Key Details
When Battery-Only Beats Plug-In
Outlets are rarely where you want a CO alarm. Many sit behind beds and dressers or low on the wall. The CO710 avoids that problem: First Alert designs it to sit on a tabletop or shelf, so you can put it in a bedroom or hallway where people sleep. The sealed battery also means there is no outage gap to worry about.
The trade-off is that a free-standing alarm can be moved. Pick a spot where it won't get covered by clothes or pushed behind other things, and leave it there.
The Display
The backlit display can show the current CO concentration, recent peak CO levels, or the room temperature. First Alert notes that the peak data can help emergency responders after an incident. The temperature mode is a small extra, but it makes the alarm useful enough that people keep it in sight.
Pros and Cons
Pros
- No outlet, wiring or wall mount needed, so it can sit wherever the risk is
- Sealed battery means no battery changes over the life of the alarm
- Shows current CO, recent peaks and room temperature on one display
Cons
- Designed to sit on a surface, so it can be moved, covered or knocked off
- When the sealed battery reaches end of life, the whole alarm is replaced
- No interconnect and no smart features
Bottom Line
Buy the First Alert CO710 for any room where a plug-in alarm would end up behind furniture or near the floor. The sealed 10-year battery and the CO, peak and temperature display make it the most flexible alarm here. Choose the Kidde KN-COP-DP-10YL if you would rather have an alarm fixed to an outlet.
