Editor's Pick: If your kitchen connects to a hallway, a regular alarm tends to go off easily when cooking produces a lot of smoke. This one uses photoelectric sensing, so cooking smoke and steam are less likely to trigger it, saving you a lot of false alarm hassle. The battery is a sealed lithium battery inside, so once installed you don't have to worry about it for ten years, sparing you from hearing the low-battery beeping at midnight and having to drag out a ladder to change batteries. Installation is just a few screws, no wiring and no electrician needed.
