Its basically variables on the device that show status related info. The the short values are just abbreviations
dam: detailed arm mode (disarmed, armed, armedinstant, stay, stayinstant, night, nightinstant, force, ready...)
a: alarm (none, active)
Not sure i understand whats odd about the multiswitch status info. The multi switch device has 8 switches that can have a state of on/off... my status area can hold up to 6 items so i show the first 6. For a given device it will implement one or more services... those services all have status metadata.... i've picked the common stuff and put it in the status area... its not meant to be anything more than glance data.
