Overview
A renter or homeowner who wants a carbon monoxide alarm with no wiring gets a plastic unit that stands on a surface and runs from a battery built in for its whole life. An electrochemical sensor does the detecting, and a backlit display shows readings.
The sealed battery means no battery changes for the life of the unit, and the display shows current and peak levels as well as temperature. The limitation is that it is a standalone unit, so it does not link to other alarms.
Who it's for
A bedroom nightstand, hallway table or rental unit where drilling is off limits suits a standalone alarm like this. Anyone who needs alarms that link together across a house should look at an interconnected system.
Pros and cons
- Sealed ten year battery
- Backlit digital display
- Shows peak CO reading
- Test and silence button
- Standalone, no interconnect
- CO only, no smoke sensing
- Sealed battery cannot be replaced
- Tabletop placement, not wall mount
Performance notes
An electrochemical sensor reacts with carbon monoxide in the air and produces a signal that rises with concentration, which the display reports as a current and a peak value. The horn sounds when levels climb too high, and the test and silence button checks the alarm or quiets it.
