Connect the Interrogator 200 AVM to the panel terminals as shown in Figure 13

Caution: If a speaker is already connected to panel terminals 7 and 8, the
Interrogator 200 speaker must be hooked up in series with that speaker to
provide a 16-ohm load. Hooking up speakers in parallel to panel terminals 7 and
8 creates a 4-ohm load that can cause permanent damage to the panel.
