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:
Bought this Carbon Monoxide Detector from [@] seven years ago on the recommendation from Consumer Reports. It has worked flawlessly, even alerting me when a worker left his truck running and filled our home with Carbon Monoxide while I was napping. On the downside, Kidde has an end of life signal that goes into effect after seven years rendering the unit inoperable and requiring replacing. I don't know if that's such a great idea since it ends up in a landfill somewhere. Oh well, off to the home improvement store. I'll probably get the same brand and model.
How long have you owned it:
More than six months
Bottom Line
Yes, I would recommend this to a friend.

A Great Combo Unit
09/23/2008
Strength
Ideal for the furnace room, where two big threats are a CO leak or a natural gas leak. AC/Battery operation means you can pretty much ignore it most of the time.
Weakness
Paint fumes will trigger a gas alarm.There is no indication that the plug is out and it is running on battery.After 6 years, the thing failed by repeatedly triggering a gas alarm.
I had this unit for over six years and never had a battery problem. I'm not sure why the previous rater's alarm ate batteries so often. I replaced them once a year, even though it didn't need it. The unit will automatically switch to battery without *any* indication if the AC goes out. Perhaps he had a power problem, or maybe just a bad unit. I simply replaced the battery once a year, along with my smoke detector's battery.After 6 years, it finally failed (by repeatedly claiming a gas leak) and I'm going to buy another one.

Strength
Bought it for Digital readout.
Weakness
SHOULDN'T require a Battery Back up if you do not care to use this feature. Made it virtually worthless.
Maybe mine is junk , I do not know, but seeing the other guys review, it must be correct. I even had NEW batteries that would set this stupid thing off, if you try to use it without batteries, it will keep Beeping and beeping and beeping and if you use batteries, it still beeps, completely worthless. A waste of money.

This Model Eats Battery
01/08/2007
Strength
I Bet The Battery Manufactures Love This Model
Weakness
Batteries Last 3 - 5 Weeks
Unless you're really bored and have lots of money for batteries, DO NOT BUY THIS MODEL. Of course the battery always seems to die in the middle of the night which turns the alarm on. Not a nice sound to wake up to. I would suggest buying a model without the battery backup.
