NOTE: Emergency Alarm ACK Encode is standard on Consolette models beginning with

System.
4.17 Headsets (L999_ Required)
Connections for up to two headsets are provided at the rear panel of the Consolette. The two RJ45
connectors are designed specifically for the Headset Jack Box (FHN7470_) in conjunction with the
Headset Amplifier Module Base with PTT switch (CDN6281). One Headset Interface Box is
required for each RJ45 headset connector on the Consolette. Standard Plantronics Headsets with
phono style plugs can then be plugged into the jack box.
NOTE: 1) The FHN7470_ Headset Jack Box kit includes cable kit (FKN8694A) which is
incompatible with the Consolette. This cable must be modified or replaced with a customer
supplied 1-to-1 cable between the Jack Box and Consolette Rear Panel Headset
connector.
2) Headset connections are only supported on Consolette models with a full featured front
panel. They are not active on limited front panel units.
4.17.1 Operation
When a Headset Interface Box is connected to the rear panel, the Consolette will mute the front
panel speaker. When receive audio is present from the radio, the Consolette routes the audio to
both headsets. The user can control the level of audio to the headset speakers by adjusting the
volume control knob on the O5 control head. When the PTT signal from either headset is pressed,
the microphone audio from the two headsets are combined and sent to the radio for transmit
operation.
4.18 PTT Footswitch (L999_ Required)
The Consolette provides two Headset connections one of which can be used with a PTT
Footswitch for hands free operation. A headset is connected to one of the RJ45 Headset
connectors to provide the microphone audio and speaker audio signals. The Footswitch is then
connected to the other RJ45 Headset connector. The user would have to modify the footswitch
connector to attach to the Consolette.Refer to the Consolette manual for pinout information.
Signals include:
• HDSTx_PTT - This is a logic input to cause the radio to transmit. The radio will transmit
when this input is pulled to less than 0.8VDC to ground.
NOTE: Enabling/Disabling Monitor is not supported on this interface.
