HS120 Wiring
Connection to this station from the SS16 is done via RJ-45 plug. Connections to the audio transformer
are done by crimping onto the blue pig tail wires extending from the station. Privacy functionality is
supported by connecting the center tap of the 25V audio transformer to the yellow pig tail wire extending
from the station. When intercom is done to this station, the audio is fed directly to the speaker as long as
the handset is on-hook. As soon as the handset is taken off hook, the audio is immediately transferred to
the ear piece on the handset. The toggle switch on the front of the station provides a momentary call
position, and a maintained privacy position to mute the listen audio at the telephone.
