This article describes how the loudspeaker connected to a TKIE-2 kit also can be used as a microphone.
Wiring diagram
Minimum loudspeaker impedance is 8 ohms.
ICX/AlphaCom configuration
The relays of the TKIE switches the loudspeaker. In idle the loudspeaker is connected to the mic input. When the relay is activated the loudspeaker is connected to the amplifier output.
To operate the relays, an event must be created with the TKIE-2 kit as the Event Owner:
In the example above the relays are controlled by the SET_IPRCO command. One can alternatively use the RCO command.
When the "Sub-event" = 62, this event will operate the relays when:
- M-key is pressed during a direct call
- Group call is received
- Audio Program is playing
- Alarm Message is received
