Power Supply
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!
