Kidde I4618 Hardwire Smoke Alarm I4618

False alarms at 2:00 a.m. these trigger randomly at 2:00 a.m. no fire no nothing alert it. We pressed the buttons to hush and then reset them all and they still go off. We then went to a 24-hour supermarket to get new batteries, replaced all the batteries and it still goes off. Had to get the fire brigade out due to CO2 concern. Nothing. There has to be far better products than these. This has happened more than once. We replaced batteries every 6 months and check test them regularly

I feel like most of you one-star reviewers probably are in desperate need of a class on Smoke Alarms. This has been an outstanding brand and model for me. In the house I've been in (for decades), we have eight of these and I have relied on three different complete sets. (YES! LESSON ONE! Smoke Alarms have a LIMITED lifespan and must be replaced!!!). Each set for me has performed exactly as advertised. FIVE STARS is truly the only rating for this product. Now.... here's your free class, people: LESSON ONE: As I said, smoke alarms is a technology that has a limited lifespan. They must be replaced. Smoke Alarms will start chirping, or otherwise alert you, when they have reached the end of their lifespan. AND THEN YOU MUST REPLACE THEM. Do them all at once. It's truly very simple. LESSON TWO: Next, if you're not changing your batteries annually, you're actually not doing what you should be doing. My reminder is my birthday. I change the alarms at my birthday. And so guess what I remember to do every year? Put fresh batteries in the smoke alarms. This is not rocket science, people. Set your birthday as the date to do a list of annual things. LESSON THREE: If your smoke alarms are running through a battery faster than you think they should be (and NO, batteries should NOT be lasting you years and years), blaming the smoke alarm should not be your first go-to. This is especially true if multiple alarms are draining batteries too fast. YOU SHOUL D BE SUSPECTING YOUR WIRING!!!! The power source is an interconnected source. In fact, my house has a separate Circuit Breaker for Smoke Alarms. Have you checked your circuit breakers???? Is power even getting to your alarms, or are they running 24x7 off of battery power??? LESSON FOUR: (This is for the complainers that they've all gone off at the same time). I hear you. I do. I had no idea smoke alarms were interconnected and was SHOCKED when this happened to me. When ONE ALARM goes faulty in the interconnected set of alarms, THEY ALL GO OFF. It's truly terrible. I think that having the alarms be interconnected in a house is foolish. I can hear the alarm going off at the other end of the house, and so I do NOT need them ALL blaring at me. But here's the good news, please. READ THE INSTALLATION INSTRUCTIONS: It is a simple piece of cake to switch each alarm so that they are NOT interconnected. I know interconnected versus independent is up for opinion. I get it. But I will never install interconnected smoke alarms, ESPECIALLY in a one-story property where I'm sure to hear other alarms. I do NOT need to ever again hear them all going off when it's just one of them that's got something to say. Save yourself the headache, and save the manufacturer your poor review simply because you don't like what happened.

If I could give this zero stars I would. You can't even replace these. They start alarming very loudly and yelling “fire”. We had to take them down. Now we don't have any and we bought enough to replace all of them as we were told they all had to be replaced after five years.

These were installed in my new home by my builder November 2024 and they randomly went off at 4am. We were all so scared out of our beds and the dogs were pretty upset as well. And the alarms keep going off and this is after changing the battery and cleaning it with the vacuum and checking the humidity. Ours are hard wired and we shouldn't need batteries but I was willing to try anything to get it to stop. These are junk. We will have to replace all of them if we plan to get any sleep. Who will reimburse us the cost for this junk? I wonder where they were manufactured…

It was hard to find elsewhere.
