I'm in need of a new LP detector to replace my Safe T Alert 40-442P. My friend got a new one that mfg. date was 2 yrs.old when he received it, so on a 5 yr. life he's already down to 3. Where have you...
Both of my detectors started beeping at almost exactly 5 years from the date of having power first connected. I cut the power wires to them while in storage this winter and have new ones to replace them before our first trip out next month.
