The KMC KMD-5575 Network Repeater-Isolator extends and reconditions
EIA-485 network communications as well as enabling “T” or branch networks.
The KMD-5575 is designed to recondition a degraded EIA-485 (formerly RS-485)
communication signal on a KMC KMDigital or BACnet subnetwork. Two primary
factors that cause communication signal degradation within the digital subnetwork are long subnetwork wiring lengths and the number of digital controllers
connected to the subnetwork.
A KMD-5575 is required aer every 31 consecutive controllers on KMDigital or
BACnet subnetworks (e.g., between controllers 31 and 32) or if the cumulative
wiring distance exceeds 4,000 feet. (For smoke control applications, the maximum
total length of the EIA-485 network cable, including all repeaters, is 4,000 feet.)
In addition, the KMD-5575 is required for “T” or branch network wiring congurations (see Illustration 4 ).
Illustration 1 shows the major module components and their connections.
Installation
Mounting
Fasten the KMC KMD-5575 securely to a at surface inside a metal enclosure
using #6 hardware in the four mounting holes on the top and boom (see Illustra-
KMD-5575 3 Installation and Operation Guide
tion 2). For HVAC applications, KMC Controls recommends using a UL Listed
enclosed energy management equipment panel such as a KMC model HCO-1034,
HCO-1035, or HCO-1036. The HCO-1102 enclosure will hold one KMD-5575.
For smoke control applications, the controller must be mounted in a UL Listed
Fireghter’s Smoke Control Station enclosure or listed enclosure with minimum
dimensions. The minimum enclosure size is 16 x 18 x 6 inches. KMC enclosures
HCO-1034, HCO-1035, and HCO-1036 are approved for this application. See
Smoke Control Manuals 000-035-08 (BACnet) and/or 000-035-09 (KMDigital).
To maintain RF emission specications, use either shielded connecting cables or
enclose all cables in conduit.
