1) All speaker circuits are supervised and power-limited.
2) Twisted-pair cable should be used for speaker circuit wiring.
3) Maximum speaker circuit wire resistance is dependent upon wattage
required at each speaker.
4) Refer to the table, Resistor Requirements, for resistor values.
5) Use only UL Listed speakers rated for 25 V
RMS
