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. From the Manufacturer The Kidde KN-COB-B-LPM battery operated carbon monoxide alarm utilizes sophisticated electronic components to protect you and your family from the dangers of carbon monoxide. This alarm includes a slide-out battery door that gives immediate access to the batteries and a safety feature that makes it difficult to close the door without the batteries being installed. Inside cover of battery door features quick reference guide for what to do in case of an alarm. This easy-to-install alarm is suitable for all living areas and has a 7-year life and a 5-year limited warranty. The Kidde KN-COB-B-LPM provides you and your family with a loud warning signal against the dangers of elevated carbon monoxide levels in your home. The battery operated CO alarm provides continuous monitoring of CO levels, even during power outages when AC-only units are not providing protection. This unit is battery operated and has 3 AA batteries included. The test/reset button tests the unit for proper operation and also resets the carbon monoxide alarm. A low battery signal alerts users when the batteries needs to be replaced. A green LED flashes every 30 seconds to indicate the unit is operating properly. The green LED will also flash before a CO reading is taken and when any button is pressed. A red LED will pulse and a loud alarm pattern will sound when a dangerous level of carbon monoxide is detected. The carbon monoxide alarm pattern is 4 short beeps, followed by 5 seconds of silence, followed by 4 short beeps with a corresponding red LED flash. This cycle will continue for 4 minutes and then change to 1 cycle every minute until the device is reset or the CO is eliminated. The alarm alerts user to replace CO alarm after 7 years of operation. ## Features - Electrochemical sensor technology detects CO gas - Easy installation, no wiring needed, detects during a power failure by operating on 2-AA batteries (included); Install on a wall of your home or place on a tabletop - Green LED indicates power to the carbon monoxide detector, while an 85-decibel alarm & a red LED indicates the presence of carbon monoxide - Event Memory records the last time carbon monoxide was detected or when the unit was last tested ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B004Y6V6K4 | | Alarm | Carbon Monoxide Detector Alarm | | Best Sellers Rank | #9,487 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #19 in Carbon Monoxide Detectors | | Brand | Kidde | | Built-In Media | mounting hardware (screws, drywall anchors), user manual | | Color | White | | Customer Reviews | 4.7 4.7 out of 5 stars (36,228) | | Enclosure Material | Carbon | | Global Trade Identification Number | 00047871088720 | | Item Dimensions D x W x H | 1.5"D x 4.5"W x 2.75"H | | Item Type Name | Carbon Monoxide Detector | | Item Weight | 8 ounces | | Manufacturer | Kidde | | Manufacturer Warranty Description | 10-year limited warranty | | Mfr Part Number | KN-COB-LP2 9CO5-LP2 | | Model Number | KN-COB-LP2 | | Number of Items | 1 | | Operating Humidity | 10%-95% relative humidity non-condensing | | Power Source | Battery Powered | | Product Style | Clamshell Packaging | | Sensor Type | Electrochemical | | UPC | 047871088720 | | Unit Count | 1 Count | | Upper Temperature Rating | 100 °F | ## Product Details - **Alarm:** Carbon Monoxide Detector Alarm - **Brand:** Kidde - **Color:** White - **Item Weight:** 8 ounces - **Operating Humidity:** 10%-95% relative humidity non-condensing - **Power Source:** Battery Powered - **Product Dimensions:** 1.5"D x 4.5"W x 2.75"H - **Sensor Type:** Electrochemical - **Style:** Clamshell Packaging - **Upper Temperature Rating:** 100 °F ## Images ![Carbon Monoxide Detector, Battery Powered CO Alarm with LEDs, Test-Reset Button, Low Battery Indicator, Portable - Image 1](https://m.media-amazon.com/images/I/717SCEOQCDL.jpg) ## Available Options This product comes in different **Style** options. ## 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. ## Frequently Bought Together - Kidde Carbon Monoxide Detector, Battery Powered CO Alarm with LEDs, Test-Reset Button, Low Battery Indicator, Portable - First Alert SMI100, Battery-Operated Smoke Alarm, 1-Pack - Kidde Carbon Monoxide Detector, Plug In Wall with AA Battery Backup, Test-Hush Button --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/6795198-carbon-monoxide-detector-battery-powered-co-alarm-with-leds-test](https://www.desertcart.pt/products/6795198-carbon-monoxide-detector-battery-powered-co-alarm-with-leds-test) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-08-31*
