Troubleshooting Guide

Introduction

Radionics provides this guide to help you troubleshoot problems with the 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 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 D9112 performs its self diagnostic tests at start up and
reset. The tests take approximately ten seconds. If all tests are competed 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 CMD 4 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 CMD 4 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.
