content: Hi, a couple of years ago , I had to hack a DSC alarm and I record the steps and I did a small youtube video to gain access again. Why I hack the alarm, each time that you contract a monitor company they block your alarm and they denied the service to unlock the alarm if you don't sign a contract again with the. They really do not provide a good service and there are other options, as monitor your alarm by yourself. There is a lot of interest in hacking this alarms to regain access to it. But , I don't have time to answer questions and I haven't installed a laboratory in Australia yet. I am going to redirect the question to you guys that love this types of hacks.*******"Hello I have been an alarm installer for about 5 years and having an issue with a ADTPC5020. I'm in the office doing some testing a ADT PC5020 because I have a customer that wants our business but it is locked out with an unknown installer code.I did your trick on a PC5010 and worked great. I got a ADT PC5020 from our storage to test and see if I could get in programming. On both PC5020 "At customers and in office" with it shorted correctly it beeps before I can finish the installer code. I manually locked out the one I'm testing with to see if I could figure it out. The customers is also locked because it clicks 10 times on power-up.It doesn't click 10 times on power up when I have it shorted. With it shorted micro/com, power up and I press * 8 5 0 BEEP!! every time. Both have the 28 pin micro. Any ideas?I did notice that the ADT branded PC5020 I'm testing on in office that when I factory reset "PGM1/Z1" the default installer code is not 5555, 5020 or 5010 it's 6321 which I thought was strange. I know ADT uses this code a lot but as a default after resetting? New to me.Any help will be appreciated, Thanks?"

content: Greetings!I have the good ole PC5010 that was installer locked. I tried the default codes with no luck.I saw the wonderful video and read many comments telling their stories of a great success so I thought I would give it a go.I unplugged the battery.I disconnected the AC at the terminal strip.I have a version of the PC5010 with the 28 pin chip as shown in the video. I connected a wire from COM to pin #25. I actually soldered it on to ensure I wasn't touching other pins.When I re-connected AC power, the SIREN seems to chirp every half second. I do not hear any relays clicking.Not wanting to do any damage, I stopped there.My board is eerily similar to the one in the video.I have only one keypad.It is hooked up to the house phone line but the phone is not in service.Any ideas on this one?Thanks again! You have given me hope!EDIT: Solved!It turns out, I had my telephone line, a zone expander (PC5108), SOMETHING plugged into PGM 2, and an EnvisaLink. 1. I unhooked all of those (not sure if any of them would get in the way) along with the siren and tried again. 2. I'm not sure what I was expecting but I heard NO clicks. I heard the keypad (LCD5501Z) beep so I went up and pressed *8 5010. The Armed light lit up! 3. I kinda panicked so I went down and cut the jumper line. 3. Went back to the keypad and saw it still said armed. 4. I went ahead and pressed 006 and it short-beeped at me. I entered a 4 digit code and it short-beeped at me. That seemed to do it. At this point I noticed it was showing a somewhat different display. The clock was showing and the opened zones were not showing. With some tinkering, I was able to set the time and show the open zones. I was also able to finally get a wireless device that was previously not working to respond. I played around with changing the master code and installer code, documenting everything, and testing the system.
