*>>
You may use any command from the “*>>” prompt. The SALARM bit will go to 1 for one
second for a successful Level 2 access and for three successive bad passwords. In SEL-2020
Communication Processors with I/O boards, you can assign an output contact to SALARM to
allow an external system to monitor for invalid access. In SEL-2020 units without an I/O board,
the SALARM bit is automatically routed to the ALARM contact, causing it to pulse, unless it is
