Device configuration

Detector location
For correct operation of the system, it is necessary to configure the detectors by appropriately setting the
configuration switch SW2 located in the detector (see Figure 1, 6).
Two setting possibilities are distinguished:
last detector – switch setting for detectors working in the star-shaped system or the last detector
in the connection in the open alarm loop system,
intermediate detector – switch setting for detectors working in the system of a closed alarm loop
and detectors working in the open alarm loop system except for the last detector.
