Works With
A reliable, hardwired smoke and CO detector that suits homeowners with existing wiring and Google Home setups but falls short for those wanting advanced smart features or easy installation.
The First Alert Hardwired Smoke and Carbon Monoxide Detector offers a reliable combination of smoke and CO detection in one unit, which is convenient for homes looking to cover both hazards without installing separate devices. It integrates with Google Home, allowing for voice alerts and some smart home functionality, though it lacks advanced app controls like remote silencing or detailed event logs found in more expensive models. The hardwired design ensures constant power without worrying about battery replacement, but it does include a battery backup that typically lasts a few years. Installation requires some electrical knowledge and is best suited for users comfortable working with home wiring. The alarm is loud and meets safety standards, but it lacks features like voice alerts or interconnectivity with other smart detectors from different brands, limiting flexibility. Compared to battery-operated options, it offers more reliability in power but less portability. This detector is ideal for homeowners who want a dependable, wired solution integrated with Google Home and who don’t need extensive smart features. However, renters or those wanting easy DIY installation or more app control might find it less appealing. Also, the price is higher than some basic detectors, so budget-conscious buyers should consider if the hardwired aspect is necessary for their setup.

Connectivity

Compared to the Nest Protect, the First Alert offers simpler Google Home integration but lacks Nest's advanced app features like self-testing and split-spectrum sensors. The Kidde Smoke & Carbon Monoxide Detector is generally cheaper and easier to install (battery-powered), but it doesn’t offer smart home integration. The First Alert is a solid middle ground for those wanting hardwired reliability with some smart features, but if you want a more feature-rich app experience, Nest Protect is a better choice despite the higher price and battery dependency.
Installation rates around a 3 out of 5 in difficulty. It typically takes 30-45 minutes for someone with basic electrical knowledge. You’ll need a screwdriver, wire strippers, and possibly a voltage tester. The device must be connected to existing 120V wiring, so if your home isn't pre-wired for smoke detectors, professional installation is recommended. Common issues include ensuring correct wiring and securing the unit firmly to the ceiling or wall.
Users report reliable daily performance with fast alarm response times to smoke and CO detection. The hardwired power source means you rarely worry about dead batteries, though the backup battery needs replacement every few years. The app experience is basic—mostly notifications through Google Home rather than a dedicated app interface. Some users mention occasional false alarms triggered by cooking smoke or steam, which is common in many detectors.

Homeowners seeking reliable smoke and CO detection with smart features.
Consider compatibility with existing smart home devices before purchasing.
Buy this detector if your home is already wired for hardwired smoke alarms and you want Google Home compatibility. Pair it with additional First Alert units for better interconnectivity. Avoid if you prefer easy DIY installation or advanced app controls. Don’t overlook professional installation if you’re uncomfortable with electrical work to ensure safety and proper function.
