Nest Protect – Smoke Alarm – Smoke Detector and Carbon Monoxide Detector review

Design

The Nest Protect comes in both wired and battery-powered versions. If you have more than one in your home, and one goes off, the others will too, alerting you to the location of the fire.. 5.3 x 1.5 x 5.3 inches, ‎1 pounds. An LED ring on the bottom of the alarm also changes color, giving you a visual cue.

Sensors

The Nest Protect uses a split-spectrum sensor that Nest says is good at detecting both slow-smoldering fires as well as fast-burning ones. It’s a photoelectric sensor, which is generally better at sensing smoldering fires (ionization sensors are faster at quick-burning fires, but are more prone to nuisance alarms), but Nest’s sensor has a second wavelength that’s better for picking up flaming fires. In addition, the Nest Protect has sensors for carbon monoxide, heat, humidity and occupancy.

Phone alerts

Yes, a siren is very helpful in alerting you to a fire, but doesn’t provide any information other than that. Nest Protect is different in that it also provides spoken alerts, which not only tell you the nature of the emergency (smoke or carbon monoxide), but also the room in which it’s occurring.

Apps feature in Nest Protect – Smoke Alarm – Smoke Detector and Carbon Monoxide Detector

On top of keeping your family safe, it comes with a few aggravation-saving features. Its app will tell you when the battery is low so you don’t need to listen to a constant beeping noise until you change the battery. You can also turn off false alarms with the app. No more using a broom handle to tap the button.

Nest Protect can connect with other Nest Protect alarms in your home to create a network of safety. This means voice alerts could tell you where smoke or fire was detected. This can keep you safe as you exit your home because you’ll know which rooms to avoid.

Through the Nest app, you can monitor the status of the detector, as well as any other Nest products you have, such as the Nest Cam and the Nest Learning Thermostat. The app gives detailed information on when the Nest Protect last checked itself, and if there are any issues. From here, you can also silence the alarm if it goes off accidentally while you’re cooking a steak, for example.

Installation

To install the Nest Protect, you first screw a base plate into the ceiling, and then attach the main body of the smoke detector onto the base plate. Then, you connect to it using the Nest app on your smartphone (Android and iOS), specifying, among other things, in which room the Nest Protect is located. It’s a fairly simple process that took me about 5-10 minutes.

Smart Home Integration

You can link the Nest Protect to other smart-home systems, such as Google Home (and the Mini and Max), TP-Link smart plugs and Philips Hue lights.

However, this only applies if you still have the Protect registered under a Nest user account, and not a Google Assistant account. Last year, Google started the process of merging Nest with Google Home/Assistant, but almost all of the functionality available within Nest has not been enabled within Google.

Performance

We tested the Nest Protect (as with all smoke detectors) by spraying an aerosol smoke-detector-tester spray from 5, 10 and 15 feet away, and timing how long it took each alarm to go off. At the 5- and 10-foot mark, the Nest Protect sounded after 18 seconds. At 15 feet, the alarm activated after 28 seconds. Moreover, it was the only device to pass all of our tests.

Preeminent Protection for Your Loved Ones

Nest Protect Smart Smoke/Carbon Monoxide Alarm provides the ultimate protection & peace of mind. The intelligent alerts discriminate between steam and smoke. A clear “Heads Up!” pre-alert gently cautions you in situations when close proximity to steam or a little smoke in the kitchen, for example, is about to trigger an alert. You can silence a false alarm using your phone. Multiple units share alerts to all rooms & to your NEST App on your phone, tablet & computer – so you are protected throughout your home! The “Promise” is a ring of green light that illuminates nightly to let you know everything is good.

Walk under NEST at night & the ring glows white, forming a pathlight. During Heads Up, it glows yellow. During an emergency, it glows red. NEST Protect self-tests, alerting you first by the phone app that it will sound. Everything is tested: sensors / voice / siren. Tests are dated & are sent to your app. A monthly summary even shows the exact date & time of each test. This is the premiere smoke detector, able to detect CO2 (even produces a completely different sound, for instant identification).

NEST Protect senses both fast and slow burning fires. NO CHIRPS!! This advanced Smoke Alarm eliminates all of the hassles of pesky chirps from low batteries, with super long lasting Lithium Batteries included that last years. Battery alerts are through your App & by voice on the Alarm. To set-up, simply scan the QR Code on the back of the NEST & follow the voice instructions. Easiest set-up ever! NEST Protect earns my highest recommendation – no other Smoke / CO2 Alarm even comes close!

Alternate of Nest Protect – Smoke Alarm – Smoke Detector and Carbon Monoxide Detector

First Alert SA320CN: Best basic

The First Alert SA320CN is fairly basic compared to our top pick. It’s reliable, though, and that’s the most important thing when it comes to fire detection. Plus, First Alert has been around since 1958 and is highly trusted.

The 85-decibel siren could be louder, but we think it should do just fine if you place multiple alarms throughout your home. It can detect both fire and smoldering using its dual sensors, and it has a testing button that can also be used to mute the alarm.

It’s not the flashiest, but we think it’s a great pick if you need a budget-friendly, no-fuss smoke detector
