Tracer Summit Building Control Units (BCUs), Tracer 100 series building management panels, and Tracker all monitor and coordinate control of Trane HVAC equipment, non-Trane HVAC equipment, and related building systems. A single Integrated Comfort system is created by linking multiple building level control panels via a communications network. Tracer Summit Building Control Unit The Tracer Summit BCU is an intelligent field panel that communicates with multiple Trane Unit Control Modules (UCMs). BCUs can be configured with up to three UCM communication links. ICS Capability The BCU performs a regular communication scan on all UCMS to update information and coordinate control of the building or of building subsystems such as chiller plants. Multiple BCUs and PC Workstations can be connected via the ARCNET LAN. PC Workstations may also connect remotely through modems. The Tracer Summit BCU can be used to provide a connection to Trane UCMS for a BACnet standard protocol interface. This connection may be over RS-232 or the ARCNET LAN. Software Capabilities Application Programs The BCU enables the following building management functions.
BACnet Standard Protocol Compatibility Tracer Summit system communication is based on ASHRAE/ANSI BACnet Standard 135-1995 which standardizes communication between the PC Workstation, BCU, and other BACnet-compatible devices. This enables interoperation with non-Trane building management systems and subsystems. Alarm Processing Tracer Summit software receives alarms from the BCUs. Alarms are prioritized into 20 operator-definable levels, and can be routed to any workstation and printer in the system either on or offsite. Hardware Description Communication Links The BCU has three slots for UCM communication links. These links allow the BCU to communicate with the following UCMs:
