1. Introduction
The Kidde Nighthawk Carbon Monoxide Alarm, Model KN-COPP-B-LP, is designed to detect carbon monoxide (CO) gas and alert occupants to its presence. This battery-operated unit features a digital display for real-time CO level readings and provides continuous protection, even during power outages. This manual provides instructions for proper installation, operation, and maintenance to ensure optimal performance and safety.
2. Informations importantes sur la sécurité
Carbon monoxide (CO) is an invisible, odorless, and tasteless gas that can be fatal. It is produced when fuels burn incompletely. Sources can include furnaces, water heaters, fireplaces, gas stoves, and vehicle exhaust. Proper placement and regular testing of your CO alarm are crucial for your safety.
- N’ignorez jamais une alarme de CO. Act immediately if the alarm sounds.
- Know the symptoms of CO poisoning: headache, dizziness, nausea, vomiting, confusion, and flu-like symptoms.
- Assurer une ventilation adéquate for fuel-burning appliances.
- Ne peignez pas l'alarme. Paint can clog the openings and interfere with the sensor.
