Here's a funny one.
Town of Huntington, NY can waive the installation of 120V interconnected
smoke detectors if a listed control panel with fire capability is
installed in a residential occupancy. The kick is the building inspector
says that Residential Code of NY requires tha system be powered by a
non- unpluggable Transformer or 120V! Any one see that in NFPA 72 or 70?
There was some discussion about a guard around a transformer- to prevent
unwarranted removal.
My take is #1 its FPL wiring
            #2 FPL listed transformer or Class 3 is acceptable
( he wants a permanently wired transformer- like a bell tranny!)
My reply was most Manufacturers submit the transformer(plug-in)AND
Control Panel for listing by UL- I violate that by substituting a tranny of
non-listed origin and open up a liability issue!
