KiddeHeat Detector, Hardwired with Battery Backup & 2 LEDs, Interconnect Capability, Ideal for Garages

I had a combo smoke and carbon detector in my un-insulated garage that recently started tripping the entire system around 12 noon each day (the peak of daytime heat in this recent heatwave). It is a finished garage, but has attic space above with no insulation and also windows to let light in. With the added humidity of being in the south during this latest heatwave, the temperatures were well above 100 degrees, which is what smoke detectors are rated for. I researched and saw that these are made for garages or any other space where smoke isn't necessary, as it only triggers above 135 degrees. Remember, this is in addition to the rest of your system inside, etc. I swapped the smoke detector for this heat alarm and no more issues. I added a plug-in carbon detector for good measure. Perfect alarm for its purpose!

These are as easy to replace as just changing the battery. You unscrew the detector, pull out the power wires, then use a new detector with new battery (instead of the old one with new battery) before putting it back. Easy enough once you can reach the ceiling to do it.The company is very soft on when to replace. The support staff mentioned that a double beep indicates failure while a single beep is just asking for a new battery. So far so good. The unit hadn't actually failed. However, that same advisor suggested they should be replaced anyway as they were 15 years old. The warranty is 5 years, so she advised replacing them. I opted to replace since we have 16 foot ceilings and I would need professional help to reach them--costing more than the new detectors. However, these units appear to use a metalic "fuse" that melts at the appropriate temperature indicating a fire and triggering the alarm. Not obvious how this can go bad--ever.

It has been said that smoke detectors are to be replaced every 10 years (at least in my state ) I already had hardwired Kidde both heat and smoke detectors so it was very easy to take old ones out and plug new ones in. Good products both.I had to use heat ones in family room where fire place is and near stove in kitchen hallway. In an abundence of caution I also put canbonmonoxide ones in bedroom.These things could wake the dead !

Smoke detectors are recommended to be in hallways outside bedrooms. Sigh.Our hallway outside our bedroom is very "conveniently" (hint: NOT) right next to the kitchen, and very close to the gas oven, and we had a ionization/CO alarm that gave us a scare when we first used the oven and called the fire department to confirm if there is any CO leak that we didn't know of when we bought the house. That's when we learned all about "nuisance alarms". The alarm from the apartment where we used to live rarely went off while we cook so - yeah, this annoyance was new to us. Given we have about 10 of these hardwired together when one went off and I hate loud noises, I knew the smoke alarm will be my least favorite of all household electronics.We got this to replace the one next to the kitchen -- it was easy to install and test (with earplugs), and so far it did not throw any tantrums during frozen pizza nights like we used to have. I did not have to replace the existing Kidde wiring harness -- just the mounting plate. It integrated well with the variety of Kidde alarms we currently have (we plan to replace the nuisance ones at some point in the future).I also installed this in our basement to replace the ionization type that we have right beside the laundry/furnace room (that also went off when we are using our flat iron). No nuisance so far, although we make sure we don't put steam directly beneath it. Of course, I also got a separate CO alarm for the basement, though, for added protection.4-stars because while I'd rather chuck each one of these out into the dumpster, I have to have these for my own safety. I don't love it. I like it enough because it saves me from having frequent heart attacks.I wish they'd be able to manufacture more alarms that's ear-friendly, not ear-splitting, while being able to alert you with the situation. Or sound out a voice warning a few minutes before it starts beeping like crazy. It's just ironic how you're supposed to "remain calm" when these things go off, but I usually feel like joining my kitty under the couch when it starts shrieking.

Will work with most 120 interconnected Kidde smoke and co detectors. Replaced the smoke in garage with this heat. Per NFPA smoke detectors are not allowed in a non conditioned space such as a garage or crawlspace.

Most houses when they are built are usually fitted with the absolute minimum required photo sensitive fire detectors. Newer houses also have a carbon monoxide detector built in, which has a limited life and has to be replaced more often.For the kitchen or kitchen living space, if you have a gas stove or you bake foods using high heat a lot, chances are you'll get some smoke. The single photo sensitive detectors will often go off with false positivesWhen I spoke to Kiddie, they recommend this detector for spaces where by-products of gas cooking or high heat cooking smoke will set off a standard detector. For me, I have a Thermador 6 burner pro range and even with a 1200 cfm hood, I got a lot of smoke detector false positives. I swapped out the original Kiddie for this one and it is plug and play. I did not have to wire. I just unplugged the old and plugged in the new.Depending on the original detector, you might also have to swap out the base plate. I just loosened the screws on the electrical box, twisted off the old and then reversed the process.All up, the work required was about 10 minutes and I now have a smoke detector (actually it detects high heat over smoke) that does not go off every other day. I additionally installed a plug in carbon monoxide detector, so that I don't have to replace my smoke (heat) detector every 10 years.
