Connections 

7.1 Registration 

The Bosch Security Systems D9412GV2/D7412GV2 
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), model 
(D9412GV2 or D7412GV2), and serial number of 
the control panel 

•

 

FCC registration number: AJ9MUL-46532-AL-E 

•

 

Ringer equivalence for the control panel: 0.4B  

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 7). 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.
