For fire detection installations that use smoke detectors, powered or non-powered heat detectors,
or CO detectors, use the wiring configuration on the right hand side of Figure 4. These devices
use separate AUX2 output for power. Make sure that the voltage range of the AUX2 output is
compatible with the input voltage range of the detector you are using.

Double end-of-line resistors
If you use DEOL resistors at the end of a zone loop, the second resistor detects if a zone is in alarm,
tampered, or faulted. You can select DEOL supervision only if you are using normally closed devices
or contacts. You can use only one normally closed contact in each zone.
