Kidde Smoke Detector with HUSH (3 Pack) Review
First Alert CO615 Carbon Monoxide Plug-In Alarm with Battery Backup and Digital Display Review
The First Alert CO615 carbon monoxide alarm uses an electrochemical carbon monoxide sensor-the most accurate technology available. Installation is as simple as plugging it in to any wall outlet. Its easy-to-read backlit digital LED display gives you a clear read-out of current CO concentrations in parts per million. The alarm includes a battery back-up giving you peace of mind in a power outage. The test/silence button both silences a non-threatening alarm or low battery warning and allows you to test the unit's functionality. The unit monitors and re-alarms if carbon monoxide levels persist sounding a loud 85-decibel horn. An audible and visual low battery signal alerts you to replace the battery and an indicator alerts you when a battery has been removed. An end-of-life alarm of three chirps alerts you to replace the unit. Two AA batteries are included. 5-year limited warranty. UL listed. --Bree Norlander

Kidde KN-COSM-B Battery-Operated Combination Carbon Monoxide and Smoke Alarm with Talking Alarm Review
This alarm uses ionization sensing technology for the smoke alarm. Ionization sensing alarms may detect invisible 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.

Alarm Warnings
Fire: The red LED will flash and be accompanied by three long alarm beeps followed by a verbal warning message "Fire! Fire!" The alarm will repeat the pattern until smoke is eliminated. View movie showing voice warning
Carbon Monoxide: Four short alarm beeps followed by a verbal warning "Warning! Carbon Monoxide!" This continues until the unit is reset or the CO is eliminated. View movie showing voice warning
Low Battery: One chirp followed by warning "Low Battery." The red LED light will flash. This pattern will continue every minute for the first hour. After the first hour, the red LED light will flash once every minute and will be accompanied by the chirp sound. The "Low Battery" warning will only sound once every fifteen minutes.
Voice Hush Indication: "Hush Activated" and "Hush Canceled" voice announcement.
Peak Level Memory: If the alarm had detected a CO level of 100ppm or higher when the Test/Reset button is pressed, the unit will announce "Carbon Monoxide Previously Detected" to warn of the CO incident.
Trademarked Hush Feature for Convenience
By pressing the Hush button, you can easily and safely silence nuisance alarms caused by non-emergency situations, such as overcooked dinners.
This feature desensitizes the alarm for approximately 10 minutes. If the smoke is not too dense, the alarm will silence immediately, the unit will verbally announce "Hush Mode Activated", and the green LED will flash every 2 seconds for approximately 10 minutes.
Reliable Battery Power, Indicator LED, Test Feature and Low-Battery Warning
The battery powered alarm provides continuous protection, even during power outages. Because this alarm only helps protect you if it's working, this unit features a red LED that flashes every 30 to 40 seconds to indicate that it is operating correctly. For additional peace of mind, the alarm also contains a test/reset button that enables you to periodically test its circuitry and horn.
If any form of battery failure is detected the red LED light will flash and the unit will "chirp" one time, followed by the warning message "Low Battery." This cycle will occur once every minute, and will continue for at least seven days.
Seven (7) years after initial power up, this unit will "chirp" every 30 seconds. This is an "operational end of life" feature which will indicate that it is time to replace the alarm. UL 2034, the independent standard applicable to CO alarms, requires CO alarms to have an end of life warning. This requirement went into effect in March 2007, meaning any CO alarm manufactured after April 2007 with a UL listing must have this feature. Most states that require CO alarms in residential dwellings mandate that the alarm meet the UL 2034 standard.
The unit measures just 5.75 inches in diameter and 1.7 inches deep, and it features a neutral, white finish. It includes tamper resist features to deter vandalism or theft. This combination smoke/CO alarm is UL listed, so you can be confident of its quality, and it is backed by a 5-year limited warranty.

 Where does carbon monoxide come from? |
For example, if a high level of CO is detected in your kitchen, you'll hear a clear message saying, "Warning: evacuate. Carbon monoxide in kitchen. Evacuate." You'll also hear a loud, 85-decibel alarm and see a flashing red LED that clearly indicates the nature of the threat. Together, these audible and visible signals let you know precisely where the danger is, so you can plan the safest possible escape route. This extra level of protection is something a standard alarm simply can't provide.
Powered by two 'AA' batteries (included), this alarm uses an electrochemical carbon monoxide sensor--the most accurate CO sensor available. It also uses photoelectric sensing technology, which provides optimal protection from smoldering fires and reduces false alarms like those caused by cooking smoke and shower steam. The SC07CN even stores CO readings and verbally communicates the highest level of CO detected, so you can easily discern patterns that indicate it's time to check your appliances or other combustible items for CO leaks.
For convenience, most household remote controls are compatible with this system, meaning you can quickly test or silence the alarm. Additionally, an alarm mute button silences unnecessary alarms and allows you to test alarm function. There's also a low-battery warning that indicates waning power--a low-battery mute quiets the low-battery signal for up to eight hours. Finally, an end-of-life alarm that tells you when it's time to replace the unit, and a side-access drawer makes for easy battery changes.This alarm comes with a five-year warranty.
Carbon Monoxide: The Leading Cause of Accidental Deaths in the U.S.
Carbon monoxide, an invisible, odorless gas, is the leading cause of accidental poisoning deaths in America, yet many people don't know they are suffering from CO poisoning until it's too late. Because you can't see, taste, or smell it, CO can kill you before you even know it's there. Likewise, exposure to low levels over time can make you ill.
The Consumer Product Safety Commission recommends that every home have at least one carbon monoxide alarm with an audible warning signal--like the SC07CN--installed near sleeping areas. An alarm like the SC07CN can detect the CO you can't see, smell, or taste before it causes any physical harm to you or your family.
Smoke Alarms Offer the Best Chance of Escaping Deadly Fires
Fire is a deadly threat to every household; it can strike anywhere, any time. The frightening truth is that in 2005, there were nearly 381,000 home fires in the U.S., resulting in over 16,000 casualties. Because of the very real threat of fire, it is vital that every household uses tools for fire protection. Smoke alarms like the SC07CN are the easiest, most cost-effective way to keep your family safe from fire. The more smoke alarms you have installed in your home, the more your safety increases.

Smoke Alarm - Dual Sensor - Detects Flaming and Smoldering Fires - Battery Operated - Kidde PI9000 Review
Kidde KN-COPF-i Silhouette Wire-in Low Profile Carbon Monoxide Alarm Review
Rechargeable Batteries Save Money, Time, and Labor
The Kidde Silhouette Low-Profile Carbon Monoxide Alarm features a rechargeable lithium-ion battery sealed inside the unit that recharges automatically via central electricity. If there is a power outage, the battery backup feature will allow continuous monitoring of carbon monoxide (CO) levels--something AC-only units can't offer--and it will recharge when electricity is restored.
Over the span of the alarm's life, this no-fuss unit saves homeowners money, time, and labor on battery changes. For builders, landlords, hoteliers, and apartment managers, this innovative feature cuts down on callbacks, material, and labor costs.
The battery is designed to last the lifetime of the alarm, approximately seven years, which is 40 percent longer than standard CO alarms. Once the alarm has reached the end of its life, it will chirp every 30 seconds, letting you know it's time for a replacement.

 Take a closer look at the Silhouette carbon monoxide alarm with installation photos. |
 An interconnected system provides more warnings in more places in case of fire or carbon monoxide in your home. |
Builders and do-it-yourselfers will appreciate the pre-stripped wiring harness, which eliminates the need for a stripper tool, and the tinned strands that increase conductivity and wire nut grip. Once the CO alarm is installed, simply make sure the unit receives AC power for 24 hours to fully charge the battery. A green LED indicates power is being delivered to the alarm, an amber LED light indicates the unit is initiating an alarm, and a red LED light indicates the unit is in alarm mode.
Interconnect-able System Offers Early Hazard Detection
This alarm uses advanced electrochemical CO sensing technology, providing reliable protection against the dangers of carbon monoxide. In addition, the unit is designed to interconnect with other Kidde CO and smoke alarms, providing you with the earliest warning of a CO or fire hazard. The Digital Display feature allows for easy viewing of carbon monoxide levels from 30 - 999 parts per million. Each alarm in the interconnect-able system is equipped with an initiating alarm memory. In the event of an emergency, the alarm that first detects a hazard will feature a flashing LED, allowing emergency personnel to locate the source quickly and efficiently. All other alarms in the system will sound, however, their LEDs will not flash. This feature is especially useful in apartment buildings, condominiums, hotels, and dormitories.
Meets Industry Standards
Like all Kidde alarms, the Silhouette Low-Profile alarm has been approved by the Underwriters Laboratories (UL), an independent third-party testing laboratory that sets the industry standard for alarms.
