The following wiring diagrams show how 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 needed. It is built into the circuit.
To ensure proper functioning, the jumpers must be set correctly for class A/B
selection.
In the diagrams below, polarity is shown in activated condition.
Notification appliance circuit supervised and power limited.
