4. Brightness Change („LIGHT“)
At the front, there is a brightness sensor that can be used to monitor light intensity.
The following command measures the current ambience brightness and sets the next-higher (!) threshold as refe-
rence. When this (higher) threshold is exceeded, alarm is triggered.
SET LIGHT #1513
The following command specifies the indicated ambience brightness threshold. When this threshold is exceeded,
alarm is triggered.
SET LIGHT <threshold> #1513
Threshold: 1 - 10 (1 = minimum sensitivity, 10 = maximum sensitivity)
Example: 1 = GX111 in a dark room will recognise light
10 = GX111 in a bright room will recognise additional light
Deactivate the alarm with the following command:
RESET LIGHT #1513
The sensor has a wider range than the human eye. Accordingly, observe light sources outside of the visible
range (IR = infrared and UV = ultraviolet), particularly in case of continuous wrong alarms.
The cap and its window for the sensor reduce sensitivity and the measurable spectrum of light. You need
to consider the effects depending on site of use; in any case, check that the alarm is triggered correctly at
the installation site of the GX111.
