What is the difference between the Master Code and User Code?
Honeywell alarm system. The Master Code is usually the homeowner or business owner’s code. This code, in addition to allowing an individual to arm or disarm a system, allows access to entry level programming, such as changing the clock, date, time and adding or deleting user codes. The User Code is a code most often given to the alarm panel owner’s children, relatives, caretakers, employees, etc. This level of access is used primarily to turn the system on and off. Check with your alarm systems user guide for the exact functions that each level will allow.
