    Have you taken any measures to protect yourself in case of fire or carbon monoxide poisoning? In fact, most people don’t take adequate precautions. This jeopardizes their health and safety.

    Keep your family safe with this smoke and carbon monoxide alarm.

    Our 4-in-1 Alarm protects against four deadly household threats: smoke, fire, carbon monoxide, and natural gas (methane).

    When a carbon monoxide gas leak occurs, it can quickly identify the gas and emit an alarm of 85 decibels(at a distance of 1m) to avoid dangerous accidents and ensure personal and property safety.

    Early warning of smoke, fire, carbon monoxide, and natural gas is best achieved by installing combination alarms on every level of the dwelling, including basements. For maximum detection, install an alarm inside every bedroom, outside every sleeping area, and on every level of the dwelling.

    Low Power Consumption Design the Detector is equipped with 2AA battery, Quiescent Current: 15 (uA). Battery-powered to provide protection even during power outages.
