- ↑ Arrow keys are currently unsupported since they're only used for functions that are local to a physical DSC keypad.
- ↑ Zones on expanders are reported instantly. Built-in zones are not tracked internally and must be tracked using another algorithm. See the zonetracking module in the alarmdecoder Python library.
- ↑ All zones are reported via EXP messages on DSC panels.
