Unimode 400 Installation PN 50710:A 10/22/97
When wiring eight speaker circuits using 180 watts of power, note the following:
1. AA-30 audio power is drawn from plug P6 or terminals 6 and 7 of terminal block
P8. This audio power run is not supervised. If using the optional supervised return
(plug P7 or terminals 2 and 3 of block P8), a loss of audio power due to a break in
the wiring will generate a trouble signal at the AA-30.
2. If using an optional supervised four-wire return, cut resistors R8 and R9 (for the
location of R8 and R9, see Figure 4-37).
3. Each circuit can handle a maximum of 30 watts.
4. In this configuration, cut VCE-4 and VCM-4 jumpers JP1 and JP2.
Figure 4-37 shows typical wiring for a 180-watt, eight-speaker circuit:
