Vista 20P questions

[Del91574]

i looked at the connected wires and all colors are right, yellow and green are matching on the panel. i am using the premade pigtail that comes with the exp boards so its plug in on one side and hard wire to the vista. The exp boards came with 2k and i think 6.5k. so i had to buy the 1k for hard wire. the panel has no power problems and they are stacked right next to each other. i am going to spend more time today and see what i can find.

Whoa right there.

Something isn't adding up. New units come with all the appropriate hardware for installation, not requiring you to source them yourself locally. The value resistors you are posting are very wrong for a 4219/4229 expander. They sound more appropriate for a 20P zone doubling kit. Something makes me think you purchased someone else's problem hardware, with missing hardware, etc.

First, where did the units come from? New in sealed boxes?

Second, what zone(s) are being used on the panel?

Third, have the circuits and resistors been verified for appropriate value? I personally don't trust anything or anyone from "The 'Shack" anymore. What color bands are on the resistors?

Fourth, have you metered out both the power and data screw terminals on the expanders? What sorts of readings are you getting on them? Have you tried using a short piece of wire straight to the panel?

Have you metered out voltage on the protective zones? What sort of values are you getting?

They are set to aw. The 1k eol was a 1/4 ohm, could that be the problem?

1K=1000 ohms. 1/4 ohm is almost a dead short.

I believe he meant 1/4W.

Sorry, I must have forgotten to move to page 2 because I obviously missed half the conversation.

well haveing a new born has made it very hard on time these few days, so i have not had to much hands on yet. one thing i did just to check the exp board, removed all wires and just looped the 1k's and that changed the exp vault and now i just have an erorr on the panel. i think i am getting closer! I read that if any zones are not correct, that it will play hell on trouble shoting and that seems to be the case.

The best thing, if you're suspecting the panel or hardware, would be to dig out a DMM and meter the loop's resistance or voltage (voltage is better, as it'll tell you more of what is really going on).

If you're really not sure of what you're doing, then setting the panel up as a bootstrap and getting a green ready light would be a first way to start prior to connecting your field wiring, then doing that and verifying via a DMM what voltages the zones are sitting at, since that'll give an idea of what you have going on irregardless of how the panel's programmed.
