## Overview

The Kidde Carbon Monoxide Detector (model KN-COB-LP2) uses advanced electrochemical sensors powered by 2 AAA batteries (included) for reliable, wire-free installation and continuous CO monitoring—even during power failures. Featuring an 85-decibel alarm, red and green LED indicators, and event memory, this portable device offers professional-grade safety with simple setup and trusted UL certification.

## Description

The Kidde Carbon Monoxide Detector, Battery Powered CO Alarm with LEDs, Test-Reset Button, Low Battery Indicator, Portable, model 9CO5LP2, is a carbon monoxide detector that uses electrochemical sensor technology to detect carbon monoxide. The CO detector is powered by 2-AA alkaline batteries located in the back of the unit, providing easy installation & no wiring, plus coverage during a power failure. The alarm is conveniently designed and portable enough for travel - simply install it on a wall or place it on a tabletop. When carbon monoxide is detected, an 85-decibel alarm will sound & a red LED will flash. A green LED indicates that the alarm is receiving power. The test-hush button allows you to test the battery operations as well as temporarily silence the low battery chirp warning. Install a smoke detector & carbon monoxide detector on every level of your home and near bedrooms to help keep your family safe from fire & poisonous gas. UL Certified with a 10-year limited manufacturer's warranty.

Review: Used and unreliable - Sent me a previously used product -plastic packaging open and batteries lying out. Not new, not reliable!!
Review: I’m content with this carbon monoxide alarm as it delivers simple, reliable protection without any fuss and at a very reasonable price. Installation was a breeze right out of the box: no wiring, no tools, just mount or set it where you need it, and you’re good to go. Pros: ✔ Easy to install - literally no wires or complicated setup. ✔ Great price for essential safety gear - excellent value for home protection. ✔ Clear LED indicators and a loud alarm make status obvious. ✔ Battery-powered - works during outages and doesn’t rely on wiring. Cons: ⚠ No digital CO level display but understandable considering its price. Overall, this CO detector does exactly what it’s supposed to. I’ll update this review if I notice anything unusual with battery life over time, but so far it’s been dependable and worth the investment for peace of mind.

## Questions & Answers

**Q: Why is the 2 pack more than 2 times the price of the single detector?**
A: Be aware that the sensor has a 7 year life.  At least that is the information I got from Kidde.  I am replacing my 2 units purchased in 2011.... Otherwise they appear to be good.  I am not sure if other brands have a similar lifespan.

**Q: How far apart are the mounting holes?**
A: I just installed three of the Kidde CO Alarm Model KN-COB-LP2.  The holes are exactly 3.00 inches (7.62 mm) apart.  I recommend sliding off the back plate and using it as a template, though.  Install One screw, or in dry wall using the provided plastic anchors, Drill one 3/16" (4.75 mm) hole and install the screw. Then hang the back plate off the single screw and level it and use a pencil to mark the exact center of the second hole.  Install the second screw.  Check with back plate to see if they align sufficiently (My first one was off a little because I did not follow the procedure above, but it was still OK, just not perfect).

**Q: your cob b lcm  coc allarm is 15$ 6 is 99$ .  why does quantity coct more**
A: This seems to happen a lot on Amazon. The answer for the consumer is just order multiples of the cheaper priced one. so say buy six of the 15's for 90 instead of paying an extra 9 to bundle. Perhaps there is a legit answer sometimes such as bundled shipping goes up for the seller if it's sent from them and not Amazons warehouse. Anyway most often when I see this I just chuckle and of course the advantage is in my court as long as the stock is available to order any number if say I only need 3 or 5 I can skip the multiple bundles for more money and just select the quantity of the single one I'm ordering. Also works if it's say two is cheaper than 4 etc. Do the math and you can chuckle at the silly world we live in these days. Chill out and stay safe it's better for your heart everyone.

**Q: Would this device work in a 6' x 6' hunting blind with a Mr. Heater heating unit?**
A: I believe this would not be a good fit for the Kidde. The conflict comes with a mr. Heater  unit.
