Safe-T-Alert 25-741-BL Mini Dual CO/Propane Alarm 12V Surface Mount Black

The Safe-T-Alert 25-741-BL is a compact, dual-sensor combination alarm that simultaneously detects both Carbon Monoxide (CO) and explosive Propane (LP) gas in a single surface-mount unit. Designed specifically for the rugged RV environment, it delivers reliable, hardwired 12V DC protection without the need for batteries.

Powered by the latest microprocessor technology, the 25 Series features two independent, self-cleaning electronic sensors — one dedicated to CO detection and one to propane — allowing each gas to be monitored simultaneously without cross-interference. A built-in recheck cycle helps prevent false alarms from brief, incidental gas exposure while still alarming immediately when dangerous levels persist.

Key Features:

• Patented Double-Duty Alarm detects both propane gas and carbon monoxide in one unit
• Two independent, self-cleaning sensors operating simultaneously
• Operates on 12V DC hardwire — no batteries required
• Alarm Mute button silences the alert while the RV is being ventilated
• Rapid recovery sensor resets when silenced, reactivates if CO levels remain elevated
• Memory scan retains the CO concentration level that triggered the alarm
• Low voltage warning activates at 7 volts
• Alarms at less than 25% LEL (Lower Explosive Limit) for propane
• Loud 85 dB audible alert at 10 feet
• Nominal current draw: 108 mA at 12 VDC; operational range: 12V ±15%
• Compact surface-mount case: 3.5"W × 2.5"H × 1.25"D
• Listed to UL 1484 RV and UL 2034 RV; meets RVIA/NFPA requirements
• Manufacturer: MTI Industries

The 25-741-BL is the ideal upgrade for any RV currently equipped with a single propane-only alarm, adding critical CO monitoring in the same compact footprint. Recommended replacement interval is 5 years from date of installation per manufacturer guidelines.
