Questions & Answers

Does this ever need to be replaced?

It won't stop beeping like every 30 seconds.
Asked by: Michele
First, check your battery. From Kidde's website: "The unit shall also indicate a low battery warning utilizing each of the following methods: a blinking dot will be displayed and the sounder will chirp every 15 seconds, the display will alternate between “Lb” (low battery) and CO reading while chirping". Next, depending on how old the unit is (typically > 5 years old), the gas sensor gives out, and chirps as well. If neither of these solutions solves the problem, go to Kidde's website and see the support section for more answers.

Where is the best place to install the alarm. I have mine in the kitchen. Should it be in the hall way??

Asked by: Bunny
The best place to put a CO alarm is in your bedroom. If it goes off, you want to be sure it wakes you up; even from a deep sleep.

I have LP propane gas heat in my house. Will this detector sense any a gas leak near the unit?

I have LP gas. Would this sensor pick up if there is any leakage of gas in the area? I don't know if the off put of LP gas is carbon Monoxide.
Asked by: questioner
I think you're asking two different questions. If you have a model that detects combustible gasses as well as CO, then yes it will detect leaking natural gas and LP gas. Carbon monoxide (CO) is the same, no matter what is burning. CO is produced by incomplete combustion of anything flammable.

What would happen if you did not connect a battery to the alarm detector? Would it automatically sense LOW BATTERY and continously beep?

Plug-In CO Alarm with Digital Display and Battery Backup (6-Pack) is rated 4.6 out of 5 by 122.
Rated 5 out of 5 by from Let me first say that I'm a firefighter. I respond to literally hundreds of calls each year for ... Let me first say that I'm a firefighter. I respond to literally hundreds of calls each year for "Carbon Monoxide Alarm Sounding". In a very small percentage of these calls we find CO, verified by very accurate monitors that we carry. The remainder of the calls are caused by, in order of frequency, dead batteries, expired detectors, or malfuncioning detectors. Please don't misunderstand me; CO is deadly and every time your CO detector goes off it should be taken as a true finding. Get out of the home and call 911. With that said, replace your batteries twice a year, replace your detector when the manufacturer says, and buy this detector. I can't remember the last time I found a Nighthawk that was wrong about CO. It's what I have in my house.

Rated 5 out of 5 by from Easy and Reliable CO Alarm I have owned various versions of this trusty alarm for many years. Never had a problem. Pretty much idiot-proof. It is simple to install, and then you can forget about it unless there is a carbon monoxide issue. I have always tested mine by covering them with a large plastic bowl and then blowing a few puffs from a cigarette into the bowl. Sure enough, the display showed a slight amount of carbon monoxide. This unit can be plugged into a wall socket, or the internal cord can be released so that it can rest on a table, or can be mounted higher on a wall. With the battery back-up, this is a great little device that just might save your life someday, so get several and keep at least one close to where you sleep.

I always perform strenuous research on life safety items, as I myself have interacted with many different types of gas detector during the course of my career. This CO detector is easy to install, operate, read CO levels, and just daily interaction with device. I chose to wall-mount mine and have received numerous compliments from friends and neighbors (the ones I allow to view my homes mechanical center that is). Only reason I did not give the Kidde KN-COPP-3 5-stars is the top keyhole mount is part of the battery/power cord access door and does not, in my opinion, make for the most solid wall-mount configuration. Other than that one simple observation this is a great CO detector, and it compliments my Kidde i4618 smoke detectors and Kidde KN-COSM-IB combo smoke/CO detectors that are installed in the bedrooms and hallways of my home.

Make sure to write the date you install for your records and when to replace.
