Your cart is empty.The Kidde i4618 is an AC/DC powered, ionization smoke alarm that operates on a 120V power source with 9V battery backup. This alarm uses ionization sensing technology. Ionization sensing alarms may detect invisible fire particles (associated with flaming fires) sooner than photoelectric alarms. Photoelectric sensing alarms may detect visible particles (associated with smoldering fires) sooner than ionization alarms. The front-loading battery door allows user to change the battery without removing the alarm from the mounting bracket making battery replacement easy and convenient. This smoke alarm is available in a 6-piece cut case with tray for easy display as well as a 6-piece bulk pack for contractors and property owners. This unit is a UL Listed product with a 5-year limited warranty. Kidde strongly recommends that both ionization and photoelectric smoke alarms be installed to help insure maximum detection of the various types of fire that can occur within the home.

I bought these to replace my old Firex alarms that were about 12 years old. I was encouraged by the review from the man who said he wasn't handy but found the rewiring to be straightforeward. So I bought of these and have taken them out a number of times but am just flummoxed. I don't see any pre-stripped wires, just the three prongs sticking out from the back. Are there any instructions? I can't find them on the website and of course the help line is open only during business hours, not during the evenings or weekends when I try to install these.Currently, because I did find the breakers that control the alarms and have that turned off, we are without any smoke alarm protection. I bet this is some small, obvious thing, but I can't figure out where to get to these wires in order to rewire the new alarms. Any help will be deeply appreciated.UPDATE:Finally, I hired an electrician to install the alarms. Once I saw how he did the first one, I realized I could have installed them all very easily. The info I was missing was that the connectors for the old Firex had to be removed first--as you do that you will see where each of the the new wires needs to go. A ten minute operation.You do need to change out the holder, the piece that attaches to the ceiling to which you screw in the alarm box. But that, too, swaps out without a problem.The best part of these alarms is that you can change the batteries from the front of the box. In other words, you don't have to remove the alarm from the ceiling to get at the battery compartment in the back. The battery compartment is behind a sliding door on the front of the alarm.

I don't know how these are reviewed so high here, on Kidde's own website they have 1.6 stars with many people complaining of the same thing I am. I Bought these to replace some aging smoke detectors, and since then they've been giving me constant problems to the point while still relatively brand new they all went in the trash. They will randomly go off for no reason, and finding the one that alerted is impossible since the light codes don't work as the should. In the meantime you are running from alarm to alarm to silence them and figure out which one alarmed, and it's impossible, and they won't shut up. The silence button does nothing. Turning off the breaker doesn't work since the batteries keep them all going, so you have to go to every single one to pull the batteries out. On top of that two of them keep giving the 30 second alerts to signal a low battery, even with fresh batteries installed that I verified with a voltmeter. Somehow all of these problems always pop up in the middle of the night. These were an expensive mistake both in terms of money and headache.

Fantastic deal. Exact model recommended to replace my discontinued one which needed to match the other 3 that still work. I was very surprised to get free shipping from US to Canada. That only seems to happen from China, never the US
