How to Install First Alert 1039102 Onelink Safe & Sound Hardwired Smoke & CO Alarms:

In this guide, we'll be showing you how to install First Alert Hardwired Smoke and Carbon Monoxide Alarms. Here are a few items you'll need before starting the installation process: Needle-nose pliers or utility knife, screwdriver, wire stripper, wire nuts and a ladder.

Hardwired Smoke or Carbon Monoxide Alarm Requirements:

  • 120V household electrical circuit (unswitched 120VAC)
  • Standard wiring junction box to a 4 in. (10 cm) size, on either the ceiling or wall
  • Selecting an appropriate location to install your smoke and carbon monoxide alarms (see below guidelines for additional information):
    first alert smoke alarm install guide
    • When installing an alarm on the wall, the top edge of an alarm should be placed between 4 in. (100 mm) and 12 in. (300 mm) from the wall/ceiling line.
    • When installing an alarm on the ceiling, place the alarm as close to the center as possible.
    • In either case, install the alarm at least 4 in. (100 mm) from where the wall and ceiling meet.

Connecting First Alert Hardwired Alarms to 120V Wiring

To begin, turn off power at the junction box and connect your alarm to the building's electrical wiring.

  1. Locate the junction box and turn off power
  2. Remove the power connector from the new alarm's packaging
  3. Using wire nuts, attach the hot (black), neutral (white), and interconnect (orange) wires

Black wire
(hot)
Attach to black wire on power connector
White wire
(neutral)
Attach to white wire on power connector
Orange wire
(interconnect)

Standalone (single-station) alarm: This wire is not needed; tuck the orange wire into the junction box.

Interconnected alarms:

  • Strip 1/2 in. from the orange wire on the connector
  • Use a wire nut to attach it to the orange wire in the junction box (see image below).

Mounting First Alert Hardwired Alarms

  1. Secure the mounting bracket to the ceiling or wall using screws (included in the package)
  2. Insert the power connector into the plug on the back of your alarm
  3. Tuck any hanging wires into the junction box
  4. Position the base of the alarm onto the bracket and turn it clockwise until it's secured
  5. Remove the pull-tab to activate the backup battery

Installing Additional and/or Interconnecting First Alert Hardwired Alarms

If you are installing more smoke or carbon monoxide alarms, you'll want to repeat the process throughout the building. Interconnected smoke and co alarms must meet all requirements:

  • The same fuse or circuit breaker must power all interconnected alarms.

  • Up to 18 compatible detectors can interconnect, with a limit of 12 smoke alarms.

  • The total length of wire interconnecting the alarms should be less than 1,000 ft. (300 meters). This type of wire is commonly available at hardware and electrical supply stores.

  • All wiring must conform to all local electrical codes and NFPA 70 (NEC). Refer to NFPA 72, NFPA 101, and your local building code for more information.

  • Interconnect wiring diagram:

If you have any doubts or reservations about these interconnect requirements, please contact an experienced electrician to install your wiring and hardwired alarms.


Restoring Power and Testing Hardwired Alarms

Once you've installed your hardwired alarms, you'll want to restore power to the junction box. Under regular operation, the power indicator light on the alarm will shine/blink to indicate that it is receiving AC power.

Here's how you can test standalone or interconnected alarms:

  • Standalone Alarms: Press and hold the Test/Silence button until the unit triggers an alarm.

  • Interconnected Alarms: Press and hold the Test/Silence button until the first unit triggers an alarm. All interconnected detectors should sound off. Repeat this process to test each alarm in the interconnected series.

Can I play music to other Alexa devices or my Everywhere group with Safe & Sound?
Not at this time. Alexa and Safe & Sounds keep getting smarter over time, so you can look forward to more audio capabilities in the future.
Does the Onelink Safe & Sound require rewiring or professional installation?
The Onelink Safe & Sound is meant for DIY installation. Just remove your current alarm and bracket, and install Safe & Sound. Easy adapter plugs are included, so you don't have to rewire to install the alarm.
Once the Safe & Sound unit is wired into my ceiling, what are the next steps?
Once the alarm is installed, the unit will walk you through setup and Alexa integration with Onelink Home app. If you have more than one Safe & Sound, set each one up though the app as you install the units, before moving on to the next one.
How does the Safe & Sound nightlight feature work?
When set on autobrightness, the LED lights glow to light your route in the dark, and get brighter in the day, to ensure visibility in an emergency. You can turn off autobrightness, or adjust brightness and usage through the Onelink app.
Do the LED lights on Safe & Sound also indicate power?
The LED lights also indicate AC power is being received. When you disable the nighlight, 2 LEDs will glow green on the Onelink alarm, letting you know that you have AC power. If the LED is off, your alarm is running with battery backup.

Ionization alarms are generally more sensitive to fast flaming fires and photoelectric alarms are generally more sensitive to smoldering fires.

Better than expected!

I bought this to replace my expiring nest protect smoke alarms because of the Airplay, homekit support and speaker. The iOS app could be improved as it difficult to navigate and the auto brightness night light feature does not change with changes in room lighting. Nothing wrong that will likely be addressed in future software updates.

Better than a NEST

Setup was smooth and so far it works well. Like the speaker, and it has a nice sound. Waiting on Airplay 2 support. And wish there was some way to completely disable Alexa support.

4-stars for now... AirPlay 2 for the 5-star WIN!

The Safe&Sound was incredibly easy to install, looks beautiful, and sounds great when streaming music. I don't have Alexa, so I can't speak to that compatibility, BUT, I can say it integrates nicely with HomeKit, and now the only feature I am waiting for which is the biggest reason I selected this alarm, is AIRPLAY 2!! For that weird hallway that my other speakers don't reach, the Safe&Sound will be a wonderful addition to my full-home sound system. I'm anxiously awaiting that upgrade, and will have ZERO complaints once that's fully functional! Highly recommend.

Good Product

Pushing only button on the detector 3 times to initiate pairing to mobile device would not work - had to disconnect power. Once paired the rest of the setup was easy. Sound quality is good but wish it was a little louder.
