Inputs
Two programmable inputs (IN1 and IN2) have been provided on this assembly. Inputs IN1 and IN2 can
be programmed to perform a variety of functions such as: initiating dialing, changing button functions,
initiating alarms, etc. Termination of the input contacts have been provided on terminal block P44 pins 1-
4 (IN1 +/-, IN2 +/-).
N OTE : Input IN1 is shared with the footswitch and SW1 inputs; therefore, this input can only be used
when the footswitch and SW1 are not in use. Input IN2 is shared with the SW2 input, therefore, this input
can only be used when SW2 is not in use. Please refer to the “Inputs” section of the central cabinet
instruction manual for instructions on how to program these inputs.
Footswitch
A programmable footswitch input has been provided on this assembly. Termination for the input contact
has been provided on terminal block P45 pins 7-8 (footswitch +/−). The footswitch can be programmed
to perform a variety of functions such as: talk/listen control (T button function), direct dialing, etc. The
footswitch input shares the programmable input IN1 with SW1. Either the footswitch can use
programmable input IN1 or SW1, but not both.
N OTE : The function of input IN1 must be programmed in the central cabinet. Refer to the “Inputs”
section of the central cabinet instruction manual for instructions on how to program this input.
Outputs
Two programmable opto-coupler outputs (OUT1 and OUT2) have been provided on this assembly.
Termination for the output have been provided on terminal block P45 pins 2-3 [OUT2 (−), (+)] and pins
4–5 and [OUT1 (−), (+)]. Outputs OUT1 and OUT2 can be programmed to perform a variety of
functions such as: conversation active, loudspeaker active, PA announcement, pre-defined conference
active, all call or group call received, door opener, etc. Please refer to the “Outputs” section of the central
cabinet instruction manual for instructions on how to program these outputs.
Refer to Figure 13 for a typical system interconnection.
N OTE : The outputs can only be used when the station is powered by 24 V.
