RECOMMENDED SPEAKER CABLE
All speaker cables must be twisted-pair (unshielded or shielded) containing 18 or 22 gauge wire. If using a shielded cable
(ESCO# 408-0035), ground the shield at the inside end only. Use of twisted pair cable (ESCO# 408-0036) provides
easiest connection to each Sub-station speaker. All speaker cables must route through a conduit that is SEPARATE from
those containing 120VAC power wiring.
DO NOT UNDER ANY CIRCUMSTANCES ROUTE AUDIO CABLES IN THE SAME CONDUIT WITH 120VAC WIRING.
THIS VIOLATES THE NATIONAL ELECTRICAL CODE AND PRESENTS A HAZARD.
INSTALLATION OF THE TSC-1005C, TSC-1005CA OR TSC1005CM
A. Key points for greater sound quality.
1) Use recommended 18-22 gauge twisted pair wire.
2) Run cable separately away from high voltage power wiring.
3) Sub-station speakers mounted in close proximity of Master-station may result in a howl (acoustical feedback) when
either one calls the other. This condition can be corrected by lowering volume or repositioning Sub-station
speaker.
B. Speaker and Call switch mounting.
1) We recommend that you use ESCO Speakers and Call switches for optimum performance.
2) Mount Speakers and Call switches per the installation and application guide included.
C. Wiring
1) Run an appropriate length of ESCO# 408-0035 or 408-0036 speaker cable from each remote speaker and call
switch to the area where the intercom is to be located (tagging wire ends is recommended to avoid confusion when
final connection is made to intercom).
2) Strip 3/16" of insulation from the end of each wire and twist the strands together.
3) Connection of the remote speakers and call switches to the intercom should be as follows:
Speaker #1 connects to terminals marked Station #1.
Speaker #2 connects to terminals marked Station #2.
Speaker #3 connects to terminals marked Station #3.
Speaker #4 connects to terminals marked Station #4.
Speaker #5 connects to terminals marked Station #5.
All call switches connect to terminals marked Call.
4)
After completing installation, tie wires to bundle platform attached to intercom with a tie-wrap to insure no
movement of interconnect wiring.
5)
Power unit up and check operation of all connected speakers. If volume is to low or an acoustical feedback is
present, adjust outside speaker volume (located under intercom) accordingly.
6)
To insure proper warranty protection, be sure to fill out warranty registration information and return immediately.
