## Description

The Kidde Carbon Monoxide Detector, AA Battery Powered CO Alarm with LEDs, model 900-0146, 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. 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.

## Questions & Answers

**Q: How is the unit mounted?  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.

I purchased this kidde co detector for our car or when we travel. I got this brand coz it’s UL-certified, so I know it meets safety standards and has been properly tested that alone gives me confidence it’s reliable. Setup was easy since it runs on AA batteries, no wiring or complicated installation required. The LED indicators make it simple to check status at a glance, and the test/reset button works smoothly. It also says there will be low-battery alert, so it won’t quietly stop working without me knowing. The portable size is another bonus it’s easy to move if I want coverage in other places, or even take it along when traveling. For anyone looking for a trusted, approved, and low-maintenance CO alarm, this one really covers the essentials. You have to do research before buying
