Troubleshooting
When a K-R Series annunciator is operating correctly, the Trouble LED follows the panel’s Trouble LED.
Annunciators with LCD displays show the same trouble messages as the panel. See the topic “Reading LCD
displays” on page 16 for details about message displays.
The following table summarizes symptoms and solutions for common installation and operation problems.
