12V Combustible Gas Leak Detector Alarm for Home & RV

Reliable 12V Combustible Gas Detector for Home, RV and Boat

This 12V combustible gas detector provides clear, audible warning when flammable gas is detected, helping you protect people and property in homes, RVs, boats and small commercial spaces. Designed for fixed wall mounting, it operates on a stable DC 12V supply and continuously monitors the air for dangerous gas concentrations.

With a rated power of 3W, typical static current of ≤90 mA and alarm current of ≤100 mA, it offers efficient, low‑power operation for 12V systems. The detector is calibrated to trigger at 10% LEL (Lower Explosive Limit), providing early warning before gas levels become critical. When an alarm condition is reached, it emits an 85 dB sound (at 1 m) and activates a bright red LED indicator for both audible and visual notification. Suitable for environments from -10°C to +50°C and up to 95% RH, it is well‑suited for kitchens, cabins and engine-adjacent living areas.

Why It's a Smart Choice

• Early warning at 10% LEL - Detects combustible gas before it reaches hazardous levels, allowing time to ventilate and shut off supply.
• Clear audible and visual alerts - 85 dB alarm and red LED flash ensure the warning is easy to notice, even in noisy environments.
• Versatile 12V installation - Works with DC 12V systems commonly found in RVs, boats and off‑grid setups, and can also be integrated into home low‑voltage systems.

FAQ

Q: Which gases does this detector sense?
A: It is designed for combustible gases such as LPG/propane, natural gas and similar flammable gas vapors.

Q: Can it operate as a standalone unit?
A: Yes. When powered by a stable 12V DC source, it functions as a standalone wall‑mounted gas alarm.

Q: Where should I install it?
A: Install it on a wall in areas where gas could accumulate, such as near gas appliances, in RV kitchens or in cabins near gas lines, following local installation guidelines.

Q: Is professional installation required?
A: It can be installed by competent users familiar with 12V wiring, but professional installation is recommended to ensure correct placement and reliable operation.
