3 Fault Codes
The following table lists the possible fault conditions reported on the Panel LCD and their meaning. The list is in
descending order of priority.
Item
Description
DEVICE MISSING
The pager interface is not responding to the panel communications.
Check power and serial communications connections to the interface.
Check that the Heartbeat LED on the interface is flashing.
CORRUPT DATA
The communications between the panel and the pager is being affected.
Check the serial communications connections to the interface.
PROGRAM FAIL
The pager interface has detected a checksum error in its operating
program.
Re-flash the operating program into the interface using the MxFlasher
Tool.
CONFIG. FAIL
The pager interface has detected a checksum error in its configuration
data.
Power down the interface then reapply power. Re-configure the interface
using the MxPager Tool with the configuration settings.
NOT READY
The pager interface has either never been configured or is not fully
configured.
This could occur if the RS-232 lead is disconnected during a
configuration upload.
Re-configure the interface using the MxPager Tool with the configuration
settings.
CPU RESET
The pager interface has just powered up or has been reset due to a
watchdog timer. This will not normally appear on the display but may
appear in the log.
DEVICE FAULT
The pager interface cannot establish communications with the ESPA
Paging system.
Check the serial communications connections between the interface and
the ESPA Pager system.
OPEN CIRCUIT
There is an open circuit condition on the Fault Input wiring.
Check the connections between the interface and the ESPA Pager
system including the EOL resistor.
SHORT CIRCUIT
There is a short circuit condition on the Fault Input wiring.
Check the connections between the interface and the ESPA Pager
system including the EOL resistor.
INPUT FAULT
The Fault Input is in its active condition indicating a fault condition from
the ESPA Pager system.
Check the ESPA Pager system.
NOTE: The input can be configured with an “Invert” property. Check that
the correct configuration has been used f
or this input’s required
operating properties.
Normal
The interface and the Fault Input are in their normal operating condition.
NOTE: Transmission to the Pager Interface is prevented whilst the panel is in COMMISSION mode. This is to
prevent the paging of unwanted / spurious messages whilst commissioning / testing the panel.
