The Kidde Silhouette is a low profile AC/DC powered, ionization smoke alarm that operates on a 120V power source with a sealed rechargeable battery backup.

This alarm uses ionization sensing technology. Ionization sensing alarms may detect invisble 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.

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.

This smoke alarm is available in a 4-piece cut case with tray for easy display. This unit is a UL Listed product with a 10-year limited warranty.

5 of 5 very sleek design October 1, 2012
Reviewer: Anonymous Person  
I saw my this low profile smoke alarm at my friend's house. At first, I was asking her if it is a security system of some sort. She told me that it is Kidde low profile alarm. I immediately did some research about this alarm. After reading about the pros and cons, I've decided to change my existing Kidde alarm with the low profile one. My existing alarm was almost 10 years anyway. I'm sold when I read that this low profile comes with rechargeable battery back up that can last up to 10 years. I'm so in love with this low profile, it looks sleek, blends in with my ceiling. Most alarms that I know of has round shape. This is square looking and it looks more expensive that it is. The only downside though, I don't think it comes in carbon monoxide.
