Detection

During our evaluation process, we put the First Alert Onelink through a battery of tests. We hardwired it into our testing apparatus, then sprayed faux smoke from an aerosol can directly at it. When we sprayed the smoke from 5 feet away, it took 23 seconds for the alarm to go off and at 10 feet, it took 31 seconds – both times were slightly longer than average.

It failed to detect the smoke at all when we sprayed it from 15 feet away, even after we expended the full can. However, it’s important to note that only one of the alarms we reviewed detected smoke from that distance, which reinforces the fact that you need to install smoke detectors throughout your home.

Design

We found that the First Alert Onelink is very easy to set up – it only took a few minutes to mount it and connect it to a power supply. If you’re installing more than one of these smoke detectors, you can connect them all over Wi-Fi or Bluetooth. This allows them to work together and provides more comprehensive coverage.

The First Alert Onelink is fully compatible with Apple Homekit – a platform designed by Apple to network devices such as thermostats, motion sensors, smart locks, smart plugs and lightbulbs. You can use the Apple Home app to control all these items and your smoke detectors, so if you want a complete home automation system, this is a good way to go.

For the First Alert Onelink to work properly, you must hardwire it into your home’s electrical grid, which serves as an uninterrupted power source. The device also comes with a 10-year sealed battery that functions as a backup if there’s a power outage.

Alerts

Like all smoke detectors on the market today, when the First Alert Onelink detects danger in your home, a loud tone alarm sounds. What makes this device stand out is its voice alarm – a voice plays through the device’s speaker and tells you exactly what it detected and where it’s located. If you have multiple detectors networked together, this voice alarm sounds on all of them so everyone in the house hears about the problem.

As mentioned above, you can connect this device to the Apple Home app. However, if you don’t use that platform, First Alert offers its own mobile app you can use to control, test and monitor your First Alert Onelink. It’s not as comprehensive as Apple Home, but it connects you to your smoke alarm as well as First Alert’s home environment monitor. Beyond detecting smoke and carbon monoxide, this allows you to track and change your home’s temperature and humidity.

The Onelink app notifies you immediately if the device detects an emergency in your home. This is especially convenient when you’re away and need to contact local emergency services to deal with the crises.

Warranty & Support

This smoke and carbon monoxide detector lasts about 10 years, and the manufacturer’s warranty covers it for its entire expected life. Even if it stops working in year nine, the company can replace it for you. This is a great indication of First Alert’s confidence in its products.

Even though the First Alert Onelink is easy to install, set up and use, you may need to contact customer or technical support. You can reach the company by phone and email, which is sufficient for most users. However, other manufacturers we reviewed also offer assistance over social media and live chat and have FAQs sections on their websites.

Summary

If you’re in the market for a first-rate smoke alarm, the First Alert Onelink is worth your consideration. It’s easy to use and detects smoke and carbon monoxide better than most of its competition. It also works well with First Alert’s mobile app and integrates seamlessly with Apple Homekit. In addition, it has a long lifespan with a warranty period to match.
