2. 9 star rating. The biggest issue is the one the plagues many smoke detectors, excessive false alarms. In addition, this model was part of a large recall by Kidde in March 2018 over a manufacturing error that rendered one of the dual sensors inoperable. Free replacement alarms are available for defective units; you can find more information at the Kidde web site. If your home lacks a hardwired network of interconnected smoke detectors, and tackling the job of wiring a whole house smoke alarm system is too much for your DIY skills or contractor budget to allow, stand alone battery operated smoke detectors remain a reasonable second choice. Tops among these is the First Alert SA320CN Est. $20, a dual sensor, battery powered smoke detector that earns positive feedback overall. It's been tested by Consumer Reports, and earns the top rating for detecting both smoldering fires and flaming ones, though not a recommendation presumably because it cannot be interconnected with other alarms. User reviews are positive, including a 4. 6 star rating at Home Depot, and recommendations from 98 percent of the nearly 100 owners that leave reviews.

It is best that homeowners are able to see the difference among these different types and see how they work, before deciding on which ones to buy and install in the house. The type of sensor installed in a smoke detector may also dictate the price range, since there are sensors that have more expensive components than those of the other types. Among the types of sensors presently used by several manufacturers of smoke detectors are the ionization type, the optic sensor – also called photo electric sensor, the air sampling sensor, and combination type sensors. A smoke detector with an ionization type sensor uses what is called radio isotopes that produce ionization in the air. The process is quite technical, but what this type of detector contains is ionized air molecules in a chamber inside the device. The ionized air carries electrical current and maintains that current, until something disrupts the air molecules.
