Product By Kidde(1 customers reviews)

Lowest Price : $53.00

Product Description

Direct Kidde Silhouette CO Alarm, Low Profile AC/DC Powered, Operates On A 120V Power Source With A Sealed Rechargeable Battery Backup, Innovative Low Profile Alarm Fits In Most Common Electrical 2-Gang & Plastic, Round Boxes With 3-1/2' Hole Spacing, Pre-Stripped Wiring Harness With Easy Off Cap Does Not Require Stripper Tool.

Amazon.com Product Description

No need to worry about faulty batteries with the Kidde KN-COPF-i Silhouette Low-Profile Carbon Monoxide Alarm. This no-maintenance alarm contains a rechargeable battery that runs off central electricity and lasts the lifetime of the unit. Dependable and easy to install, this alarm saves on labor and material costs over its lifetime. And because this alarm is interconnect-able, builders and do-it-yourself homeowners will quickly discover this is a must-have for remodels and new construction.
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.

Product Highlights Rechargeable battery eliminates replacement costs Discrete design protrudes less than an inch from ceiling Operates 40% longer than standard CO alarms Cost saving maintenance-free battery is ideal for high-density residencies Initiating alarm alerts emergency personnel with a flashing LED

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.

Easy-to-Install Alarm Features a Discreet Profile
The Silhouette alarm's faceplate protrudes less than an inch from the wall, making it the most discreet alarm on the market. The encasement containing the sensor and components fits in most standard 2-gang, metal or plastic electrical boxes.
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.

"Also makes a good night light" 2010-02-11
By Larry (Maryland)
The CO detector was installed several weeks ago, so it is really too early to know how it truly performs. I do like the small size and the low profile. It looks good compared to other CO detectors.As recommended, the detector was installed in the hallway just outside our bedroom. The display is incredibly bright. It is easy to read in the daytime and is probably sunlight readable. However, since we leave the bedroom door open, it lights up the entire bedroom at night. Now I wish I had installed it at the far end of the hallway just to reduce the light level.I did the test the CO detector and cross-test with a Silhouette smoke detector. The CO detector does alarm for fire and displays the word FIRE. The Silhouette smoke detector did not report for the CO test. It did not seem that the CO detector came out of test mode cleanly. It's not clear if I didn't do the test correctly or if the detector was stuck in a weird state. Later (and also after a power failure) everything seems normal.

Amazon.com Product Description

If you want to build an integrated smoke and carbon monoxide alarm system, but without the cost and hassle of retrofit wiring in your home, the ONELINK Combination Smoke Alarm and Carbon Monoxide Detector is an ideal choice. This alarm provides ultimate protection from two deadly threats, and it is packed with innovative features that give you precious time in the event of an emergency. And because it is able to wirelessly communicate with other ONELINK alarms, this device can help you create a whole-home safety network.

ONELINK's mesh network ensures you'll hear an alarm no matter where you are in the house.

The ONELINK Combination Smoke Alarm and Carbon Monoxide Detector At-a-Glance: Allows for wireless alarm interconnectivity. Dual smoke and carbon monoxide detection. Loud 85-dB siren plus talking alarm for safety. Photoelectric smoke sensor reduces false alarms. Two 'AA' batteries included.

Faster Notification for Faster Escape
In the event of a fire or carbon monoxide (CO) emergency, every second counts. Unfortunately, traditional battery-operated alarms can often cost you precious time. For example, if a fire starts in your basement while you're asleep upstairs, you may not hear the smoke alarm, and it may take several minutes before the heat and smoke reaches an alarm that's close enough for you to hear its siren.
Thankfully, the ONELINK Combination Smoke Alarm and Carbon Monoxide Detector is designed to provide you the earliest warning in an emergency. When this clever device detects smoke or carbon monoxide, all integrated ONELINK alarms in your home will together, increasing your chances of getting out safely.
Interconnectivity Without the Wires
Until now, alarms that could signal each other were only available in homes with hardwired systems. All ONELINK alarms, however, communicate with each other wirelessly through integrated radio frequency. This means that when one sounds, they all sound, providing a whole-home safety network.
If you already have an existing system of hardwired alarms, but you are looking for an update, simply replace one of the alarms with the ONELINK Combination Smoke Alarm and Carbon Monoxide Detector--your alarms will continue to be able to communicate with one another.
Talking Alarm Tells You Where the Danger Is
Not only do ONELINK wireless alarms talk to each other, but they also talk to you! Voice warning with location technology means that integrated ONELINK alarms will tell you where the danger is in your home with an actual programmable voice. For example, if there is fire in your basement, the alarm in your bedroom will speak 'Warning, evacuate. Smoke in basement." This feature will help you plan your escape method, so you can evacuate your family as safely as possible.
Accurate Technology Minimizes False Alarms
Utilizing environmentally friendly photoelectric technology to sense smoke, the ONELINK Combination Smoke Alarm and Carbon Monoxide Detector reduces the chance of false alarms caused by cooking or bathing.
Additionally, this alarm features an electrochemical CO sensor, which is the most accurate technology available for detecting CO.
Designed for Safety and Ease of Use
As user-friendly as it is effective, the ONELINK has a dual-purpose button that silences the alarm and tests the system's function. And because the device emits a loud 85-dB siren, you'll be sure to hear it, even if you're asleep or in the shower. The audible low-battery signal can be muted for up to eight hours (so as not to disturb your sleep).
As safe as it is easy to use, this ONELINK device is FCC compliant for wireless device standards, and it meets UL217 and UL2034 standards for combination CO and smoke alarms.
The ONELINK Combination Smoke Alarm and Carbon Monoxide Detector is backed by a five-year limited warranty.
What's in the Box
Combination Smoke Alarm and Carbon Monoxide Detector; two 'AA' batteries; and manual.
Technical Details

• Wireless enabled battery operated combination smoke and carbon monoxide alarm
• Interconnects with other First Alert ONELINK enabled alarms to create a wireless safety network

"Excellent smoke/CO detector" 2010-04-08
By John M. Leslie
I am satisfied with both the product and my dealings with Amazon. Both were excellent!

"Straightforward" 2010-01-02
By C. Richards (Pennsylvania)
These combined CO/smoke detectors install and set up very easily. Let's hope there will never be an opportunity to comment on their function.My only complaint is the blister pack was harder to open than most.

  
"Overpriced and barely usable" 2009-12-01
By Red Castle (NM)
One of the reasons this unit is expensive is because it is a combination CO detector and smoke detector.I would have preferred a CO detector alone because I already have a smoke detector.Another reason for the high price is the feature that allows it to communicate with other First Alert units.Since I only have one unit this feature is useless to me.First Alert does not offer a consumer friendly line of products.I also noticed that the packaging was covered in propaganda about the communication feature,but completely lacking any basic information about the specifications as a CO detector.It took three tries to get the unit installed because it kept going into some kind of fault mode and the electronic "voice" kept saying to check the instructions, which were no help. After attaching/detaching the unit and removing/inserting the batteries I finally got the unit to stay active.Every couple of weeks the unit still chirps about some kind of error and says to check the instructions,which are no help.The electronic "voice" is very hard to understand.The instruction sheet is the size of a table and cannot be easily folded for filing.The unit could not be registered due to a script/HTML error on the First Alert website.

On the plus side:

1. The included batteries were a name brand rather than something cheap from overseas.

2. The base had versatile mounting holes.

  
"I really like these, feels safe, but BATTERIES run out quickly" 2009-11-29
By Kathy
I have 4 of these smoke detectors installed in my cape cod home and it makes me feel safe. When one goes off, they all go off and the deep male voice says whether there is smoke or CO2 in the house. ONCE they went off when there was smoke in the kitchen. The rest of the time they go off, mostly in the middle of the night for some mysterious reason, saying, in the loud man's voice, "Change the batteries in the kitchen smoke detector" or "Change the batteries in the hallway smoke detector" etc etc. I currently have two of them lying on the floor with the battery drawers pulled out which stops the voice and the beep--beep--beep letting me know the batteries, which I had installed maybe 2 or 3 or 4 weeks before, are used up. The detectors are still lying on the floor days later because if I install new batteries then I will be woken up ever sooner by those batteries wearing out. Still I rate with 3 stars because these detectors make me feel safe. What's wrong with this picture? One is in sight laying on the floor as I type this. I use the brand and number of battery recommended by FirstAlert and I do not test the smoke detectors monthly because that would use up the batteries even more quickly.

"Good Product, but Eats Batteries!" 2009-11-20
By F. E. Smith (northern Illinois)
I purchased three of these when they first came out--quite a few years ago--based on a Consumer Reports evaluation. I love the idea, and they were very easy to set up. We've never had one go off in an emergency, but we have been awakened a lot because the batteries have run down and we get a loud warning. The first couple times it's really heart stopping to hear an amplified voice shouting outside your bedroom. The main unit goes through batteries as often as every two weeks. Although, sometimes the batteries will last for many months. Since I always buy top end batteries with distant expiration dates, this makes no sense. Because the battery tray slides out at an odd angle, the finger-hole used to pull it out is smaller than a finger, and the plastic binds on itself, changing the battery of a device that's shouting at you in the middle of the night is no simple task. Since they are so expensive but seem to work well, I'm not sure if I want to replace them, get rid of them, or just keep burning through batteries. I know for sure that my wife is really annoyed.

About CO Poisoning and Home Fires
Carbon monoxide (CO), also known as the "silent killer" because it's odorless, tasteless, and invisible, is the leading cause of accidental poisoning deaths in North America. Additionally, every year, 70 percent of all home-fire deaths occur in homes with no alarms or no working alarms, while nearly one quarter of smoke alarms in reported fires are not working. Both the KN-COB-B CO Alarm and the i9060 Smoke Alarm provide lifesaving warnings to allow you to get out of the house before you are exposed to dangerous levels of CO, or trapped by fire or smoke. They also feature user-friendly designs that make it simple to ensure everything is functioning properly. No home should be without them.
CO Alarm Utilizes Advanced Technology to Detect CO Levels
The Kidde KN-COB-B battery-operated carbon monoxide alarm utilizes sophisticated electronic components to protect you and your family from the dangers of carbon monoxide. Suitable for all living spaces and featuring a seven-year life, this alarm includes a snap-on cover that gives immediate access to the batteries for fast changes. Also that the battery lockout system makes it difficult to close the cover without the batteries being installed correctly, giving you peace of mind that the unit is working properly.
Flashing LEDs and Alarm
The KN-COB-B provides continual monitoring of CO levels in your home. Its green LED will flash every 30 seconds to show that it's functioning properly. Should it detect elevated CO levels, its red LED will pulse, and a clearly audible alarm pattern will sound until the device is reset or the CO is eliminated. In addition, a test/reset button allows you to test that the alarm is functioning properly.
Ionization Sensor Technology
Powered by a 9-volt battery, the i9060 is a stand-alone smoke alarm with an ionization sensor. Ionization sensing alarms may detect invisible fire particles (associated with fast flaming fires) sooner than photoelectric alarms. Photoelectric sensing alarms may detect visible fire particles (associated with slow 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 fires that can occur within the home.
The i9060 also offers the convenience of a hush feature that temporarily silences nuisance alarms--a great feature for kitchen alarms.
Compliancy and Warranty Information
These Kidde alarms are both UL-listed. The KN-COB-B Alarm backed by a five-year limited warranty, and the i9060 Smoke Alarm is backed by a 10-year limited warranty.

"Too sensitive?" 2009-12-11
By Shannon (Maine, USA)
Mine could be a dud, but I've had this smoke detector for a couple of months ago and I've noticed that it seems super sensitive. I can't heat my oven above 400 degrees without it going off (and yes, my oven is clean). I need to take it down and move it into the other room whenever I cook. I guess the bright side is I know it works.

  
"Good price on combo pack" 2009-11-30
By TarHeel Jim (NoVa)
Note: You get 1 smoke detector and 1 CO detector in the pack. I read the description as each unit does both. (I didn't read closely!) But Kidde makes good detectors and this is still a very good deal.

First Alert SC9120B Hardwire Combination Smoke/Carbon Monoxide Alarm with Battery Backup

Product By BRK Brands(23 customers reviews)

Lowest Price : $31.49

Product Description
The BRK hardwire combination smoke and carbon monoxide alarm detects two hazards with one simple unit. Carbon monoxide (CO) is a colorless, odorless, deadly gas. It can be emitted by sources including gas or oil furnaces, gas clothes dryers, water heaters, fireplaces, wood stoves, charcoal grills, gas ranges, and space heaters. A clogged chimney, improper venting, and attached garages can also cause carbon monoxide accumulation. According to the Consumer Product Safety Commission (CPSC), at least one CO alarm should be installed near a home's sleeping area.
The BRK SC9120 hardwire combination smoke and CO alarm with battery backup includes these features:

• Quick plug-in power connector for easy installation.
• 120-volt AC inter-connectable (with maximum 18 compatible devices). The alarm can be interconnected with up to 12 other compatible smoke alarms and six compatible devices like bells, horns, repeaters and door closers. If one unit triggers an alarm, all smoke alarms in the series will sound. Power indicators show which unit in the series initiated the alarm.
• Ionization sensor which is more effective at detecting flaming fires which consume combustible materials rapidly and spread quickly.
• Microprocessor controlled for fewer nuisance alarms.
• Single test/silence button which both silences a non-threatening alarm or low battery warning and allows you to test the unit's functionality.
• Automatically performs internal test of functionality.
• Latching alarm indicator which automatically identifies which unit initiated the alarm.
• Separate smoke and carbon monoxide visual and audible warnings.
• Battery drawer lock and mounting bracket lock for tamper resistance.
• AC power indicator and alarm indicator light.

"Worked for a while, then..." 2010-08-19
By B. Johnsen
This unit worked reliably for a year, then started to go off, on it's own, in the middle of the night. Consistently, in the middle of the night. After a couple of weeks of troubleshooting, and waking up my two toddlers, I'm replacing with a different brand. All the other units in the house still work reliably, and have detected even trace amounts of smoke. Maybe I just got a bad one?

"Happy with purchase" 2010-08-03

About Carbon Monoxide: The Silent Killer
The leading cause of accidental poisoning deaths in North America, carbon monoxide (CO) is often referred to as the silent killer because it's odorless, tasteless, and invisible. 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, CO poisoning can often go undiagnosed.
When placed on every level of your home, alarms like the Nighthawk 900-0234 can help protect everyone in the house from CO exposure by giving an unmistakable audible signal when CO levels have reached an unhealthy point.
Easy-to-Read Digital Display Shows CO Levels
Featuring a small, sleek, discreet design that's suitable for all living areas, the Nighthawk 900-0234 is preferred among CO alarms because of its digital display. This display clearly shows current levels of CO--from 30 to 999 ppm--and it updates every 15 seconds, giving you an indication of any abrupt changes or alarming trends. The display also shows the peak CO level recorded by the alarm since it was last reset or unplugged.
Loud Alerts Signal Elevated Levels and Low Battery Life
The Nighthawk 900-0234 immediately sounds a loud warning signal if CO has reached an elevated, unsafe level in your home, giving you plenty of time to leave the premises. You'll also hear a clearly audible alert when the product is nearing the end of its seven-year life, or the battery needs changing.
Battery Operated for Continuous Monitoring
For added convenience, the Nighthawk 900-0234 also has a battery backup, which means you won't have to worry about power outages. Unlike many A/C units, the Nighthawk will monitor continuously without interruptions. And because it has a seven-year product life, it's able to provide protection up to 40 percent longer than other units.
User-Friendly, Protective Features
For added peace of mind, the Nighthawk 900-0234 has a test/reset button that allows you to verify that the alarm is functioning properly, and a tamper-resistant feature that works by putting the unit into constant alarm mode if it has been unplugged or has come loose from the outlet.
Compliancy and Warranty Information
The Nighthawk 900-0234 is UL listed and is backed by a seven-year limited warranty.

"Defective" 2010-09-22
By Robert
For no particular reason, every several days the alarm would read "error" and start beeping. No, it wasn't near any source of combustion, open windows or cooking. You can only reset it so many times before realizing that you simply can't live with something like that. Out with the trash.

"No problems after 6 months" 2010-07-23
By G. Ware (Colorado USA)
I have had this unit in our bedroom for over 6 months with no issues. No false alarms and no backup batter issues, it just works or at least the display tells me so. I do like the display on these units rather then just a status light like other lower priced models. If you are looking for a higher quality carbon monoxide detector then I would sure take a look at this unit. I have had other Kidde Nighthawks with no problems as well. Just remember that after a number of years all detectors are no longer good and need to be replaced.

"Waste of money" 2010-07-18
By EEMueller
I purchased this unit as a backup to the gas and CO detectors that are wired into my central alarm system. In the 5 months that I've had this unit installed, it has false alarmed 4 times, each time indicating explosive gas. The last one was last night with a house full of guests. The other detector sensed nothing, and after reading some reviews, I found this type of failure with Kidde alarms is very common. This beauty is headed straight for the trash.

  
"good CO detector, like the digital display and battery-backup" 2010-07-11

Both 2 of these to replace my 7-year-old Kidde CO detectors of a similar model, one per floor. They plug into any wall outet. I like the battery-backup and the digital CO level display. If you press a button, you can see "peak" CO level since the last reset. Am using these peak level readings to try to track down occasional very low levels of CO that are too low to be dangerous or trigger any alarm. I am pleased with these CO detectors. My only complaint is that I wish I could see the instantaneous low level CO readings [but such pro CO detectors normally cost much more].One important point. There is something you have to do to prevent the unit from beeping every minute on battery backup if the AC power goes out. Follow the instructions to do that and you will like this unit much better as a result.

This is the first carbon monoxide detector I have ever purchased so I don't have any other experiences to compare it to. I've had it for a week and it seems to be working just fine. I really like the digital display that indicates "0" so I know that there is no carbon monoxide at all in the home. I'm assuming this is an accurate reading. (Hopefully!). It does seem like it is a quality product. I did use the test option to see if that worked and it did exactly what it was supposed to do.I did take one star off because of the ear-splitting noise you have to deal with when you put the battery in and also if you unplug the thing from the wall. I nearly jumped out of my skin! As soon as you install the battery---Be prepared for the noise!! You will want to hold the button in the back---walk it over to the wall--and plug it in immediately.I would recommend this product.
