SYSTEM FAULT RECALL FAULT LIST (CONTINUED)
17. System/Auto Test circuit test fail
A circuit test failed during system or Auto Test or an unexpected fault or alarm
occurred during the test. The Brigade fault relay is turned on when this fault is
present. The fault will be cleared by a successful system or Auto Test. Isolating
the faulty circuit & performing a system test should allow the test to pass & clear
the fault.
18. Shift register bus fault
This error indicates a fault with the bus connecting the Controller with the
MAF/PSU, zone modules and relay modules. It may be caused by a break or
short in the flat ribbon cable (e.g. bd unplugged), by temporary noise, or by a
circuit board fault.
When this fault occurs all processing of inputs stops until the fault clears. If the
fault does clear, processing of inputs resumes automatically.
19. RZDU x
This displays the current status of any RZDU which has an off-normal condition.
Refer to Section 6.13 for a description.
20. Net msg discard
This occurs only with network systems. The local system discarded a message
that was repeatedly sent to another device on the network that did not
acknowledge it. To allow other messages to be sent on the network, the
unacknowledged msg was discarded. This should occur only in cases of extreme
network loading, if the system addressed does not exist or is off line, or if network
cables are broken.
21. Net port hw fault
This indicates a hardware fault with the serial port interfacing to the network. Call
the service company.
22. Clock crystal timebase check fail
This error message occurs only at startup and indicates the frequency of the
clock chip on the Controller is out of tolerance to the microprocessor. The
Controller will restart and try the test again.
23. Clock register write read fail
A test of the Controller time/date clock registers has failed. The Controller will
restart and try the test again.
24. Clock chip RAM write read fail
A test of the Controller’s clock RAM has failed. The Controller will re-start and try
the test again.
25. Shift reg clocking fault
This is the same fault as “Shift register bus fault” above. However, this fault
occurs only at startup or on exit from programming mode when the panel is trying
to determine what modules are present.
