ring the remote phone first and then switch to the local phone (see Software
Programming, page 6).
For this configuration, a standard touch-tone telephone is connected to the
Local Phone port on the EC-8. If desired, two touch-tone telephones can be
connected in parallel to the Local Phone port by using a telephone-type “Y”
adapter. Then connect an outside phone line to the TELCO IN port on the
consolidator. (Note: See Technical Requirements, page 3, for phone line
requirements. DO NOT plug a phone company phone line or PBX extension
line into the LOCAL PHONE port as damage will result.)
F. Sharing a Phone Line
Another telephone instrument (e.g. fax , modem, standard telephone, etc.) can
share the outside phone line with the EC-8 by connecting the outside phone
line to the “TELCO IN” port on the EC-8 and connecting the telephone
instrument sharing the line to the “TELCO OUT” port. Be sure to set the EC-8
not to answer before your other device picks up (or, if sharing with a standard
telephone, be sure to allow enough rings for the person answering the phone to
pick up). Note: The other device sharing the line should not be emergency
equipment of any kind.
G. Mounting the EC-8
The consolidator can be mounted on the wall using the tabs with keyslots on
each side, or it can lie on a flat surface.
H. Connecting Auxiliary Devices
Extending from the top of the unit is a white connector with three wires:
purple, red and yellow. These wires provide two dry contact closures to enable
activation of a relay for turning on accessory devices indicating that a call is
coming in to the Consolidator, as well as the ability to separately activate a
relay when the call is answered, such as a flasher/siren or a recording device.
(Contact Talk-A-Phone Technical Support for additional assistance in
connecting relays.)
When an Emergency Phone call is received at the Consolidator, a connection
will occur between the red and violet wires (normally open). When the call is
answered at the Consolidator, the red and yellow wires (normally closed) are
also connected. In this way, one or more devices can be activated through
appropriate relays when the Consolidator is receiving calls, and one or more of
them can be turned off when the call is answered. All three lines go “open”
when the Consolidator has completed all activity (all calls answered).
