What does the suffix AABA mean on an EDB?

I need to know how to get an auxiliary contact on my EDB breaker.  

Product line:  
Circuit Breakers

Powerpact EDB, EGB, EJB circuit breakers for the NF panelboards

The AABA suffix includes a 1A1B auxiliary switch and a normally-open alarm switch.  We do not offer an auxiliary contact for these breakers without an alarm switch.
