Hello all. I am in the need of some help. I have a FireLIte ES-50X and I also have some 16/4 fire alarm wire and I have a Red, Black, Yellow, and Green Conductors. The red and black I know what those are. But the Yellow and the Green Wires I am not totally sure on what those are as far as which are Positive and Negative.
Wires have no polarity until you connect them to something: red is usually positive & black is usually negative. As for green & yellow, I use yellow for negative & green for positive, but you can use them either that way or the other way around, as long as you remember which is which.

They are a pair of 16 gauge wires that you can use for whatever you please. Often it would be for devices that require a separate data connection, such as an annunciator.

Green and yellow are normally not positive and negative, but data in and data out. In this case which color is in or out doesn’t necessarily matter, as long as it matches on the other side. (For the record, black is normally the common for both power and data.)

I just said “positive & negative” since that’s the polarity used when using such wire to connect 2 devices together to power one of them: with keypads & annunciators, yes, usually green & yellow are indeed both for the data connection between the keypad/annunciator & the panel.

Well I know that. But I didn’t think this bundle I got was going to be for data. Or is that Standard fire alarm conductors in the US?
What are you using this bundle for?
I planned on using it for SLC and NAC circuits
You only need two wires for each. If you can remove the green and yellow, I’d do that, or you could use the green and yellow for the slc and the red and black for the nac

That’s true too… but I am thinking of doing Class A for NACs and SLC. This is going to be a new install. It is going to be in a little garage building
Using green and yellow could get confusing for an application like that. I’d recommend using that for an annunciator bus, and use FPLR for the NACs and SLC
