Reflector for middle distance (foil) DLR1192 and reflector for short
distance (foil) DLR1193
The reflectors for middle distance and for short distance consist of a foil with micro-
prismatic elements, which are formed in a transparent, synthetic resin, sealed and
mounted on a plastic base. The foil has the same principal effect as the prism.

3.3.3 Line separator
All FDnet/C-NET devices are equipped with a line separator.
The FDnet/C-NET device is equipped with electronic switches which isolate the
defective part in case of a short-circuit on the detector line. The rest of the detector
line remains serviceable. On a loop line all FDnet/C-NET devices remain fully
functional after a simple error.
3.3.4 Danger levels
The detector can transmit the following danger levels to the control panel:

collective detector line, only danger levels 0 and 3 can be transmitted to the control
panel.
