Connect the 47 KΩ, ¼ W
EOL resistor or the diode
only on last sounder of
the line.
Polarity displayed are in
Alarm condition, at idle
condition, they are
inverted!
6.3.2 General Fault relay
The General Fault relay is usually in energized state. It is de-energized in
Fault condition. This output is available in free voltage.
Contact range: max 30 V AC / DC, 1 A, Non-inductive loads
Setting of the general fault output with N.O. contact (Jumper JGST).
