Channel Capacity: When connecting intercom stations to the SPS2000A, determine the total current for all stations on each channel. The total per channel should not ex- ceed 2A. If you exceed this limit, the SPS2000A will provide an overload indication. - Page 7 Figure 2. Audiocom / Clear-Com Selector Switch (Top Cover Removed) Note that if you are using DC wallpacks with some intercom stations, you do not need to add the current consumption of those stations to the total current.

Page 11: Power-Up Check
Power-Up Check 1. Plug in any DC wallpacks that are being used with individual intercom stations. If you plug in DC wallpacks after applying power to the SPS2000A, you may get an overload indication at the SPS2000A. This is because the stations that are being powered by wallpacks will draw current from the SPS2000A until their own DC supplies are connected. - Page 12 If a channel status indicator turns red during operation, try correcting the prob- lem by pressing the reset button on the front of the SPS2000A.
