R Series Remote Annunciators and Expander 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 14 for details about message
displays.
The following table summarizes symptoms and solutions for
common installation and operation problems.
