Kidde P4010ACSCO-WFCA Smart Wi-Fi Smoke & Carbon Monoxide Alarm – Hardwired Safety with Wire-Free Convenience

Protect your family and your finished home with the smartest dual-detection system on the market.

As a busy homeowner, you shouldn't have to choose between professional-grade safety and an expensive, invasive installation.

The Kidde P4010ACSCO-WFCA combines hardwired reliability with Wi-Fi intelligence, giving you real-time alerts on your phone whether you’re at the office, in the backyard, or away for the weekend.

It’s one of the best "set it and forget it" safety essential for the modern detached home.

Smart Home Protection: Safety You Can See From Your Phone

The Kidde P4010ACSCO-WFCA integrates seamlessly with the Kidde HomeSafe™ app, transforming a standard alarm into a proactive safety hub.

If smoke or carbon monoxide is detected, you don't just hear it—you see exactly what's happening via mobile notifications.

• Real-Time Mobile Alerts: Receive instant updates if the alarm sounds or if the unit is nearing its end of life, perfect for parents who are frequently on the go.
• Smart Hush® Control: Tired of smoke from a seared steak triggering the alarm? Silence nuisance alerts directly from your smartphone without needing a ladder.
• Whole-Home Connectivity: When one alarm in your house sounds, they all sound. Your phone tells you exactly which room triggered the event, saving precious seconds in an emergency.

Upgrade Your Whole Home Without Opening Your Walls

Most hardwired alarms require a physical "interconnect" wire to talk to each other—a nightmare for DIYers in finished homes.

The P4010ACSCO-WFCA changes the game with Wire-Free Interconnect technology.

By using a proprietary radio signal, these units link together wirelessly. You get the 120V hardwired power required by modern building codes, but you skip the "fish-tape" struggle of running communication wires through your ceilings. It is the highest level of protection available without the $500 contractor bill.

Product Overview

The Kidde P4010ACSCO-WFCA is a premium, hardwired combination alarm specializing in both fire and carbon monoxide detection.

Designed for "Worry-Free" operation, it features a 10-year sealed lithium battery backup.

This means you will never have to listen to a low-battery chirp at 3 AM or climb a ladder to swap out 9V batteries for the entire decade-long lifespan of the device.

Its Bilingual Voice Warning system removes the guesswork during a crisis. Instead of a frantic beep, a clear voice announces "FIRE!" or "WARNING! CARBON MONOXIDE!", ensuring your kids and guests know exactly how to react.

With a built-in Ambient Light Sensor, the unit even knows to dim its status LED at night, ensuring your family sleeps undisturbed.
