LTEM PA/PV - Wiring to Share Panel Power


In this video, Griffin from Alarm Grid shows the viewer how to wire the LTEM-PA or LTEM-PV so that it gets all its power from the ...


hey diyers Griffith with alarm grid here and today we're going to go over doing the shared power connection method with an ltmpv and the Vista residential system so let's go ahead and let's get to it okay so the tools that we're going to use today for this installation um is some pair wire strippers for stripping the wires and just a small flat tip screwdriver for the screws on the panel and on the communicator itself and then the wire we're going to use is 18 gauge 4 conductor wire okay we're going to assemble the communicator first before we mount it on the panel so here there is usually a little plastic piece that can be broken out and what we're going to put there is we're going to put this little uh threaded piece into this part right here okay and then what this is going to be used for is whenever you mount it on top of the panel you screw this inside of the panel onto this little bracket here to tighten it down so it don't move so let's go ahead and start with wiring on the communicator we're going to start with the black and red wire now on the communicator on the screw terminals you will see plus 9 volts and in gnd which stands for ground my red wire is going to go into the plus 9 volts and my black wire is going to go into the ground connection make sure the ground connection is loose okay I'm going to slide these in here okay we're going to tighten them down okay so the next two wires we're going to concentrate on is the green and white wire now sometimes you may get a four conductor instead of having a white you'll have a yellow wire instead of a white wire the most common one is yellow but today we've got a white one so what we're going to do is we're going to put the green wire into the TX terminal which is labeled with a t in front of the terminal and then the white wire is going to go into the r terminal um connection so the screws are already loose so we're going to make those connections real quick okay we're going to scoot it in here to make sure it's in there so I can be a bit more connection and the screw I'll have a better hold on it okay we're going to put the white in kind of scoot that in there tighten it down okay now what you want to do once you have your wire securely in there you want to make sure to run your wire through this bracket here because that's big that's going to go into the panel and that way the wire will go into the panel as well so that way you can close the lid and close the panel whenever it's securely done we'll leave it like that right there okay so the panel that we're using to demonstrate the connection is a Vista 21ip you're going to use the exact same screw terminals on the 21ip on the Vista 20p and 15p as well now the big difference between the 21ip and the other two is we got a jumper that we need to move from the top and middle pin and bottom middle pin because the 21ip has an internal communicator and if we're no longer using that the system must be powered down removing the AC connection and Battery before moving this pin and the pin is right below the IP port here and you see it's on the top and middle so we're just going to Simply unplug it and you see those three pins and then we're going to move the PIN to the bottom and middle pin this 21ip is now ready to use external communication then what we're going to do next we're going to run our wires into the panel through this hole here we're going to put the metal ring that will help hold the communicator to the metal panel here metal can slide this in there put this on here try not to cross thread it I'm going to tighten that up hand tight as tight as it'll go and then that will hold your communicator onto the panel so now on the panel the screw terminals are labeled we're going to be looking at terminals four five six and seven but on the the residential panels you'll see they're labeled um we're gonna go to terminal four again gnd stands for ground that's going to be your black wire on this one it's labeled Ox so this is 12 volts this is where your red wire will go then of course you will see green for terminal six and then yellow which we don't have a yellow wire we're using the white wire in this case so we're going to start with the I like to get them organized and the way they're going to go I'll start with the red wire and black wire first so as I get them straightened out here gonna hold those in place I'm going to tighten them down okay then again the green terminal six here and then the yellow or white depending on what color you have on your wires okay so now again so the way we have it wired up black goes to terminal four red goes to terminal five green goes to terminal six and yellow or white goes to terminal seven now the main thing is on the communicator it says nine volts but it's able to take 9 volts or 12 volts whenever you do the only time you could use the 12 volts is if you're doing the shared power method because terminals four and five is 12 volts DC a little side note and that's how you connect an ltmpv on shared powered method into a Vista residential system if you have any questions you can send us an email to support or
