OLUNCLE 4 Pack Smoke & Carbon Monoxide Detectors with Test Button | 85dB Alarm & LCD Display

Enhanced Safety with Dual Sensor Technology

The OLUNCLE 4 Pack combines smoke and carbon monoxide detectors into a versatile, battery operated solution designed for multi room coverage. Equipped with both photoelectric and electrochemical sensors, these devices respond quickly to slow burning fires and CO gas, offering early warning across common living spaces such as bedrooms, kitchens, basements, and garages. While not a promise of protection, the design focuses on timely alerts in daily life scenarios, helping you stay prepared without constant oversight.

Clear CO Readouts and Energy Smart Standby

Each unit features a large LCD display that presents real time carbon monoxide levels when CO is present. In standby, the screen remains off to conserve energy, and a green LED blinks once every 60 seconds to indicate normal operation. This combination allows quick at a glance checks while keeping nighttime disturbance minimal.

Audible and Visual Alerts You Can Trust

In the event of elevated smoke or CO, the detector emits an audible alert louder than 85 dB and flashes a red LED. This multi sensory approach helps you notice a potential hazard even if you are not in the same room. The three indicator lights provide ongoing status cues:

• Green for normal operation
• Red for smoke or CO alerts and low battery
• Yellow to indicate fault status

These signals are designed to be clear and actionable, supporting quick decision making in everyday environments.

Intuitive Testing and Multi Room Coverage

Use the built in test button to verify battery and alarm function, helping ensure the units are ready when needed. The battery operated design supports flexible placement, making them suitable for bedrooms, kitchens, basements, living spaces, and garages. A practical 4 pack enables coverage across multiple rooms for better overall home safety.

What You Get and How to Use It

Included are four detectors that are easy to install in key risk areas. Place them near kitchens and garages where smoke or exhaust may arise, and in sleeping zones where quiet operation is valued. The compact profiles blend into décor while delivering recurring protection with minimal maintenance.

Important Considerations

These detectors rely on battery power for flexible placement and simple setup. They are designed as a proactive layer of household protection and are not a substitute for professional safety equipment. Features are described as potential benefits based on the product design rather than guarantees.
