This is for a vacation house. Can I unplug the detector when I am gone for 2-3 months as no one will be ther to hear the alarm?
Asked by: Rob
Yes, this may be unplugged without it sounding alarm. During our summer months, since not running our furnace, both our detectors are unplugged. Plugged them back this autumn and they are working fine.

Does this unit chirp for the entire length of time when the power goes off? The power goes off in the neighborhood occasionally so I need a battery backup that would sound the alarm in the event of CO detection, but not chirping when we're dealing with a power outage.
Asked by: CrTex
I've never heard ours chirp. It used to be my mother's and I'm sure she would have called me if it chirped for her. Did you try putting in a new battery? Maybe the battery is weak and causes chirping, similar to a smoke detector. Also, I hope you test it on a regular basis to make sure it is working properly.

I've seen recommendations to have CO detectors at eye level to read the display. For plug in versions, how can you do this since most wall outlets are close to the floor? Is it acceptable from a safety and fucntional standpoint to use outlets that are about a foot from the floor? And this model in cany case doesn't have a display.
Asked by: AWA
I have not seen any contradictory info regarding placing the detectors along a regular floor outlet. These do not have any display except the indicator light which is easy to see. I found they actually make a fair night light when I get up in the middle of the night, but not bright enough to keep me awake.

Kidde Plug-In Carbon Monoxide Detector with AA Battery Backup (6-pack) is rated 4.6 out of 5 by 542.

At 2am one morning last month, this detector sounded its alarm. I unplugged it and tested the batteries and compared them to new batteries on the same tester, just to be sure. Knowing the batteries were good, I reset the detector, plugged it back in and went back to bed. I assumed it was fluke. We had had this detector for many years and never heard an alarm unless the batteries were going bad. But at 4am, it sounded again. This time I called 911. When the fire dept and sheriffs dept and utility company employee all showed up with their carbon monoxide detector units, they told me that I really did have a leak. It was the venting on the tankless water heater that had collapsed and was allowing the carbon monoxide to come back into the house. So, thank you Kidde, for saving our lives.

Rated 4 out of 5 by from Good alarm This alarm is powered by an AC outlet but also has a battery backup in case you lose power. The batteries come already installed. All you need to do to use the battery backup is to remove a plastic tab that is coming from the battery compartment. The light on the front indicates if something is wrong with the unit or air quality. Green is good, red is bad. The instructions state that the unit does self checks to ensure everything is working correctly. There is a test button on the front. When pressed, the alarm sound is nice & loud & will certainly alert most people that something is wrong. I would definitely take the 5 minutes to read the instructions when you install this. There is a lot of good info in there, and some minor details that are good to know about this device. Lastly, this alarm is good for 10 years once powered up. After 10 years, annoying alarms will force you to throw it away.

The unit hasn't sounded, so I suppose that means it either takes accurate readings of the fresh air in my home or it doesn't work. ;) The unit was marked with a manufacturer date of 2018, so the unit has a full life to live before it sounds the end-of-life chirp.

This product met my expectations in being easy to install etc. It is hard to evaluate an alarm product unless it actually performs when an alarm condition exists. Since to my knowledge no such situation has existed I cannot say whether it is excellent or a failure.
