Safe-T-Alert 45 Series 12V Dual LP/CO Alarm — Black Flush Mount (45-742-BL)

This 45 Series alarm detects both propane gas and carbon monoxide in one flush-mount unit, so a single device covers two hazards. It runs on 12-volt power with no batteries to replace, and the mute button silences the alarm while the RV is ventilated — the rapid recovery sensor resets once clear or re-sounds if dangerous levels remain. It replaces Safe-T-Alert Model 40-442 propane alarms and fits Class A motorhomes, van campers, Class C mini-motorhomes, travel trailers and fifth wheels.
