Trouble Operation | Operating Instructions |
For addressable devices connected to the SLC loop, the following is a typical message that could appear on the LCD display for a device trouble:
TROUBL SMOKE (PHOTO)<ADJ> <NOUN>INVREP 10:00A 010801 1D001The 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 49, "Edit Module Screen for Monitor Module" on page 59 and "Edit Module Screen for Control Modules" on page 68 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 01 for the year 2001
Device Address; 1D001 in this example 1 represents SLC Loop, D represents a detector and 001 represents device address 001
