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:

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
66, "Edit Module Screen for Monitor Module" on page 76 and "Edit Module
Screen for Control Modules" on page 85 for information on additional device
types.

Second line in display:

; refers to the user programmed adjective descriptor from library list

resident in the control panel or custom entry via PC.

; 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:

U SHORT - indicating a shorted circuit on an addressable device

U OPEN - indicating an open circuit on an addressable device

U 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

U DIRTY2 - maintenance alert indicating that a detector needs immediate

maintenance since it has been within 80% of its alarm threshold for 24
hours

U INVREP - maintenance alert indicating a hardware problem in the detector

U TEST F - indicating a detector has failed the automatic test operation which

functionally checks its sensing chamber and electronics

U 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)

U 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
