EM-A-BAC-ET-120
Integrates a Lutron Centralized Lighting Control System
with digital equipment that supports BACnet®
communication over Ethernet
Allows a BACnet® system to read status from a Centralized
Lighting Control System processor.
Allows a BACnet
® system to read status from a Centralized
Lighting Control System Processor in one of two modes:
– Individual zone* control of up to 512 zones.
– Scene selection for up to 500 spaces.
• Uses BACnet® Ethernet protocol only.
• The system is limited to a maximum of 1024 BACnet® points.
System status refresh rate is determined by the number of
spaces or zones that are being monitored. The worst case
delay is 5 minutes for a system with 1000 BACnet® points
that need to be refreshed.
* Lighting Zone Controllers, OMX-3600, SO-SVC, and CCOs cannot be
controlled by zone control.

BACnet® Protocol Implementation Conformance Statement (PICS)
Date: 31 May 2011
Vendor Name: Lutron Electronics Co., Inc.
Product Name: Centralized Lighting Control System BACnet® Integrator
Product Model Number: EM-A-BAC-IP-120, EM-A-BAC-ET-120
Applications Software Version: V6.06p (E) Firmware Revision: V5.22fA (K) BACnet® Protocol Revision: V2.01 bL
Product Description:
Both the EM-A-BAC-IP-120 and EM-A-BAC-ET-120 are gateway interfaces between a BACnet® Building Automation System
and the Lutron® GRAFIK Centralized Lighting Control System. The BACnet® gatateway exports a single BACnet® device with
objects that retrieve the status and perform actions through the Centralized Lighting Control System. The BACnet® gatateway
can interface with either the zones or the spaces dened in a GRAFIK Centralized Lighting Control System. Both zone control
and space control are not possible through the same device. If congured to interface with zones on the GRAFIK Centralized
Lighting Control System, the interface is able to retrieve the relay status and current intensity and set a desired intensity for
each zone in the system. If congured to interface with spaces on the GRAFIK Centralized Lighting Control System, the
interface is able to retrieve the last scene set in the space. The space is controlled by selecting a desired scene. A processor
can only move one EM-A-BAC-IP-120 or EM-A-BAC-ET-120 gateway interface.
