Control contacts (inputs/outputs)
The 48 control contacts (digital I/O) can be used for controlling voice alarm system components or for
connection to other systems, such as a fire alarm control panel. The function of the input or output can be
individually programmed in the configuration for each control contact.
The reference potential for the control contacts is available at the four GND terminals.
Contacts 41 – 48 are also suitable for monitoring the connected line for short-circuit or line interruption.

 Input with switch contact
The input is switched to GND and tripped by
closing the external, potential-free contact.
 Input with line monitoring
The "line monitoring" function can be
activated in the configuration for the control
R2
outputs 41 to 48. In this case, the connected
680Ω
line is monitored for wire break and short-
circuit.
Connection to external monitoring resistors
(R1/R2) is required for this function.
An active output switches to 0V / GND.
