Troubleshooting Guide
Introduction
Radionics provides this guide to help you
troubleshoot problems with the D9412/D9112. To
prevent problems from occurring, read the
preceding sections of this manual and the
Program Entry Guide to verify that the panel is
correctly installed and programmed.
Self Diagnostics
The D9412/D9112 performs a series of self
diagnostic tests of its hardware, software, and
program at start up and reset.
Buzzer sounding is normal at start-up: The on-
board buzzer located on the lower right corner of
the panel sounds as the D9412/D9112 performs
its self diagnostic tests at start up and reset. The
tests take less than two seconds. If all tests are
completed successfully, the buzzer turns off.
The panel continues periodic internal testing
during normal operation. If a fault is detected
during this testing the buzzer begins sounding.
One of the system messages listed below
displays at the Command Centers.
CALL FOR SERVICE
- Trouble at Command
Center
When a Command Center stops receiving data
from the panel, CALL FOR SERVICE appears in
the Command Center's display. No buzzer
sounds at the Command Center.
PANEL BROKEN
- Hardware, Software Failed
If a hardware or software problem causes the
buzzer to sound, the green operation monitor
LED stops flickering or is off. PANEL BROKEN
appears in the displays of all Command Centers.
Pressing "ESC" does not silence the buzzer. You
must return the panel to Radionics for repair.
Attach a Radionics
Return Tag or call Customer
Service for a return authorization.
PARAM FAIL
- Program Parameters Failed
If a corrupted program causes the buzzer to
sound, the green operation monitor LED
continues to flicker. See
Operation Monitor LED
in the
Telephone Connections section for a
description of the green LED. PARAM FAIL
alternates with the idle text at the Command
Centers. The panel sends a PARAM FAIL report
to the receiver.
Pressing "ESC" may silence the buzzer.
Silencing the buzzer does not correct the
problem: You must replace the corrupted copy of
the program in the panel. Load a new copy of the
complete program.
The displays clears when you reset the panel
after loading a new program.
SERVC AC FAIL
- AC Power Failed
An interruption of AC Power at terminals 1 and 2
causes SERVC AC FAIL to appear in Command
Center displays. You can program the panel to
send an
AC FAILED
report to the receiver.
Pressing "ESC" silences the buzzer. Restoring
power clears the display.
SERVC BATT LOW
- Battery Voltage Low
If battery voltage at terminals 4 and 5 falls below
12.1 VDC, a SERVC BATT LOW appears in
Command Center displays. See
Battery and
Power Reports in this section for probable
causes and remedies.
Pressing "ESC" silences the buzzer. The display
clears when battery voltage reaches 13.7 VDC.
SERVC BATT MSING
- Battery Missing,
Shorted, or Reversed
If the panel can not detect a battery at terminals 4
and 5, a SERVC BATT MSING appears in
Command Center displays. You can program the
panel to send a
BATTERY MISSING
report to the
receiver.
Pressing "ESC" silences the buzzer. Restoring
the battery clears the display.
COMM FAIL ROUTE# 1
(or 2, 3, 4) - Route
Communications Failure
FAIL ROUTE # appears in Command Center
displays after the panel makes 10 unsuccessful
attempts to report to the receiver.
Pressing "ESC" silences the buzzer. The display
clears when communication restores (the
receiver acknowledges a report). See
Communication Failure in the Telephone
Connections section for a complete description.
