Nest Protect (Wired 120V ~ 60Hz) Smoke Monoxide Alarm Manual

Meet your Nest Protect

Nest Protect is designed to detect smoke and carbon monoxide in a residential environment.
It has multiple sensors to help it understand what's happening in your home, including a Split-Spectrum Sensor to detect a wide range of slow-smoldering and fast-flaming fires.
This guide covers the installation of Nest Protect (Wired) - Model number 06C.

Requirements

You need Wi-Fi, an iOS or Android phone or tablet, and a free account in order to use some Nest Protect features: spoken room names, wireless mobile notifications, and software updates. During setup, Wi-Fi and a free account are required for wireless interconnect and room naming. After all the Nest Protects in your home are connected, they can communicate with each other without Wi-Fi.

Get the Nest app

Set up Nest Protect

The Nest app will guide you through each step: scanning the Nest Protect QR code, connecting it to the internet, and connecting it to other Nest Protects in your home. Go to g.co/nest/installprotect to watch the video.

Tip: Lay everything out on a table for easy setup.

Have more Nest Protects?

The Nest app will ask if you have more Nest Protects to set up. If you do, it'll take you through a faster setup. Be sure to keep all your Nest Protects together until they're all set up and ready to be installed.

Tip: Your Nest Protect came packed in a plastic cover. Keep the cover on so your Nest Protect stays clean until you install it.

Test before you install

Once you're done setting up all of your Nest Protects, make sure they've been added to your account. Push the button on one Nest Protect and follow the instructions. All of your Nest Protects should speak up. Now you can install them on the ceiling or wall.

Tip: To double check Nest Protect's room name, press the button once. You'll hear the location you assigned it during setup. It'll say something like,
"Ready in the bedroom."

Turn off power

Protect yourself and avoid blowing a fuse. Switch off the correct circuit breaker for the room where you are installing Nest Protect or remove the fuse from the fuse box.

ELECTRICAL SHOCK HAZARD
Failure to turn off the power may result in serious electrical shock, injury and death.

Remove your old smoke alarm

To prevent electrical shock, make sure the green Unscrew the backplate from the electrical box. Save power light is off on the alarm. You may have to twist the screws to install the Nest Protect backplate later. the alarm to release it. Carefully remove it to keep from damaging your ceiling or wall.

Tip: Your old smoke alarm might make a loud noise when you disconnect it.

Remove the old backplate

Unscrew the backplate from the electrical box. Save the screws to install the Nest Protect backplate later.

Location in your home

The National Fire Protection Association (NFPA) recommends installing a smoke alarm in the following areas:

• On every floor, including finished attics and basem*nts.
• Inside and outside every sleeping area.
• At the top of the first- to second-floor stairway and on the basem*nt ceiling near the entry of the stairs.
• In homes with more than 1,000 square feet (93 m² ) on one level, additional alarms may be required.

Nest Protect should be installed at least 10 feet (3 m) away from cooktops or cooking appliances. Nest Protect should NOT be installed in unfinished attics or garages.

Remove the old connector

Unscrew the wire connectors to detach the 120V connector from your old smoke alarm.

The exposed wire should be straight.

Attach the Nest connector

Hold the white wire ends together, cap them with a wire connector and twist clockwise until it's secure. Do the same with the black wires. There's no need for the red/orange/yellow wire. Simply cap it with a wire connector and twist until secure.

Placement on the ceiling or wall

Installing on the ceiling is recommended. Mark where the screws will go using the base as a guide. If you're installing on the wall, make sure it's within 12 inches of the ceiling.

Placement on a sloped ceiling

If you have a sloped, peaked or cathedral ceiling, Nest Protect should be 4 inches to 3 feet (10 cm – 1 m) from the highest point.

Install the new backplate

Screw the Nest Protect backplate to the electrical box, reusing the old screws. You can also screw the backplate directly into the wall or ceiling with the Nest Protect screws. Make sure the screws are all the way in and snug against the backplate.

Tip: All smoke alarms prefer to live in a dust free area, so remove any dust before you install Nest Protect.

Connect power

Plug the 120V connector into the back of your Nest Protect.

Install your Nest Protect

First, tuck any excess wiring into the electrical box.
Line up the three tabs on the back of your Nest Protect with the notches on the backplate. Hold Nest Protect against the backplate and turn it clockwise. Continue turning until it's square with the wall or ceiling. Install the rest of your Nest Protects if you have more.

Tip: If you ever need to remove it (for cleaning or battery replacement), turn off power to your Nest Protect at the breaker box or remove the fuse first. Then turn counterclockwise until it disconnects from the backplate.

Switch power back on or replace the fuse

Breaker box

Press to test

Press the button on one Nest Protect. It will tell you what to do next. Every Nest Protect in the house should speak up, confirming that they're connected to each other.

Heads-Up and Emergency Alarms

Alerts

Silencing

Heads-Up alerts and some Emergency Alarms can be hushed by using the Nest app or pressing the button. In some cases, the smoke level may be too high for the Emergency Alarm to be hushed. Only silence an alarm once you have checked conditions at the Nest Protect that first sounded the alarm. Do not silence Nest Protect by disconnecting it from line voltage and removing the batteries. This will disable the alarm so it cannot sense smoke or carbon monoxide, leaving you at risk.

Because there are many different types of fires, you may experience an Emergency Alarm without having first experienced a Heads-Up alert. This means that critical levels of smoke or CO occurred extremely quickly and Nest Protect has to sound the Emergency Alarm.

Have more than one Nest Protect?

After all the Nest Protects in your home are connected to each other, if there's a Heads-Up or an Emergency Alarm in one room, they'll all tell you what the danger is and which room it's in.

If multiple Nest Protects are interconnected, a Heads-Up alert or Emergency Alarm can be silenced only at the Nest Protect that originally sounded the alert. You'll need to go to that room to silence all the Nest Protects in your home. Always check the conditions near the Nest Protect that first detected the smoke or carbon monoxide before silencing it.

Daily Use and Emergency Preparation

Daily Use

Power

Nest Protect (Wired 120V) has a small green light located at the top of the button. It will be on as long as Nest Protect is getting AC power from the electrical wires.
If there's a wiring problem or power outage, the green light will turn off and Nest Protect will switch to backup batteries. You'll also see a yellow (instead of green) Nightly Promise light when you turn off the lights for the night.

Nightly Promise

Nest Protect continuously tests itself, so you don't have to wonder if it's working. Nightly Promise reports on every Nest Protect in your home.
When you turn out the lights for the night, Nest Protect will glow green for a moment – that means everything is working. If it glows yellow, one of the Nest Protects in your home needs your attention. For instance, the batteries are low, Wi-Fi is down, or there's an issue with the sensors. Just push the button or use the Nest app to see what's wrong.

Pathlight

Usually Nest Protect has its light turned off, but it can light your way as you walk underneath it in the dark. You can enable or disable Pathlight and set its brightness with the Nest app.

Emergency Preparation

Testing

Perform a manual test of your wired Nest Protect at least weekly. During a test, all interconnected Nest Protects in your home check their sensors, power, Wi-Fi connection, light ring, emergency horn, speaker and microphone.
When you run a test, Nest Protect will give you a countdown before sounding the alarm so you have time to move away from the loud noise.

Test procedure:

1. Start a test by pressing the button twice.
2. Nest Protect will say: "This is only a test. The alarm will sound."
3. Ensure that the alarm sounds and the light illuminates on each Nest Protect.
4. Once the Nest Protect has made sure it's working, it'll tell you everything's okay. If you have interconnected Nest Protects, all of them should speak.

Sound Check

Nest Protect can automatically perform a monthly test to confirm that its speaker and horn are working properly. You can choose to enable this option during initial setup with the app, but you can change it at any time. For more information, visit g.co/nest/soundcheck

General Maintenance

Cleaning your Nest Protect

Nest Protect has been designed to be as maintenance free as possible, but you should keep it clean. As with any smoke alarm, dust buildup on the outside or inside of Nest Protect can stop it from working properly.

To clean Nest Protect:

1. Remove it from the wall or the ceiling (turn counterclockwise until it comes off the backplate).
2. Wipe the outside with a clean, slightly damp cloth. Don't use any soaps or solvents.
3. Place Nest Protect on a soft, dry cloth with the button facing down. Open the battery compartment door and remove the batteries. Remove the screws and lift off the back. Be careful to not lose the screws.
4. Gently vacuum the inside. Make sure to clean all the way around the mesh sides of the smoke chamber (the large metal circle).

   Note: Never use detergents or solvents (like glass cleaner) on your Nest Protect and do not spray air fresheners, hair spray or other aerosols near it. Do not get water inside the alarm or paint over it.

Replacing the backup batteries

In case of a power outage, Nest Protect will use three AA Energizer^® Ultimate Lithium batteries (L91) for backup. These batteries can be purchased at your local retailer.

1. Turn off power to Nest Protect at the breaker box (see p.9)
2. Twist Nest Protect counterclockwise until it disconnects from the backplate.
3. Detach the power connector from the back of Nest Protect and open the battery door.
4. Replace the batteries. Align the + positive and - negative ends with the markings in the battery compartment.
5. Close the battery compartment. Do not force the door closed.
6. Reattach the power connector.
7. Push Nest Protect onto the backplate and turn it clockwise until you feel it grip.
8. Turn power to Nest Protect back on at the breaker box.
9. Press the button twice.
