Sub Engineer
Default: 2222
The sub-engineer code allows limited access to selected parameters from the engineer
programming menu.
We recommend changing the factory default to a code unique to the main panel and/or to
those who may serve as sub-engineers in your ARC, as described in the following procedure.
The Sub‐Engineer is prohibited to access the following parameters:
Default Enable
Code Length
Engineer Code
Communication menu.
Code Length
The Code Length specifies the number of digits (either 4 or 6) for the Grand Master and
Master codes. All the other codes (User, Set Only and Maid) use from one digit up to a
maximum of six digits.
Note:
When you change the code length parameter, all user codes are deleted and must be re-
programmed or downloaded.
For a 6-digit Code Length system, 4-digit default codes like 1-2-3-4 (Grand Master), 1-1-1-1
(Engineer), and 2-2-2-2 (Sub-Engineer) become 1-2-3-4-0-0, 1-1-1-1-0-0, and 2-2-2-2-0-0,
respectively.
If you change the Code Length back to 4 digits, the system codes are restored to the default 4-
digit codes.
EN 50131 Note:
All code length are 4 digits: xxxx
For each digit 0‐9 can be used
All codes from 0001 to 9999 are acceptable
Invalid codes cannot be created since after 4 digits are input, the "Enter" is automatic.
Codes are rejected when trying to create a code that does not exist.
