Wireless Communications Sensor
(WCS)
Communicates wirelessly to a Tracer
®
unit controller. A
WCS is an alternative to a wired sensor when access and
routing of communication cable are issues. A WCS allows
flexible mounting and relocation.
Wireless Zone Sensor (WZS) Set
A wireless zone sensor (WZS) set (sensor and receiver)
communicates wirelessly to a Tracer
®
unit controller. A
wireless zone sensor set is an alternative to a wired sensor
when access and routing of communication cable are
issues. The sensor allows flexible mounting and
relocation.
Note:
A wireless zone sensor set is not compatible with
an Air-Fi® wireless system.
The Wireless Comm Interface (WCI) enables wireless
communication between system controls, unit controls,
and wireless sensors for the new generation of Trane
control products.The WCI replaces the need for
communication wire in all system applications.

Best Practices Guide
Quantity of WCIs per Network
Each Trane wireless network can have a total of 31 WCIs
(30 member WCIs plus one coordinator WCI). Each
network requires one WCI to function as network
coordinator.
Quantity of Networks per Tracer® SC
A Tracer® SC can support up to eight wireless networks.
Automatic Network Formation
When a WCI is connected to a Tracer® SC, it is auto-
assigned as the coordinator.To enable the coordinator,
Tracer® SC must be configured for wireless
communication.The coordinator WCI opens the network
to allow all WCIs having matching addresses to
automatically join the network. If no Tracer® SC is present,
a centrally located WCI must be designated to act as the
coordinator.You can manually set the coordinator WCI so
all WCIs having matching addresses automatically join the
network.
Wireless Zone Sensors
The WCI also communicates with Trane wireless zone
sensors, eliminating the need for analog receivers.
Wired Zone Sensors
Systems using WCI can also use wired zone sensors.
