Remedy

The receiver answers the call and provides an initial “handshake” acknowledgment, but does not acknowledge the D9112's report transmission with a “kiss-off” acknowledgment .

The receiver is not compatible with the D9112's transmission format.

Noisy phone lines are interfering with report transmission.

Verify that the receiver is compatible with the format the D9112 is using (either BFSK or Modem II). SeePhone in the D9112 Program Entry Guide (74-06145-000).

Modem II requires D6500 MPU and Line Card EPROM revision 6.00 or higher.

Try making a voice call to the receiver on the line to verify the noisy condition. It may be necessary to have the phone company check the lines.

AC induction through the on-board point sensor loops, the DATA BUS, or the

ZONEX BUS.

1.Verify that the data/power cord is plugged into the COMMUNICATOR port on the D5200.

2.Verify that the data/power cord is plugged securely into the D5200 programmer.

3.Check each conductor in the data/power cord for continuity.

1.Verify a proper earth ground at terminal 10.

2Disconnect on-board point sensor loops, the DATA BUS (terminals 30, 31), and the ZONEX BUS (terminals 25, 26,27,28).

After plugging in the programmer, the panel transmits SDI trouble reports for supervised SDI devices (command centers, printer interface modules, etc.). All SDI devices stop operating.

You haven’t entered the D9112 handler within 30 seconds of plugging in the programmer.

Enter the D9112 handler within 30 seconds of plugging in the programmer.

Once the SDI reports are generated, entering the handler or disconnecting the programmer returns the SDI devices to normal operation.
