FUNCTIONALITY OF ONBOARD BUTTON
The button on the device is used to perform a function test of the outputs and to switch the
device on or off. Pressing the button for about 1 second, upon release, a LED and buzzer
test will be performed.
Important:
Do not use lighters or combustible gas directly on the sensor to test its
functioning, since the high concentration of gas pollutes the sensor itself, varying the
sensitivity and decreasing its duration.
SLEEP MODE
Keeping the button pressed for more than 6 seconds the sensor will no longer carry out the
gas analysis (the yellow LED will flash for 200 ms every second to signal that the gas
detection is deactivated). To enable detection again, press the button for 6 seconds. The
green LED will light up to indicate the resumption of operation.
Important:
After having powered the sensor or after having rehabilitated the detection by
pushbutton, it is necessary a 3 minutes waiting time for the detection of explosive gases,
and a time of 20 minutes for the detection of harmful gases. During this period the yellow
LED flashes, to indicate the preheating phase of the sensors and the environmental
analysis.
In the event of an anomaly or of operation in extreme temperature conditions, the yellow
LED will light up permanently.
ACTIVE SECURITY – RADIO 433 MHZ
The device has a 433 MHz radio transmitter, which allows, through the installation of a
special radio receiver, to secure the environment, for example by controlling a solenoid valve
that closes the gas in case of loss. It also allows you to install multiple detectors with just
one receiver, so you can secure the whole house.
INSTALLATION
We recommend positioning the sensor at 50 centimeters from the ceiling if the gas to be
detected is mainly composed of methane and gas lighter than air, while we recommend a
height of 50 centimeters from the floor if the gas to be detected consists mainly of butane or
other heavy gases. For rooms below 15 square meters, a medium height from the floor is
recommended. For proper ventilation of the sensor, it must be placed in a vertical position,
with free ventilation grids.
