On each additional WCI as it joins the network.
Note:
Typically, it takes about 10 minutes for a WCI to join the network. However, the time is
dependent on the distance between the WCIs in network as well as the size and type of
structures that may exist between them.
5. After the network is formed, press the OPEN_NET button on the coordinator to close the network if it
is still open (indicated by an illuminated OPEN_NET LED).
Task 2: Installing a Tracer SC+ After Network Formation
Before a Tracer SC+ is installed on a previously established network, the network must be
disbanded and then re-established. Follow this procedure:
1. On the WCI that is currently the network coordinator, press the START button for 10 seconds. The
network will disband.
2. Install an addressed WCI on the Tracer SC+ following addressing and wiring instructions (see
After power is restored to the Tracer SC+, the WCI that is installed on the Tracer SC automatically
becomes the network coordinator and a new network is established.
3. Observe the yellow OPEN_NET LED illuminate on the coordinator WCI. This LED remains lit for 1
hour, indicating that the network is open to allow WCIs with matching addresses to join the network
for that duration. After each WCI joins, the 1 hour timer starts over.
Note:
If the network closes because the timer has expired, you can open the network for an
additional hour by pressing the OPEN_NET button on the network coordinator WCI. To
extend time on a network that has not yet closed, press the OPEN_NET button on the
coordinator to close the network, then press it again to open the network for an additional
hour.
4. Observe the green NWK LED illuminate:
•
On the coordinator WCI, indicating that it has joined its own network.
•
On each additional WCI as it joins the network.
Notes:
•
Typically, it takes about 10 minutes for a WCI to join the network. However, the time is
dependent on the distance between the WCIs in network as well as the size and type of
structures that may exist between them.
•
Sensors do not immediately figure out that the old network has been disbanded. They
are asleep to conserve battery power, and they do not display an E2 right away. It can
take up to five minutes for a sensor to detect that the old network is gone, but then they
will display an E2 until they join the new network.
•
The fastest way to get the sensor to join the newly formed network is to Open the
network using TU or pressing the Open Net button on the coordinator, then go to each
sensor and force the sensor to join by pressing the center button twice on WCS-SB/SD
sensors, or pressing the UP arrow once on the WCS-SO, -SCO2, -SB/R sensor. You
may have to repeat the button press a few times before the sensor joins.
5. After the network is formed, press the OPEN_NET button on the coordinator to close the network if it
is still open (indicated by an illuminated OPEN_NET LED).
6. To enable and configure Tracer SC+ for the new wireless network, see Tracer SC Online Help and
the current edition of the
Tracer SC System Controller Installation and Setup
guide (BAS-SVX31*-

Installing Air-Fi Wireless Sensors with BACnet MS/TP or BACnet/IP
Air-Fi Wireless networks normally include network and sensor communication between all WCIs and
WCSs. Other applications include Air-Fi Wireless sensors with BACnet MS/TP or BACnet/IP (hardwired
or Wi-Fi). In those cases, network communication between the Tracer SC+ and unit controllers may be
BACnet MS/TP (hardwired) or BACnet/IP (hardwired or Wi-Fi). With the addition of WCIs on each unit
controller, Air-Fi wireless capability enables connectivity to the wireless sensors.
