● A USB-to-RS-232 adaptor may be needed for UL Listed modems or UL Listed
printers that are not configured for USB communication.

Example ALN Configuration for Smoke Control Applications
The RS-485 ALN does not have the same restrictions as the Ethernet ALN for smoke
control. Namely, Ethernet requires UL listed switches and routers.
The following figure displays a possible ALN configuration for smoke control.
Figure 4: Example ALN Configuration for Smoke Control.
HOA (Hand-Off-Auto) Upgrade Kits
HOA Upgrade Kits are available for PXC Compact Series field panels. HOA Upgrade
Kits are not compatible with Unitary Equipment Controllers (UEC 16 or UEC 24). The
upgrade kits replace PXC Compact covers with new covers equipped with manual
override switches and LEDs for visual feedback at the field panel.
Users can override the default switch assignment or customize the switches to their
desired configuration.
