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:
Unit seems to function fine. Never had an alarm and the battery is easy to replace when required. My primary issue with the device is the internal timer that causes the unit to stop functioning after 7 years and issues a nuisance alarm that you must now go purchase a new unit.

Comment:
I always thought these things were just another thing to buy for the house... best purchase I ever made... saved my family from a gas leak in our furnace. We could not smell the gas much... We called the gas and electric company and immediately vacated the house. Furnace had a gas leak... we never would have known if not warned by our Sept 2006 detector. The detector just went bad this week... buying the same one.
