My alarm displays an "88" message. When I press the Peak Level button, it displays an "Err". Removing and replacing the batteries has made no difference. Do I need a replacement unit?

Answer:Unfortunately, yes. The internal CO sensor has been fouled, which could be a result of dust accumulating in the device or it may simply have failed due to age.

I am getting an "Err" message (beeps every 10 seconds or so) even after replacing the battery and cleaning. What can I do to fix this?

Answer:Per the manufacturer, this indicates the alarm is no longer functional. Kidde carbon monoxide alarms have a life span of about 7 years. If yours is less than 7 years old, please call Kidde directly at 1-800-880-6788 for more information.

How long is the estimated life for these? We recently bought a home with one installed. The alarm was manufactured in October of 1999.

Answer:This alarm has an internal CO sensor that will usually be fouled within 5 to 7 years of use. Household dust and dirt will cause the sensor to become less accurate over time. As such, the alarm you have now should be replaced.

I have a Kidde Plug-In that's in place for my pellet stove and another one for my wood burning stove. Where should these devices be placed? Meaning, elevated (I have ten-foot high ceilings) or low to the ground for effective CO detection? And, is there a way to safely test each device (not by pushing the button for a test)?
By Collin C. - NFI Master Hearth Professional on January 15, 2013
Answer:CO alarms work best when placed anywhere between waist to ground level and at least 15 feet away from a potential source of CO. Nearer a bedroom is a good location.
The device could theoretically be tested by exposing it to a known source of CO, such as automobile exhaust or a furnace that has just ignited. I only recommend doing an initial test, as exposing the unit to CO on a regular basis will diminish its effectiveness and ruin the internal sensor eventually.

Where in the alarm do I put the 9 volt battery?
By Chris on March 11, 2014
Answer:On the back side of the unit, there will be a back door with thumb grips which can be removed. Once removed, the power cord for the A/C adapter will be found on the left hand side, whereas the 9 volt battery will be seen on the right hand side.

Does it detect smoke, also?
By Collin C. - NFI Master Hearth Professional on February 28, 2014
Answer:The detector is calibrated only to detect carbon monoxide.
