vided by the Audio Input/Output Card in slot number 8.

Therefore, if your intercom system uses fewer than ten

Audio Input/Output Cards, make sure that slots 9 and 8 are

filled in any case. Also, never remove cards 9 and 8 at the

same time as the intercom system will cease to operate.

Note

When a front or back audio card is removed, the displays

on any keypanels connected to that card will display aster-

isks instead of the normal key assignments. After a card is

reinstalled, it may take a minute or two for the keypanel

displays to return to normal.

3.3 Unused Back Card Slots

To ensure proper air flow, each unused back card slot

should be fitted with a card blank (part number 9000-

7467-003) to cover the opening.

3.4 Master Controller Card DIP

Switches

As shipped from the factory, all master controller card DIP

switches are set to the “off” position for default operation.

These settings will be satisfactory for most applications. Op-

tional settings are summarized in Table 1, page 9. If any

changes are made to the settings, make sure that both the

main and backup controller cards are set the same.

4 Power Supply

Removal/Installation

Place the power switch on the front of the power supply

in the off (O) position before removal. Loosen the two

captive thumbscrews on the front of the supply, then

grasp the screws to pull the supply out.

To install a power supply, set the power switch on the

front of the supply to the off position. Push the power sup-

ply firmly into the slot in the ADAM frame so that the

connector seats, then tighten the captive screws.

5 AC Power Connection

1. Place the AC switches on the back panel of the ADAM

frame in the off (O) position.

2. Place the power supply on/off switch on the front of

each power supply in the off (O) position.

3. Connect AC power to both of the AC jacks on the back

of the ADAM Frame. Connecting both AC inputs will

assure continued operation 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.

6 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.

1. Place the AC switches on the back of the ADAM

Frame in the “on” position.

2. Place the ALARM OVERRIDE switch on the front

panel in the on position. The alarm should sound

while the power supplies are off.

3. Place the on/off switch on the front of each power sup-

ply in the “on” position. The POWER GOOD indica-

tors and all voltage indicators should light. The fans

should turn on. The alarm should shut off.

4. 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.

7 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 but-

ton is the red LED fail indicator. The LED indicator re-

mains off during normal operation. If the fail indicator

turns on, first attempt to restore normal operation by mo-

mentarily pressing the reset button. Allow 15 to 30 sec-

onds for reset. If the fail indicator does not turn off after

this time, replace the affected card.

8 Alarm Operation

If there is a power supply fault during operation, the audi-

ble 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 posi-

tion. Turn off the defective power supply, and repair or re-

place it as soon as possible to assure continued backup

protection in the event of another power supply failure.
