X-Sense Interconnected Smoke and Carbon Monoxide Detector

The X-Sense Interconnected Smoke and Carbon Monoxide Detector is a dual-sensor alarm with a sealed lithium battery designed to last up to 10 years. When one interconnected alarm detects smoke or CO, all linked alarms sound together, helping alert people throughout the home. Its LCD shows real-time CO levels and battery status during alerts or testing; it stays off during normal operation. The battery-operated unit has one-button test and silence controls and a 5.7-inch mounting plate that can cover marks left by some previous alarms. Check that the existing mounting footprint fits before installation.
