4. Installation Place and Mounting
It is strongly recommended to design the Natron wireless system in advance on paper, before
starting the installation. Natron WE-C expander (network gateway) module should be installed at
2-2.5m above the floor level.
Attention: Avoid installation of Natron WE-C module and the wireless devices near to:
• Power lines or other high voltage equipment with large electric consumption.
• Big metal structures – cabinets, pending ceilings, thick concrete walls. Note that, the quality
of the signal strength is reduced with 80%, and sometimes with 100% (full reflection) in
premises with metal walls or surfaces.
• Fluorescent lamps and lighting fixtures.
• Wi/Fi Routers, wireless telephone stations, computers and network cabling.
