Fire suppression Systems

Small-size GFFM Impulse 2-20 series

Small-Size Gas Fire Fighting Modules (Impulse-2, Impulse-20, Impulse-2-Т, Impulse-20-Т) are designed for fire-fighting gas compositions HFC 125, HFC 227ea, FK-5-1-12. It is maximum efficient for fire extinguishment class A (solid substances), B (liquid substances), C (gas substances) fires.

Startup types:

• Automatic startup is activated by electrical impulse from the fire-detecting device to the electromechanical activator;

• Autonomous startup is activated by destruction of the thermally sensitive bottle when temperature exceeds 68ºC.


• service centers and data processing centers;

• storages and depositories;

• mobile communication stations and telecommunications equipment;

• archives;

• gas compressor stations;

• automobile showrooms;

• warehouses with expensive facilities;

• pharmaceutics objects and especially pure manufacturing.


• The wall or ceiling equipment installation allows to use area optimally. For example, equipment can be installed in niches, under floor and false ceiling;

• Module allows completely to use the fire extinguishing agent;

• 2 startup types: automatic (the signal from fire alarm control panel) and autonomous ( thermally sensitive bottle breaks at 68 0C temperature);

• Easy installation and maintenance;

• Minimal start inactivity (less than 1s);

• Dispersion time of extinguishing agent is up to 7 seconds, which allows to create the necessary fire extinguishing concentration in the short term;

• Extinguishing agent is dispersed in all areas of a sprinkler system regardless of the Impulse-2, Impulse-20 installation place.
