Is the control panel compatible with digital or VOIP phone lines?
The control panel has been tested with only analog lines. Use a B420 Ethernet Communication
Module or a DX4020 to transmit over Ethernet or a ITS-DX4020-G to transmit over cellular.
You can use a C900V2 to convert analog signals to Ethernet for transmission to a D6600/
D6100i receiver.

How do I clear alarm memory?
Ensure all points are normal, and the enter your passcode and press [ESC], or press the
[Clear] soft key.
How do I determine if I have a ground fault?
On the control panel, measure voltage on terminal 9 (common) and terminal 10 (earth
ground). Approximately 6.5 to 6.8 VDC is normal voltage and equals no ground fault.
Disconnect wires until you see normal voltage to find your ground.
Can I add wireless capability to this control panel?
Yes. By adding the B820 SDI2 Interface Module, you are able to connect to an Inovonics
EN4200 EchoStream Serial Receiver via the SDI2 bus. By doing so, this allows you to connect
to any Inovonics EchoStream wireless peripheral.
What type of cable do I use to connect my computer’s COM port to a serial-enhanced direct
connection using the DX4010V2?

How can I determine which points are not ready when my keypad reads "NOT READY TO
ARM"?
Press the NEXT key to scroll through faulted points. If the VIEW POINT STATUS menu item is
enabled, you can access it through the menu to determine the state of the faulted point.
What does it mean when my keypad reads "CHECK DEVICE"?
A point is faulted. The point is one that is configured to display as a device in the POINT INDEX
by marking YES for the DISPLAY AS DEVICE parameter.
I hear a trouble tone from my keypad but no point is shown as in trouble on the keypad.
How do I resolve this?
A point generates a trouble tone (buzz) when faulted if is configured to do so. To determine
which points are configured to buzz, look in the POINT INDEX for points with a non-zero value
for the BUZZ ON FAULT parameter.

log by date and time.
