Types of Light Signal
N1 can send out four types of light signal:
• Green signal: occurs periodically, it means that the device is
functioning properly and there are no anomalies or pollutants
detected (see Ch. 3, § AUTO-TEST).
• Yellow signal: occurs in case of detection of higher levels of one
or more of the pollutants monitored before they reach the danger
threshold (“CAUTION”) Simultaneously N1 emits the voice message:
“Presence of (name of pollutant)” (see § above TYPES OF VOICE ALARM:
CAUTION AND DANGER).
• Red signal: occurs when the level of one or more pollutants reaches
the threshold of danger, in case of “DANGER”. N1 simultaneously
sounds the alarm and the voice message: “Danger, high presence of
(name of pollutant)” (see § above TYPES OF VOICE ALARM: CAUTION
AND DANGER).
• Blue signal: warns about malfunctions, for example, problems with
Wi-Fi connection, battey, sensors.
• Violet signal: indicates that punctual measurement has stated (see
ch.3 § Opeating Modes).
