Nắp Che Dây Báo Khói Cho RV

We have a 2007 Fleetwood / Coleman popup tent-trailer. The tent trailer had, at one time, a 12v wired smoke alarm but by the time we owned it, the wired smoke alarm had been replaced with a battery operated one. I recently repurposed the old 12v wire to power a small fan. This model is a cover and spacer for the wire that also allows a Fire Sentry / Kidde i9040 smoke alarm to still be mounted to it--these are less expensive/micro profile 9v fire alarms available at big box stores.

Sharing this model in case others find it useful.
