X-Sense SC07 Smoke and Carbon Monoxide Combo Alarm 3-Pack — 10-Year Sealed Battery, Photoelectric + Electrochemical

The X-Sense SC07 is a combined smoke and carbon monoxide alarm that delivers 10 years of sealed-battery protection in a single, easy-to-install unit.

Built for homeowners and renters who want dependable, low-maintenance detection, the SC07 pairs a photoelectric smoke sensor with an electrochemical CO sensor. This 3-pack supplies multiple coverage points without the need for frequent battery swaps or complicated wiring—ideal for bedrooms, hallways, and common areas. Note that the SC07 is a standalone model and does not include wireless interconnect or Wi‑Fi; choose the SC07‑W if you need networked alarms.

How does the SC07 detect both smoke and carbon monoxide?

The SC07 combines two complementary sensing technologies to cover different threats. A photoelectric smoke chamber is tuned to sense smoldering, smoky fires early, while an electrochemical module measures CO gas levels over time. Together they reduce the chance of missing gradual combustion or invisible CO buildup.

• Photoelectric sensor for slow-smoldering fires and reduced cooking false alarms
• Electrochemical CO sensor for accurate carbon monoxide readings
• Distinct audible alerts for smoke and CO to help identify the hazard

What maintenance and power features should I expect?

This model is designed for minimal upkeep: a factory-sealed lithium battery inside the housing powers the unit for its full service life, eliminating periodic battery changes. You still get test and silence buttons for routine checks and nuisance alarm management, plus clear end-of-life indication when replacement is needed.

• 10-year sealed lithium battery—no replacements during service life
• Test and hush buttons for quick functional checks and temporary silencing
• End-of-life alert to prompt timely replacement after the warranty period

How easy is installation and code conformity?

Install the SC07 on a ceiling or wall using the included mounting plate, screws, and anchors—no rewiring, base station, or professional electrician required for most residential installs. The unit carries UL 217 (smoke) and UL 2034 (CO) certifications, which supports code-compliant placement and safety inspections.

• Surface-mount installation with bracket, screws, and anchors included
• UL 217 and UL 2034 certified for recognized safety standards
• Clear labeling to assist with inspections and compliance checks

Will this work with other alarms in my home?

The SC07 is a self-contained alarm and does not support wireless interconnection or Wi‑Fi linking—so each unit operates independently. If you require interconnected alarms that sound all units during a triggered event, select the SC07‑W interconnect-capable model instead.

• Standalone operation: no wireless interconnection on SC07
• Choose SC07‑W for networked alarm capability across multiple units
• Ideal to combine multiple standalone units to increase coverage without interconnect

Who is this for: The X-Sense SC07 3-pack is well suited for homeowners, landlords, and renters who want reliable dual-threat detection with minimal maintenance. It's a practical choice for people outfitting several rooms or levels with UL-certified protection and who prefer a long-life sealed battery over regular battery replacements. For properties that need interconnected alarms or smart-home connectivity, consider the interconnect-capable SC07‑W or other networked models.
