About This 3-Packs Advanced 4-in-1 Detector: This advanced Natural Gas and Carbon Monoxide Detector combines sensors for natural gas, carbon monoxide, temperature, and humidity. Equipped with robust features, dual sensors, a dual alarm system, and swift responsiveness, it ensures all-around protection to safeguard your home. Rapid Alert with Dual Warning System: This RV carbon monoxide detector features both visual and audible alarms. When hazardous gas levels are detected (CO ≥ 150 PPM, natural gas ≥ 5% LEL), a flashing red light and a powerful alarm (≥ 85 dB) activate simultaneously. This prompt warning allows you and your family to identify dangers quickly, offering vital safety protection. Energy-Efficient & Eco-Friendly Design: This carbon monoxide detector plugs directly into an AC 110V~220V outlet, with a low static power consumption of 2W for enhanced energy savings. Featuring a long-lasting electronic sensor, it is both environmentally friendly and durable, eliminating the need for frequent replacements. LCD Screen & Multi-Purpose Design: This RV carbon monoxide and propane detector comes with a vibrant LCD color display, providing accurate readings for carbon monoxide (0-2000 PPM) and natural gas (0-10% LEL). Its space-saving design makes it perfect for use in homes, hotels, RVs, and cruise ships. Note Before Use: Please tear off the protective film before use. After insertion, you need to wait for 180 seconds for the detector to adapt to the environment. Press the self-test button and the alarm will sound. In addition, because heat will be generated after power is turned on, you can wait for 30 minutes, and the humidity and temperature values will be more accurate.
