Safe-T-Alert dual detectors sense propane at the floor and CO in the air, run on the RV's 12V so there's nothing to replace, and mute while you air out the coach — re-arming if the hazard is still there. Pick the series that matches the hole in your wall: Mini 25 for retrofits (trim rings cover old screw holes; the relay kit can shut a solenoid), 35 and 45 Series standard units (45-741 replaces the 40-442), and the 85 Series with low-battery and end-of-life warnings.\u003c\/p\u003e\n\u003ch3\u003eOptions\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e25-741-WT\u003c\/strong\u003e — Mini dual LP\/CO, surface mount, white\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e25-742-WT\u003c\/strong\u003e — Mini dual LP\/CO, flush mount, white\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e25-742-BL\u003c\/strong\u003e — Mini dual LP\/CO, flush mount, black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e25-742-WT-TR\u003c\/strong\u003e — Mini dual LP\/CO, flush mount with trim ring, white\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e25-742-BL-TR\u003c\/strong\u003e — Mini dual LP\/CO, flush mount with trim ring, black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e25-742-R-WT-TR-KIT\u003c\/strong\u003e — Professional dual LP\/CO with relay output, flush mount with trim ring, white\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e25-742-R-BL-TR-KIT\u003c\/strong\u003e — Professional dual LP\/CO with relay output, flush mount with trim ring, black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e35-741-WT\u003c\/strong\u003e — 35 Series dual LP\/CO, surface mount, white\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e35-741-BL\u003c\/strong\u003e — 35 Series dual LP\/CO, surface mount, black (2 lb)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e35-742-WT\u003c\/strong\u003e — 35 Series dual LP\/CO, flush mount, white\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e35-742-BL\u003c\/strong\u003e — 35 Series dual LP\/CO, flush mount, black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e35-742-BR\u003c\/strong\u003e — 35 Series dual LP\/CO, flush mount, brown (2 lb)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e45-741-BL\u003c\/strong\u003e — 45 Series dual LP\/CO, surface mount, black — replaces 40-442\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e45-742-WT\u003c\/strong\u003e — 45 Series dual LP\/CO, flush mount, white (2 lb)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e45-742-BL\u003c\/strong\u003e — 45 Series dual LP\/CO, flush mount, black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e85-741-WT-TR\u003c\/strong\u003e — 85 Series dual LP\/CO with trim ring, white — low battery and end-of-life warnings (2 lb)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e85-741-BL-TR\u003c\/strong\u003e — 85 Series dual LP\/CO with trim ring, black (2 lb)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e35-742-R-WT-Kit\u003c\/strong\u003e — 35 Series universal dual LP\/CO with relay output, white kit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e⚠️ Safety device — 12V hardwired, 5-year service life from power-up; replace at end of life.
