Figure 4-18: RJ-11 to DB-9 Adaptor for TEL-14 Interfaces
Note: The TEL-14 interface works with telephone company central
office (CO) lines. Analog panel lines from some in-house
PABXs are not compatible.
Telephone Set
Although it is possible to use a parallel-connected telephone set to
originate calls, it is preferable to use a series-connected telephone set
with the TEL-14. This will prevent the impedance of the telephone set
from disturbing the telephone line impedance recognized by the
TEL-14. It will also allow the TEL-14 to automatically disconnect the
telephone when it comes “off-hook.” A standard telephone may be
installed in series with the TEL-14 by connecting it to pins 1 and 6 of
the RJ-11 jack. If telephones must be connected in parallel with the
telephone line(s) during the TEL-14’s automatic nulling process, all
additional standard telephones must be “on-hook”.
Relay Contacts
A pair of relay contacts for each telephone line rated at 2A at 24 VAC is
available on the DB-9 or the RJ-11 of the adapter. This pair of contacts
is normally open when the line is “on-hook,” and closes when the
interface goes “off-hook”. These contacts are not connected to any
other circuitry inside the interface, and can be used to energize a
line-in-use indicator light on a standard multiline phone set, or for any
other low-power application.
RLY-6 INTERFACE WIRING
The RLY-6 relay interface module provides connection of six
programmable relays to the matrix so that each relay is directly
controlled from the matrix. Multiple RLY-6 interfaces can be daisy
chained to provide connection of up to 60 relays to the matrix. RLY-6
