Power

The S101A and S102A Speakerphone requires either AC or DC auxiliary power from one of the sources listed the ADJUNCT POWER section of this manual. Power from the source supply is applied by way of the voice terminal’s mounting cord and the speakerphone’s connecting cord. The S102A draws its power from the system switch through the associated voice terminal; it does not require an auxiliary power source.

The 4A Speakerphone requires auxiliary power from one of the sources listed in the ADJUNCT POWER section of this manual. The power from the source supply is applied to the loudspeaker set and the transmitter through an adapter or connecting block provided with the 4A Speaker- phone.

Considerations

A speakerphone and a headset adapter cannot be connected to the same voice terminal simul- taneously.
