At AVION, we have years of experience in Fire Safety Systems. Being the globally active Fire Safety System Integrator, we can provide you with large innovative products, solutions and services.
Fire safety today requires a comprehensive understanding of needs and innovative solutions. As a leading international provider of fire safety technology, we have learned how fires work. This knowledge has contributed to the development of our innovative, high-quality fire safety products, systems, and solutions.
Our unique protection technique ensures.
• Early and reliable fire detection.
• Clear and fast alarming and evacuation processes
• Intelligent extinguishing tailored to the room requirements
All these aspects are at the core of comprehensive fire safety. Only if they are fulfilled can you be assured that people in your building are safe and assets and business processes protected.and exterior electrical System.
One of the oldest & traditional ways of fire protection, which is water based protection system, is in the form of automatic sprinklers. AVION can provide you with complete designing of sprinkler system for any kind of hazard. Our design facility also has the provision for calculation of water demand using latest licensed hydraulic calculation software’s which will accurately determine the water demand as per the standards. Various sprinkler system network designing can be done to cater the specific needs of the customers varying from residential to commercial and industrial.
Wet Pipe: 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.
Dry pipe: 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.
Pre-action: 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.
Deluge and recycling: 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.
Depending on the type of hazard, different varieties and sizes of fire extinguishers are located per standards which form typical manual fire protection systems. Also semi-automatic water based systems are classified as manual fire protection systems. In this case the water under pressure will be available in the pipe line. The valves (normally with 1.5” outlets within the building) have to be opened & hoses pulled down to fight the fire. The landing valves & fire hose cabinets are provided for the use of occupants to fight small fires. Hydrants (normally with 2.5” outlets located outside the building) & fire hose houses are provided for the usage of trained fire fighters. These are the most common but effective systems which we design on daily basis per standards & using hydraulic calculations.
For all water based & foam based, automatic or semi-automatic fire protection systems the water will be available under pressure at all times. This is achieved by providing fire pump set and water tank, all inter connected. Generally there will be an electric motor driven main fire pump, the size (flow & pressure) of which is based on the highest demand from hydraulic calculations. There will be a stand by Diesel engine driven fire pump of same capacity for emergency purpose. Additionally there will be a pressure maintaining device also called as a Jockey pump whose pressure rating will be equal to that of the main pump but with a very low flow rate. Other mandatory accessories will all be fitted together & the inlet connected to a dedicated fire water tank. The capacity of the tank depends on the hazard nature which defines the time period required multiplied with the flow of the main fire water pump. All of these again needs experienced engineers to design an optimum package meeting the standards, yet economically viable. The team at AVION has this in abundance with right tools to execute in a very quick time.
These systems also known as clean agent systems are widely used where the environment needs no tedious cleaning after the extinguishment of fire like computer rooms, control rooms, record rooms, libraries, electrical hazards such as switchgear rooms, substations, battery rooms etc.
Carbon dioxide systems are generally used for unmanned areas since it could be lethal for human beings though it is economical & one of the best agent for extinguishing the fire. Low pressure CO2 systems (360 psi) are used where the quantity of the gas required is high as it is available with tanks from 1 ton to 10 tons& comes with its own refrigeration unit to store CO2 in its liquid form.
High pressure CO2 systems (850 psi) are used where the quantity of gas required is small as they are available in standard bottles of 60, 80 & 120 lbs. capacity wherein the gas is stored under high pressure at normal ambient temperature.
Inergen systems are the evolution of new clean agent systems after the ban on Halon systems. It kills the fire by inerting the hazard with huge quantity of inert gas like Nitrogen. The initial fill & refill of gas is very economical though the storage cylinders & their maintenance might be an expensive affair.
FM200 (trade name) is one of the most successful replacement of Halon systems where it is human friendly & not having the ozone depletion potential. It is stored under pressure of Nitrogen at about 360 psi.
Sapphire/Novec is one of the new replacements for Halon systems which is again human friendly, zero ozone potential & no global warming. Easier to handle as it is in its liquid form at normal ambient temperature & flows easily as compared to FM200.
Designing of above mentioned gaseous fire protection systems needs highly skilled, competent & preferably factory trained personnel as they involve high tech equipment with high pressures & involves flow calculations on special software which are generally provided by the manufacturers. At AVION we have the team with above qualification & who have the experience of designing, erecting & successfully commissioning, hundreds of such systems. We have the necessary software too for running the calculations.
Today the fire alarm system has evolved a long way. Hence the designing of Advanced Intelligent Fire Alarm Systems as per International standards is a challenge which AVION can easily accept & successfully accomplish.
The designing of Fire Alarm System is not only limited to providing a conceptual design, but we also provide actual design drawings which includes Shop Drawings, Installation drawings, Wiring Diagram, Input/output Configuration which will help the installer to install the system accurately. Our design will be customized as per the various manufactures of the systems.
Digital Voice Evacuation is an extension of fire alarm system which is integrated with fire alarm system to provide occupants with digitally prerecorded messages to help them evacuate in case of emergency.
In a huge facility one system may not be sufficient, hence it is required to use many fire alarm systems, all of which can be networked as an integrated system with information available at single window. Our design team of AVION has designed & successfully delivered many such complex projects.
AVION offers designs for Network Integrated Systems using traditional wired technology, Optic fiber technology, IP based Networking using CAT 5 Wire or Wireless technology.
Two Way Communication systems is one of the basic requirements as per Indian Standards to be provided in every Commercial/Residential Buildings. This is to provide communication between occupants and the building security personnel in the event of emergency.
AVION have professionals equipped with design knowledge to design the system as per local norms & international standards.
