18. Fault List
Panel Faults Description In Log Symptom
MN Mains Input Failed. Check 230 volt supply and the fuse.
BT Battery Charging Fail. Check the battery connection and the fuse.
AT Main Receiver, Aerial
Tamper.
Occurs when one of the aerials have been removed.
Check 4k7 resistance that monitors the connections on
the aerials.
RI Radio Interference Check the radio interference threshold. If level seen is
higher than threshold, then there is excessive
interference in the air and the cause will have to be
identified.
OL Node Offline Occurs when one of the networked panels fails to
communicate between the master and vice versa. Check
the Lan module is on online also check connections, try
re-on lining the node from slave and master.
CK Checksum Changed Check the checksum is set to logged in the panel
hardware menu, reset the checksum data in the main
menu.
PR Processor Reset Silence and reset fault with the control key switch in the
“ON” position. (This happens when the panel is
restarted).
T/X UHF Txer Failed
Health Check
Occurs when the radio board is not communicating to
the charger relay board. Check the ribbon Cables on
radio pcb. Check the pager port is not redirected.
Tamper In To Tamper Check the device or unit to ensure it has not been
tampered with. Check the tamper switches are closed
and making good contact.
H/W Bus
node offline
H/W Bus Node Offline Occurs when hardwired units lose communication with
the panel, Check the RS485 bus connections on panel
and module. Try restarting the RS 485 bus.
Fire Into Fire A device has activated.
Test Alarm Into Test Alarm This occurs when a device has been activated whilst the
device/zone has been placed into test.
Fault Head Missing Occurs when a device head has been removed.
Fault A Supply Management Occurs when a fault is found on the batteries on a
device. (Low voltage).
Fault B Supply Management Occurs when a fault is found on the batteries on a
device. (Low voltage).
Fault C Supply Management This occurs when a fault is found on the batteries on a
device. (Battery missing).
Fault Intermittent Device Signal Occurs when the device has not called in within the call
in time period. Double basing the unit or moving the
VHF high gain aerial to a better position may aid signal.
Fault New Head Occurs when a new Sensor head has been inserted on
the base or the sensitivity settings have been change.
Fault
No ACK Received Occurs when an acknowledgement signal has not been
received from a device after a command has been sent
from the panel to a device. Take the device to the panel
and try sending another command to test the
transmitter and the receiver.
Fault
Radio Lan Node: 2 (Off-
Line)
Occurs when one of the networked panels fails to
communicate the master and viseversa. Check the Lan
module is on online, try re-on lining the node from slave
and master.
Fault Open Circuit Occurs when a monitored circuit has been opened.
Fault Short Circuit Occurs when a monitored circuit is shorted.
Fault Condition Ready Occurs when a monitored circuit is back in normal state.
Fault Sounder Test Fail Occurs when either an individual sounder test command
is sent to a device and the unit fails to sound or if
displayed for device 256 (see section 17).
