LP Detector
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...

Just went thru that with units for the house. From what I know now, the time (internal timer) does not start until the unit is powered up either by battery or 12v. So it will still last 5 years.
