Protect yourself and your family from the potentially deadly effects of carbon monoxide with the First Alert CO605 Plug-In Carbon Monoxide Alarm with Battery Backup. This easy-to-install, UL-listed alarm features advanced technology, a user-friendly design, and backup battery power to provide continual monitoring of carbon monoxide levels. It also comes complete with an "Alarm Action" chart that instructs you on what to do if the alarm sounds.

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 CO605--installed near sleeping areas. An alarm like the CO605 can detect the CO you can't see, smell, or taste before it causes any physical harm to you or your family.

Electrochemical Technology for Accuracy and Longer Life
The CO605 uses an electrochemical carbon monoxide sensor--the most accurate CO sensor available. In comparison to more commonly available technologies, electrochemical technology is highly accurate, requires a lower amount of power, and boasts a longer life. If the CO605's sensor detects a high concentration of CO, the unit will sound a clear, loud, 85-decibel alarm, giving you a chance to either ventilate the area or safely evacuate.

A/C Power with Battery Backup and User-Friendly Design
This unit runs on A/C power, but in case of an electrical outage, it will switch to battery operation. This gives you peace of mind during storms--when you're more likely to use generators that could potentially give off dangerous levels of CO.

For added convenience, installation is a snap. Simply plug the CO605 into any wall outlet--with no additional mounting--and it's ready to go. The unit features two 'AA' batteries to provide backup power to the monitor in the case of power disruption or outage.

Operation is equally trouble free. One button clearly labeled "Test/Silence" lets you test the unit to see if it's running properly or silence it during a false alarm.

Continually Monitors Both CO Levels and Battery Power
To give you real peace of mind, the CO605 continually monitors CO and re-alarms if dangerous levels persist. At the same time, a low-battery signal let's you know when it's time to replace the backup batteries (included); a low-battery mute quiets the signal for up to eight hours. An easy, front-open compartment allows for easy battery changes without dismounting the alarm, and an end-of-life chirp lets you know when it's time to replace the unit.

The CO605 comes with two 'AA' batteries and a five-year limited warranty. It also comes complete with an "Alarm Action" chart that instructs you on what to do if the alarm sounds.

What's in the Box
Carbon monoxide alarm, two 'AA' batteries, and user's manual complete with "Alarm Action" chart.

First Alert Smoke Detector and Carbon Monoxide Detector Alarm | Battery Operated, SCO5CN

Model: SCO5CN   |    Mpn: SCO5CN   |    Ean: 0029054856920   |    PartNumber: SCO5CN   |   Asin: B000MXJ498

The First Alert SCO5CN Combination Smoke and Carbon Monoxide Alarm features dual sensors to detect both smoke and carbon monoxide in a single device. A photoelectric sensor detects the smoke most often produced by smoldering fires, and minimizes false alarms from cooking smoke or shower steam. Additionally, the advanced electrochemical CO sensor detects carbon monoxide leaks from multiple sources, such as faulty fuel-burning appliances, blocked chimneys, and generators running inside or too close to homes. A loud, 85-decibel siren alerts you to the threat; unique alarm sounds and indicator lights on its face distinguish a smoke warning from a carbon monoxide warning. This carbon monoxide and smoke detector is battery operated, so you don't need an electrician for installation. Requiring just two AA batteries and featuring an easy-access battery compartment for quick changes, this smoke and carbon monoxide detector has a single button that allows you to silence a false alarm or test the unit. If your carbon monoxide alarm keeps chirping, the battery may be low or weak. On First Alert carbon monoxide detectors, check to see if the battery light is yellow or green. If the alarm is chirping and the light is yellow, it means the battery is low. The way to get a carbon monoxide alarm to stop chirping is to replace the battery.

Carbon monoxide (CO) is the leading cause of accidental poisoning deaths in America, yet many people don't know they are suffering from CO poisoning until its too late. Since symptoms of CO poisoning are like the flu, you might not even know you're in danger at first. That's why a carbon monoxide alarm is an excellent way to protect your family. It can detect the CO you can't see, smell or taste in the air. The First Alert SCO5CN carbon monoxide and smoke alarm uses an electrochemical carbon monoxide sensor-the most accurate technology available. The alarm uses photoelectric smoke sensing technology which is environmentally friendlier and which reduces nuisance alarms, making it ideal for cooking areas. It is also great for sensing slow smoldering fires quickly. The permanent sensors last the lifetime of the alarm. The test/silence button both silences a non-threatening alarm or low battery warning and allows you to test the unit's functionality. A low battery signal alerts you to replace the battery and end-of-life alarm of three chirps alerts you to replace the unit. Two AA batteries are included. 5-year limited warranty. UL listed. Not available for sale in Massachusetts. --Bree Norlander

First Alert Smoke Detector Alarm | Hardwired with Backup Battery, BRK9120b6CP

Model: 9120B   |    Mpn: 9120BFF   |    Ean: 0696505167234   |    PartNumber: 9120BFF   |   Asin: B00O8MVW3U

This First Alert hardwired smoke alarm includes a 9-volt battery backup that continues to protect you in the event of a power failure. The detector features an ionization sensor for detection of smoke and fast-flaming fires, as well as a loud, 85-decibel alarm. One button silences any nuisance alarms, and also tests detector functions, while lights indicate if the alarm detects smoke. The latching alarm indicator automatically identifies which unit initiated the alarm, even after the conditions that set off the alarm have subsided. And an end-of-life signal enhances your safety by letting you know when it's time to replace the unit. Connect it to compatible BRK or First Alert alarms within a single-family residence. When one alarm is triggered, all connected alarms will sound. There are generally two types of smoke alarms - ionization smoke alarms and photoelectric smoke alarms. Smoke particles of a varying number and size are produced in all fires. Ionization smoke alarms are generally more sensitive than photoelectric smoke alarms at sensing small particles, which tend to be produced in greater amounts by hot, flaming fires, that are consuming combustible materials rapidly and may spread quickly. Sources of these fires may include paper burning in a wastebasket, or a grease fire in the kitchen. Photoelectric smoke alarms are generally more sensitive than ionization smoke detectors at sensing large smoke particles, which tend to be produced in greater amounts by smoldering fires, which may smolder for hours before bursting into flame. Sources of these fires may include cigarettes burning in couches or bedding. For maximum protection, use both types of technology, such as in the Dual Sensor Smoke Alarm, on each level and in every bedroom of your home.

Kidde Hardwire Combination Smoke/Carbon Monoxide Detector Alarm with Battery Backup and Voice Warning, Interconnectable | Model KN-COSM-IBA

Model: 21026041   |    Mpn: 21026041   |    Ean: 0047871260416   |    PartNumber: 21026041   |   Asin: B00PC5RQPA

This combination smoke/CO alarm features an 85dB horn and voice that announces "Fire", "Carbon Monoxide", and "Low Battery" warnings when detected. It can also interface with other Kidde interconnectable alarms. Meets NFPA 72 standards Smoke and Carbon Monoxide Alarm

Protects from two different hazards, smoke and carbon monoxide (view larger). The KN-COSM-IBA combines a Carbon Monoxide and Ionization Smoke Alarm, providing two important safety devices in a single unit. This alarm includes a voice warning system that helps eliminate confusion, as it tells you if its detected fire or carbon monoxide, or even if it needs a new battery. This alarm has 2 AA battery backup, which protects you and your family even during a power outage when many incidences occur. The alarm also allows you to easily silence nuisance alarms using its convenient Smart Hush feature.

This talking combo alarm is powered by your home's electricity and can interconnect with other smoke alarms in your home. Experts recommend interconnected alarms, because when one sounds, they all sound, providing an early warning against fire by dramatically increasing your ability to hear an alarm anywhere in your home, regardless of where the fire starts.

Provides the recommended protection of an interconnected system. When one alarm goes off, they all do (view larger). Combination Smoke/CO Alarm for Improved Safety The Kidde Combination Carbon Monoxide & Smoke Alarm includes a voice warning system that eliminates confusion and clearly warns you and your family of a smoke or carbon monoxide danger, or if your battery is in need of replacement or your alarm is in hush mode.

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 pattern until smoke is eliminated.

Carbon Monoxide: Four short alarm beeps followed by a verbal warning "Warning! Carbon Monoxide!" This continues until the unit is reset or CO is eliminated.

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 accompanied by the chirp sound. The low battery warning will only sound once every fifteen minutes.

Voice Hush Indication: "Hush Activated" and "Hush Cancelled" 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.

Inter-connectable for Improved Safety Fire and consumer experts recommend interconnected alarms for added protection. According to the National Fire Protection Association (NFPA), most Americans feel they are more at risk of being a victim of a tornado than of a house fire. Actually the opposite is true. Fires are more common than any other disaster that strikes a family at home, and can become deadly in minutes.

You have on average less than three minutes from the time you hear a smoke alarm to escape a fire. The sooner you hear an alarm, the sooner you can get out safely. Smoke alarms that link together so that when one goes off, they all go off, are called interconnected alarms. These alarms provide more warnings in more places, giving your family more time to escape a house fire. Houses built after 1993 are required by building codes to have interconnected alarms that are wired into their electrical system.

KN-COSM-IBA Hardwire Combination Carbon Monoxide and Smoke Alarm At a Glance Talking alarm announces the hazard type detected, helping to speed up reaction time Employs both smoke and carbon monoxide sensors Inter-connectable to provide improved protection Features a hush button to silence the alarm for non-emergency situations like a smoky dinner Battery safeguard ensures the unit cannot be accidentally mounted without batteries
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 ten 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 AA Battery Backup, Indicator LED, Test Feature, Low Battery and End-of-Life Warning The alarm's AA battery backup 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.

Ten 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.

When placed on every level of your home, alarms like the KN-COPP-3 Nighthawk can help protect everyone in the house from CO exposure by giving you an unmistakable signal when levels have reached an unhealthy point. If unhealthy levels are detected, the alarm will emit four quick audible beats every five seconds until either levels decrease or the reset button is pressed. Easy-to-Read Digital Display Shows CO Levels
The KN-COPP-3 Nighthawk is unique among traditional CO alarms because of its digital display.

First Alert Carbon Monoxide Detector| No Outlet Required, Battery Operated, CO400

Model: CO400FF   |    Mpn: CO400   |    Ean: 0736569087649   |    PartNumber: CO400   |   Asin: B000N8OYXI

The First Alert CO400 Carbon Monoxide Alarm utilizes an electrochemical carbon monoxide sensor to monitor your space for a carbon monoxide threat. The battery-powered design doesn't require an electrician; simply insert the included 9-volt battery, and the carbon monoxide detector is ready to go. The advanced electrochemical CO sensor detects carbon monoxide leaks from multiple sources, such as faulty fuel-burning appliances, blocked chimneys, and generators running inside or too close to homes. When CO levels become elevated, a loud 85-decibel alarm alerts you to the threat. Because CO evenly distributes itself, it's important to have a CO detector on every level and in every bedroom of your home. Designed to be simple to use, the CO detector has just one button that silences or tests the unit, as well as an end-of-life timer that lets you know when it's time to replace the device.

Carbon monoxide (CO) is the leading cause of accidental poisoning deaths in America, yet many people don't know they are suffering from CO poisoning until its too late. Since symptoms of CO poisoning are like the flu, you might not even know you're in danger at first. That's why a carbon monoxide alarm is an excellent way to protect your family. It can detect the CO you can't see, smell or taste in the air. The First Alert CO400 carbon monoxide alarm uses an electrochemical carbon monoxide sensor-the most accurate technology available. The permanent sensor lasts up to five years. It is powered by on 9V replaceable battery giving you peace of mind even during power outages. The test/silence button both silences the alarm and allows you to test its functionality. The unit monitors and re-alarms if carbon monoxide levels persist sounding a loud 85-decibel horn. No installation is required and the attractive design allows the unit to be placed anywhere you need it. It includes an optional wall mount with no outlet required. An audible and visual low battery signal alerts you to replace the battery. Pull down action chart has convenient guide on what to do if an alarm sounds. 5 year limited warranty.

Carbon monoxide poisoning can come about via a number of sources, including everyday items and appliances in your home or office. And because symptoms of CO poisoning mimic the flu or other common illnesses it can often go undiagnosed.

Audible Alarm Pattern Alerts you to Elevated CO and Gas Levels
When placed on every level of your home, alarms like the KN-COEG-3 Nighthawk can help protect everyone in the house by giving you an unmistakable signal when gas levels have reached an unhealthy point. If unhealthy levels of CO are detected, the alarm will emit four quick audible beeps every five seconds until either levels decrease or the reset button is pressed. If methane gas or propane gas is detected, the alarm will emit beeps every other second with "GAS" shown in the display.

The MC4000 MultiSensor is a high-performance, low-cost way to monitor and protect an apartment or condo, a second home, remote buildings, RV, car, or boat. You can set alerts so you and up to 11 other people are notified when an alarming condition occurs, such as extreme temperature or humidity, power loss, or water on a floor. The MC4000 has an integrated cellular modem, backup battery, and $5/month cell/cloud plan to provide a powerful, flexible and portable way to protect your property. The MC4000 can be a primary monitoring device and can also back up other systems that rely upon electrical power, fixed broadband connection or a phone line.

Applications include: Temperature - to help prevent frozen water pipes and safeguard pets or equipment; Humidity - to guard against mold that can damage your home or health; Water leaks - to detect water on the floor when a pipe, water heater, or sump pump breaks; Power loss - to monitor an electrical outlet, and alert you when power is lost; Light level - to track a change in light intensity, showing for instance that an elder did not turn on a light when expected, or a storage area light came on; Acceleration - to sense earth tremors or equipment movement. A remote water (flood) sensor is provided with a five-foot cord. The MultiSensor comes with secure Internet storage where a 90-day history of sensor readings is maintained. The privacy and security of your monitored location is secured by cellular encryption, a unique X.509 certificate and TLS. The Motorola MC4000 comes with a 2-year warranty, and a 1-year warranty on the lithium-ion battery. Experienced USA-based customer support specialists are ready to help if you need them.
