Wireless Survey Tools User Guide

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).
