Kidde i4618AC Battery Powered Hardwire Smoke Alarm, 4 Pack

I recently updated my smoke alarm system with this product and found that they were easy to install and work. Since i installed them approximately 3 months ago they functioned as advertised correctly on two occasions when I left pizzas cooking too long in the oven. The entire system alerts and is audible to a level that gets your attention.

Compatible with current detectors that needed replaced after 25 years in my home. Loud and annoying as they are suppose to be. Shipped fast!

Very easy installation, and easy access to backup battery compartment!

Kidde detectors are my favorite detectors for my rental property. They are hard-wired and also have a backup battery. They are attractive and blend in well with the interior. They are easy to install. First, install the base using a couple of screws and the detectors can be put on by hand.

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.

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

Many firedept will change the battery

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.
