I see Elk has an "official" how-to on connecting a lighted doorbell button (http://www.elkproducts.com/m1-applications-connecting-lighted-doorbell-button-to-m1-zone)
My question is if the resistor is required when using a button that is LED out of the box. I think it is, but wanted to be sure since resistors aren't really readily available anymore (so long, Radio Shack) and I need to get our doorbell up and running ASAP.
EDIT: strike that...found a stash of extra EOLs and resistor math says 2 in parallel should be good. BUT! My question still remains....do LED-out-of-the-box doorbell buttons still need the resistors?
Thanks.
