M1DBH w/External 12VDC

[Yann Debonne]

Hi,

I’ve got an Elk M1Gold installation that has an M1DBH. I built a casitas 300′ away. I’m thinking of merely adding another M1DBH in the casitas to use for a keypad and two more input expanders to handle the zones in the casitas.

My question is, 12VDC over 300′ of CAT6 from main house M1DBH to casitas M1DBH is a bit of an ask.  Won’t the 300′ cross over cable to carry the needed 12VDC to the second M1DBH have significant voltage drop?

Any thoughts?

Thank you,

Yann

I would suggest NOT connecting the Brown (+12VDC) in the crossover cable from the first M1DBH to the second M1DBH and then powering the second M1DBH locally.

Thank you Brad.  If the M1DBH doesn’t care where it’s 12VDC is coming from (CAT6 or board terminal), then that’s what I’ll do.
