7.0 Telephone Connections
7.1 Registration
The Bosch Security Systems, Inc. D9412GV4,
D7412GV4 and D7212GV4 Control Panels are
registered with the Federal Communication
Commission (FCC) under Part 68, for connection
to the public telephone system using an RJ31X or
RJ38X jack installed by the local telephone
company.
An RJ31X jack can be modified by
placing a jumper wire between
Terminals 2 and 7 to become an RJ38X
jack.
7.2 Notification
Do not connect registered equipment to party
lines or coin-operated telephones. Notify the
local telephone company and provide the
following information before connecting the
control panel to the telephone network:
 The particular line to which the control panel
will be connected
 Make (Bosch Security Systems, Inc.), model
(D9412GV4, D7412GV4 or D7212GV4), and
serial number of the control panel
 FCC registration number:
US:ESVOT00BD9412GV4
 Ringer equivalence for the control panel: 0.0B
7.3 Location
To prevent jamming of signals, wire the RJ31X or
RJ38X jack before the in-house telephone system
to support line seizure (Figure 9). Install the jack
on the street side of the telephone switch, wired
ahead of any PBX equipment. Line seizure
temporarily interrupts normal telephone usage
while the control panel sends data. After
installation, confirm that the control panel seizes
the line, acquires dial tone, reports correctly to
the receiver, and releases the telephone line to
the in-house telephone system.
