I’m migrating from a Vista 20P that has wired motion and door contacts. I see a number of these wired sensors have resistors in series on their comms terminals.
Should I keep the resistors as is when reconnecting the old sensors to the new IQ Hardwire PowerG?
See page 12 about supervision and EOL resistors. Although if the EOL resistors are at the panel and not at the end of the line then they aren’t really providing supervision.
Hi @heisendoggie, thank you for the info. I ended up keeping the resistors as installed by ADT on the Vista 20P and transferred them to the PowerG. Since they’re all working as normal, I’ll keep them.
