X-Sense SC01 Smoke and Carbon Monoxide Detector 1-Pack — 10-Year Sealed Battery, Photoelectric + CO Sensor

The X-Sense SC01 is a combined smoke and carbon monoxide alarm with a sealed 10-year lithium battery, designed for straightforward wall or ceiling installation to provide long-term detection without rewiring.

Compact and self-contained, the SC01 pairs photoelectric smoke sensing with an electrochemical CO sensor to monitor two hazards from a single device. It’s a basic standalone unit intended for homeowners or renters who want reliable detection without networking features — note it isn’t Wi‑Fi enabled and won’t interconnect wirelessly with other alarms (see SC01-W for interconnect models).

How does the SC01 detect both smoke and carbon monoxide?

The SC01 uses two dedicated sensors: a photoelectric chamber tuned for smoldering, smoky fires and an electrochemical CO sensor for low-level carbon monoxide detection. Each sensor triggers the unit’s 85 dB alarm when readings exceed safety thresholds, helping occupants notice and respond.

• Photoelectric sensor reduces nuisance triggers from cooking smoke.
• Electrochemical CO sensor accurately senses colorless, odorless CO gas.
• Integrated processing analyzes signals from both sensors before alarm activation.
• Audible 85 dB siren alerts nearby occupants for prompt attention.

What do I need to know about power and maintenance?

The SC01 is powered by a factory-installed sealed lithium battery rated to last the full 10-year service life of the alarm, eliminating yearly battery changes. The unit will chirp at end-of-life or if a fault is detected, prompting replacement of the entire device per manufacturer guidance.

• Sealed 10‑year lithium battery included; no battery swaps required.
• End-of-life notification to replace the unit after its service life.
• Simple weekly test button verifies alarm and sensor function.
• No AC wiring — prevents accidental miswiring during installation.

How easy is installation and placement?

The SC01 mounts to ceilings or walls using the included bracket, screws, and anchor plugs, so no electrician is required. Because it’s a standalone battery-powered unit, you can position it where detection is most useful without routing power or network cables.

• Includes mounting bracket, screws, and anchor plugs for quick setup.
• Works on ceilings and walls; follow local codes for optimal placement.
• Lightweight and compact for unobtrusive installation.
• Ideal for living rooms, bedrooms, hallways, or rental properties.

Will the SC01 reduce false alarms from everyday cooking or steam?

The photoelectric smoke sensor in the SC01 is designed to be less sensitive to brief cooking fumes and steam compared with ionization detectors, lowering nuisance alarms. Still, correct placement away from kitchens and bathrooms is recommended to minimize non-hazard alerts.

• Photoelectric technology favors detection of smoky, smoldering fires.
• Avoid mounting directly above stoves, ovens, or showers.
• Follow manufacturer placement guidance to balance sensitivity and nuisance prevention.

Who is this for? The X-Sense SC01 is suited for homeowners, renters, or landlords seeking a low-maintenance, two-in-one safety alarm without the complexity of wireless networks or hardwiring. Choose this model when you want a compact, battery-sealed device that provides combined smoke and CO monitoring for bedrooms, living areas, and hallways, and replace the unit after its 10-year lifespan as indicated.
