2. Informació de seguretat
Your safety is paramount. This detector is a crucial safety device, but it is not a substitute for proper maintenance of fuel-burning appliances or ventilation systems. Always follow local regulations and guidelines for detector placement and maintenance.
2.1. Understanding Hazards
- Perill de monòxid de carboni (CO): Carbon monoxide is a colorless, odorless, and toxic gas. Mild poisoning symptoms include headaches, dizziness, palpitations, nausea, vomiting, limb weakness, and brief fainting. Higher concentrations can lead to coma, collapse, and even death.
- Combustible Gas Hazard: Natural gas is a colorless, odorless, non-toxic, and non-corrosive gas. Methane, a primary component, can cause suffocation at high concentrations. Gas leaks can also produce toxic carbon monoxide if combustion is incomplete.
- Smoke Hazard: Thick smoke contains harmful particles and gases (e.g., carbon monoxide, sulfur dioxide, nitrogen oxides). Inhaling smoke during a fire can irritate respiratory passages, cause coughing, chest tightness, and shortness of breath, potentially leading to damage to the nervous and cardiovascular systems.
2.2. Importants precaucions de seguretat
- Do not paint the detector. Paint can clog the sensor openings and interfere with proper operation.
- Do not block the air intake vents on the device.
- Test the detector regularly as described in this manual.
- Do not use cleaning agents or solvents on the detector.
- Ensure the device is plugged into a functional power outlet.

Placement Guide: For optimal safety, it is crucial to strategically place detectors. Refer to the diagram above for recommended installation points in various areas of your home, such as bedrooms, dining rooms, kitchens, living rooms, basements, and garages.
