Élan TS2. And it's bark. I can take out the low voltage retro ring and use something else if I need to.
Bark...cork wall covering? Or brick, DYAC?
I THINK this fits a double gang box:
STI-7511E
[Link: sti-usa.com]The similar 7511B includes an enclosed double gang back box.
Maybe a distributor knows more about these units from STI.
[Link: smarthome-products.com]Or maybe you could call the manufacturer.
I don't know how much of a 'bubble' this cover provides.
