Plan to replace the lithium battery after 3 to 5 years of
continual service.
When replacing the lithium battery,
ensure that you disconnect the primary
AC power and secondary battery power
from the control panel before you remove
the old battery. Then install the new
battery and connect the primary AC and
secondary battery power to the control
panel.
3.3.4 Telephone Line Sniff
The D9412GV2 and D7412GV2 control panels
monitor the phone line for the programmed
supervision interval before indicating a phone line
trouble. If trouble occurs, refer to the
D9412GV2/D7412GV2 Troubleshooting Guide (P/N:
F01U011024).
3.3.5 Points
The Bosch Security Systems, Inc. D9412GV2 Control
Panel provides up to 246 points of protection. The
D7412GV2 Control Panel provides up to 75 points of
protection. Point programming parameters determine
the control panel’s response to open and shorted
conditions on the sensor loop for the point. Several
options allow individual point programming to custom-
fit the protection to the installation.
Points 1 to 8 are located on the circuit board (on-
board points). They are standard sensor loops. The
remaining off-board points are POPIT points using
D8128D OctoPOPITs, D8125 POPEX Modules and
D9127 or D8127 POPITs. MUX devices can also be
used with D8125MUX or wireless transmitters with the
ISW-D8125CW and D8125INV.
3.3.6 Areas and Accounts
The system supports up to eight separate areas. You
can assign all points to a single area or distribute
them over as many as eight areas.
The control panel is armed and disarmed by area,
and several areas can be armed and disarmed with
one menu function. A passcode can also be assigned
an authority level that allows a user to arm an area
from a remote keypad in another area. Assigning
each area its own account number creates eight
separate accounts in one control panel. Assigning the
same account number to different areas groups them
together in a single account.
Area options include exit tone and delay, separate fire
and burglary outputs, and multiple opening and
closing windows. Area type can be used to create
area interdependencies for arming purposes.
3.3.7 Digital Communicator
The control panel uses a built-in digital communicator
to send reports to the receiver. The control panel
sends reports in either the Modem IIIa
2
or binary
frequency shift keying (BFSK) format. The
microprocessor unit (MPU) and line cards for the
D6500 receiver must have the correct software
revision installed to accept Modem IIIa
2
reports from
the control panel. Refer to Table 4. All software
versions for the D6600 can be used with the control
panel.
