Kiddei4618AC Battery Powered Hardwire Smoke Alarm, 4 Pack

Bought for direct replacement of alarms I already had that started chirping because they were out of service life. Install was very easy.

These were perfect. I replaced my 20 year old FireX alarms with these. I used the Kidde K A-F adaptor, and it was very simple.

Installation was easy, read the provided instructions. Turned off Smoke Detector AC power breaker in your fuse/breaker box, removed the old (circa 2016). Devices they made them 8 years before starting to false alarm when cooking anything…. I opened the battery compartment for each New device and using a sharpie marker dated the provided battery while in place, hint remove the battery, 1-19-25 and used a pen to mark install date on the attached label on outside edge of the device. Also took pics of the manufacture date on device base for our house records. Battery life could be as long as 5 years (my new devices were manufactured 5-28-2024) by dating batteries lets you track life. Leave the Yellow Battery activation strip in place it hangs out of the battery door/compartment The installation of each device was easy using existing mounting plates and mine had triangle shape plug connectors. If your replacing older Flat prong plug type Kidde offers an adapter plug to todays triangle shape plug. After installation of the smoke detector devices. Turn power breaker back on. The devices will all power up and report by Chirping the low. No battery signal. Go to each device and Pull the Yellow Activate battery strip firmly. After all yellow strips are pulled the chirping will cease. The Green LED on devices will be lit. I’m legally blind and completed the easy installation.

Although they look identical to my 20 year old smoke detectors, they are not. The plug is different, so you have to wire in the one provided with the smokie. The diameter is larger to the mounting ring has to be removed and another one attached. Not a simple take one down and plug in a new one. No fault of the smoke detector. The questionable part is the smoke detectors were not in boxes. I ordered the four pack, and received a bag with four loose smoke detectors. Not in individual boxes like you see them at a store. They appeared to be new, and since I didn't feel like going through the hassle of returning them, I kept them. The seller is in the auto parts business but sells this one non-auto part item.

Easy to order. Work perfectly and arrived on time.

Good product. Replaces the outdated ones I have. With the adaptors, I easily installed 5 smoke detectors.If you have older style smoke detectors make sure to get the correct adaptors. It will make the installation much easier. Very happy with the smoke detectors.

Many firedept will change the battery

The beauty of these alarms is that the batteries can easily be changed without the need to remove the unit from the mounting. Very easy. Also a good price.
