Q:"What is the minimum battery voltage, below the nominal 12 Volts, that the
Safe-T-Alert SM-STA-30-441RV requires for operation?" Thanks. Craig.
Answer: This propane gas alarm for recreational vehicles requires at least 7 volts to operate. This is the slim line surface mount unit with a case that measures 6"W x 1.875"H x 1.5"D. If you have the room, you might want to consider the
Safe-T-Alert 40-441RV as this propane alarm operates on 6 volts to 16 volts with a very low current draw of 46 milliamp (0.046 amp.).
Hope this helps with your decision.
Sincerely, Barbara
