12. Troubleshooting
12.1 Introduction
Use this guide to help troubleshoot problems with the
D9124 Control Panel. To prevent problems from
occurring, read the preceding sections and the D9412G /
D7412G Program Entry Guide to verify the control panel
is correctly installed and programmed.
12.2 Self-Diagnostic Tests
D9124 Control Panel performs a series of self-diagnostic
tests of hardware, software, and programming at start up
and reset.
12. Troubleshooting
Buzzer sounding is normal at start-up: The on-board
buzzer, located on the lower right corner of the control
panel, sounds as the D9124 performs self-diagnostic tests
at start up and reset. These tests take less than 2 seconds.
If all tests complete successfully, the buzzer turns off.
The control panel continues periodic internal testing
during normal operation. If a fault is detected during
testing, the buzzer sounds.
Table 16 identifies system problems that display during
self-diagnostic tests and describes how to troubleshoot
them.
