Unfortunately, conventional battery-operated alarms can normally expense you precious time. For example, if a fire starts in your basement when you are asleep upstairs, you might not hear the smoke alarm, and it may possibly take numerous minutes ahead of the heat and smoke reaches an alarm that is close sufficient for you to hear its siren.
Thankfully, the ONELINK Combination Smoke Alarm and Carbon Monoxide Detector is developed to give you the earliest warning in an emergency. When this clever device detects smoke or carbon monoxide, all integrated ONELINK alarms in your property will together, growing your probabilities of acquiring out safely.
Interconnectivity With out the WiresUntil now, alarms that could signal each other had been only available in properties with hardwired systems. All ONELINK alarms, still, communicate with each and every other wirelessly through integrated radio frequency. This means that when one particular sounds, they all sound, supplying a complete-house safety network.
If you currently have an current technique of hardwired alarms, but you are seeking for an update, basically replace 1 of the alarms with the ONELINK Combination Smoke Alarm and Carbon Monoxide Detector--your alarms will continue to be able to communicate with one particular yet another.
Talking Alarm Tells You Where the Danger IsNot only do ONELINK wireless alarms speak to each and every other, but they also talk to you! Voice warning with place technologies implies that integrated ONELINK alarms will tell you exactly where the danger is in your household 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 function will aid you program your escape method, so you can evacuate your family members as safely as doable.
Accurate Technologies Minimizes False AlarmsUtilizing photoelectric technology to sense smoke, the ONELINK Combination Smoke Alarm and Carbon Monoxide Detector reduces the chance of false alarms triggered by cooking or bathing.
Additionally, this alarm features an electrochemical CO sensor, which is the most accurate technologies readily available for detecting CO.
Developed for Safety and Ease of UseAs user-friendly as it is helpful, the ONELINK has a dual-objective button that silences the alarm and tests the system's function. And simply because the device emits a loud 85-dB siren, you will be sure to hear it, even if you are 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 secure as it is straightforward 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.

Customer Reviews

Pros: Peace of mind connecting basement sensors to attic bedroom, battery life, easy maintenance, easy setup, spoken alarm identifies threat and location and level of Carbon Monoxide at all networked units.
Cons: Price
We have a four-level home. All the carbon monoxide(CO) and fire sources are in the basement or on the first level: A gas furnace, hot water heater, and clothes dryer in the basement, a fireplace on the first floor. We keep the basement door closed and we sleep in bedrooms on the 2nd and 3rd floors, often with doors closed.
Conventional smoke detectors can be fairly hard to hear when that far away and it is also something of a guessing game which one is going off and why.
So two of these units (one for the basement and one for the 2nd floor hallway) address several unique challenges: First, would a detector in the basement ever awake us upper-floor sleepers in time? Second, with a total of 4 detectors in the house, how much time would you waste trying to identify the location and nature of any problem?
While expensive, their cost is the only downside I've experienced in a year and a half of ownership and two of these units are really the best way to install networked CO and fire detectors in a tall house.
These do require setup beyond just putting batteries and mounting, but it was easy considering that each unit must have a spoken location associated with it so that the spoken alarm can explain things like "Warning. Carbon Monoxied detected in Basement" or "Warning. Smoke detected in Hallway".
Note that when one unit detects trouble (or is being tested), the other speaks what the problem is too. Also during tests the unit reports the maximum CO level detected since the last test. This means that if something goes wrong in the basement, we'll get the message in right outside our bedrooms.
Replacing batteries is easy: they come in a little slide out tray and they seem to last longer than 9V batteries do in my older detectors.
I'm back today to order a 3rd unit to place in the Attic so that we can replace an un-networked smoke-only detector there also detect CO near the chimney (in case it ever leaks or drafts) as it passes through.

Smoke and Carbon Monoxide detectors/alarms are extremely important for every home. People hate to spend the money on them, especially the higher quality (more expensive) detectors, and yet your very life can depend on them. There are many choices on the market today, ranging from cheap, basic models to extremely expensive, high-tech devices. There are two main types of smoke detectors: ionization detectors and photoelectric detectors. Most detectors utilize either one or the other of these technologies while some use both. Most detectors just use a beep-style audible alarm, while some talk, some have strobe lights, and some have a bright light to illuminate a dark area. Many detectors today are combining a smoke and carbon monoxide sensor, so you have dual protection in a single device. You can choose between AC and battery operated devices. Most (if not all) new homes are built with AC detectors in all of the vital areas, which usually contain a battery backup in case of a power outage. Many of these new detectors, installed in new homes, are linked together so that one detector will trigger all of them to sound their alarm. This is a very useful feature, since an alarm in the basement may not be heard by sleeping individuals in an upstairs bedroom. However, getting this protection in an existing, older home was almost impossible until a few years ago when manufacturers started utilizing wireless technology to allow communication between multiple detection devices.
My wife and I recently decided to move our bedroom into the basement level of our home. It allowed our three children to all have a room of their own, but we were very concerned about what would happen if there was a fire and we did not hear an alarm go off on the upper level of our home. We were also concerned about the potential of carbon monoxide poisoning. It is the first time that we were not sleeping close to our children, as we were now down a level and on the complete opposite end of our home. We had a home security system installed, which also gave us some protection from fire, but we could not afford to have an adequate number of smoke and carbon monoxide sensors installed with it, as they were extremely expensive. Our security system is made by First Alert Pro, and when I explained my concerns about better protection, to the person installing the system, he recommended that we look into the OneLink combination smoke and CO alarms by First Alert. He told us that when one alarm goes off it sends a signal to every other OneLink detector in the house, causing all of the alarms to go off at the same time. He also told us that the alarms have a talking voice module, which actually tells you where the smoke or carbon monoxide is being detected. Research also shows that young children are more likely to wake up and take action when they hear a voice, rather than just hearing a beeping sound. I don't know much about that but I have read this information in several places on the Internet.
I could not find the OneLink combination smoke and CO alarms at any local retailers, but I was able to find them at several sites on the Internet. Needless to say, they are not cheap! However, after researching this model online, I was impressed by the features and I read a lot of glowing reviews for them. Since you can add as many detectors as you want, whenever you want, I decided to start out with three of them and add more as I could afford them. The included instruction manual is pretty straightforward but setting up and installing the first detector was a little tricky. It's not that complicated but timing is a key element in programming this alarm. You start out by installing 2 AA batteries (included in the package), which will cause the alarm to say "Welcome, First Alert Smoke and Carbon Monoxide Alarm. No location programmed. To select location, press and hold test button now." This is where the timing part comes in. As instructed, you press and hold the test button until the Alarm starts speaking again, at which time you release the button again. When you do this, the voice module will say "To save location, press and hold test button after desired location is heard." The voice will then begin listing off room names in a typical house. The choices are as follows: Basement, Living Room, Family Room, Office, Kitchen, Dining Room, Hallway, Child's Bedroom, Master Bedroom, Guest Bedroom, Utility Room. Once you hear the name of the room that you want to setup the detector for, you must quickly press and hold the button down. It will announce the room name you have chosen and will tell you that the location has been saved. If you mess up this step, you can remove the batteries, wait for a couple of minutes and reinstall the batteries again, to start the entire process over.
To add and link additional OneLink alarms, you must hold down the test button when you insert the batteries. Once you hear the unit chirp you release the button. At this point the green power LED should start to blink. You are then to hold down the test button on the first alarm you setup, until the second alarm chirps. You repeat these steps for each additional OneLink alarm you wish to integrate into your home. Once you have the main programming completed, mounting the devices is as easy as installing any other basic smoke detector, using the provided mounting screws.
My wife and I started by purchasing and installing three of the First Alert OneLink Battery Operated Combination Smoke and Carbon Monoxide Alarms (SCO501NC-3ST). As all First Alert OneLink devices can be linked with each other, we will likely add a few smoke-only detectors in the near future. We have installed one of the OneLink detectors in the kitchen, one in the hallway (right outside our children's bedrooms), and one just outside our bedroom in the basement. So far they have been working flawlessly. We test them every couple of weeks or so, and pushing the test button on one detector causes them all to go off, as they are supposed to. The real test was when my wife recently had a "cooking accident," which caused a fair amount of smoke in the kitchen. The alarm in the kitchen went off first, which triggered the other two OneLink alarms in the house. I was in my office downstairs when the basement alarm sounded; saying "Warning, Evacuate, Smoke in Kitchen, Evacuate!" Shortly after I silenced the kitchen alarm, the hallway alarm went off, which set off the other two alarms as well. This time the spoken warning stated that smoke was detected in hallway. The alarms simply added to my wife's frustration in trying to get the burning dinner situation under control, but I was delighted that the alarms were working as promised.
The First Alert OneLink Combination Smoke Alarm and Carbon Monoxide Detector allows you to build a safety network of wireless, interconnected alarms in your home. You can wirelessly connect up to 16 OneLink alarms in your home. When one alarm sounds they will all begin to sound. This device features a talking alarm, with an actual voice that speaks the type and location of the danger in your home. It is a 2-in-1 device, giving your home protection from both smoke and carbon monoxide. The smoke detector uses photo-electric technology, which helps prevent false alarms like those caused by cooking and shower steam. An EZ access battery drawer provides the ability to change the batteries without removing the alarm from the ceiling. The CO sensor is an electrochemical type, which is the most accurate technology available for detecting carbon monoxide. The OneLink produces a loud, 85db alarm, plus a talking alarm for added safety. The package includes the OneLink combination smoke and CO detector/alarm, a pair of AA batteries, mounting hardware and instruction manual. First Alert claims that this device has a 6-year lifecycle. The OneLink alarm will give a special chirping pattern, to let you know once the device has reached end of life. The device is covered by a 5-year limited warranty.
My wife and I are extremely happy with our purchase of the First Alert OneLink Combination Smoke and CO detectors. We no longer have to worry about an alarm going off upstairs, while we are asleep downstairs and therefore unaware of the danger to our children. We sleep much better at night knowing that our entire family is safe. I definitely plan to install more OneLink detectors throughout our home in the near future. Although the setup can be a little tricky, your first time, it gets easier as you program more of them. My only concern is the battery life, since they run on just two AA batteries. The instruction manual suggests that you test the alarms once every week, but to save battery power I test ours once every other week. The alarms do have a talking low battery alert, which is supposed to sound every 5 hours or so when the batteries are in need of replacement. We have had our OneLink detectors installed for about 3 months now and have had no problems with them. I cannot give the OneLink detectors 5 stars, due to their inflated cost, but I think they deserve 4 and ½ stars for their quality and advanced technology. I definitely would not want to be without them in my home and I highly recommend them to everyone.
