10.1 SYSTEM TESTING & FAULT FINDING
The F3200 has various test and diagnostic facilities to check functionality of the system
and assist fault finding.
Self Testing includes checking: Controller memory; real time clock; I/O bus
communications; modules present; and LCD module operation.
Should the Controller discover a fault it will annunciate a System Fault and take
appropriate action. For example, for a module failure such that the Controller can no
longer clock data to/from it, the Controller will display "Shift Register Clocking Fault", turn
on the System Fault LED, de-energise the Standby relay and stop processing AZC
status.
Auto Test operates on a daily basis (holidays excluded) and includes Fault testing and
Alarm testing (programmable) of all AZC's.
Operator controlled tests include AZC (zone) Fault and Alarm tests, battery test, and
output tests (e.g. Test Relay).
The supervision facility on AZC's, bells and relay wiring allows detection of field wiring
faults.
Routine testing should include checking the operation of the FIP and various outputs.
The cause of any faults within the system can be found as per chapter 4.4.
Should a fault occur within the FIP electronics or system wiring, the operator should call
a service person to check functionality and establish which facilities do not operate.
Only a suitably trained technician should attempt to repair wiring or replace suspect
modules.
Test points on the pcb modules allow checking of DC voltages and various signals.
Once it is established which particular module has a fault, the FIP should be de-powered
(mains and battery) and the module replaced. (Refer to Chapter 10.2).
Faulty electronic modules should be returned to the factory for repair and testing. It is
not recommended that service staff repair electronic failures on site.
All faults and alarms should be recorded in the system log book, with time and date of
occurrence.
