Key features

• Please Note: XP0H-WN supports wireless interconnection but does not have Wi-Fi
• All Alarms Sound Together: If one alarm detects smoke or CO, all interconnected alarms go off at the same time; everyone in your home knows right away and has more time to get out safely
• Remote Control Without the Climb: Test or silence all interconnected alarms with a remote (sold separately)—no ladders, no reaching; simple, safe, and perfect for seniors
• 10-Year Sealed Lithium Battery: A long-lasting battery that powers your alarm for 10 years, so you don’t have to worry about frequent replacements
• 2-in-1 Protection Made Simple: Smoke and carbon monoxide detection work together in one device to provide nonstop safety you can count on; tested and certified to meet UL 217 and UL 2034 safety standards
• Large Mounting Bracket for a Neat Look: Our oversized 5.7-inch (145 mm) bracket covers a wider area than typical small brackets, hiding old screw holes and ceiling marks from previous alarms; this ensures a clean installation without extra patching (Note: Please confirm your current device fits this size before installing.)
