* Requires an LCP Supervisor on each link (where LCPs are connected) to act as an interface/translator.
†
Some models of CGAF chillers are currently limited to addresses 49–54, which limits the maximum number of devices per link
to 6.
‡
The number of TRS panels supported in a BCU is a function of the number of binary and analog objects defined. Make sure that
the BCU is properly sized (refer to BAS-PRB005-EN, Building Control Unit Sizing for Version 13 Tracer Summit Systems). TRSs
must be configured on communication link 1. TRSs cannot coexist with other UCM types on the same communication link. The
non-isolated Comm3 link must be dedicated solely to the TRS interface and can be located only on communication link 1.
** A maximum of 60 devices per link can be accommodated. With a repeater, the maximum number is increased to 120.
*** For a complete list of controllers, see Chapter 5, Comm5 section.
