Video Transcript for Peterson Auxiliary Back Up Alarm Review

Hey, what's going on, Adam here with Etrailer. Today, we're going to take a look at a Peterson back up alarm. So we're going to get about 112 decibels, which is pretty loud, even if people are wearing earmuffs or something like that, they're going to be able to hear this thing. And it is going to be compatible with your 12 and 24 volt DC systems. And also it is going to comply with all those state regulations. As far as mounting goes, you are going to have to get your own mounting hardware.

We're just using a self-tapper and a little washer. The mounting holes are going to be about four and one eighth of an inch apart. And that's from the very center of the hole. And as far as dimensions go, we're going to have about three and one 16th inches tall. It's going to be about four inches deep and about five inches wide.

As far as if it's going to work with your vehicles, a lot of people are asking that literally, if you have a reverse light, which every car will, you're going to be able to use it. All you have to do is just add a wire to that wire that's feeding your reverse light and just splice into it and put that on the positive. And then we just need to find a negative. And we're just using the frame is that that's all you need. So it's going to work with all of your vehicles.

It's just how you want to mount it. It's going to go from car to car. It's always going to change, but if you want to see how we did it, we're going to show you how we mounted it and how we ran our wires and all that kind of stuff. So stick around, we're going to show you. First step is finding the reverse light wire.

So the way to do that is to have somebody go into the back and then what we're going to do is we're going to take our tester and then just check for the wire that has the reverse circuit on. So Brad, you put it in reverse real quick. All right. So that is good. So we know that is the circuit that we want. We already ran this wire. So basically what you can do is you can take the wire that runs to your reverse lights. You can cut it in half, and then you can take another wire and twist that together with one side, put it in here, clamp it down, and then take the other to complete the circuit again. So you have two coming off this way. One goes to here, the other one goes to where it was before, and then the other one's just coming from the body harness. So that's what we did. And you can have it right here. So now we can go ahead and start mounting it up. We do want to find a proper mounting spot for this. So for us, we're going to put it right here. Ideally, we're going to find the wire and put it kind of close there. So we don't have to run so much wires. I mean, we can either mount it like this, or you can mount it like this, but for today we want it to be facing out towards the back because that's we're going when this thing is beeping. So you are going to have to supply your own hardware. So what I'm going to do is just use a little self-tapper. I'm going to utilize these holes we've are already made in our frame, just like that. And we can zip them up. You don't want to do it too tight, but just enough to get it nice and secured, we're going to do the same exact thing for this side. And that is nice and solid. So one thing we are going to need is a wire for our ground. So we want to get some terminals and then of course, whatever mounting hardware you're going to be using, we're using self-tapper, so I just grabbed another one to get the ground. So I'm going to put this on the frame on the other side of the alarm. Zip that in there. So now we can take a nine millimeter socket to loosen these guys up a little bit. And then we're going to have some washers in there. So once we take it off, it's going to make sure that we're going to have one bolt here. And then you have a special little nut that has a little washer on it. So we want to put this on there, tighten that down. I like to just get it hand tight for now, do the same exact thing for the negative. And once it's on there, you can just turn it to tighten it up and you don't want to tighten it too much. Just enough to get a nice connection, just like that. And then we'd go ahead and start cleaning up our wires. If you guys do like clean wire, we do have a lot of wire loom too. So, you wanted to pick some of that up as well to make it look nice and clean. You can do that with each trailer. Now you can go ahead and grab a buddy. That's my buddy up there, his name's Brad. He's going to put it in reverse. And we're going to see if it works. Oh yea, definitely works. We have a lot of different backup alarms here at Etrailer besides the one we just showed you. So we laid them all out and we're going to do a sound test here. So we have all of them laid out and over here, we're going to have a little gauge. So as you can see, once I start talking real loud, it goes up. And when I stop, it goes back down. So this is going to give us an idea of exactly how accurate the decibel ratings are and see which one's the loudest. First one up on our list is going to be the Buyer's Product back up alarm. And this one is supposed to do 102 decibels. So, we got some wires ran and we're rigging this up so we can get it to work on the table here. So I'm going to go ahead and put wires in place, just like that. Let's see exactly how loud it actually is. All right here goes the test. So about 96, 97 decibels and it is a little far away. So right here, it's probably going to be around that 102 decibel mark, which is exactly what it says. So let's move on to the next. This one's going to be a little bit louder, 107, apparently again, Buyers Products. And we're going to connect it up. All right, test number two. We're peeking out about 95, which is kind of the same as the other one. It doesn't have a little bit different tone, so that might have something to do with it. And also we do have it a little farther away, but it is still within that range, in the same ballpark. And that's what we're kind of looking for here. So moving up, we're going to go with the Pollak backup alarms. So this one is going to be about 107 decibels. So let's test it out and see if that's what it is. Testing. Again, kind of going around that 95 decibel range. But again, it's just an app on one of our iPads we keep here in the shop, but it still is pretty loud. But all in all, it's around the same or looking at maybe about eight decibels of difference from what it says and what our gauge is telling us now for the Custer backup alarm, let's go ahead and hook it up. Testing. So not as loud as some of the others that we had about 83 is what we're getting with that. And this one's supposed to be 97. So it's within the range. And now for our Peterson backup alarms, it's going to be about 112 decibels. So it should be a little bit louder than the others. It's reading about 90, but that was a lot louder, I think is because of the little projection that they have in the molding. But this one definitely seems louder, even though it is reading about the same from all of our others, but let's move on. So now we're going to go with the Pollak and this one's going to have different settings. So at its highest setting, it's supposed to be around 112. So let's see if it's any louder than this one. Testing Again about 97, but this one definitely is a lot louder. So I think usually when the housing's a little bit bigger kind of projects, that sounded a little bit more, it makes it a little bit louder. Out of all the ones we tested today, the one I would go with is the Pollak. So this one is my favorite just because we are going to have adjustments on the sides for the decibel output. I added on the 112, but we can make it go to 97 or 107. So this is going to be adjustable and it's extremely heavy duty. It does feel a lot more solid than some of the smaller ones. And typically these are going to go on larger vehicles. So it being compact, isn't really a big deal for me. And if you do want a smaller one, the Buyer's Product is going to be a nice compact little unit. And this is going to be a little bit easier to find a place to put it. So now we're going to do one more time, Brad. Yeah, definitely works, it's super loud and that's pretty much it for a look at the Peterson backup alarm..
