SprinkCALC™ - Fire Sprinkler Calculation Software


2/4

Calculation engine for SprinkCAD™

or a Standalone application.

• Multiple measurement settings includingmetric/imperial, Hazen-Williams/Darcy-Weisbach,

demand/ supply.

• Calculations can be created for differentcodes and standards: NFPA13, EN12845,

AS2118.1, NZS4541 or custom settings.

• Calculate anything from simple ‘tree systems’to multi level ‘looped dry systems’.

• Output reports can be customer defined.

• Can be used as a standalone application.

• Send files electronically and let the AHJ reviewthe calculation using the free SprinkCALC

Viewer.

First major advancement in fire protection

technology for dry pipe systems in 30 years.

• Calculate the time taken to trip a dry valveand deliver water to open sprinkler(s).

• Tried and tested accuracy.

• Calculate the hydraulic demand and thedelivery time without leaving the program.

• First UL Listed program of this type asdefined by NFPA 13, chapter 7.2.3.6.

• Send files electronically and let the AHJ reviewthe calculation using the free SprinkCALC

Viewer.

Forget your old way of working, SprinkFDT™ (Fluid Delivery Time)

is designed for easy use and simple operation. It empowers design

professionals to accurately predict the time it takes to trip a dry valve and

deliver water to the remote sprinkler(s) without the requirement of a

physical trip test.

SprinkFDT™

saves you time and money

• Fluid Delivery Time

calculation: 45 seconds.

• Result is acceptable.

7. The same design but now

calculated with the use of

an electric accelerator.

This accelerator has a fixed

release time of 4 seconds.

• Air pressure in the

system: 2.1 bar (enough

to keep the valve

closed).

• Electric accelerator

(fixed release of 4

seconds).

• Fluid Delivery Time

calculation:

33 seconds.

• Result is acceptable.

Conclusion/Results:

• FDT calculations proves that

a single dry pipe valve can

supply a system with a

volume of 7,883 litres.

• According to table 18 of the

EN12845 this system

should be supplied with 3

dry pipe valves.

• The SprinkFDT™ calculation

saves the installation costs

of 2 dry alarm valves, 2

shut off valves and feedconnections.

• Only a single Inspection

Test Connection is required

instead of the original 3

connections.

• Only 1 air maintenance

device is now required

instead of the original 3

products.

• With the installation of an

electric accelerator the Fluid

Delivery Time can be

reduced even more.

SprinkFDT™ saves

you time and money

• Save costs on labour

and materials during

installation.

• Save time required for

testing and inspecting

the system.

• Save on resources

required for systemmaintenance.

Case Study ExampleFeatures & Benefits:• Calculates the time it takes to trip a dry valve

and deliver water to the open sprinkler(s) with

the accuracy of a physical trip test, but without

the cost.

• Enables the user to spot problems at thedesign stage, and find solutions before

installation begins.

• Takes advantage of the maximum volumes foreach alarm valve, saving the cost of up to 3

alarm valves with all associated risers and

distribution lines.

• Cost of labour required for testing andmaintenance reduced as the number of

systems required is decreased.

Standards requirement fluid delivery time andvolumes for dry systems

EN12845:

• The net volume of the pipe work downstream of the controlvalve set shall not exceed that shown in Table 18, unless a

calculation and test shows that the maximum time between a

sprinkler opening and water discharging is less than 60 seconds.

NFPA 13:

• System size shall be such that initial water is discharged fromthe system test connection in no more than

60 seconds.

• A system size of no more than 500 gal (1893 L) shall bepermitted without a quick opening device.

• A system size of no more than 750 gal (2839 L) shall bepermitted with a quick opening device.

• System size shall be based on dry systems being calculatedfor water delivery in accordance with 7.2.3.6.

Design parameters:

• Standard: EN12845.

• Hazard class: HHS.• Required density:

12.5mm/min.

• Area of operation: 325m2.

Design step by step:

1. Design the system

• Total area: 90 x 80 =

7200m2.

• Distance between

sprinklers: 3m.

• Distance between

branch lines: 2.5m.• Area per sprinkler:

7.5m2.

• Number of sprinklers:

960 pieces.

2. Determine the pipe

diameters

• Main: DN150.

• Branch line: DN50.

• Dry pipe valve: DN150.

3. Calculate the remote area

• Remote area: 325m2.

• Simulate 44 sprinklers

open.

• Sprinkler k factor: k =

115.

• Hydraulic result: 5.56

bar @ 4841 lpm.

4. If necessary adjust the

diameters of the system

and recalculate.

5. Select a suitable pump.

6. Calculate the Fluid

Delivery Time for the

most demanding sprinkler

• Air pressure in thesystem:

2.1 bar (enough to

keep the valve closed).

• Mechanical accelerator.
