HATHEPHS Smoke & CO Detector Combo — 10-Year Battery, Ultra-Thin 4.7 inch Diameter, Easy Install

Overview

The HATHEPHS Smoke Detector CO Detector Combo combines two essential safety devices into one slim package. With dual sensors, it can alert you to both smoke and carbon monoxide, and its audible alarm exceeds 85 dB, designed to capture attention in busy spaces.

Designed for real life, it brings long-term convenience and practical protection to homes, apartments, and vehicles. The device is built around a maintenance-light approach, so you can focus on daily life while staying prepared for unexpected events.

Smart sensing you can rely on

What sets this unit apart is its emphasis on accuracy and speed. Upgraded photoelectric and electrochemical sensors deliver faster responses and fewer nuisance alarms, helping you stay informed without becoming overwhelmed by false alerts. This combination supports timely awareness in the moments that matter most.

Power that lasts, with flexibility

The detector is powered by a sealed 10-year battery, providing long-term, continuous operation with minimal maintenance. A convenient off option helps conserve battery life when the device is not in use, adding a layer of energy management to your safety routine.

Compact design, easy to use

Compact and unobtrusive, the unit measures about 4.7 inches in diameter and 1.1 inches thick. A large top button is simple to reach for testing or silencing, which can be especially helpful for households with children or seniors who may prefer not to climb to reach a switch.
