Extremely compact optical indicator with a very high quality/price ratio that allows remote signalling of alarms, anomalies or others through highly luminous and low consumption LED. BZ versions incorporate a buzzer for intermittent or continuous optical-acoustical signalling (selectable by internal jumper). Power supply available at both 12V and 24V, selectable through internal jumper. The YELLOW LED ensures good visibility in all directions by emitting fixed or intermittent light. Simple and quick mounting thanks to the terminal connections and the possibility of fixing it with two-sided tape (included).
