DSC PC1550 Clasic Series 6 digit code compile ok but keep rebooting

[pansament]

I have managed to determinate that whet i set in sketch "accesCode" my 6 digit arm/disarm code in serial monitor it keeps rebooting.

If code not set everything is ok.

Do i need to configure alarm to work with 4 digit code?
Or what can i modify in sketch to work with 6 digit code?

This is error code from serial monitor:

Later Edit:

Alarm system is not configurable to work with 4 digits access code.

I managet to make this project with VirtualKeyPad-Web but same problem, if i set "accessCode" in sketch keeps rebooting.
If i set first 4 digits in sketch I can arm by presing Arm button and presing last 2 digits of access code.
So the project is working but I need this to work with 6 digits access code so I can control alarm system from Home Assistant.
If I don`t set access code in sketch I can see in Home Assistant Zones and state of system but i cannot control it.
I did not find a way to send code from Home Assistant.
