ALM?
Request current alarm code information.
Sample Response:

Note: These alarms are additive and may occur in any combination. To decode, use the following list.
Subtract out the largest possible integer first, then the next largest possible integer, and so on.
The integer 16 is the largest possible integer to subtract out, leaving a remainder of 2.
The integer 2 stands alone. Thus Alarm Codes 16 and 2 are now present in the system.
