COMBUS Low Pwr
-
Modules are not getting enough voltage from the
COMBUS. Check for proper connection of COMBUS, or the COMBUS needs
to be repowered. See 4204 modules and the 4204 PGM COMBUS power
option for supplying voltage to the COMBUS. See “Diagnostics” in the
Programming Manual to determine which module has low voltage.
Internal Fault
-
A problem has occurred with the COMBUS microprocessors. If
this trouble occurs, check connections to the COMBUS and do a system reset.
4204 Battery TBL
-
If any PC4204 relay output module’s battery drops
below 11.3 volts, a battery trouble is generated.
To determine which of the PC4204’s has the low battery, check the reporting
code transmitted to the monitoring station or check the event buffer printout
if there is a printer attached, or through downloading. The battery voltage is
checked once every 4 minutes. So the battery trouble may not restore
instantly when the battery voltage is restored.
4204 AC Trouble
-
If any PC4204 relay output module loses incoming AC power,
the keypad trouble light will indicate a 4204 AC trouble. But there will be no
audible annunciation until there is also a low battery condition.
The PC4204 AC troubles will be transmitted to the monitoring station immediately.
4204 AUX Trouble
-
If the Aux fuse on any PC4204 relay module should
open or if the Aux supply is overloaded, a 4204 Aux trouble is generated.
Ground Fault - A Ground Fault trouble condition will occur if the Earth Ground
(EGND) connection is shorted to a positive voltage source or shorted to a
non-earth ground potential. This trouble will generate an audible and visual
trouble as well as a Ground Fault reporting code transmission.
Waterflow TBL - If the Waterflow zone on a PC4700 Fire Module is opened
(WFA or WFB), a visual keypad trouble (trouble LED will come on) with
audible indication and a Waterflow trouble transmission is generated. The
LCD will show the message "FIRE TROUBLE!! Waterflow TBL", until the
Waterflow zone trouble is restored. If there is more than one PC4700 trouble
condition present these trouble messages will scroll every 3 seconds to the
next message.
Cellular Trouble -
This indicates that the LINKS unit has one or more of the
following trouble conditions: AC, battery, loss of cellular or a tamper fault.
DLS Fault TBL - This trouble condition will generate an audible and visual
trouble when the control panel fails to complete communications with the
downloading computer.
Zn Sensor Fault - This trouble condition will occur when a wireless zone
fails to report a zone supervisory. To view which zone has the trouble press
the [✱] key while viewing the trouble condition. The zone(s) with the trouble
condition will be displayed in numerical order on the display. A keypad
trouble is generated when the system is disarmed and a visual "Zn Sensor
Fault" trouble and trouble reporting code will be transmitted.
