The optiPoint acoustic adapter is used for connecting
a headset (121 TR 9-5) (see Section 10.7.2)
●
an active loudspeaker box and a desk microphone via the Y cable
●
busy display/door opener and secondary bell/light paging, etc. (each with its own power
●
supply) via floating contacts (not supported when using the adapter on optiPoint 410 and
optiPoint 420).

Notes on the optiPoint acoustic adapter
The internal components of the optiPoint terminal are deactivated in speakerphone mode
●
if an external microphone and an external loudspeaker are used (sense lead).
optiPoint 500 basic does not support the connection of an external microphone to the op-
●
tiPoint acoustic adapter.
The speakerphone mode selection is independent of whether the internal or an external
●
speakerphone is used. External speakerphones have precedence over internal speaker-
phones with the exception of manual intercom and signaling procedures.
The internal microphone, the transmitter inset and any microphone connected to the opti-
●
Point acoustic adapter are muted in the "Mute" audio state.
Ring, alarm and key tones are transferred to the internal loudspeaker and not to an external
●
loudspeaker connected to the optiPoint acoustic adapter.
