Kidde Smoke & Carbon Monoxide Detector, AA Battery Powered, LED Warning Light Indicators, 2 Pack

Very easy to install and easy to test - the loud alarm is more than sufficient to wake from a deep sleep. After installing the mounting plate - two screws with wallboard anchors, simply remove a sticker preventing battery and terminal contact and twist the unit to secure to the mounting plate. Again, then test and the alarm is loud! If you're comparing with others, do pay attention to see if the unit is UL approved, not just tested to UL standards. Many of the cheap ones from china are NOT tested and approved by UL. If you read the low rating comments on those cheaper units the stories should give you sufficient pause to spend more for quality that protects your life.

These seem to work pretty good but after a few weeks they started chirping, we had lithium batteries in them they wouldn't quit chirping until we put Alkaline batteries in .

This smoke detector is multi-purpose as a CO2 detector. Easy to install.

Someone seems to have thought of everything a home owner could get wrong and design this detector so it was as easy as possible to install. How would I improve it? Put a label on it to remind the owner to check the battery every 2 yrs. Also, study other smoke detectors so that your unit can fit directly into the existing footprint and even anchor screws. One of the biggest complaints I have about smoke detectors is that a home owner wants to cover up the previous paint not try to cover up old, perhaps unsightly paint exposed by a new smoke detector. You can buy the same paint but it won't match a paint that might be >5 yrs. old. So, why make your customers go through the hassle: going to the paint store, buying a $32 pint of paint that is hand-mixed to match someone's flavor of the month. And, the paint won't match anyway. I had this happen three times with a home I was selling. My point? match the footprint. Talk to your competitors if you must and agree on one. Windshield wipers have the same problem. In their case, they include kits to match each make --- Ford, GM, Honda, Kia, BMW, etc. The customer pops in the adaptor kit and the wiper fits into the slot on the wiper arm. Bingo!

Died after one year. Continually has 3 beeps after ordering on October 24, 2024. Batteries replaced, detector reset, still does not work. Hung in place not subject to bathroom steam or oven. Temperature not a factor either. Bought thinking it was a good value. Don’t waste your time or money.
