What is the default installer code for the Lynx Plus L3000?
The default installer code for a Honeywell Lynx Plus L3000 is '4112'. The installer code is the one and only code that can get you into the programming sections of the alarm system.
We always recommend that you change the default installer code as any crook worth their salt can research and find this code through any internet search. Pick a number that you can remember and don't use one that you'll be using for a user code.
