The Kidde Smart Smoke and Carbon Monoxide Detector is a hardwired, Wi-Fi-enabled alarm that integrates directly with the Ring app to deliver real-time smoke and CO notifications to your smartphone. This Costco value pack includes two detectors, each measuring 5 inches in diameter and 2 inches in height with a 3.3-inch mounting plate diameter. The units require AC 120V hardwired installation and include battery backup for use during power outages.

These alarms feature dual-sensor technology for both smoke and carbon monoxide detection and connect to your home's 2.4 GHz Wi-Fi network during setup. Whole-home smart connectivity means that adding just one Kidde smart alarm to your hardwired system sends mobile alerts for every interconnected alarm in the home. When one alarm sounds, all interconnected alarms sound simultaneously. The advanced sensing technology delivers smoke detection over 25% faster than leading competitor 8th Edition products, with up to 3x more precision to reduce false alarms.

The Ring app (iOS 14+ or Android 9+) enables remote monitoring, alarm status checks, the ability to silence alarms remotely, and early low-battery warnings. Multi-user access allows household members to share device alerts. The detectors are also compatible with Amazon Alexa for voice-based status queries. An optional Ring subscription adds 24/7 professional smoke and CO monitoring with emergency response for $5 per month after a free 30-day trial.
