Fire detection and alarm systems, namely, fire alarms, detectors for early fire detection in the nature of smoke detectors, fire extinguishers, fire sensors, gas detectors, gas concentration sensors, smoke alarms; preventative and suppressive fire prevention and fire extinguishing systems, namely, inerting or inert-gas protection and shielding systems for preventing and extinguishing fires comprised of smoke, fire and gas detectors for early fire detection, gas concentration sensors, and metal or non-metal inert gas reservoirs; programmable electronic controls for fire alarms, fire detectors, gas detectors, smoke detectors, and fire and gas sensors; software for use in dimensioning and designing the proper layout of fire and gas detection alarm systems

Apparatus for ventilation, namely, air and gas supply systems comprised of ventilators for automatically introducing indoor air or the air used to cool down electronic apparatus into plastic or metal pipes used in the before-mentioned systems and metal or non-metal inert gas reservoirs; ventilators for commercial use in the before-mentioned systems; air and gas separation apparatus for the production of inert gas out of the environmental or pressurized air comprised of technical filters for pre-cleaning the supplied air, membranes mainly consisting of hollow fibers for causing the natural components of said air to diffuse through said hollow fiber membrane at different speeds and volumes
