Tools and Hardware Reviews of First Alert SCO501CN-3ST (Series SCO500) ONELINK Battery Operated Combination Smoke and Carbon Monoxide Alarm with Voice LocationCustomer Review: $60 Product is Worthless After Only 5 Years
Bought 7 of these for my household....quite an investment in technology. When I recieve them, I notice on the packaging that there is an end of life cycle alarm that sounds after 5 years due to code rules on the CO alarm portion.

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 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.
