Safe T Alert 20 Series Mini LP Gas Alarm for RVs — 12V Surface-Mount, White, Compact Propane Detector

Compact, 12V-powered propane (LP) gas alarm engineered for RVs and small mobile homes to detect and warn of hazardous propane or methane levels.

This Safe T Alert 20 Series Mini LP Gas Alarm (model 20-441-P-WT) is a surface-mount propane sensor built specifically for confined, mobile living spaces like travel trailers, fifth wheels, truck campers and folding campers. It combines a rugged small footprint with 12-volt DC operation so you can install dependable propane detection without relying on household AC power or frequent battery changes. The unit is designed to perform across a wide temperature range and includes a mute/vent feature for safer, controlled clearance if a non-critical alarm activates.

How does this alarm detect propane in an RV environment?

The sensor monitors ambient air for propane or methane and sounds an audible alarm when levels reach the warning threshold. Its electrochemical/recovery sensing system is tuned to respond quickly to dangerous gas concentrations and then reset after the area is ventilated, unless levels remain elevated.

• Activates at or below 25% LEL (lower explosive limit) for propane or methane
• Fast response sensor designed for mobile indoor spaces
• Alarm mute/vent button allows temporary silencing while clearing the area

What power and installation options does the 20-441-P-WT offer?

This model runs on 12V DC, making it compatible with RV electrical systems without needing AC power or disposable batteries. Its compact surface-mount case and included bracket make placement flexible in tight cabinets, ceilings, or wall locations commonly found in RVs.

• Operates at 75 mA @ 12V DC for continuous monitoring
• Compact dimensions: 3.5" W x 2.5" H x 1.25" D for small spaces
• Included mounting bracket simplifies surface installation

Is this alarm built to handle harsh travel conditions?

The Safe T Alert 20 Series is engineered for the vibration, temperature swings and confined spaces typical of RV life. Materials and internal circuitry are specified to function across extreme temperatures so the unit remains active during seasonal trips and in varied climates.

• Operating temperature range: -40°F to +158°F for wide climate tolerance
• Rugged design suited for travel trailers, truck campers, and folding campers
• Durable surface-mount housing resists typical movement and vibration

How does the alarm help you respond when propane is detected?

The built-in audible alert and a mute/vent control let you take measured action if a non-critical event occurs, while the sensor continues to re-evaluate air quality. If propane remains above the alarm threshold after ventilation, the detector will reactivate to warn occupants.

• Audible alarm alerts occupants immediately to evacuate or ventilate
• Mute/vent button allows temporary silencing while clearing the area safely
• Rapid recovery sensor rechecks air and re-triggers if unsafe levels persist

Who is this for: The Safe T Alert 20-441-P-WT Mini LP Gas Alarm is suited for RV owners, fleet managers of recreational vehicles, and anyone who needs reliable, low-voltage propane detection in compact or mobile living spaces. Choose this unit if you require a purpose-built, surface-mount propane detector that runs off your vehicle's 12V system, fits into tight installations, and is constructed to withstand the temperature and movement demands of travel.
