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.

• 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.
