The self-forming, self-healing nature of the mesh
network eliminates the need for maintenance as the
environment changes.
To implement the WFLN, a Field Level Network
Transceiver (FLNX) is mounted at the FLN device and
a Field Panel Transceiver (FPX) is mounted at the field
panel. Both must be powered by 24 Vac. The
transceiver antenna can be mounted either directly or
remotely. In cases where the radio transceiver is
mounted in a metal enclosure, the remote mount
antenna would be used. The transceivers are plenum
rated for direct mount without an enclosure.

Figure 3. Field Panel Transceiver (FPX).
Once installed and powered, the transceivers
automatically form the mesh network, and the WFLN’s
wireless mesh communication is virtually transparent
to the system and end user.
The WFLN also supports communications with the
Wireless TEC Room Temperature Sensor (WRTS).
The WRTS can be bound to a specific Terminal
Equipment Controller (TEC). Because the WRTS
utilizes the mesh network, it can either communicate
directly with the FLNX located at its TEC or through
other nearby FLNXs that will route the data to the
appropriate TEC.
Features
• Supports communications with Wireless TEC
Room Temperature Sensors (WRTSs).
• Multiple FPXs (WFLNs) and hard-wired FLN
devices can reside on the same FLN cable.
• Field selectable frequency/channel switch selects
one of 16 channels of operation in the 2.4 GHz
frequency band.
• Field selectable network identification to allow
multiple WFLNs to operate in close proximity at
the same frequency/channel.
• Direct mount or remote mount antennas.
• LED to indicate power and communications.
Wireless Mesh Network
• Self-forming for simple deployment.
• Self-healing for high reliability.
• Bi-directional routing for command and control.
Benefits
• Highly reliable even as the RF environment
changes.
• Provides simpler, faster, and easier installation of
FLNs.
• Minimizes impact to facility and occupants during
installation in retrofit situations.
• Can easily move FLN devices without needing to
reroute network cable.
• Can easily add FLN devices to an existing WFLN.
• Eliminates reliance on old, unreliable, or
incompatible wired infrastructures.
• Allows staged migration for retrofit situations.
