Power-Up Check
1.
Plug in any DC wallpacks that are being using with
individual intercom stations.
NOTE : If you plug in DC wallpacks after applying power to
the PS2001L or SPS-2001, you may get an overload
indication. This is because the stations that are being
powered by wallpacks will draw current from the units until
their own DC wallpack supplies are connected. To correct
the problem, plug in the DC wallpacks.
2.
Plug in the AC power cords for any connected PS-
2001L or SPS-2001 Power Supplies. The channel
status indicators should be green.
3.
If a channel status indicator turns red during
operation, locate the short or overload that is
causing the problem. Once the short or overload is
corrected, the Power Supply should reset itself and
the overload indication should go away.
