If the control panel indicates a trouble, you can do the following:
1. Press the ACKNOWLEDGE/SCROLL DISPLAY key to silence the panel sounder and switch the
SYSTEM TROUBLE LED from flashing to steady—regardless of the number of troubles, alarms,
security and supervisory signals.
2. The control panel sends an Acknowledge message to the History buffer and installed printers,
FDU-80 annunciators, and CRT-2s.
Figure 3.7 Sample Acknowledge Message
3. Check the trouble message for the location and type of trouble.
Figure 3.8 Sample Trouble Messages on CRT-2 or Printer
4. Correct the condition causing the trouble. If the trouble clears, the control panel sends a Clear
Trouble message to the History buffer and installed printers, FDU-80 annunciators, and
CRT-2s.
If all troubles clear and no supervisory signals or fire alarms exist, the control panel does the
following:
• Returns to Normal operation (indicated by the “System Normal” message)
• Sends a “System Normal” message to the LCD display, History buffer and installed printers,
FDU-80 annunciators, and CRT-2s
• Restores troubles automatically - even if troubles are not acknowledged
If multiple trouble conditions exist in the system, the LCD and optional CRT-2 and FDU-80
annunciators display automatically step through each trouble every 3 seconds in the following
order:
1. Alarms, in order of address
2. Supervisory, in order of address
3. Troubles, in order of address
