Product description

Will the alarm still work during a power outage?

This product supports both plug-in and battery-powered modes, ensuring it continues to operate even when the power is out.

Are batteries included?

Batteries are not included. This allows for safer shipping and gives you the freedom to use your preferred battery brand.

Will the light from the CO alarm be too bright in the bedroom and affect sleep?

Our latest model supports DIY screen brightness adjustment, so you can set it to your comfort level at night.

My elderly family member has hearing issues. Is the alarm loud enough?

The alarm supports adjustable volume. At maximum level, it is loud enough for those with reduced hearing sensitivity to notice.

Where should I install the carbon monoxide alarm at home?

We recommend installing it near bathrooms, kitchens, hallways between bedrooms and bathrooms, garages, or areas with gas appliances. Avoid installing in areas with heavy oil smoke or excessive moisture.
