Manual Extinguishant Release Faults
Indications
•
Call Point LED on the Extinguishing Control Unit illuminates.
•
Fault LED on the Extinguishing Control Unit illuminates.
•
Fault message is displayed on the ZP3/ZP5 Control Panel and the panel buzzer sounds. The
Fault LED on the Control Panel also illuminates.
GNFLT
Zone 001 Dev 5001 Event 002
Probable Cause
SWT3-1 or link L3 on the Extinguishing Control or Status Units display PCB respectively is not
correctly setup or the monitored circuit has gone open-circuit.
Corrective Actions
1.
Press the ACCEPT button to accept the fault.
2.
Check the number of Extinguishing Status Units on the system.
3.
Make sure that SWT3-1 is OFF on the Extinguishing Control Unit and that L3 is removed from
the Extinguishing Status Units.
4.
Insert Link L3 in its appropriate position on the last Extinguishing Status Unit only. This causes
the EOL resistor to engage.
5.
If there are no Extinguishing Status Units on line then switch SWT3-1 ON, on the Extinguishing
Control Units display PCB.
6.
Check the continuity of the monitored circuit.
7.
Reset the panel.
Extinguishant Actuator Faults
Indications
•
Detonator Fault LED on the Extinguishing Control Unit illuminates.
•
Fault LED on the Extinguishing Control Unit illuminates.
•
Fault message is displayed on the ZP3/ZP5 Control Panel and the panel buzzer sounds. The
Fault LED on the Control Panel also illuminates.
GNFLT
Zone 001 Dev 5001 Event 002
Probable Cause
•
EOL resistor across the actuator switch is not inserted or the circuit is an open circuit. See
Figure 5 in ZP3-ECU Extinguishing Control Unit Installation and Maintenance Manual,
document number 503-0800ZE-I-01 if required.
•
Detonator Fuse on the Extinguishing Control Unit PCB is missing or blown.
Corrective Actions
1.
Press the ACCEPT button to accept the fault.
2.
Inspect the EOL resistor. If missing, insert one between terminals 7 & 8 of TB3 on the ECU
display board.
3.
Inspect Detonator fuse, replace fuse if it is missing or blown.
4.
Check continuity of the monitored circuit.
5.
Reset the panel.
