UxmCruxial 2-in-1 Smoke & Carbon Monoxide Detector with Display | 85dB Alarm, Replaceable Battery

Two-in-One Protection for Safer Spaces

The UxmCruxial Smoke Detector Carbon Monoxide Detector Combo combines fire and CO safety in a single, easy-to-install unit. It integrates a photoelectric smoke sensor with an electrochemical CO sensor, delivering a coordinated alert system that helps you notice trouble early. This 2-in-1 device is designed to meet UL 217 and UL 2034 safety standards, offering dependable protection for homes, small offices, and shared living spaces without adding clutter.

Dual Sensor Reliability

With two distinct sensing technologies working together, the unit provides robust detection with a faster response time. The photoelectric sensor targets smoldering smoke, while the electrochemical CO sensor monitors carbon monoxide levels, helping you stay informed as conditions evolve.

• Photoelectric smoke detection for smoky or smoldering environments
• Electrochemical CO detection for real-time gas monitoring

Clear Monitoring at a Glance

The built-in LCD displays battery status and real-time CO levels in parts per million. In typical standby, CO concentration isn’t shown, and the green LED pulses every 60 seconds to indicate readiness. If CO is detected, the red indicator flashes, and a blue light may flash if multiple threats are present. These visual cues help you assess the situation quickly without chasing numbers on a screen.

Test, Silence, and Strong Alarm

A dedicated test button lets you confirm operation with a quick weekly check. The alarm is loud and designed to be heard clearly from several rooms, providing audible alert when danger is detected.

• Test mode to verify functionality
• 85 dB alarm at 3 meters for conspicuous alerts
• One-second mute for non-emergency false alarms

Easy Setup for Any Space

Powered by replaceable batteries (3 AA, not included), this unit mounts quickly on a wall or ceiling with the included bracket, screws, and anchors. The design accommodates ceiling placement, which is often recommended for CO placement and optimal smoke detection coverage.

• Battery-powered for flexible placement
• Includes mounting bracket, screws, and anchors
• Ceiling or wall installation guidance to suit your room layout

Real-World Scenarios

Use it in kitchens, offices, bedrooms, or living areas where quick, at-a-glance information matters. The dual-sensor approach and the display help you stay aware of evolving conditions, while the replaceable battery option keeps maintenance simple and predictable.

Important Notes

• Battery requirements are 3 AA cells (not supplied)
• CO is lighter than air; install on or near the ceiling for optimal coverage
