Installation and User Instructions

1.2.3 Loudspeaker/Control Inputs (3)

This 6-pin connector provides the connection to a

loudspeaker and to two control inputs.

The control inputs can be configured to act on contact

make or on contact break (see section 43.4.7 of the IUI

Praesidio 4.0). It is also possible to supervise the cables

for short-circuits and open connections (see figure 1.6

and figure 1.7). Whether a control input is actually

supervised or not is defined in the configuration.

1.2.4 Headset/Volume control (4)

This 6-pin connector provides the connection to the

headset and the volume control. This volume control

also controls the volume of the loudspeaker connected

to connection 3.

A linear potentionmeter R (typical value: 100 kohm) is

used to create a control voltage from the supply voltage.

If a volume control is not needed, pin 2 and 3 must be

connected to each other. The volume level of the

earphone or loudspeaker is then at its maximum.

Warning

Do not connect DC or AC signals to the control

inputs, otherwise the input circuit may be

damaged. Only use voltage-free contacts.

Note

Do not combine control input wires of multiple

control inputs (e.g. do not use a common return

wire).
