✔
DO
ensure that all instructions have been followed before
power is applied to system. The installation shall be carried
out in accordance with all applicable installation rules.
✔
DO
use only CAT5 & RG-6 and specified wires called out in
these instructions. The cable is designed and constructed
with electrical specifications necessary for proper audio
performance.
✔
DO
use only a damp cloth to clean the exterior plastics on
the VMC1 Master Station and Room Stations.
✔
DO
NOT use liquid or aerosols.
✔
DO
make gradual bends of the cable where necessary -- no
sharper than 1” radius.
✔
DO
dress the cables neatly with cable ties or Velcro™
wraps. Use loose or moderate pressure.
✔
DO
use cable-pulling lubricant only for cable runs that may
otherwise require great force to install. When cable lubricant
is used, read the instructions to be sure it is compatible with
the cable jacket material (PVC or FEP).
✔
DO
avoid stressing cable conductors, limit pulling tension to
25 pounds or less as specified by EIA/TIA-568A standard.
Pull cables gradually and with constant tension, taking care
not to crush or pinch bundles.
✔
DO
use grommets to protect the cable where passing
through metal studs or anything that can possibly damage
them.
✔
DO
test every installed cable run with a cable tester. “Toning”
alone is not acceptable.
✔
DO
label every termination point. Use a unique identifier
for each cable run. It will make moves, adds, changes, and
troubleshooting easier.
✔
DO
support horizontal cable bundles using board supports,
J-hooks, or cable trays.
✔
DO
have signal cables cross at right angles to power cables
to minimize induced interference.
✔
DO
always obey all local and national fire and building
codes. Be sure to “firestop” all cables that penetrate a
firewall. Use plenum-rated cable where mandated.
✔
DO
have a licensed electrician to run a 120 VAC line from
A DEDICATED 15-AMP BREAKER to the VMC1 power
supply.
✔
DO
Use CAT5 wire for all VMC1 wire runs.
✔
DO
label all wire runs. Connecting the wires to the VMC1
master, room station, or door station incorrectly may result
in system damage.
✔
DO
NOT STAPLE CABLES. Staples cause shorts.
✔
DO
NOT SPLICE CABLES. Splices are unreliable and
defeat the signal isolation properties of the cable.
✔
DO
keep cables at least 18 inches from fluorescent light
fixtures, Dimmer controls, and all other wiring. This includes
AC wiring, security cable, and other control wires. These can
cause a “hum” or “buzzing” sound.
✔
DO
keep cables away from objects such as heating and air
conditioning ducts, metal construction plates, and anything
else with sharp edges that can damage the cables.
✔
DO
follow the grounding and bonding requirements
established by Electrical Code TIA standard 607, and
equipment manufacturer’s specifications.
✔
DO NOT
locate the VMC1 Master Station or Room Stations
on an exterior wall.
✔
DO NOT
locate the VMC1 Master Station or Room Stations
in any wall cavity with any other electrical wiring in the cavity.
✔
DO NOT
attach non line-level audio devices or non M&S
authorized equipment to the system.
✔
DO NOT
power up Master Station until all speakers and
stations are connected.
✔
DO NOT
splice or repair cables damaged during wire
pulling, install a new cable.
✔
DO NOT
coil or bundle the cables. This can cause electronic
feedback.
✔
DO NOT
over-tighten the screws for the volume controls,
speakers, or the intercom Master Station to prevent
cracking.
✔
DO NOT
install any station or speaker cables inside the 120
VAC transformer enclosure.
✔
DO NOT
tie cables to electrical conduits or lay cables
on electrical fixtures. Keep cables at least 16” away from
fluorescent lights, HID light fixtures, or dimmers.
✔
DO NOT
allow the cable to be sharply bent or kinked at any
time.
✔
DO NOT
install cables “taut” anywhere. Good installation
should have cables loose, but never sagging.
✔
DO NOT
run signal and power cables parallel without
adequate separation to minimize interference.
✔
DO NOT
exert more than 25 pounds of tension on 4-pair
cables.
✔
DO NOT
step on CAT5 cable during installation.
✔
DO NOT
overtighten the cable ties, apply cable ties loosely,
with random spacing.
✔
DO NOT
untwist the wire pairs in CAT5 cable more than 1/2”
to avoid crosstalk.
