Power-Up Check

Plug in any DC wallpacks that are being using with indi-

vidual 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

their own DC wallpack supplies are connected. To correct

the problem, plug in the DC wallpacks.

Plug in the AC power cords for any connected PS-2001L

or SPS-2001 Power Supplies. The channel status

indicators should be green.

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.
