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 πŸ˜‰) 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? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/82732411-kidde-kn-copp-b-lpm-monoxide-alarm-white](https://www.desertcart.co.uk/products/82732411-kidde-kn-copp-b-lpm-monoxide-alarm-white) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-17*
