RV duty propane, CO, and smoke detectors

My detectors are hard wired into the 12V system of the camper, on the same circuit as the overhead lights.

Even when plugged into shore power, one of the detectors starts beeping about low voltage while the water pump is cycling rapidly, such as when I'm taking a shower.

Normally I remove the fuse for the detectors and lights while I shower, and replace it immediately thereafter. This makes for an interesting time when I'm showering after the sun goes down. Either I fumble around in the dark, or I listen to the detectors go beep-beep-beep the entire time.

The detectors are all 15 years old and probably should be replaced anyway, so I'm thinking of killing two birds with one stone. Get some new detectors that use 9V batteries, and get them off the 12V system, and my case.

Any recommendations for good detectors?

    How far down is the voltage going when this happens ?

    If you are going to replace them all just because you think it's time anyway.....I think you should stick with the 12 V ones like it came with. Much more reliable. What if the 9 V model runs the battery down while the RV is in storage; will you know it the next time it's used ??
