Figure 4. A two-channel Audiocom intercom system powered by a PS2000L Power
Supply. The power supply is set to isolate mode. In this mode, each channel is a
separate party line, and current per channel is limited to 1 amp. Note that both
single- and two-channel intercom stations may be connected by using “Y” cables
(or JB2 Junction boxes). Prefabricated cables may be used, or cables may be
constructed using Figure
