Establishing the Network
Three Ways to Establish a Wireless Network
A wireless network can established:
•
After a Tracer SC has been installed.
•
Prior to Tracer SC installation.
•
On a network that will not have a Tracer SC installed on it.
Establishing the Network After Tracer SC Installation
If a Tracer SC is installed prior to establishing the wireless network, the WCI that is installed on a
Tracer SC automatically becomes the network coordinator after power is applied to theTracer SC.
If multiple WCIs are installed on a Tracer SC, each WCI forms an independent network for which
it is the coordinator.
Follow this procedure:
1.
Observe the yellow CRD LED on the WCI illuminate to identify the WCI wired to the Tracer SC
as the network coordinator (see
2. 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. As an alternative, you can use Tracer TU to open the network.
3. 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.
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.
4. 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).
5. To enable and configureTracer SC for the new wireless network, seeTracer SC Online Help and
the current edition of the
Tracer SC System Controller Installation and Setup
guide (BAS-
SVX31).
Establishing the Network Prior to Tracer SC Installation or Without Tracer SC Installation
If aTracer SC has not been installed at the time that you are ready to establish the network or will
never
be installed on the network, follow this procedure to establish the network.
Task 1: Activate Communication Among Existing WCIs
1.
Choose a centrally located WCI that has been wired to a unit controller to become the network
coordinator.
Note:
This WCI will be network coordinator temporarily, if the network is to have aTracer SC
installed on it at a later time. At that time, the WCI that is installed on theTracer SC will
become the network coordinator.
2. Press the START button for 5 seconds to establish the WCI as the coordinator and to open the
network for joining. The yellow CRD LED on the WCI illuminates to identify the WCI as the
network coordinator (see
