Smoke alarm

its worn out you,ll a new one. they do go bad after a few years.

Not what I wanted to hear the day before a trip. Any way to silence it until I get it replaced?

Remove backup battery and disconnect RV power. Not recommended unless you go to a big box store and buy 9v one for now.

Sounds like it bit the dust. To silence, I have used one of the little elastic bowl covers or put plastic wrap on it. Not very safety wise... just what I have done .

I think I will buy a 9v one at big box until I get this one replaced. To disconnect from RV power do I cut the red wire?

You can cut both wires. Just make sure you cut one, tape it, then cut and tape the other. Don’t cut both at the same time with metal snips or they will short.

The wires attached to the smoke detector are (almost certainly) short, maybe 6", pigtails, and are joined to the RV wiring in the wall or ceiling. You should be able to pull them enough to access the joints and detach there. In my RV they used wire nuts, taped to prevent them from working loose, for all those sorts of connections; but there are a few possible methods that could be done. (I know some will say that wire nuts are no good for RVs, but so far all the wire nut connections in mine have been trouble-free.)

As BB alludes to, make sure you insulate the loose wires somehow or another so they can't short out.

Have you checked the voltage on the HARDWIRED battery wires at the detector. If you have LOST the 12 volts to the Detector, the beeping may indicate THAT and not the low power of a 9 volt battery when you have a 9 volt Battery ONLY detector. Doug

I find that hardwired smoke detectors are unnecessary and often PIA. Suggest you toss and buy an inexpensive battery operated combo fire/CO detector - you have to change the battery once a yr. No big deal.

I agree. We did this too after being annoyed by the hardwired one.
