Chapter 4 UCM Communication-Link Wiring
54 BMTW-SVN01F-EN
Communication-Link Wire
All Tracer Summit communication-link wiring is low voltage Class 2 and
must be field-supplied and installed in compliance with NEC and local
codes. To prevent electrical noise interference, all communication-link
wiring must also comply with the requirements outlined in this section
for wire selection and individual link configuration. Fiber-optic UCM
communication is also available where extreme distance, electrical noise
immunity, or building-to-building communication is required (See “Fiber-
Optic UCM Communication” on page 64).
Do not run communication-link wiring in the same conduit or wire bundle
with ac-power wires. This could cause the BCU to malfunction due to
electrical noise.
Typical UCM communication-link field wiring is illustrated in Figure 23
on page 55.
