Sensors
Battery sensors
The SL-155 series of lantern continuously monitors its input voltage using three finable
thresholds.
• For voltages greater than “OK” level, the lantern reports via IR Remote control requests
or the GSM that the input voltage is satisfactory.
• For voltages below “low” the lantern can be configured to operate the internal alarm
relay and /or reduce the intensity level by 25% as a measure to extend the operation of
the lantern until it reaches the “Fail” voltage.
• At “Fail” the lantern shuts down entirely, and turns of the GPS and the mains LEDs. The
lantern will only commence operation once the input voltage has exceeds the “OK”
voltage level. The three thresholds: Flat, Low and OK are user definable.
Temperature
The SL-155 utilises two temperature sensors. One on contact with the LED heat sink and
second that monitors the internal temperature within the lantern.
Each sensor has two user configurable boundaries. At the “low” boundary temperature
point, the lantern intensity is reduced by 25% to help reduce the heating of the housing.
Reaching this point does not trigger the alarm reply. The second boundary is “high”, where
at which point, the lantern turns off and triggers the alarm relay.
