Ac Power Connection; Adam Frame Power-Up; Circuit Card Reset And Fail Indication; Alarm Operation - RTS KP-12 System Installation Manual

AC Power Connection

To install a power supply, set the power switch on the front of the supply to the OFF position. Push the power supply firmly
into the slot in the ADAM frame so that the connector sits properly in the slot, then tighten the captive screws.
AC Power Connection
Place the AC switches on the back panel of the ADAM frame in the OFF (O) position.
1.
Place the power supply ON/OFF switch on the front of each power supply in the OFF (O) position.
2.
Connect AC power to both of the AC jacks on the back of the ADAM Frame.
3.
Connecting both AC inputs will assure continued operations of the ADAM Frame in the event that one power supply fails.
If desired, two separate AC power phases may be connected. This will protect not only against a power supply failure, but
also against a loss of power to one phase.

ADAM Frame Power-Up

NOTE: For proper power supply loading, at least two front cards should be installed in the frame before turning on the power
supplies.
Place the AC switches on the back of the ADAM Frame in the ON position.
1.
Place the ALARM OVERRIDE switch on the front panel in the ON position.
2.
The alarm should sound while the power supplies are OFF.
Place the ON/OFF switch on the front of each power supply in the ON position.
3.
The POWER GOOD indicators and all voltage indicators should light. The fans should turn ON. The alarm should shut
off.
While the intercom system is initializing, the red LED fail indicators will be lit on all circuit cards. Allow 15 to 30 seconds for
all indicators to turn OFF.

Circuit Card Reset and Fail Indication

Each front card is equipped with a reset button located near the top-front of the card. Directly under the reset button is the red
LED fail indicator. The LED indicator remains OFF during normal operation. If the fail indicator turns ON, first attempt to
restore normal operation by momentarily pressing the reset button. Allow 15 to 30 seconds for reset. If the fail indicator does
not turn OFF after this time, replace the affected card.

Alarm Operation

If there is a power supply fault during operation, the audible alarm will sound and one or more indicator lights on the affected
power supply will turn OFF. To deactivate the alarm, set the ALARM OVERRIDE switch to the OFF position. Turn OFF the
defective power supply, and repair or replace it as soon as possible to assure continued backup protection in the event of
another power supply failure.
NOTE: The power supply alarm will also sound if a power supply is turned OFF. This is normal. Either turn ON the power
supply, or turn OFF the ALARM OVERRIDE switch.
