Hardwired with a 10-year lithium battery backup, it ensures continuous protection and integrates seamlessly with Alexa, Google Home, and mobile devices. Featuring an 85-decibel alarm, LED status indicators, and easy app-based installation, it’s engineered for smart, reliable home safety. ## Description The Kidde Smart Smoke Detector, WiFi, Alexa Compatible Device, Hardwired with Battery Backup, Voice & App Alerts, model P4010ACS-WF, uses photoelectric sensor technology to detect visible fire particles, associated with smoldering fires, and alerts you by sounding an 85-decibel alarm with voice alert announcing "Fire! Fire!". The Kidde smart hardwired smoke alarm connects to your home's wiring using standard 120V AC power voltage and provides battery backup in the event of a power failure. The lithium battery backup lasts the 10-year life of the alarm, so you'll have the benefit of never having to replace a battery. Update-to-date, real-time notifications are provided through the Kidde app, so your family & friends - even the pet sitter - can monitor your home's air quality & received alerts to smoke presence, high humidity levels that can lead to mold, unexpected high or low temperatures, or Total Volatile Organic Compounds (TVOCs). Setup is easy: simply download the Kidde app and scan the QR code at the back of the smoke alarm. You can also use voice commands to check the connection & status of carbon monoxide or air quality by pairing it with your desertcart Alexa, Google Home, and select iPhone & Android smart devices. The LED ring-light indicator alerts you to the unit's operational status: red = a smoke or fire hazard, amber = operating error, and green = normal operation. The Test-Hush button silences temporary nuisance alarms, tests if the unit is operating properly, and silences a low battery or end-of-life chirp (up to 24 hours at a time for a maximum of 7 days). Install a smoke detector on each level of your home and inside and outside each bedroom. The Kidde smoke detector is capable of hardwired interconnection to other select Kidde alarms for whole-home activation – when one alarm sounds, they all do**. UL Certified with a 10-year limited warranty (not a battery performance claim). ## Features - Voice Alarm announces the hazard type when detected: “Fire!” = smoke or fire or "Replace Alarm" when the unit has come to its end of life span - Easy Installation: download the Kidde app & scan the QR code on the back of the smoke alarm - Compatible with desertcart Alexa, Google Home, iPhone, & Android smart devices - 85-decibel alarm & LED warning indicators alert you to various status: green = normal operation, amber = operating error, and red = smoke, fire or carbon monoxide event - WiFi enabled technology allows notifications to be sent to your smartphone (as well as friends & family) in the event of a smoke hazard in your home - Photoelectric sensor technology detects visible fire particles associated with smoldering fires - Test-Hush Button easily tests the working operation of the smoke alarm & silences false alarms; the Kidde app can also be used to test the smoke alarm - UL Listed with a 10-Year limited warranty on the alarm only (not a battery performance claim).

I refuse to buy google products. This is the first one I have found that works. Setup was easy, I am sort of handy with electrial though. I replaced an 8 year old hard wired First Alert brand smoke detector. Undid the wire connectors and found I already had a neutral wire there. I am not sure that is normal or I just got lucky. I hooked up the new harness and walked through the instructions to download their app and add the smoke detector.So far this is just what I wanted and the price was good too. Only thing better would be if Kidde had built Home Assistant integration. But it looks like the Home Assistant community is working on that.I had previously bought a OneLink smart smoke detector. That is completely useless as a smart device. It only integrates with Apple HomeKit, which itself is a PITA to use. The onlink app is terrible. If you are comparing these 2 products and deciding, The Kidde device is far and away better.A couple days ago this smoke detector went off. I got an alert on my phone. Exactly what I wanted! It was a false alarm, someone was cooking in the kitchen and making more smoke than normal, but I was impressed. I just bought one of their water detectors to sit by my water heater. ### ⭐ Read all 1 Star Reviews - False Alarms make these a danger *by on Reviewed in the United States 19 May 2024* Installed 3 units in my home in September 2023. We had a few isolated alarms in January. I assumed the device was working correctly and that it had detected some cooking odors. Then in April we got two false alarms at night. It scared the crap out of my family. There was no smoke or fire.I followed the instructions and used a computer duster to blow into the sides if the device. By May the false alarms started occurring more frequently. I removed the device and cleaned it again.Today is May 19th. There has been 5 false alarms in the past 4 days. Three in the last 24hrs. 12:21pm Yesterday, 4:24am this morning and now again at 7:20am. This time the alarm will not shut off. Stating “too much smoke”. There is NONE. I had to remove it and put it in my garage because I could not get it to stop.Kidde support will state the device needs to the sensor blown off about every 6 months and that false alarms can occur due to dust contamination or insects. I’ve dusted my unit many times to no avail.Sadly Kidde support is lackluster. They will also state that the false alarms are likely due to being too close to an HVAC, vent, register, duct or flue. Mine is nowhere near any of those things. They will also state that all smoke detectors are prone to dust contamination and require regular dusting.I also have 3 Nest Protect devices in the same house. One is about 8 feet away from the unit which creates the most false alarms. None if the nest units have ever once triggered a false alarm, nor have I ever dusted them. They have been installed since 2017.I used to think Kidde made great products, but this is not one of them. The repeated false alarms create a sense of frustration and apathy in my household. Everyone will now assume that any alarm is a false alarm. This is extremely dangerous because it could result in delayed action or an inappropriate response to a real smoke or fire emergency.Based on a number of online discussions, Kiddie will only support these failed units if you ship them back to their support center at your own expense. They will not send replacements or offer any refunds.*Do not Buy* ### ⭐⭐⭐⭐⭐ Impossible to set up using an android device on a hybrid network. *by on Reviewed in the United States 14 May 2024* When installing this detector in a system that has a hybrid 5 ghz and 2.4 ghz network using a single SSID (that's not separated, google nest mesh network in my case), it's virtually impossible to set it up using an android device. Incredibly frustrating. Setting it up via iOS/iPad OS was the solution as I was able to get it to pair to the network using my backup device. Works great once you get it connected, but I've had this issue with other 2.4ghz only devices in the past so I knew to try the iPad. ## Frequently Bought Together - Kidde Smart Smoke Detector, WiFi, Alexa Compatible Device, Hardwired w/Battery Backup, Voice & App Alerts - Kidde Smart Smoke & Carbon Monoxide Detector, WiFi, Alexa Compatible Device, Hardwired w/Battery Backup, Voice & App Alerts - Kidde Smart Smoke & Carbon Monoxide Detector & Indoor Air Quality Monitor, WiFi, Alexa Compatible Device, Hardwired w/Battery Backup, Voice & App Alerts --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tw/products/740841246-kidde-smart-smoke-detector-wifi-alexa-compatible-device-hardwired-w](https://www.desertcart.tw/products/740841246-kidde-smart-smoke-detector-wifi-alexa-compatible-device-hardwired-w) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-08-19*
