How to wire and program System Sensor 4WB series 4 wire smokes detectors on a DSC PowerSeries Neo



Hey guys, Hayden here again from Alarm System Store, and today we're gonna be adding four wire smokes to our DSC Neo system. We're also gonna be adding an EOLR1. And what this is, is a power supervision relay that allows you to monitor power along your smoke chain. You're gonna need a 5.6K ohm resistor at the end of the line. Let's hop over to the table and I'll start wiring it up and show you how it's done.

So for four wire smoke installations you're gonna be using all four of these wires. Now, if we're gonna be using PGM2, we're gonna do Aux + for the red. That's where all of our power comes from. Black is gonna go to PGM2, and these two are going to be our zone wires. So we're just gonna hook them to zone one. So you wanna use your white or yellow for your power or your zone wire, and then the green is going to be your common or your ground.

All right, we're gonna go ahead and start hooking up our smoke detectors. So we got two, four wires here. Now on a smoke detector, you're gonna have multiple terminals. So as you go around clockwise, this very first terminal here is gonna be the power in. Second terminal is gonna be the power out. Third one is gonna be the negative. And then these two are gonna be your zone contact wires. So what we're gonna do is we're gonna take our red wire from the panel and our red wire is gonna go to the power in, black wire is gonna go to the negative and then our two zone contact wires are gonna go to these last two terminals here.

So this is what you should have at the end, after you've wired your first smoke. Now, we're gonna go ahead and hook up our second smoke. So we got our second wire for our second smoke here. So on this one, it's gonna be almost the same, but for our power wire, our red wire, we're gonna be using the second terminal, the power out. So the red wire's gonna go here and then black and then white, green. And then when we connect it to the next one, the power out from this one is gonna go to the power in of the next smoke.

And this is what it's gonna look like as you go down the line of your four wire smokes. So we got our power in from the panel here on this very first terminal, power out is gonna have the red wire going to the second smoke, two blacks, two yellows, two whites, and then two green wires. So now we're gonna wire up the second smoke the same way we did the first. So like I said, red is gonna go on the positive in which is the terminal. Okay. And this is what your second one's gonna look like, just like the first.

Okay. So I went ahead and put a resistor on this as well. You'll have to have a resistor on your four wire smoke here across the two zone terminals. That's a 5.6K resistor for DSC. It's gonna be green, blue, red, and gold. Now, if all you have is just smokes connected, then that's all you're gonna need, this setup right here. Now, what we do recommend putting on your system is this module right here. This is an EOLR1 power supervision relay. What this does is monitors the power that goes to these smokes.

So this resistor works well for watching the zone terminals, but there's no way to monitor power on a four wire smoke because they are separate wires. So I'm going to install this EOLR1. And if power does happen to go out along this circuit, this is gonna catch it and it's gonna set off the trouble for the smoke zone. That way you know if you're losing power. So what I'm gonna do is I'm gonna use a separate wire. So what we have here is just another four wire connection.

We're gonna do the exact same thing we did when we were coming out of this first one. So power's gonna go on the second terminal, negative on the negative terminal, and then your two zone contact wires. I'm also gonna be removing this resistor because it's gonna go in the line on this power supervision relay.

Okay. So we got our two smokes hooked up and we got another wire coming out of the second smoke. So now we're gonna take our four wires and we're gonna connect them to the EOLR1 using the wire nuts that come with it. So red is gonna go to red and black is gonna go to black. The other one, green are gonna go on the two purple wires. Now, if you're using resistors on your green wire, you are gonna want to connect the resistor to the purple wire like so with the wire nut, and then you're gonna wanna connect the other end of the resistor to the green wire. And that is going to give you your resistance for the power supervision relay.

Now, I'm just gonna wrap these up. I'm not actually gonna crimp them or put anything on them. I'm just gonna be simulating. So it's a little bit messy, but you get the idea. Now, what we're gonna do is we're gonna take our smokes. We're gonna go ahead and hook them in. And then we are going to do our programming for setting up the zone and the PGM. So now that we have everything connected, I'm wired up. I actually haven't had this connected to the system yet, so I'll be right back. I'm gonna connect it to the system, power down, plug everything in, and then we'll do the programming.

So now that we're back, I am going to go into the programming. So your *8 installer code 5555 is the default. And then we're gonna go to 001, and we're gonna set up zone one because that's what we have it wired to as a fire zone. So that is gonna be a 008 standard fire. So hit *. We're gonna back out and then we're gonna go to 009. So we connected these to PGM2. So we're gonna scroll over to PGM2, and mine's already set up that way, but you're gonna wanna set it as a 103, which is a sensor reset.

And what that allows you to do is since these are normally open contacts and power is running through them all the time, this allows you to reset your four wire smokes by using a command on the keypad. So since that is set as a sensor reset, I'm gonna hit * and we're gonna back all the way out to the menu or the main screen. And so, as you can see, I don't know, probably be kind of hard to tell, but these green lights are flashing. That means that they are powered on.

Now to do the system sensor reset, it's going to be *72, and it's gonna say output deactivated. Oh, my wires came undone here. That's why that trouble popped up. So as long as those stay connected and your resistor is crimped in line, then you'll be good to go. So now what we're gonna do is simulate power being cut from one of these smokes. So I'm gonna go ahead and cut this red wire here.

So as soon as that power wire was cut, the trouble popped up. So if we check the trouble device faults, oops, get the wrong button. Zone trouble is gonna be a fire trouble. Now, that is because this EOLR1 is telling the system that it does not read full power all the way to the end of the line. If we hooked this up without it, then it would not show anything. So I'm gonna go ahead and do that real quick. You know, I'll be right back.

All right. So I've removed the power supervision relay. And if we take this off real quick, you can see that the power wire is not connected to this last smoke, but no trouble is showing up on the keypad. And that is because the only lines being monitored to these four wire smokes is the zone wiring. So if power... like you can tell that this isn't powered because this light isn't coming on, but it's not actually being monitored. And most people aren't gonna notice a green light that flashes every second, every five seconds not coming on. So the EOLR1 is a great way to monitor your power and make sure that your four wire smokes stay connected no matter what.

So as you can see four-wire smokes, aren't terribly complicated. I hope I explained the power supervision relay well enough. Basically, there's just no way to monitor power on a four-wire smoke. If a line gets cut or shorted in any way you need one of those power supervision relays at the end, so that you can tell whenever something like that has happened.

In the future, we're gonna be coming out with an RRS mod video. And what that is is a reversing relay, basically sets off all your smokes at the same time, as long as they have sounders in them. So that is an available module. And I'm going to link that down in the description after that video is published. So keep an eye out for that if you wanna add that to your system. Otherwise, you guys know what to do, like subscribe, comment, tell us what you want, tell us what you'd like to see and I'll catch you on the next one.
