Follow these guidelines when connecting VCM-4 speaker circuits:
3. Speaker circuits are supervised and power-limited.
4. Use twisted-pair cable for wiring speaker circuits.
5. Maximum speaker circuit wire resistance depends on wattage required for each
speaker.
6. Use only UL-listed speakers rated for 25 Vrms.
7. For systems with AA-100 amplifiers, you can use 70.7 Vrms speakers. Use 4.7K,
2W ELRs with 70.7 Vrms speakers.
8. Install End-of-Line resistors according to Table 4-11:
