Johnson Controls ZFR1810 User Manual

ZFR1800 Series Wireless Field Bus System Technical Bulletin72
• Although the compatibility of WiFi and ZigBee products is based on standards
and good design, other sources can interfere with both WiFi and the wireless
system by overloading the bands with continuous transmissions at very high
levels. Many consumer 2.4 GHz wireless products, such as cordless phones
and some older phone headsets, can cause wireless interference and should not
be used anywhere near a wireless system or other WiFi applications.
Additionally, some camera and sound systems are continuous frequency
modulation transmitters, and they must be kept out of the WiFi environment to
ensure optimal operation.
• The wireless Metasys systems automatically choose the best channel of
operation at initialization. This channel can be overridden with a manual
command.
Wireless Security
The ZFR1800 Series Wireless Field Bus System is secure for the following
reasons:
• ZFR1800 Series Wireless Field Bus System devices transmit at a low
transmission power of 10 mW preventing outside sources from accessing the
system. You must be physically within the building to access and transmit on
the system.
• The ZFR1800 Series Wireless Field Bus devices transmit data using several
short messages that are collected and reconstructed at the destination. If a piece
of the message is intercepted, it is indecipherable to the outside source.
