FAULT LED illuminate. All other LEDs will 
be extinguished.

Warning: The system is completely inactive 
apart from the operation of Muster alarms 
if configured. 
User Actions:

decide whether special action (such as fire 
patrols) are needed in that area. 
•  Call your service engineer immediately. 
•  Record the event in the system log book.
