2.7 Telephone Line
The Model 1104 will operate with all standard telephone systems
that accept pulse or tone dialing. The Model 1104 cannot be used
on an extension line to dial its own telephone number. Also, it
may not be installed on a party line or pay telephone line.
Certain private telephone systems and public switching equipment
may not accept the Model 1104 dialing or may generate an
unacceptable ring signal. In those cases, a dedicated line may be
required. Consult the supplier of your telephone system if you
encounter problems.
If you do not have a modular telephone extension at the Model
1104’s location, you must contact your local telephone company
to have one installed (there is a charge for this service). If you
have four-pin jacks, adapters are available to convert them to the
modular plugs. Contact your local telephone company or
electronics parts store.
CAUTION
Never install telephone wiring during a lightning
storm. Never install telephone jacks in wet locations
unless the jack is specifically designed for wet loca-
tions. Never touch uninsulated telephone wires or ter-
minals unless the telephone line has been disconnect-
ed at the network interface. Use caution when
installing or modifying telephone lines.
To install the telephone line, plug the modular telephone jack
provided into any standard RJ11 phone outlet.
Refer to Figure 2-4.
Figure 2-4. Installing the Telephone Line
On the back of the Model 1104 is a female telephone jack. This
is provided so that a telephone or other answering device may be
used on the same line as the unit. It is not necessary to hook up a
telephone for the Model 1104 to operate.
