Telephone Connections
Registration
The Radionics D9412, D9112, D7412, and
D7212 Control/Communicator panels are
registered with the Federal Communication
Commission under part 68, for connection to the
public telephone system using an RJ31X or
RJ38X jack installed by your local phone
company.
Notification
Do not connect registered equipment to party
lines or coin-operated telephones. You must
notify the local telephone company and supply
them with the following information before
connecting the panel to the telephone network.
•
The particular line you are going to connect
the panel to
•
Make (Radionics), model (D9412, D9112,
D7412, or D7212), and serial number of the
panel
•
FCC registration number and ringer
equivalence for the panel:
FCC Registration Number: AJ9USA-
18808-AL-E
Ringer Equivalence: 0.1A 0.2B
Location
To prevent jamming of signals, wire the RJ31X
jack before the in-house phone system to support
line seizure. See Figure 7. Install the jack on the
street side of the phone switch, wired ahead of
any PBX equipment. Line seizure provides for a
temporary interruption of normal phone usage
while the communicator transmits data. After
installation, confirm that the panel seizes the line,
acquires dial tone, reports correctly to the
receiver, and releases the phone line to the in-
house phone system.
Phone Cord Connection
Connect one end of a D161 (8') or D162 (2')
Telephone Cord to the TELCO Cord connector,
J3, located on the bottom left corner of the panel.
See Figure 8. Connect the other end to the
RJ31X jack.
Phone LED (Red)
The red Phone LED lights when the panel seizes
the phone line and remains lit until the panel
returns the phone line. See Figure 8 for the
location of the red LED.
Operation Monitor LED (Green)
The green LED indicates the operation of the
CPU (Central Processing Unit). When the CPU is
operating normally, the LED flashes 0.5 second
on, 0.5 second off.
The green LED also serves as a ring indicator.
See Figure 8 for the location of the LED. When
there is ring voltage on the phone line (the phone
is ringing), the green LED flickers at a faster rate
for the duration of each ring. Ring voltage must
reach a minimum of 45 VAC before the system
detects it.
Dialing Format
You can program the system to use DTMF or
pulse dialing. See
Phone Parameters in the
D9000/D7000 Series Program Entry Guide (74-
07695-000).
Phone Line Monitor
The panel has a built-in phone line monitor that
tests the phone line for voltage and current. If you
use the D928 Dual Phone Line Switcher to
connect 2 phone lines to the panel, the panel
monitors both lines. The normal voltage on a
telephone line is approximately 48 VDC (24 VDC
for some phone systems). The phone line monitor
senses trouble when the voltage on the line falls
below 4.5 to 7.5 VDC, without a corresponding
current increase to 8 to 13 mA.
If the monitor senses trouble, it starts a
programmable phone line trouble timer. The
timer continues to run as long as the monitor
senses trouble. It resets to zero when the panel
senses a normal line. If the timer reaches the
delay time in the
Phone Supervision program
item, it begins a phone line trouble response.
Programming determines what the response is.
See
Phone Parameters in the D9000/D7000
Series Program Entry Guide (74-07695-000).
