Registration
The Radionics D9112 Control/Communicator panel is registered with the Federal
Communication Commission under part 68, for connection to the public telephone system
using an RJ31X jack installed by your local phone company.
FCC Registration Number: AJ9USA-18808-AL-E
Ringer Equivalence: 0.1A 0.2B
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 (D9112), and serial number of the panel
• FCC registration number and ringer equivalence for the panel (see
Registration
above)
Location
To prevent jamming of signals, wire the RJ31X jack before the in-house phone system to
support line seizure. See Figure 6. 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.
