Hi gmanteaw26,

 

Thanks for reaching out. A few questions: what type of Nest Protects do you have? Are they battery or wired? What is the exact message or code you receive? Were you able to try resetting your Nest Protects? 

 

Best,

Jenelyn

I have wired  Nest Protect Gen 2. I am trying to replace 7 interconnected smoke detectors with Nest Protect. I started out with 4 Nest Protects and disconnected the 3 remaining smoked detectors. Not sure if all 7 need to be installed before they get the power.

Hey everyone,

 

@gmanteaw26, thanks for reaching out to the Community and for the follow-up information. I’m sorry to hear that you’re having issues with Nest Protect and for the delayed response here. I’d be happy to help you with this. Let’s check it out.

 

If you get a “Heads up! Power out“ message from your Protect smoke and CO alarm, follow these steps:

 

1. Check the breaker or fuse box.

 

When power goes out to only a part of your home, one or more switches on the breaker box may not be turned on, or a fuse could be blown.

 

If you have a fuse box, check for blown fuses and replace them. If you have a breaker box with switches, check that the switch controlling power to your Protect is switched on. Flip the switch off and on again. If your Protect’s green power light turns back on after you flip the switch, that was most likely the problem.


 

2. Check the wiring.

 

Wiring issues usually crop up during or right after installation, but wires can sometimes become disconnected later, especially if the connections weren’t securely terminated with a wire nut.

 

Note: If you had a professional install your Nest Protects, contact them to diagnose and fix wiring issues. A trained professional knows how to safely deal with high-voltage equipment and ensure proper connection for all wires. You can also contact a Nest Pro installer in your area.

 

Here are the steps to check your Nest Protect wiring. Refer to your Nest Protect User Guide for more wiring details.

 

1. Turn off the power.

 

Protect yourself against high voltage. Switch off the breaker switch or remove the fuse. Double check that any lights, appliances or other electronics connected to the same circuit are off.

WARNING: Failure to turn off the power may result in serious electrical shock, injury or death.

 

2. Remove your Nest Protect.

 

To remove your Nest Protect, gently twist it counterclockwise.

 

3. Check the power connector.

 

Make sure the connector is fully inserted into the back of Nest Protect. If it wasn't, turn the circuit breaker to switch back on. If the small green light still doesn't illuminate, turn the circuit switch off again, and try step 4.

 

4. Check the wiring.

 

Check that the power wire (usually black) and neutral wire (usually white) connections are connected to the right wires on Nest Protect's connector. Refer to your Nest Protect User’s Guide for more details.

 

There must be a solid contact between the power wires. Make sure that all wire connections are capped with a wire nut that has been twisted until secure.

 

5. Turn the power back on.

 

Flip the circuit breaker switch back on, and check if the Protect's green power light is on. The status in the Nest app may take a few minutes to change, so it's best to check the light.

 

If your Nest Protect still hasn't turned back on, contact a local professional installer.

 

Keep me posted.

 

I appreciate the help, Jenelyn.

 

Regards,

Lance
