I need to replace the CO/LP detector in our camper. The current unit is a Safe-T-Alert 70-742 and I'm having difficulty narrowing in on the proper replacement. Have any of you replaced this same ...
I'm confused on how these dual purpose units work, as CO is lighter than air is why my CO detector came mounted near the ceiling in my bedroom, but LP is heavier than air is why my LP detector came mounted near the floor just inside of the entrance door. How does a dual unit read both, correctly if mounted in one spot. No need to remind me how smart I'm not, I already know that. ;)
