Fire defense and firefighting houses system ISAS-F

This system ISAS-F is designed for protection houses from forest fire and emergency extinguishing houses using a technology spraying mixture wetting agent\water. Neutral gas generators are used to create the effect of fine water and water mist.

The system consists of special tanks (ISAS module) which contain witting agent\water mixture and built-in neutral gas generators.

Spraying is carried out through pulverization system installed on the roof and possibility around hose.

ISAS module can be located in any place or can be completely hidden underground for safe free space inner and around the house. The location of the module does not affect its work.

ISAS module can operate in two modes:

Protection house mode, wetting agent mix consumption rate is up 2 to 20 liters per second

Fire extinguishing mode, water consumption rate up to 50 liters per second.

ISAS-F system has no electric valves and other electrical actuators. It is completely independent on external power sources and eliminates the possibility of failure of mechanisms that are bound to external electrical interference as a result of any outer accident.

The equipment designed and furnished shall be of a type and quality acceptable to the owner and local Fire Authorities.

ISAS-F system is guaranteed to execute: Start water feed in a fire extinguishing mode not exceeding the timeframe of

three seconds after the fire source determination in an automatic mode or remote or manual start-up.

Execute fire extinguishing or emergency cooling at any time during 10 years the least at the absence of external sources of electricity and water.

Perform its work in case of global disaster or accident electrical network with a large number of electrical interference.

The principles of the system operation.

The launch of the ISAS-F system in the automatic mode is conducted by sending a low power electrical signal or manually by pressing a button or pulling the operation ring or from remote radio (or from internet) signal. In the independent automatic mode the signal to start the system is sent by special full autonomous thermal sensors that automatically generate an electrical signal. Sensors are 100% independent from external sources of electricity. The sensor is completely protected from external electrical noise.

Remote manual start is also possible.

After starting the pressure generator, neutral gas (fire aerosol) is supplied into the module case and this starts the displacement of wetting agent\water mix into sprays or into the water pipes.

The capacity of gas and pressure in the housing is automatically maintained at the same level regardless of the amount of displaced water.

For emergency pressure release, each ISAS module contains pressure release valves.

The pressure level in the system during operation shall be determined during the module charging procedure with pressure generators and can be any in the range from 0.2 to 2 Mpa.

After starting the module all mix is displaced and pressure generator resource is completely consumed. Recharging the module is conducted by trained personnel it takes less than one hour.

Constantly maintained pressure of the neutral gas allows the creation of highly effective thin streams mix wetting agent\water (fire extinguishing mode) or mix mist (protection mode).
