Fault display & fault-finding
The Premier EX8 zone panels monitor for the following faults:-
•
Low or failed mains (Including fuses)
•
Low or failed battery (Including fuse)
•
Detection Zone open or short circuit wiring fault
•
Detection Zone detector removed.
•
Sounder circuit open or short circuit wiring fault
•
Bottle open or short circuit wiring fault
•
Monitored input circuit open or short circuit wiring fault
•
Earth Fault
•
System fault
•

•
Remote fault
Most of these faults will need to be checked by an engineer, but the system can be
checked for a removed detector by the responsible person.
All faults in the Premier EX8 are NON-LATCHING. IE they can not be reset with the
reset button. They will clear automatically when the fault has been fixed.
The exception is a SYSTEM FAULT, which means that the processor may have
crashed, and may or may not have restarted correctly.
Fault Finding
Power Supply faults (Battery Fault/Charger Fault/Low Battery)
A power supply fault is indicative of one or more of the following faults: -
Loss of Mains power
•
Check that 230V AC is present at the mains terminal block
•
Check mains fuse
•
Check that there is 30-34V coming from the transformer secondary
•
Check charger fuse FS9.
Loss of Battery power
•
Check that 2 X 12V batteries are fitted in series to give 24V backup
•
Check battery fuse FS8.
•
Check that battery connections are secure.
•
Check that the batteries are not over 5 years old
•
Check that the 2 batteries have a combined voltage of over 21V DC (The panel will refuse
to charge batteries with a voltage less than 21V because they can`t be guaranteed to hold
a charge)
The panel will also indicate a charger fault if the serial supply fuse (FS7) or parallel supply fuse (FS6)
have blown.
