Tip It's time to check your smoke and CO detectors

[RandyB]

A little seen nor heard item is your smoke detector(s). On my 2017 unit, I had the periodic chirp, alerting me to a low battery. I changed the battery in both units. A few weeks later, I noticed that the little red light that flashes to indicate "all is well and operational" was not flashing. Upon further investigation, the new battery measured low voltage, so I thought I got a bad battery and I bought more and put them in. The detectors lighted properly and pressing the test button, they sounded off as they should. Cool, good for another year...or so I thought. Another few weeks went by and I again noticed no flashing red light for "all is good". OK, that's enough. Time to replace both units, entirely. Big box here I come...

Check your detectors for proper operation. As with most RV components, the OEM purchases by low dollar point. Sometimes, you get what you pay for.

Edit...
Upon further investigation, I find that the unit in the bedroom ceiling is a CO (carbon monoxide) detector. CO detectors have a finite life and this one is there. I'll change the $3 smoke detector that is up front also.

Another edit...
OK, I shoulda investigated first and posted after. What I've found out is not confusing at all (facetiously).
Test button on CO detector 3 beeps = replace unit (malfunction), 4 beeps = OK, 5 beeps = replace unit (reached end of life).
Test button on the smoke detector, 3 beeps = OK.

According to the manual, the smoke detector is "RV approved".

I've heard stories too of new RV owners having plastic tabs still in their smoke detectors awaiting battery activation. Moral is as @RandyB points out, check your detectors. I'm far more comforted with my Nest detectors than the cheap ones Newmar installed. I added two to the basement in addition to the two in the house.
