Kidde i4618


This model is another convenient alternative to keep in mind if you want to make sure that your house isn’t on the brink of disaster anytime soon.

The smoke detector is affordable and convenient, but it doesn’t come with the same cutting-edge features boasted by other products such as the Nest we’ve mentioned in this same selection.

Based on the info that we came across, it looks as if the device is rather easy to install.

The neat thing about the unit is that it can be connected to other Kidde devices, in case you already own a smoke alarm and a heat alarm.

Besides, it’s worth adding that the product has been outfitted with a front loading battery door, which means that you won’t waste any precious minutes when changing the battery, which by the way, is included in the deal.



The configuration of this product might be different compared to that of older smoke detectors you might be trying to replace with this one.
