Best practice ZigBee initial network
start-up procedure
In order to avoid creating orphan devices / nodes
/ controllers and moving about devices / nodes /
controllers during the initial network start-up, it is
recommended that the same power up sequence initially
used for the survey be used.
Please note that once a device / node / controller has
been assigned a ZigBee address and has joined the
active ZigBee network, it will save it’s assigned ZigBee
address to flash memory and re-use it afterwards even
after a power failure or a network re-start. The ONLY time
device / node / controller would require a NEW ZigBee
address is if the network is re-started with either a new
PAN ID or a new Channel value. This causes the currently
assigned and saved ZigBee address in flash to be erased
and will force the / node / controller to try to re-join a

5. Leave survey tool B at this location and move survey
tool A towards the other clusters of controllers.
Locate the boundary where the signal strength is
about 20%. This represents the maximum radius
of the second hop where connectivity is possible
based on the building environment and partition
construction.
6. Repeat the process until you establish the maximum
range covered by 5 hops where the last position
recorded represents the “safest” furthest position
that can be covered by a single Jace – coordinator
(fig. 14).
7. If more than 5 devices / nodes / controllers are
present in the same area where readings were taken,
IT IS RECOMMENDED that another Jace coordinator
be used (fig. 15).
