HATHEPHS Combination Smoke & CO Detector Alarm — 10-Year Battery, Dual Sensor, Large Test Button (3-Pack)

Two-in-One protection for safer spaces

The HATHEPHS Combination Smoke and Carbon Monoxide Detector Alarm combines two essential sensors into a single compact unit. When it detects smoke or elevated carbon monoxide levels, a powerful alarm (over 85 dB) sounds to alert everyone nearby. This dual-detection approach is designed for homes, apartments, or RVs, helping you stay aware in common living areas from bedrooms to hallways, kitchens to entryways.

• The built-in sealed lithium battery provides up to 10 years of continuous power, reducing the need for frequent replacements.
• There is an option to turn it off when not in use to conserve battery life, making it adaptable for seasonal spaces or mobile setups.

S sensitivity you can rely on

With upgraded photoelectric and electrochemical sensors, the detector aims for faster responses and fewer nuisance alerts, helping you respond to genuine risks with confidence.

• Faster detection improves awareness during real-world events
• Reduced false alarms minimize interruptions in daily life
