LED Sensor
Built into the SL-300 lantern, is a closed loop monitoring system for each LED within the lantern. In the
event of a single LED failure, the lantern can be configured to trigger the internal alarm relay which in
turn can be connected externally to trigger other devices, such as redundant light source.
Light Sensor
The SL-300 lantern has its own internal light sensor and whose day/twilight/night thresholds are
defined in LUX. These levels can be customised by entering in separate values as a measure of LUX.
The default values are 100 LUX (dusk), 150 LUX (dawn).
