Our verdict

A First Alert dual hazard alarm that runs on batteries. The seller text describes a can opener instead, so confirm the product before relying on it.

Overview

A living space with gas appliances is where this First Alert alarm belongs, since the title pairs explosive gas and carbon monoxide detection in one battery powered unit. The listing gives little else about how it mounts or sounds.

Choose it for a brand name known in home alarms and a battery powered design that needs no outlet. The big limitation is the data: the description is copied from a can opener and the weight and color fields look wrong, so the sensor details are unconfirmed.

Who it's for

A household that wants warning for both hazards from a single battery unit. The title and product style agree on that function. Someone who needs exact response specs cannot get them from this listing.

Performance notes

An alarm like this depends on its sensors reacting to gas concentration and to carbon monoxide, then sounding a horn. The listing gives no response level, alarm volume or sensor type. Battery power means it works through an outage, but battery life is not stated.

Frequently asked questions

Is the First Alert GCO1CN a can opener?

No. The seller description is written for an electric can opener, but the title and product style both name a combination explosive gas and carbon monoxide alarm. Treat the description as an error.

How is the First Alert GCO1CN powered?

The listing says battery powered. It does not give battery type, battery life or a hardwire option.

What gases does the First Alert GCO1CN detect?

The title names explosive gas and carbon monoxide. The listing gives no detection ranges or gas types beyond that.
