Alarm areas variable

Alarm areas variable

hi 
I have 2 cases in the alarm area
case A for normal 
case B for alarm

the result in alarm areas variable is :
default  = 0
normal = 2
alarm = 7 

my question is that I want just 2 status 
normal = 2
alarm = 7 

Can I delete the default value, or can I change the result in the default value from 0 to 2
