In this video, Michael from Alarm Grid shows you how to set the Installer Code on an Interlogix Simon XT Security System back to its default. For reference, the default Installer Code on an Interlogix Simon XT is 4321. This is also the same default Dealer Code for the system. The only way to have both the Installer Code and the Dealer Code as the same code entry on a Simon XT is to keep them at their identical default of 4321.

Once you change one of the codes, then you can't change it back to its 4321 default as long as the other code (the Installer Code or the Dealer Code) is still set at 4321. The system will not let you manually set two (2) codes to have the same entry. The only way that this rule does not apply is if you keep both codes at their defaults and do not change them. If you do change either code, then the only way to reset them both back to 4321 is to perform a full factory reset for the system. However, it is important to note that the Dealer Code will only revert to its 4321 default after a system factory default if the Phone Lock setting is turned OFF, which is the default selection. But if Phone Lock is ON, then only the Installer Code will revert to 4321 after a factory default reset.

Keeping in the Installer Code and the Dealer Code at their 4321 default is recommended by Alarm Grid. Even if you lose one of these codes and forget them, you can always look them up later on if they are kept at their default values. Furthermore, it is not a security risk if an intruder knows one of these codes. The Installer Code and the Dealer Code cannot be used to disarm the system. If an intruder tries to disarm the system with one of these codes, then nothing will happen. They must have the Master Code or a valid user code to successfully disarm the Interlogix Simon XT Security System.


Hi DIYers, this is Michael from AlarmGrid, and today, I'm going to be showing you how to restore your Installer Code on your Interlogix, or GE Simon XT security system, back to its default setting. So first and foremost, the default Installer Code on an Interlogix Simon XT security system is 4, 3, 2, 1. That's also the default dealer code for our Simon XT security system. When you first open the system from its box, take it out, probably been a while because this is a fairly old system. But it has a default Installer Code, and a default dealer code of 4, 3, 2, 1. And the only way that it can share the same Installer Code and default, the only way that it can share the same Installer Code and dealer code is to have it at its default setting of 4, 3, 2, 1. Once you change the code, say I change the Installer Code to something else, I don't know, 7, 7, 7, 7, then I try to change it back to, 4 3, 2, 1, that won't work, because the dealer code is still using 4, 3, 2, 1. So I would have to change the dealer code away from its default, and then change the Installer Code to 4 3, 2, 1, but then I wouldn't be able to get the dealer code back there, so the only way is if you have them both at the default. And if you need to get it there, then you can factory default the system. I'm not going to do the factory defaulting process in this video, but I will tell you. To do it, you want to power down the system completely. You have to open up the panel, unplug the backup battery, unplug the transformer from the wall outlet, or whatever outlet that is in, and power down the system completely. And as you are powering it back on, you have to be holding down these front four buttons, the doors, and windows, motions, disarm, and status. So it's probably helpful to have a friend or someone else help you out. Someone plug in the system to power it on, and the other person holding down the buttons as you do it. And just one thing, there is a phone lock setting, which is off by default, but if it is turned on, then the dealer code won't reset, so it will still be whatever it's at. So if you want to reset the dealer code as well as the Installer Code, then make sure the phone lock setting is off. But the other main way that you're going to set the Installer Code back to default is to just change it manually. Just to going into programming, which I'm going to show you here, and you go in, you change the code back. That's really what you're going to do in most cases, because a factory defaulting will mean having to reprogram the system from scratch. And I do want to say that it's not a security risk to keep your Installer Code at the default. In fact, we recommend it, we strongly recommend that you keep your Installer Code, in your Interlogix Simon XT at its default of 4, 3, 2, 1. That way even if you forget that code of, 4, 3, 2, 1, you can always look it up, and you can get into programming with that. If you don't have the code, you're pretty much locked out of programming. And I do want to show you that having the code at its default, it's not a security risk, and I'll demonstrate that right now real quick. Actually, we'll wait till the end to do that. I'm going to show you how to actually do that, how to change the code, because that's why we're all here. So you see we're at the main screen of our Interlogix Simon XT. What I can do is I can scroll through this settings using the Arrow buttons. I can also use the down arrow if I wanted to. And I'm going to go into the system programming. And once we're at system programming, we press OK. And then it's going to ask us for our code, which we have to have the Installer Code to get in. So we're going to do our default code. I didn't do it fast enough there. We're going to try that again. We'll go down to programming. And then we're going to very quickly, 4, 3, 2, 1, and we have to press OK to confirm it, and now we're in programming. So let's choose Access codes. And you see, we have some options here, we have our dealer code. We can change the length of codes, so we have an optional duress code that we could use in emergency situations, and some user codes here, I probably should have went the other way, because it's going to be the very last code that we get to. There's the Installer Code, 4, 3, 2, 1. Now I'm not going to change it here because I don't want to take it off of defaults, because then I would have to factory reset the system, and it would be fairly inconvenient. But if I press it, it's flashing, indicating that's right we changed. Going to enter it again, 4, 3, 2, 1, and I press OK. And then that is how I would change the code. I've confirmed it. It's no longer blinking. But if I want to change a different code for instance, I wanted to use your code 1, I could press on that, and now it's flashing. And I'll do, 8, 8, 8, 8, just for an example, and hey, we have a whole new user code in our Simon XT now. So that's how you go about changing the code. The only other way, like I said, would be to factory default the system, which I don't want to do that because that would be inconvenient, but now that we're done here in our access codes menu, I can get out of it by repeatedly pressing this Status button until we're back at our good home screen right here. Now just to show you that it's not a security risk to keep the Installer Code or the dealer code at the default setting. And you saw that our Master Code is 1,2,3,4. Let's try a few things. So let's arm the system. You just press the doors, and windows button just like that, and our doors and windows armed. I can also arm for motions as well, pretty interesting way that the system is armed. But our system is armed now. And let's see. Let's re-entering 4, 3, 2, 1. You see that nothing happens. We didn't get anywhere with that. Let's try our new code, that we just programmed, 8, 8, 8, 8, and you see that the system is disarmed. We used a program code that does have the authority to disarm the system. And we disarmed the system because it says so right there. So one more time, just to make it very clear, this time we're only arming for doors and windows, I guess. But if we do 4, 3, 2, 1, nothing happens. Our Installer Code cannot disarm the system. It doesn't have that authority. Even if an intruder knew that code, it wouldn't help them out. But we enter in our Master Code, 1, 2, 3, 4, and we get the disarm message right there. So just one more time, if I scroll through the settings and I get to programming and use our Installer Code to get in, and I press OK, then I do access codes, and then you see we have the option Installer Code right there. I can press OK. And I can change it, but I'm just going to do, 4, 3, 2, 1, again. And remember, if I were to change it, or I were to change the dealer code, then, I would have to factory reset the system because only one code can use, one code entry, which if we have the 4, 3, 2, 1 here, but both the Installer Code, and the dealer code have it by default, but if I change one, then got to reset to do it, so I can't have them share the same code. I know that's a lot to take in. But let's exit programming here. And so that's how you restore the Installer Code on your Simon XT back to its default setting. You go into programming, change it back through there, or you can do a factory reset, which again, power down the system completely, and as you're powering back on, be holding down these front four buttons. So probably have someone else help you out with that.
