About This Brand

Kidde owns FireX branded units and offers the Nighthawk and Silhouette lines. Nighthawk comes in plug-in and battery operated units. Price range of carbon monoxide units is $20 to $70. The Silhouette line comes in hardwired units and features a sealed, self-charging lithium battery that lasts for the life of the unit. The units can interconnect with other units and retail for about $60. Kidde also offers combo units, which have a smoke detector feature in addition to the carbon monoxide detector.

Kidde also carries the Intelligent alarm (not tested), which uses one device to detect fast flaming and smouldering fires and carbon monoxide. A voice warning is issued based on what danger is detected. CO alarms are sold in home improvement stores, including Home Depot and Lowes,  at Sears, and at food and drug stores.

Smoke alarm prices range from $10 to $70. Kidde makes dual sensor units that use ionization and photoelectric technologies.

Comment:
I bought this Kidde brand in 2007. An electrician installed it. The Kidde smoke alarm has worked fine for me. After six years, I will have to replace it due to the red light flashing and chirping per the instructions. <br /><br />I would have preferred that it lasted much more but the warranty is for five years.
How long have you owned it:
More than six months
Bottom Line
Yes, I would recommend this to a friend.

Comment:
We have been repeatedly awakened in the middle of the night with the alarm screaming fire when there is none. This alarm was installed by an electrician and is not near any fuel burning appliance or other conditions thta would cause false alarms. It happened when it was new and now again 7 months later. Finally had to disconnect unit so can get some sleep.
How long have you owned it:
More than six months
Bottom Line
No, I would not recommend this to a friend.
