Trouble Operation
The information displayed in the above example provides the following information:
•
First line in display:
• The type of event; in this example TROUBL indicating a device trouble
• Device type identifier; in this example, SMOKE (PHOTO) indicates a Photoelectric smoke
detector. Other device type identifiers which can be displayed include SMOKE (ION) for
Ionization Detector, HEAT for Heat Detector, CONTROL for Control Module and
MONITOR for Monitor Module, PULL STATION for a manual pull box, etc. Refer to "Edit
Detector" on page 46, "Edit Module Screen for Monitor Module" on page 56 and "Edit
Module Screen for Control Modules" on page 65 for information on additional device types.
•
Second line in display:
• <ADJ>; refers to the user programmed adjective descriptor from library list resident in the
control panel or custom entry via PC.
• <NOUN>; refers to the user programmed noun descriptor from library list resident in the
control panel or custom entry via PC.
•
Third line in display: INVREP indicates an invalid reply from the addressable device. Other
possible troubles include:
• SHORT - indicating a shorted circuit on an addressable device
• OPEN - indicating an open circuit on an addressable device
• DIRTY1 - maintenance alert indicating that a detector is near but below the allowed alarm
limit and is in need of maintenance before the performance is compromised
• DIRTY2 - maintenance alert indicating that a detector needs immediate maintenance since it
has been within 80% of its alarm threshold for 24 hours
• INVREP - maintenance alert indicating a hardware problem in the detector
• TEST F - indicating a detector has failed the automatic test operation which functionally
checks its sensing chamber and electronics
• INV ID - indicating that an incorrect device code (Type ID) has been programmed for an
installed device (for example, Photo has been programmed but an Ion detector has been
installed)
• SW TBL - indicating a module has failed the testing of its Class A switching relay
•
Fourth line in display:
• Time; the current time in this example is 10:00A which represents 10:00 AM
• Date; the current month, day and year in this example is 01 for January, 08 for the 8th day of
the month and 06 for the year 2006
• Device Address; 1D001 in this example 1 represents SLC Loop, D represents a detector and
001 represents device address 001
Pressing the Acknowledge/Step or Alarm Silence key will cause the pulsing piezo to silence and the
system Trouble LED to change from flashing to on steady. This block acknowledgment occurs
regardless of the number of troubles, alarms and supervisory events active in the system. When the
Acknowledge/Step key is pressed and at least one new alarm or trouble exists in the system, the
'acknowledge' message is sent to the printer and history file. If the trouble clears, either before or
after the Acknowledge/Step key is pressed, the 'clear trouble' message is sent to the printer and
history file.
If all troubles clear and there are no supervisory or fire conditions active in the system, the system
returns to normal mode operation and the System All Normal message is shown on the LCD display
and sent to the history and printer files. The auto-restore feature will restore cleared troubles even
if the troubles were never acknowledged. Note that pressing the Alarm Silence key when only
troubles exist in the system will have the same effect as pressing the Acknowledge/Step key except
the Alarm Silenced LED will light.
