With no alarms, the detection of a trouble in the system will cause the panel sounder to sound, the
System Trouble LED to flash and the trouble relay to activate. A message will appear on the LCD
display indicating the trouble condition. The same message is sent to the printer and history file along
with time and date. A ground fault will also cause the yellow Ground Fault LED, located on the bottom
of the main circuit board, to turn on.

Addressable Smoke Detectors

For addressable Ionization or Photoelectric smoke detectors, the following is a typical message that
could appear on the LCD display for a detector in trouble.
The information displayed in the first line in the example above provides the following information:
• The type of event – in this example, TRBL indicates device trouble.
• The Specific Device Trouble for a Detector - the # symbol will be replace by a digit representing
a specific trouble condition (refer to the list of Specific Device Troubles listed below).
• Type of device – in this example, SMOKE DET indicates smoke detector.
• Point type and address – in this example, P01 indicates Photoelectric detector assigned to
address 01.
The information displayed in the second line in the example above provides the following information:
• <ADJ> – user programmed adjective descriptor from library list or custom entry (five characters
maximum).
• <NOUN> – user programmed noun descriptor from library list or custom entry (ten characters
maximum).
• Zone – zone to which the point is assigned.
The # symbol in the display will be replaced by a digit that represents the Specific Device Troubles as
listed below:
# Specific Device Troubles
1 Invalid Reply - may be due to:
1) incorrect pulse width received from a detector.
2) no answer from a detector due to either a complete device failure or removal from
the SLC loop.
3) an incorrect identification code received, i.e. a photo detector replaced by an ion
detector or vice-versa.
2 Maintenance Alert - indicates that a detector has been within 80% of its alarm
threshold for 24 hours, indicating that the detector needs cleaning.
3 Fail Automatic Test - indicates that a detector's sensing chamber and electronics
(which are tested for normal safe operation every two hours) has failed the test.
