FIRE SPRINKLER SYSTEM
Sprinkler systems are among the most useful tools in your firefighting arsenal. Today’s systems have been shown to reduce deaths and property loss by more than 65 percent
The following describes the most common types of sprinkler system.
Since water is always present in the pipes supplying the sprinkler heads, these types of sprinkler system are quick to react upon the operation of a sprinkler head in a fire scenario. These are the most common systems and are used in buildings where there is no risk of freezing. Wet systems are required for multi-storey or high-rise buildings and for life safety systems for UK standards.
The pipes are filled with air under pressure at all times and the water is held back by the control valve outside of the protected area. Should a sprinkler head open in a fire scenario, the drop in air pressure opens the valve and water flows into the pipework and onto the fire. Dry pipe systems are used where wet or alternate systems cannot be used.
Like dry pipe systems the pipes are filled with air but water is only let into the pipes when the detector operates (e.g. smoke detectors). Pre-action systems are used where it is not acceptable to have a sprinkler activate unless there is a real threat of fire, i.e. for high value stock or irreplaceable items, for example, archive material, libraries and computer backup systems.
These are sprinkler systems only used in special cases for industrial risks. They are most commonly used for protecting tank farms where all the sprinkler heads/nozzles operate simultaneously. Foam is often introduced in to the system.
FIRE PUMP SYSTEM
Fire pumps are necessary any time a water supply is not capable of providing the pressure required by the sprinkler system design. Occasionally, there is insufficient city supply or no water supply and the pump must be supplied from a ground storage tank or other static source.
Security Fire has designed, installed and maintained pumps across the country in accordance with NFPA20, the standard for Installation of Stationary Pumps for Fire Protection. We are unique in that we have an on staff fire pump specialist who acts as the manufacturerâ€™s representative during acceptance testing which allows flexibility in scheduling and client peace of mind.
We are regularly involved in the following types of electric and diesel motor driven fire pump assembly installations:
- Split Case Horizontal
- Split Case Vertical
- Vertical In-Line
- Vertical Turbine
- Packaged Skid Mounted
FIRE HYDRANTS SYSTEM
- Fire Hydrants are designed to comply with ANSI/AWWA C502.
- Operation threads are corrosion protected and for effortless operation.
- Fire hydrants are high pressure rated to 250 psi compatible with todayâ€™s trends.
- Internal epoxy paint system gives high corrosion protection to hydrants.
- Advanced safety couplings and flange design reduces traffic damage to hydrant.
- Main valve is easily removed from either the bonnet flange or ground line flange.
- Dry barrel design eliminates damage to the hydrant caused by freezing of the upper part.
- Fire Hydrants are designed for high performance and easy to install, maintain and repair.
- Excellent and proven flow characteristics.
- 2 x 2Â½” NH thread connectors for soft hose connection.
- 1 x 4Â½” NH thread pumper connection for fire trucks.
- 6″ inlet connection complying to mechanical joint ANSI/AWWA C111/A21.11 or flange connection ASME B16.5 Class 150.
FIRE SUPPRESSION SYSTEM
What is FIRE SUPPRESSION Fire Suppression?
FIRE SUPPRESSION fire suppression is also known as HFC227ea. FIRE SUPPRESSION is a waterless fire protection system, it is discharged into the risk within 10 seconds and suppresses the fire immediately.
How safe is FIRE SUPPRESSION?
FIRE SUPPRESSION fire suppression is found as an active compound as a propellant in medical inhalers. This is goes without saying that FIRE SUPPRESSION gas is extremely safe for occupied spaces with the correct fire suppression design.
How does FIRE SUPPRESSION work?
There is a common misconception that FIRE SUPPRESSION gas reduces oxygen this is not true! FIRE SUPPRESSION is a synthetic/chemical fire suppression gas and extinguishes a fire by removing the free radicals or heat elements from the fire triangle. (Oxygen, Heat and Fuel).
The typical concentration of an FIRE SUPPRESSION system is normally between 7.9% to 8.5%. This concentration is determined by the risk that is being protected and by the OEM (Original Equipment Manufacturers) and the ISO14520 standards for fire suppression systems.
What are the advantages of an fire suppression system?
The main advantage of FIRE SUPPRESSION fire suppression, is the small amount of agent required to suppress a fire. This means fewer cylinders, therefore less wasted space for storage of FIRE SUPPRESSION cylinders.
FIRE SUPPRESSION systems reach extinguishing levels in 10 seconds or less, stopping ordinary combustible, electrical, and flammable liquid fires before they cause significant damage. FIRE SUPPRESSION extinguishes the fire quickly, which means less damage, lower repair costs. Like any other fire suppression system, FIRE SUPPRESSION systems are designed with an extra margin of safety for people. Refilling FIRE SUPPRESSION is simple and cost effective, therefore, it also means less downtime and disruption to your business.
FIRE SUPPRESSION is classed as a clean agent which means that it is safe to use within occupied spaces. The safety of FIRE SUPPRESSION fire suppression environments is proven in over a decade of real-world experience and validated by extensive scientific studies. FIRE SUPPRESSION systems take up less storage space than most other fire suppressants.
In addition to the fire protection benefits of using FIRE SUPPRESSION, the environment will benefit as well. FIRE SUPPRESSION fire suppressant does not deplete stratospheric ozone, and has minimal impact on the environment relative to the impact a catastrophic fire would have. FIRE SUPPRESSION fire suppression is a solution that is already working in more than 100 thousand applications, in more than 70 nations around the world.
SMOKE EXTRACTION SYSTEM
FIRE SMOKE EXTRACTION SYSTEMS
When a fire breaks out in a building, whether a residential or an industrial one, it is necessary to extract the smoke in the fire zone in order to evacuate people and possible victims, to protect the building structure and facilitate fire-fighter access.
WE SUPPLY AND MAINTAIN A RANGE OF FIREFIGHTING EQUIPMENT ALL BRITISH STANDARDS BS EN3. DCP FIRE EXTINGUISHER
The Dry Powder fire extinguisher is for fighting class A, B and C class of fire. These can be used to deal with electrical hazards, flammable liquids and gases.
CO2 FIRE EXTINGUISHER
The Co2 fire extinguisher is for fighting class B fires as well as those involving electrical equipment. The non-conductive anti-static horns are suitable for fires involving flammable liquids and electrical hazards. Ideal for office environments with electronic equipment.
FOAM FIRE EXTINGUISHER
The Foam AFFF (aqueous film forming foam) fire extinguisher is for fighting class A and B fires, involving flammable liquids such as petrol or paints. The foam provides a smothering seal over the surface preventing oxygen reaching the fire and so extinguishing it.
WATER FIRE EXTINGUISHER
The Water fire extinguisher is for fighting class A fires, such as with wood, paper and textiles. An economic solution to the most common fire risk.
The wet chemical fire extinguisher is for fighting class F fires which involve cooking oils or fats. The wet chemical works quickly knocking down the flames, cooling the burning oil and chemically reacting to produce a soap-like solution which then seals the surface to prevent any re-ignition.
