10 R-Series Remote Annunciators and Expanders Installation and Operation Guide
Troubleshooting
When an 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 18 for
details about message displays.
The following table summarizes symptoms and solutions for common installation
and operation problems.
