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. Plus, peak level memory records the last time carbon monoxide was detected or when the unit was last tested. 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.

This key feature adds an advanced level of protection that you have come to expect in a Kidde manufactured product. The battery operated CO alarm includes multiple mounting options, allowing installation on a wall or tabletop. This alarm has been carefully designed and tested to detect CO concentration in a residential environment. It provides continuous monitoring of CO levels, even during power outages when many CO incidents occur. The digital display feature allows for easy viewing of carbon monoxide levels from 30-999 PPM (parts per million). The KN-COPP-LPM will also detect and store concentration CO levels as low as 11 and up to 999 PPM with its peak level memory display. This alarm includes a snap-on cover that gives immediate access to the batteries and a safety feature that makes it difficult to close the cover without the batteries being installed. Updates digital reading every 15 seconds, allowing you to see if levels change. The peak level memory displays the highest CO concentration measured since the last reset. The test/reset button tests CO alarm circuit operation and allows you to immediately silence the alarm. A low battery signal alerts users when the batteries need to be replaced. Includes informative LEDs: green LED for normal operation, red LED for alarm. The alarm alerts user to replace CO alarm after 7 years of operation.Sensor: Electrochemical. ## Features - Electrochemical sensor technology detects CO gas - Easy installation, no wiring needed, detects during a power failure by operating on 2-AA batteries (included) - Conveniently designed & portable: simple to install on a wall of your home or place on a tabletop - Green LED indicates power to the smoke detector, while an 85-decibel alarm & a red LED indicates the presence of carbon monoxide - Peak Level Memory records the last time carbon monoxide was detected or when the unit was last tested - Test-Hush button makes it easy to test the carbon monoxide detector or temporarily silence the low battery chirp warning - UL listed with a 10-Year limited manufacturer warranty on the alarm only (not a battery performance claim).

Should it be near the ceiling or near the floor?** A: After spending 40+ years in the car business I have this to say: (everyone seems to be telling what they did or didn't do for a living 😉) I have that if you mount them from one foot above the floor, to one below the ceiling, or even on it..it is still better to have one than NOT to have one! No matter where it is!! It's like ANY tester or alarm, if you don't have one..that's when it will get you killed. Either way, most people will end up mounting them where they are out of sight. No matter what the papers or anyone tells you. Put at least one on each floor..and pray you never need them. Simple as that! Oh..the 40+ years in the car business Taught me this!l, Any idea how much CO is put out into the air of a car dealership over the course of each day, working on from 20-200 cars a day? A LOT! So again, mount it anyplace..but just MOUNT it! Good luck to you all. ;) **Q: how is it installed** A: There is no installation required. Just put in the batteries as shown and it's ready to go. I move mine from room to room. You can mount it on a wall if you want. **Q: Can the alarm be run with rechargeable NiMH batteries?** A: The User's Guide for this product, and stamped on the item itself, are model numbers of alkalines, (Duracell MN1500 or MX1500; Energizer E91, etc). However, it does say "Use of a different battery may have a detrimental effect on the alarm operation." Thank you for calling my attention to this, because the rechargeables I use are NiMH. The item comes with batteries. **Q: is it a plug in** A: This is not a plug-in. Operates on 3 AA batteries and acan be easily mounted on wall. Love it. ## Frequently Bought Together - Kidde Carbon Monoxide Detector, AA Battery Powered CO Alarm with LEDs, Test-Reset Button, Low Battery Indicator, Portable - Kidde Carbon Monoxide Detector, Battery Powered CO Alarm with LEDs, Test-Reset Button, Low Battery Indicator, Portable - 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/3765263-kidde-carbon-monoxide-detector-aa-battery-powered-co-alarm-leds](https://www.desertcart.pt/products/3765263-kidde-carbon-monoxide-detector-aa-battery-powered-co-alarm-leds) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-08-04*
