Typical Telco Overview With The Unit - Chamberlain EL1SS Installation And Programming Manual

INTRODUCTION

TYPICAL TELCO OVERVIEW WITH THE UNIT

CONNECTING THE BYPASS BOARD
The bypass board allows the EL1SS unit to be disconnected
without interrupting normal telephone operation. If the unit is
used in conjunction with an alarm system, you must connect
the telephone line to the alarm system fi rst or the unit will not
operate properly.
NOTES:
• When a unit is in use, the bypass switch must be set to
operate.
• When a unit is disconnected, the bypass switch must be
set to bypass.
• If the unit will be connected with an alarm system, you
must connect the telephone line to the alarm system
first in the series from the Telco box. If the units are not
connected in this order, they will not operate properly.
Phone lines with DSL service. In order for the EL1SS to function normally a DSL filter is required to separate the DSL (digital) signal
from the telephone service (POTS).
1. Install the splitter between the demarcation box and the EL1SS.
2. Route the DSL/Phone wires from the demarcation box to the splitter's input terminal.
3. Run a copper, twisted pair from the splitter's phone output to the EL1SS.
4. Run the data wires from the splitter to the resident's computer network.
