The following wiring diagrams displays the process to connect notification devices to
the circuit, either as class A (style Z) or class B (style Y) circuit. For class A, no end-of-
line resistor is required. It is built into the circuit.
To ensure proper functioning, the jumpers must be set correctly for class A/B
selection.
Polarity shown is in activated condition.
Notification appliance circuit supervised and power limited.
X601: Class A (style Z) supervised output connection
X601: Class B (style Y) supervised output connection
* EOL resistance must be connected during non-use.
EOL resistance: 2.4 kΩ, 0.5 W
