Cabling
General cabling guidelines:
• A single common ground is required for all
system components.
• All wiring that runs through a plenum area
must be plenum rated.
• RF controller cabling should not share conduit
with mains line power cabling.
• All exposed wiring must be concealed with
raceway or similar cabling protection.
• apC/iStar RS-485 cable runs of exceptional
distance may require Belden 9842, which IS
NOT plenum rated.
• Synchronization cabling is required for RF
controllers located within 152m (500ft) of each
other, even when they are not connected to the
same system.
• Passage antenna wire loop may be exposed to
corrosive cleaning fluids; cable jacket MUST
be composed of a fluoropolymer such as FEP
Teflon or Kynar with a thickness of .3mm
(.015in.).
