Anybody here install access control systems? Specifically Honeywell pass point plus. I have an ademco 6139 keypad that I cannot clear the open circuit fault, despite the fact I have entered the correct code of 00 and every other code up to code 31. The main logic board on this system cannot be communicated with by my pc. This all occured after updating the firmware, which completed correctly. any help is appreciated.
Thanks
Ron
