This item works very well just what I needed so that I get notified of an alarm at my house when I'm not home. This was an upgrade to the system I have in place without replacing every smoke head I have,

Easy Install

The product came with all the hardware needed for the install. Enrolling it into HomeKit was easy if you strictly follow the instructions. I ran into some trouble and had to reset and start over.

Great product

The directions were very clear, the installation was simple, the setup and configuration was straightforward. I specifically like the ability to know which alarm was the source of the detection and the remote monitoring when I'm out of the house.

Easy Installation

Purchased the One Link hardwired detector to compliment our Home Kit accessories. Installation was simple as we current have First Alert hardwired detectors - The quick connect harness from our previous detector fit this system. Home Kit setup took longer than installation, but I expected technology issues….Here's to hoping that the detector sits mounted to the ceiling and never needs to be active!!

installation was pretty easy, hard part was navigating my step ladder into and out of the house. You can launch the OneLink Home app from within AppleHomekit to see detectors status smoke and carbon monoxide and battery status, and you can initiate alarm test from your cellphone. I haven't had a fire yet or a CO alert when not home or even if I was home, but presume those notifications will be delivered to my iPhone. Now if they would only make a OneLink explosive gas detector for natural gas, LP leaks...

Easy setup

All the parts I needed to hard-wire this unit to my house were in the box. After install using the app to set up WiFi and alerts was just as simple. Setup was easy.

warranty replacement

This was a warranty replacement for a dead on arrival battery. Upon installation the original unit started complaining that the battery was low. A quick call to customer service got this unit. Out of eight units this was the only one with an immediate problem.

follow on purchase

This was a follow on purchase to a pair of Onelink smoke & CO alarms. The first pair have been working well for a month so I bought more. Setup was still a bit troubled, but resetting a couple of times got me through it again.

Straightforward setup

Despite some confusion, probably stemming from the VPN configuration on my iPhone, the setup of two hardwired alarms was straightforward.

Almost Perfect

I love that Onelink works with HomeKit, Apple's smart home platform. I've been able to set up many automations thus far. Setup was somewhat easy. It took several tries to get it to pair. I would also like the nightlight feature to include a motion sensor. So it turns on when you walk by and then turns off when you walk past it.

What features can I use if Wi-Fi goes out?
You will be able to use the alarm functions and bluetooth streaming from a device - Alexa functionality and receiving push notifications require a Wi-Fi connection.
How do I install a First Alert Hardwired Smoke & CO Alarm?
  • Switch off the circuit breaker for the area where you'll be installing the Smart Smoke + CO Alarm.
  • Install the new mounting bracket.
  • Use the included easy adapter to plug your alarm into your home's AC power.
  • Hold the alarm firmly against the mounting bracket.
  • Twist the alarm clockwise until it can't be turned further. You will hear a single loud chirp when mounting is successful. This means the backup battery has been activated.
  • Switch your circuit breaker back on.
  • Check the alarm. It will pulse blue when it's activated and ready to pair with your mobile device.
Can I turn off the night light feature?
The LED lights on the Onelink alarm not only provide a nice glow to light up your route, but they also indicate that the alarm is receiving AC power. You can adjust the brightness level of the nightlight through the Onelink app. When you disable the nighlight two LEDs will glow green on the Onelink alarm letting you know that you have AC power. If the LED is turned off, it indicates your alarm is running off of battery backup.
Why can't I change my nightlight color to red in the Onelink Home App?
The color red has been reserved for smoke and carbon monoxide emergencies as well as Alexa privacy mode.
Will the Onelink Safe & Sound work with my other smart detectors?
The Onelink Safe & Sound will interconnect with most hardwired smoke and CO alarms. This includes all BRK and First Alert alarms and most Kidde, Fyrnetics, Lifesaver and Firex alarms.
What is the distance you need to be within to interact with the Onelink Safe & Sound?
You need to be within 15 feet.
Does the Onelink Safe & Sound require rewiring?
Included with the Onelink Safe & Sound are easy adaptor plugs, so you do not have to rewire to install your alarm.
Does this device support Alexa?
Alexa voice services are not supported, so you can't talk to Alexa with this unit. However, if you have an Echo or similar Alexa-enabled device, you can use Onelink Alexa skills to check in on your detector. The nightlight on the hardwired alarm can also be controlled with Alexa.
Does this product require professional installation?
The Onelink Safe & Sound is meant to be a DIY installation. To install, simply remove your current alarm and bracket and install the Onelink Safe & Sound. The app will guide you through the process. Included with the Onelink Safe & Sound are easy adaptor plugs, so you do not have to rewire to install your alarm.
I just installed my Smart Smoke & CO Alarm. Why does it keep beeping and chirping?
Sometimes, alarms may beep or "chirp" to let you know that something isn't right. A chirp is quieter and more intermittent than a regular alarm. Chirping is typically caused by improper mounting, a low battery, or alarm end-of-life.
