Wiring the Loudspeaker

A 16 Ω Loudspeaker may be connected between the LS terminal and the Aux +

terminal.

Wiring the Zones

The zones on the Accord xpC can function in one of three modes; Normal Closed,

Double Balanced and U.S. End of Line. Zone wiring for the three modes are illus-

trated below. The mode of operation for the zones is programmed from Group 5 —

Option 9 Zone Configuration.

It is strongly recommended that the maximum cable run on each zone is 100 m.

Figure 2.6 Zone Wiring for Double Balanced Zones

Figure 2.7 Zone Wiring for US EOL Zones

Zone Links

The eight zones, the zone tamper and the bell tamper circuits can be shorted using the

Zone Links provided in the ancillaries pack. It is strongly recommended that this be

done if any of the circuits are not to be used. If Double Balanced or U.S. End of Line,

fit a 1K resistor across the zone and not the shorting link.
