WisuAlarm 10-year Sealed Battery Standalone Carbon Monoxide Alarm

10-Year Sealed Lithium Power

The built-in non-replaceable CR123A lithium battery provides a full decade of continuous operation, eliminating the hassle of battery replacements and reducing the risk of low-battery chirps.

High-Sensitivity Electrochemical CO Sensor

Utilizes a Figaro electrochemical sensor for accurate, fast detection of carbon monoxide, capable of alerting at thresholds of 50 ppm (60–90 min), 100 ppm (10–40 min), and 300 ppm (< 3 min).

User-Friendly Display & Controls

Features a backlit LCD screen that shows current CO levels, plus three LED indicators (green, yellow, red) for status, fault, and alarm. A single button supports both testing and silencing.

Home Safety Monitoring

Place the detector in living areas, near bedrooms, or beside gas-fueled appliances (like boilers or water heaters) to continuously monitor CO levels and safeguard against leaks.

Rental Property Protection

Ideal for landlords of apartments, holiday lets, or long-term rentals — provides tenants with easy peace-of-mind without requiring them to worry about battery replacement.

Portable Use During Travel

Compact and standalone: you can bring it to holiday homes, cabins, or even on extended trips — just place it on a shelf or tabletop for immediate protection.

Integrated in Multi-Alarm Systems

Use multiple units across a building to ensure coverage in all key areas, especially in properties where wired options are not feasible.

Safety Backup in Power Outages

Since the alarm runs entirely on a sealed battery, it remains fully operational even during power failures, providing continuous protection when plug-in detectors may be unavailable.
