About This Product
This First Alert combo pack gives you two solid pieces of safety gear for your home.

First up is the SCO5RVA — a battery-operated combination smoke and carbon monoxide alarm.

It uses a photoelectric smoke sensor that's great at catching slow smoldering fires and cuts down on annoying false alarms from cooking.

The electrochemical CO sensor is the most accurate type out there.

Runs on 2 AA batteries (included), and the test/silence button lets you quiet false alarms or check that it's working.

Different horns and lights tell you whether it's smoke or CO, so you know what's going on.
The other unit is the CO615A, a plug-in carbon monoxide alarm with battery backup and a backlit digital display that shows CO levels and battery status — easy to read even in the dark.

Plugs into any standard outlet and has a 6-foot cord so you can mount it on the wall or set it on a shelf.
It also has a low-battery chirp and an end-of-life timer so you know when to replace it.
Place one on every level and near sleeping areas.

First Alert is a brand people trust, and these detectors are simple, reliable, and could save lives.
