Before installing the system the following points
need to be considered.
The communication range between the translator,
expanders, and all wireless devices is specified in
‘free air’. The range will vary and generally decrease
when installed within building structures.
It is recommended that preliminary system design is
made on paper. Optimum device positioning can be
verified during installation and additional expanders
can be added if required.
The number of translators / expanders required is
determined by the number of wireless devices
connected to the control panel and the
communication range between the translators /
expanders and wireless devices.
EK‐WL8‐EXP expanders should be used when
some wireless devices are too far from the
translator
the translator’s communication range does not
cover the necessary territory (e.g. the whole
building or one of the floors)
connection with wireless devices is weakened by
external electromagnetic interference
the building has thick walls, metallic structures or
other objects that significantly lower the
communication range of the translator and
wireless devices
backup and alternative communication routes
need to be provided in the system
The system designer needs to evenly disperse
expanders across the premises in order to provide a
stable connection to the network in every part of the
building. Wireless devices will automatically choose
the closest expander that will provide the strongest
connection.
When designing a wireless fire alarm system, it is
important to keep in mind that the communication
range
between
different
wireless
devices
significantly depends on walls and obstacles that can
block radio communication. This is why it is
recommended to check the connection strength
between different rooms in the building before
designing and installing the system.
