Kidde P4010ACSCO-WFCA Smart Wi-Fi Smoke & Carbon Monoxide Alarm – Hardwired Safety with Wire-Free Convenience
The Kidde P4010ACSCO-WFCA Smoke + Carbon Monoxide Alarm is a hardwired, Wi‑Fi enabled 2‑in‑1 safety device designed for residential use. It combines smoke and CO detection with app-based monitoring, interconnect capability, and a built-in 10-year sealed lithium battery backup.
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.
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.

What does the Kidde P4010ACSCO-WFCA detect?
It detects both smoke and carbon monoxide using separate photoelectric and electrochemical sensors within a single unit.
Does this alarm work during a power outage?
Yes. It is hardwired to AC power and includes a sealed 10‑year lithium backup battery to maintain operation during outages.
Can this alarm connect with other alarms in the home?
Yes. It can interconnect with up to 24 compatible Kidde hardwired alarms so all units sound when one is triggered.
How do I receive alerts from the alarm?
When connected to Wi‑Fi, the device sends notifications through the Kidde app for alarms, status updates, and maintenance alerts.
Does Wi‑Fi functionality always work?
No. Wi‑Fi features only function when the alarm is connected to AC power and a stable home Wi‑Fi network.
Does this replace my old hardwired alarm?
Yes. If your home already has 120V wiring for smoke detectors, this unit will fit your existing junction box. Even if your old alarms weren't "interconnected," these new units will talk to each other wirelessly the moment you power them up.
Do I need a special hub for the Wi-Fi?
No. This unit connects directly to your home's 2.4GHz Wi-Fi network. No extra hubs, no monthly fees, and no complicated bridging required.
