How do I add additional user codes to the Lynx Plus L3000?

<Back

User codes on the Honeywell Lynx Plus are numbered 03-08. (02 is the Master Code) This will give you the ability to add up to 6 regular user codes.

To add user codes to the system you will type in your 4-digit Master Code + 8 + (two digit user number) + new code twice.
