Hi all,
I've got a question regarding EOL Resistors. I've read the posts regarding them, and believe I understand their purpose, and the correct way to implement them in a zone with a single contact.
But what is the way to correctly install an EOL resistor in a zone with multiple (in my case NC) contacts? Is the method different depending on whether you're wiring each sensor on a home run (and connecting them serially at the panel)?
My plan (for an Elk M1G) is to do home runs on each of the contacts, which I think will give me a maximum of 3 runs in a single zone. The instructions specify a 2200 ohm EOL. Can I divide this by three (~730 ohms) and put one by each contact? I don't hink this will work, because if one leg gets shorted it will still see 1460 ohms which I think will be in the OK range. Am I better off wiring the sensors serially w/o home runs? If I do that, I assume I just put the single EOL at the farthest contact?
Thanks for any advice you can offer.
