7.PRODUCT INSTALLATION
•The product is only for indoor ceiling installation;
•The Gas Sensor is suitable for natural gas detection;
•It is recommended to mount it in a location directly above the gas source
Ceiling
Ground
Gas stove
Gas sensor >1.5m<3m
900
*The area marked with grey
is recommended for installing the sensor
Functionality:
1.Turn on the power of the sensor. If the yellow LED flashes once and the
buzzer emits a short sound, it means that the sensor is in preparing state. If
red, green, and yellow LED flashed alternately and the green LED remains
on, the sensor is working normally.
2.In normal working mode, you can press the button to perform a self-test of
the sensor. The buzzer will emit a short sound and the red, green, and yellow
will flash in sequence until the green light will remain permanently on
(returning to normal working mode).
3.If a gas leakage is detected, the red LED will flash, the buzzer will emit a
repeated sound and you will receive an alarm notification on your
smartphone. The alarm will stop if there is no more gas detected.
4.If the yellow LED is always on and the buzzer emits a continuous sound, the
sensor is faulty.
•Fix the bracket to the wall with screws or 3M tape, Fix the sensor into the
bracket by rotating it clockwise. If you use 3M tape, please make sure the
wall surface is firm, smooth, and clean.
•Screw installation is recommended. The user is responsible for any
accidents and safety incidents caused by poor installation.
5.If fault is detected, turn off and than again on the power. The sensor will
start a self-test. If the fault alarm still persists, remove the sensor and repair
it or replace with a new one.
Important notes
-If the mounting location is unconventional (different from the recommended
installation in the diagram), check carefully for the best position that ensures
an effective monitoring of potential gas leakage.
-In case of house decoration, the gas released by solvents or paint can
damage the sensor and can cause false alarms. When decorating try to
protect the gas sensor from dust and vapors of any kind. Open the doors and
windows to maintain a good ventilation and, if possible, remove the sensor
temporarily.
-Do not install the sensor too close to the gas stove, heating and smoke can
affect the normal working and sensitivity of the sensor.
-Avoid long-term exposure to liquid vapors and soot.
-Avoid liquid spills or high humidity locations.
-Avoid installation in high or low temperature environments (not higher than
55°C or lower than -10°C)
-Avoid mounting the sensor in an environment with the following gases:
silicone vapor, formaldehyde, toluene, acetic acid, and hydrogen sulfide.
These are mainly produced from home decoration, decorative materials,
adhesives, paint, hair gel, silicone, etc. These gases can cause irreparable
damage to the sensor, leading to false alarms or failure. In addition, high
concentration of alcohol vapors can lead to a false alarm and can decrease
the long term sensitivity of the sensor.
-The sensor will send an audible, visual and push notification when gas is
detected.
-Do not test the sensor with open flame to avoid damaging the product.
-If alarm is sent during the test, it warns you of potential danger and needs
immediate attention. Never ignore any alarm, which may lead to casualties
or property damage.
-If the sensor fails self-test, please refer to “Troubleshooting” part of the
manual. If the fault can not be fixed, the product should be replaced
immediately.
Daily maintenance
-Test the sensor periodically.
-Keep the sensor clean and without dust. You can clean it with a vacuum
cleaner and a soft fabric material or a soft brush.
-Do not let solvents or cleaning agents inside the gas sensor. It can cause
damages to the sensor. After cleaning, perform a test of the sensor.
-Do not paint the sensor, it can affect the normal operation of the product.
8.TROUBLESHOOTING
-If the sensor is not reacting, check if the sensor is properly installed and is
powered correctly.
-Re-position the sensor if there are many false alarms.
-Try to clean the sensor if there are many false alarms.
9.WARNING
-In case of gas leakage alarm, take all appropriate measures:
oClose the gas pipe valve.
oOpen the windows and doors.
oExtinguish possible fires sources, such fireworks, lighters, matches.
oDo not turn on any electrical appliances.
oOnly if safe to do, check the reason of gas leakage and promptly notify the
relevant departments or professionals to deal with it.
-Do not leave the product in extreme high temperature environment.
-Do not disassemble the sensor, it will cause the warranty to be lost.
-Keep out of reach of children.
