How to wire and program System Sensor 2WB series 2 wire smokes detectors on a DSC PowerSeries Neo.

Hey guys, Hayden here again from AlarmSystemStore. And today we're going to be adding two wire smokes to our DSC Neo system. A couple things to note before we get started. PGM2 is the only output you can put 2-wire smokes on, your allowed up to 18 total 2-wire smoke detectors, and you're going to need a 2.2 k ohm resistor, which is going to be red red, red, gold. That's going to go at the end of the line. So let's hop over to the table and we'll get started.

For two wire smokes, we are going to be using just the red and black wire. The red wire is going to go to the AUX+ terminal. And the black wire is going to go to PGM2.

All right so we're going to hook up our 2-wire smokes now. So on a 2-wire smoke, you're going to have five terminals. And as you go around clockwise, you're going to have a positive in, a positive out and a negative. These two (extra terminals) are for additional relays we're not going to cover in this video.

So what we're going to do is we're going to take our two power wires, red and black from our PGM 2 output and our AUX plus, we're going to connect them to the power in which is the first terminal and the negative, which is the third terminal.

So there's our first smoke hooked up. So now what I'm going to do is I'm going to take the next set of wires and we're going to go from the positive out, which is terminal two and the negative, which is terminal three. And then for those two wires, we are going to connect them the same way we did before. Terminal one power in to the negative.

So this is what they should look like. That's your first smoke. Two wires coming in two going out and that's your last one, 2 wires coming in. Now, since we're running these off a PGM 2, when they are two wire smokes, you do need a resistor. The resistor that you need is a 2.2k ohm resistor. And that is going to go across the power out terminal in the negative. So this is what your final product should look like.

The final smoke in the line is where the resistor is going to go, the end of the line. And that is what it looks like. So now I'm going to connect the actual smoke detectors and we're going to do our programing.

So programing for 2-wire smokes is very simple. All you have to do enter your programming, *8 and your installer code. Default is 5555. Then we're going to go to PGM definitions, which is 009. We're going to select PGM 2 because that is where they need to be. So the only PGM that works with two wire smokes and then we are going to set it as a 2-wire smoke, which is a 104. We're going to hit * and then we're going to hit pound until we back all the way out.

And as you can see, systems good to go to reset your smokes. It's going to be *72, and you're good to go now you got to look for is the green flashing lights on your smokes if they are flashing once every 5 seconds, then you are good to go and that's all there is to it too. Our smokes are very simple and there is one additional module that we can add and that's going to be the reversing relay module.

And I'm going to be doing a video on that very shortly and we will link it in the description whenever it is available. But what that module does is basically sets off all the smokes at the same time. So keep an eye out for that. If you would like to add that, then it is available. Otherwise you guys know what to do.
