Review on 🔥 First Alert SCO500B: Wireless Interconnected Photoelectric Smoke and Carbon Monoxide Combo Alarm with Voice and Location Detection by Jody Kashani

I want them to work. The idea is great: networked wireless fire and carbon monoxide detectors. I bought three. One for each level of my house. It wasn't easy to connect all three devices wirelessly. Sometimes I could connect two but not the third. When I connected the third, one of the first two disconnected. I followed the instructions word for word, but I still only succeeded after a few tries. One unit failed within three months. I called the company and they sent me a replacement. Again several attempts to connect them all. Three months later, one of the devices began to sound an alarm, reporting a false positive result for CO. I removed them all and replaced them with other units from a different company. Since then there have been no problems. They don't work properly. Don't waste your time and money.
