Deluge Sprinkler System

In the deluge system, all sprinklers are open and normally there is no water in the piping. When fire occurs, a supplementary detection system senses the fire and automatically
opens a water control valve. This allows water to flow through the piping system to all sprinklers.


Deluge System

Preaction Sprinkler System

In a preaction system, all sprinklers are closed and normally there is no water in the piping. A preaction system is used when faster response is desired (versus a dry pipe system). When fire occurs, a supplementary detection system (more sensitive than the sprinkler elements) senses the fire and automatically opens a water control valve which
allows water to flow into the piping system. Subsequent water discharge occurs from individual sprinklers as they respond to the heat of the fire. The system shown below uses HAD’s (Heat Actuated Detectors) and a dropweight release to open the preaction valve. Alternate detection systems can also be used. Pre-priming foam solution is not needed as foam will be proportioned into the piping during operation.

PreAction System

Dry Pipe Sprinkler System

Dry pipe systems use automatic sprinklers that are attached to a piping system containing air under pressure. When the air is released from the opening of the sprinklers, the water pressure overcomes the lessened air pressure and opens the dry pipe valve. The dry pipe valve is designed so that a moderate air pressure prevents a higher water pressure from opening the valve.

Once the valve is opened, the water flows into the piping system and out the opened sprinklers. This system provides protection in areas subject to below freezing temperatures. Piping must be drained of water or foam solution following operation to prevent freezing.

Typically, upright sprinklers are used to allow drainage.  Otherwise, approved dry pendent sprinklers must be used to prevent freezing. Dry pipe systems are inherently slower in operating and should be considered less desirable for applications using AFFF.


Dry Pipe System

Wet Pipe Sprinkler System

This system uses automatic closed-head sprinklers that are attached to a piping system containing water. Water discharges immediately from those sprinklers opened by a fire. A flow of water through the valve sounds an alarm.

Wet pipe systems should not be used where freezing conditions are likely to damage piping. In systems using AFFF concentrate, the piping to the sprinkler heads can be pre-primed with foam solution to enable immediate effective foam discharge. AFFF solution in contact with steel pipe may gradually lose its fire effectiveness. Samples of this solution should be checked on an annual basis and replenished as needed. A test discharge connection is recommended downstream from the proportioner and should be located to fill a maximum portion of the sprinkler system piping. The test connection should be of sufficient size to meet the minimum flow rate for the particular proportioner. This type of system is the most reliable, simplest, and fastest responding of all closed-head sprinkler systems. Conversions of water systems to foam can usually be accomplished easily. (Local codes and regulations should be investigated prior to conversion.)

Wet Sprinkler System

Foam Water Sprinkler System

An automatic sprinkler system is designed to distribute water or foam solution to a specific hazard area. The application rate, commonly referred to as ‘‘ density,’’ is frequently expressed in units of gallons per minute per square foot ( gpm/ ft2) or liters per minute per square meter (Lpm/m2) of area.

The worst potential fire situation is generally used to determine the number of sprinkler heads discharging. This, in turn, determines the water supply demand; and in the case
of foam sprinkler systems, the required amount of foam liquid concentrate. Characteristics of some flammable products may require higher densities and special foam liquid

Areas protected by sprinkler systems are usually given a class of occupancy (light, ordinary, or high hazard). The class of occupancy relates to the probable number of sprinkler
heads that may operate in a particular fire situation and governs the maximum spacing allowed between sprinkler heads. The sprinkler head provides for a nearly uniform distribution of water or expanded foam over a given area. The solution strikes a deflector and is broken into a circular pattern of distribution. Spacing of sprinkler heads results in overlapping patterns to ensure uniform coverage and effective fire control.

Pipe sizing to the sprinkler heads is commonly determined by hydraulic calculations to assure an adequate supply of water and uniform distribution from the sprinkler heads. The standard addressing sprinkler system design is NFPA Standard 13 or BS EN12845. Additional guidance for foam systems design is contained within NFPA Standards 11, 16, and 30.

Types of Sprinkler Head

Conventional sprinkler heads

sprinklers Conventional sprinklers heads are available for either upright or pendent installation. A heat sensitive element, consisting of either a fusible link or frangible glass bulb, is rated for a specific operating temperature. A standard orifice sprinkler is 15mm; however, various small and large orifice sprinklers are available to achieve the desired density with the available water supply pressure.

Conventional open sprinkler heads, without the heat-sensitive element, are used for total area flooding “deluge” systems. In applications using AFFF concentrates, the conventional sprinkler is acceptable. The UL listing directory should be consulted to ensure the sprinkler head is listed with the manufacturer’s foam concentrate.
Acceptable foam quality is expected from conventional sprinkler heads of similar design to those listed. These sprinklers cannot be used with protein or fluoroprotein base foam concentrates which require air aspirated discharge devices.

Foam/water sprinkler heads

sprinklers Foam/water sprinkler heads are open type and generate air aspirated foam by drawing air into the foam solution stream. The sprinkler head is available for either
upright or pendent mounting and may be used with either foam or water. Patterns of coverage are similar to conventional sprinkler heads; however, only a 3/8 in. orifice is
available corresponding to a K-Factor of 3.0.




Types of Sprinkler Systems

Sprinkler systems can be either closed-head or open-head (deluge) systems using conventional sprinkler heads. Sprinkler systems using foam/water sprinkler heads can
only be open-head systems as these sprinklers are not available with heat-sensitive elements. Closed-head sprinkler systems can be of three different types: wet pipe, dry pipe, or preaction. An AFFF foam can be used in any closed-head sprinkler system as covered by NFPA Standard 16 – Foam/ Water Sprinkler Systems.

New Range of Monitors

Posted on April 10th, 2011

MonitorTyco Safety Products Fire Suppression Group has unveiled a number of groundbreaking pieces of SKUM™ brand foam hardware: the new remotely controllable FJM-EL fog / jet monitor range, and the new HG high-expansion foam generators.

They join a line-up of dependable and efficient foam fire protection solutions that are globally favoured for high value, high risk petrochemical, aviation, marine and power plant applications.

The new FJM-EL monitors are powerful additions to the established SKUM FJM range. All three models – the FJM-100 EL, the FJM-150 EL, and the FJM-200 EL – offer exceptional flow performance, incorporate electric motor driven elevation and rotation and solenoid valve operated fog / jet pattern adjustment.

However, it is the FJM-EL’s remote control operation that really sets them apart as fix-mounted monitors designed for the safe delivery of foam or water, either as a solid jet or a fog pattern.

Foam Shelf Life

Posted on April 15th, 2011

Depending on what type of foam concentrate you have, the typical shelf life will vary.Protein type concentrates have a shelf life of about 7 to 10 years.

The synthetic type concentrates, which are the AFFF, ARC type AFFF, Class “A” and High-Expansion concentrates, have a shelf lives of 20 to 25 years.

Bladder Tanks

Posted on April 15th, 2011


Bladder Tanks are the most common type of balanced pressure proportioning systems.  The system uses a pressure rated tank with an internal rubber bladder.  The foam concentrate is stored within the bladder and system water pressure is used to squeeze the bladder and provide pressurised concentrate to the proportioner.

Bladder tanks come in a wide range of sizes from 300 us gallons to 3000 usgal in the Ansul Product Range and from 400 litres to 25000 litres in the SKUM range.Bladder Tanks provide a self contained balanced pressure proportioning system requiring no external power or foam pumping.

Recent developments by SKUM have enhanced the advantages of using a bladder tank as the means of providing a balanced pressure proportioning system – see News items for details

New Developments in Bladder Tanks

VertBladTnkInstalIn the past there have been two problems associated with bladder tanks – the possibility of the bladder rupturing and also the inability to refill the unit during operation because it is pressurised.

Both of these problems have now been tackled and resolved by SKUM.

Unique fixing and support methods now employed by SKUM now ensure the integrity of the bladder while still maintaining the ease of bladder installation and operation.

The problem of refilling during operation has also been overcome by providing a pressurised source of foam concentrate from a mobile unit as an optional extra to the basic tank supply.  The optional mobile unit also provides a simple means of refilling after operation.

The list of advantages for bladder tank usage has now been re-written as follows:-

  • Few moving parts
  • Low Pressure Drop
  • Variable Flow capability
  • Can be used with all types of foam concentrate
  • No external power source required
  • Can be refilled during operation
  • Can easily be used in automatic systems
  • Can meet the requirements of all internationally recognised design codes
