3. AUX-connection to an Automation or
Security System
The AUX signals can be interpreted in many ways:
1. Simple ON/OFF information for any type of alarm (heat, fire or water leak). This
can be read directly from AUX1 output.
2. Simple ON/OFF information for cooking activity. This can be read directly from
AUX2 output.
3. Simple ON/OFF information for fire extinguishing activity. This can be read
directly when both AUX1 and AUX2 are connected in series to the same line.
4. Four-state output according to the table below. This can be used by reading both
AUX1 and AUX2 separately into the automation system and using internal logic
to decide the state.
