Gas Leak Smell Alarm Device

Gas-based fire extinguishing system warns dangerous situations with warning lights and sirens, but it still leads to human accidents workers who are repeatedly exposed to alarm signals due to ambient noise and malfunctions often fail to recognize the alarm signal.

In order to prevent human injury due to such situations, the gas release olfaction alarm system is a device for evacuating all the gas emission to the target area and evacuating workers who perceive the risk by visual / auditory olfactory evacuation from the target area. This is a system that dramatically improves the problems of existing alarm devices.


  • Warning system before fire extinguishing facility release via visual, auditory and smell (olfactory)
  • Prevent gas poisoning / suffocation
  • Use of highly viscous additives
