Installing MapIT G2 Control Bus Cables
The Control Bus Cables provide connectivity to the MCP, DCPs, SPPs and SFEs
installed in the system. The installation of the cabling should follow the installation
practices found in the Siemon Cabling System Training Manual.
Control Bus Cable Construction:
•
Category 5e, 24 AWG, shielded, solid. Use Siemon Premium 5e F/UTP. Use of
UTP or stranded shielded cable is not permitted. All terminations (S110, S310
and RJ45) should be done using the T568A wiring scheme
•
If double-ended shielded Patch Cable cables are used they must be constructed
with Siemon Premium 5e F/UTP 24 AWG, shielded, solid cable and PS-8-8
plugs. Cables must be wired using T586A wiring scheme. Stranded cable is
not acceptable.
•
If single-ended Patch Cable cables are used, they must be wired T568A and
use Siemon Premium Category 5e, 24 AWG, shielded, solid cable
Rule for Termination of Control Bus Cable in a Small Patch Zone with a Single
MCP:
If using the S310 and S110 blocks to terminate control bus cables…
•
Only use the S310 on the rear of the MCP. Do not use the RJ45s on the front of
the MCP. Use optional RJ45 port blockers (LL-05) to prevent use of RJ45s.
•
Terminate cable to S310 blocks on the MCP using T568A wiring scheme.
Connect the drain wires to the ground termination points. Maximum length of
each ca
ble is 50’ when connected to the first SPP/SFE as a daisy chain
•
Terminate the Control Bus Cable coming from the MCP to the “IN” S110 block
on the first SPP in the daisy chain. Use T568A wiring scheme. Connect the
drain wire to the ground termination point on the rear of the SPP
•
Terminate the SPP Daisy Chain cable to the OUT S110 block of the first SPP to
the IN S110 port on the next SPP/SFE in the daisy chain. Repeat for up to 5
