FIRE Sprinklers Distribution in water suppression system** :From **NFPA** tables according to hazard We get four important notes which used in our design. Maximum and Minimum spacing between two **Fire Sprinkler**,Maximum and Minimum spacing between sprinkler and wall.

Sprinklers Distribution in water suppression system |

## Sprinkler Distribution in water suppression system

** Notes & Design in a zone:**

**NFPA Codes :**

- Maximum space between 2
**FIRE Sprinklers**= 4.6m - Minimum Space between 2
**FIRE Sprinklers**= 1.8m - Maximum Space for Wall and
**FIRE Sprinkler**= 2.3m - Minimum Space for Wall and
**FIRE Sprinkler**10.2cm

** 2. Second Step :**

we use the following 3 rules :

- Length / 4.6
- Width / 4.6
- follow this distribution : x 2x y 2y
- x : location between wall and Sprinkler
- 2x : location between 2 sprinklers

3. sum the values of x and y and solve for x and y such that

- sum x = Length of Zone
- sum y = Width of Zone

4. distribute distance of

**Fire sprinklers**according to values of x and yExample :

Room ( 10m x 5m ) and i want distribute sprinklers for it ?

### 1 . Step apply rule :

Length / 4.6 = 10/ 4.6 = 2.20 ( 3 by round)

this means i draw 3 Horizantal lines in zone relative to Length

Width/ 4.6 = 5m/ 4.6 = 1.1 ( 2 by round)

this means i draw 2 Vertical lines relative to width.

### 2. .Apply Distribution( look at figure)

3. Apply second rule :

sum x = L

sum y = W

using design we have :

x+2x+2x+x = 10

6x = 10

x= 1.6m

this means

Distance between Sprinklers and wall = 1.6m

Distance between 2 Sprinklers = 3.2m

Similarly for Y :

4y=5

y = 1.25m

this means

Distance between sprinkler and wall (vertical) =1.25m

Distance between 2 sprinklers = 2.5m
