Installation
1. Determine the optimal location of the FLNX and
antenna for RF communications.
Ideally, the antenna should extend below the
terminal box.
2. Mount the FLNX using the provided screws.
You can also use double-sided tape or
VELCRO
®
fasteners.
3. Set
the
Channel
and
Network ID
switches to
the settings selected for the WFLN.
4. Connect the communication port of the FLN
device to the FLNX (Figure 4). The maximum
cable length is 4000 ft (1219 m).
5. Connect to 24 Vac power (Figure 4).
CAUTION:
If the FLNX shares the power supply with a
Wireless TEC Transceiver (TTX, P/N 550-
205) and the TEC, be sure to use a ground
isolated transformer (P/N 550-710)
between the TTX and the power
transformer.
