Establishing a wireless connection
Intensive electrostatic charging processes must be
avoided in applications requiring category 1G/M1 or
EPL Ga/Ma devices (zone 0)!
A maximum of 25 Dräger X-zone 5000 devices may be
connected on a wireless network as otherwise it is not
possible to ensure a reliable connection and alarm
forwarding.
FCC and IC:
This equipment fulfils the requirements specified in
section 15 of the FCC regulations. The following
conditions must be observed for operation:
– The equipment must not generate any harmful
interference and
– Must pick up received interference, even if this
could result in operating errors.
Users must not operate any equipment subjected
to modifications not explicitly approved by Dräger.
The internal/external antennas used with this mobile
transmitter must not be operated in the vicinity of or
together with other antennas or transmitters. Persons
must observe a minimum distance of 20 cm from the
antennas.
This equipment and the corresponding antennas must
not be operated in the vicinity of or together with other
antennas or transmitters.
NOTICE
If the devices are in ON mode, they automatically
establish the wireless connection.
Up to 25 devices can be connected on a wireless
network via a wireless connection.
The typical radio range is up to 100 m in industrial
surroundings (environmental factors may affect the
range).
The devices can be operated in a chain, star or ring
topology. It is possible to establish an open radio
network or independent radio networks. All devices
within radio range are automatically connected.
Open wireless network (standard configuration):
With an open wireless network, any number of Dräger
X-zone 5000 devices (up to 25) can be added to or
removed from a wireless network number.
Independent radio networks:
If independent radio networks are required, different
network numbers need to be assigned for the relevant
radio networks (refer to "Configuring the device" on
page 39).

WARNING
WARNING
CAUTION
Example:
Two independent radio networks each with three
Dräger X-zone 5000 devices should be created. To do this,
the Dräger CC-Vision PC software should be used to set
NET:001 with three Dräger X-zone 5000 devices and
NET:002 for three further Dräger X-zone 5000 devices.
Sub-networks:
1
3
1 Sub-network 1
2 Sub-network 2
3 e. g. steel wall, wall, HGV, etc.
Sub-networks are created via an unintentional division
of the open network into two or more radio networks.
This can occur if the user is running two activated
Dräger X-zone 5000 (with the same network number).
This means that the devices have permanently
interconnected wireless connection (data transmission
LED is lit in green). This means that the user can no
longer tell whether or not the wireless connection is
already set up with the devices already installed. To
avoid sub-networks, the Dräger X-zone 5000 devices
should always be set up and switched on in succession.
