This must be an easy fix but I am at a lost. Pulled our 2016 Navion Itasca out of storage to load up for our trip to Colorado and the smoke alarm is beeping every 20 seconds or so. I have replaced the 9v several times. It is hardwired with battery backup. No brand name that I can see anywhere. Reset circuit breakers. Still beeping. Any ideas?. Please.
