Title: Concord security panel install code retrieval from MI24LC256 EEPROM
Post by: allanfan on November 23, 2025, 02:16:27 am

Hi all, I'm trying to get install code for my Concord security panel. I was able to use a EEPROM reader to get the attached dump from the MI24LC256 chip.
but I'm not sure where is the install code/dealer code, etc.
seems most search on Internet says 0x03E5-6 & 0x03E2-3  should be the location, but I'm not seeing sensible data there.
Any help appreciated! thank you!
