8 Transponders and loop elements
„Contact, gen. (monitored)”
- To connect contacts that are to be monitored
- Multiple contacts can be combined in a detector
zone
- Mandatory-reset contacts may not be connected
“Contact, gen. (non-monitored)”
- To connect contacts that are not to be monitored
- Otherwise, as for “Contact, gen.(monitored)”
In the case of VdS systems, when connecting a threshold monitored line, the last detector
with an "S24218-G44-A1 line termination" must be closed. Normal closed (NC) contacts can-
not be connected when monitored.

Input/output module FDCIO222 (FDCI222)
The FDCI222 input module has 4 inputs.
The FDCIO222 input/output module also has 4 potential-free outputs.
Since the inputs are not monitored for creeping wire breakage and short-circuit, in systems
based on the VdS standard the module must be attached immediately next to the contact be-
ing monitored.
Overview of configurable and switchable inputs.
