The detectors have a function of signalling statuses by means of five LED indicators located on the side of
the housing (see Figure 2 and 3).
Indicators are grouped in two fields:
DETECTOR (information concerning the
detector),
BUS (information concerning the detector
connections).
Figure 3: User interface
Table 3 describes the way of signalling the states of the detector operation. Detailed description – see
Section 1.2.

6 System architectures
Detectors can be connected in two ways:
star system (traditional) or,
into a serial "bus" arrangement (alarm loop) – open or closed.
Systems can be built of single Alpa EcoWent XT detectors or pairs (Alpa EcoWent XT along with the Alpa
EcoWent XT detector).
