👉 The alarm for "fumes" typically indicates the presence of hazardous gases or vapors in the air, which can be extremely dangerous to health and safety. These fumes often originate from industrial processes, chemical spills, or fires, and can cause respiratory issues, headaches, dizziness, and even long-term damage if inhaled continuously. The alarm system is designed to detect these toxic substances and immediately alert occupants through visual signals (like flashing lights) and auditory warnings (such as sirens or alarm sounds), prompting them to evacuate the area and seek fresh air or medical attention if necessary. It's a critical safety measure to prevent exposure and mitigate potential hazards.
