6” to 19” from ceiling to orifices

40. Novec 1230 Discharge Discharged as both liquid and vapor
When near obstructions, liquid will “splash”
Will effect the mixing of agent in the space due to reduced momentum in discharge.

41. NOVEC 1230 Nozzle Locations
Proximity of nozzles to significant obstructions
6 ft. of clearance between nozzle and wall (or significant obstruction)
Additional agent can be discharged to compensate for “losses” on obstructions

42. NOVEC 1230 Nozzle Locations
Proximity of multiple nozzles
At least 10 ft. of clearance between nozzles

43. NOVEC 1230 Nozzle Locations
Back-to-Back 180° Nozzles
1 ft. to 2 ft. apart
Must face away from each other
Nozzles discharge equal quantities

44. NOVEC 1230 Nozzle Locations
For smaller enclosures
Recommend using 180 nozzles in order to meet 6 ft. clearance
Recommend placing 180 nozzles along longest wall to allow maximum clearance in all directions

45. NOVEC 1230 Nozzle Coverage Tested 35.6 ft. x 35.6 ft. Rectangle
(10.9 m x 10.9m)
Actual coverage area defined as rectangle with diagonal, d
180°-d = 39.8 ft.(12.1m) °–d = 25.2 ft.(7.7 m)

46. NOVEC 1230 Nozzle Height Maximum height for single nozzle is 16 ft.
Minimum height
1 ft. for UL Listed systems

47. Nozzle Tiering
Use two rows of nozzles to protect enclosures greater than 16 ft. high (note max elevation difference limit)
Max 16’
Max 16’

48. Quantity of Nozzles Not always dictated by coverage area
Coverage volume 35.6 ft. x 35.6 ft. x 12 ft. requires 574 lb. of Novec 1230
Will not discharge out of a single nozzle within 10 seconds!
Rule of Thumb:
Approximately 200 lb. per nozzle

65. Hints, Tips and Other Considerations

66. Multiple Systems / Single Hazard
If enclosure is large, consider using:
Multiple, modular NOVEC 1230 systems, which will discharge simultaneously, located throughout the hazard
However - With 100% Agent in Pipe limit - Novec flows well in complex pipe networks.

67. Single System / Multiple Hazards
If protecting more than four enclosures that are not connected, consider:
Separate NOVEC 1230 systems

68. Agent Migration
If protecting a single space with multiple nozzles, each nozzle should discharge the quantity of agent required by the nozzle’s design coverage area
Maximum of 5% of the required agent may be discharged by a nozzle protecting an adjacent area

69. Designing for Multiple Hazards
For more than one hazard, design with an adjusted concentration of 4.2% or higher
Extra agent will make flow splits a lot easier
NOTE: Still use 4.2% as minimum

70. Tee Design Factor NFPA 2001 5-5.3.1 Starting from each hazard, count:
Every tee within the hazard that splits to a separate hazard
Each tee between entry point to hazard and the agent source (not including tees in a manifold)
Reference Table in NFPA 2001 for additional agent required

71. Tee Design Factor Example

72. Tee Design Factor Example
Maximum tee count is 6
From NFPA 2001, Table , a tee count of 6 requires a 0.02 (2%) safety factor
