Zone Fault
A Zone Fault is indicative of one or more of the following faults:-
Open Circuit fault.
•
Check that the correct end of line DIODE (1N4002) has been fitted
•
Check that there are no breaks in the cable, and that all screw connections are
secure.
•
Check that no detectors have been removed from the circuit.
•
Check that all detectors are correctly fitted to their bases.
•
As a cable check, remove zone wire from panel. Temporarily join the + & - cables
at the end of line & Check for continuity. (If a break is found, splitting the line in
half & fitting EOL will help determine which section of cable has the fault)
•
As a panel check, remove cable & fit EOL at the panel. If the fault clears, the
panel is working correctly.
•
If a panel does not report a fault when an detector is removed, check with your
supplier if the detector is compatible with the Premier Elite.
Short Circuit Fault (Gen S/C LED will be lit)
•
Check that the correct end of line has been fitted (1N4002 DIODE), and check
that it has not been fitted backwards. It should be fitted stripe to +ve.
•
Check that no equipment, other than detectors or call points has been fitted to the
zone.
•
Check for shorts to the cable screen.
•
Check that none of the heads have become damaged (remove one at a time).
•
As a panel check, remove cable & fit EOL at the panel. If the fault clears, the
panel is working correctly.
Sounder Circuit Fault
A Sounder Fault is indicative of one or more of the following faults:-
Sounder Open Circuit fault.
•
Check that the correct end of line resistor (10K) has been fitted to both circuits
•
Check that sounder fuses FS4 & 5 are intact.
•
Check that there are no breaks in the cable, and that all screw connections are
secure.
•
As a panel check, remove both circuits cable & fit both EOLs at the panel. If the
fault clears, the panel is working correctly
.
Short Circuit Fault (Gen S/C LED will be lit)
•
Check that the correct end of line has been fitted to both circuits (10k resistor)
•
Check that ALL sounders, Bells etc are POLARISED, and are fitted the correct
way round. (see diagram after list)
•
Check for shorts to the cable screen.
•
As a panel check, remove cable & fit EOL at the panel. If the fault clears, the
panel is working correctly.
Note: If non-polarised
alarm devices (eg some
types of old mechanical
bell, or a relay) are
used, then a diode will
have to be placed in line
with the device to
enable fault monitoring.
They may also need a
back EMF protection diode. (symptoms: Chattering sounder relays that don’t turn off).
