Intended use
The input/output module has two inputs/outputs and is
operated on the FDnet/C-NET. The inputs/outputs can be
connected as follows:
– Collective detector lines and conventional detector lines
– Control line
– Contact input
Housing FDCH221 is available to protect the module from
environmental influences like moisture and humidity.
Mounting the input/output module
The input/output module can be mounted as follows:
– In a fire control panel using the mounting feet supplied
on a U-rail TS35 (Fig. 1)
– In a housing FDCH221 available as an accessory
(Fig. 2...4)
