A friend of mine had the exact same issue with an eBay KP1. He contacted Elk and they provided him one, however I don't know that they "had" to or were just being nice.?
Are these eBay parts "grey" market?
Anyway....
Dunno if there is a "gray market" in this stuff as there is for other things....but this one came pretty much as the original did from my M1G system--just no cable. LCD protector, trim strip protector, same kind of bubble wrap bag, etc. I'm thinking someone parted a system out or as some sort of "house cleaning" or something... It's not uncommon for businesses to fail and sell off their inventories to make a few $$$.
So, I think it' just a matter of procuring the right cable and going on down the installation road. The cool part is that down the road I can put another keypad or 2 or 3 in a couple more places--and not pay the big $$$$$ fee Brinks wanted.
I'll give Elk support a buzz on Monday and see what they can do to help. I'm more than happy to pay for the part and shipping, so I'm sure we'll get it worked out.
