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 58, "Edit Module Screen for Monitor Module" on page 68 and
"Edit Module Screen for Control Modules" on page 77 for information on additional
device types.
<ADJ>; refers to the user programmed adjective descriptor from library list resident in the
control panel or custom entry via PC.

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
