Table 5: Configuration example PW-089-X – meaning of the device indications
The foregoing configuration is merely an example of the device capabilities since its design features enable
versatile operation of the device with the following operation modes:
assigning various groups and combinations of field detectors to every single light segment
(definition of monitored sub-areas)
assigning various warnings and alarms to light segments:
•
exceeding of alarm thresholds,
•
indication of failures affecting individual detector(s) or the entire monitoring system,
•
indication of other specific operation modes (calibration, heating up, etc.)
two operation modes of each light segment: solid-on (continuous) or blinking,
operation of the audible alarm (siren) with different intensity, depending on the status of
warning /alarm signals.
5.3 The field of the signaller own states
Section 1 of the signaller comprises two pilot LEDs that indicate status of the device (see Figure 2).
Operation of these LEDs for PW-091-S-X / PW-089-S-X and PW-091-M-X / PW-089-M-X units is described in
the table below. For the PW-091-C-X / PW-089-C-X unit these LEDs are inactive.
Controls Description
Operation (green) Continuous signalling – correct operation of the device
Failure (yellow) Continuous signalling – critical failure of the device, please contact with the manufacturer
