FAQ

1. What exactly does the VASAIKO 6-in-1 Smart Guardian detect? Our flagship device is a comprehensive air quality hub. It monitors Carbon Monoxide (CO), Combustible Gas (Natural Gas, Propane, Methane), Smoke, Temperature, Humidity, and Water Leaks. It’s designed to be your all-in-one safety sentinel.

2. Is this a plug-in device or does it run on batteries? It offers the best of both worlds. The device primarily operates via a standard US wall plug (NEMA 5-15) for continuous 24/7 monitoring. However, it features a built-in rechargeable backup battery that provides up to 10 hours of protection during power outages or while transitioning between locations.

3. How loud is the alarm? Will I hear it from another room? Yes. The VASAIKO Smart Guardian features a high-intensity, 85-decibel alarm. It is specifically engineered to wake even the deepest sleepers and can be heard clearly throughout a standard home or RV.

4. What does the "PPM" reading on the screen mean? PPM stands for Parts Per Million. It measures the concentration of Carbon Monoxide in the air. While traditional alarms stay silent until levels are dangerous, VASAIKO shows you the exact number in real-time. Seeing a "000 PPM" means your air is perfectly clear.

5. How long do the sensors last? Do I need to replace the unit? We use professional-grade sensors with a 10-year lifespan. While the device is built for long-term durability, we recommend testing your unit monthly using the "Test" button and replacing the entire unit every 10 years to ensure maximum sensor sensitivity.

6. Can I use this in my RV or when I’m traveling in an Airbnb? Absolutely. In fact, that’s what we’re known for. Its compact design and magnetic base make it perfect for RV interiors, hotel rooms, and vacation rentals. It’s the ultimate "peace of mind" gadget for travelers.

7. Does the device meet U.S. safety standards? Yes. Our sensors are engineered to meet or exceed UL 2034 (Carbon Monoxide) and UL 217 (Smoke) safety standards, ensuring you receive professional-grade protection that complies with American safety regulations.

8. What kind of warranty do you offer? We provide a 1-year comprehensive manufacturer warranty and a lifetime of technical support. If you ever have a question about your readings or device function, our US-based support team is just an email away.

9. Why is VASAIKO better than a $15 alarm from a big-box store? Traditional cheap alarms are "black boxes"—you have no idea if they are actually working until they fail or beep. VASAIKO provides active monitoring. With our high-resolution TFT color display, you get visual confirmation of your safety, plus 5 additional sensors (gas, smoke, temp, etc.) that cheap units simply don't have.

10. At what PPM level does the CO alarm trigger? Following safety guidelines, the alarm will trigger based on concentration over time:

• 30 PPM: Warning icon appears (Visual Alert).
• 50 PPM: Alarm sounds if detected for 60-90 minutes.
• 100 PPM: Alarm sounds if detected for 10-40 minutes.
• 300+ PPM: Instant high-decibel alarm. This tiered approach prevents false alarms while ensuring instant reaction to life-threatening levels.
