I have a Radionics D420/D4112 alarm system in a rental I just bought and there’s no manual with the master code penciled in. Is there a way to create a new master code without making a service call or replacing the main control board? Somewhere on line I found 3 ways to get a new code 1) make a service call, 2) replace the main control board, 3) install a new alarm system. Real helpful. I found all the manuals on line.

Thanks in advance.

I see you not only have a security system that you don't have the code for, but you also have a leaky toilet tank (another thread). I'm sure you'll find more things... Good luck!

Unless you can get the code from a previous owner/renter you're pretty much out-of-luck with that old system. The D4112 required a D5100 bar code programmer to program and setup the system. You may be able to find one, but ...

I would test the system's sensors to determine if they're in working condition. If they are, or can easily be put into good operating condition, I would consider replacing the system panel with a new one and use the existing sensors/wiring. If they're not in working condition, you have a bigger and more costly decision to make.

Thanks for the info even if it's not what I'd hoped for. Looks like I'm up a creek without a paddle. Thanks for the Google effort. That was dead on.
