The Gas Detector can be used independently, or with
wired networks output functions.
1. Independently
(1) Choosing a suitable position to install the Detector
according to the INSTALLATION.
(2) With DC 12V or AC 220V power supply, the green LED
flashes once a second for about 3 minutes continuously,
that runs the inside sensor (warm-up state). After doing
that the green LED lights, that means the Detector comes
into normal working state.
2.In wired network
(1) Choosing a suitable position to install the Detector
according to the INSTALLATION. To connect the
Detector with the controller, with the N.C. or N.O. contact
optional accord with the controller system.
(2) With DC 12V or AC 220V power supply, the green LED
flashes once a second for about 3 minutes continuously,
that runs the inside sensor (warm-up state). After doing
that the green LED lights, that means the Detector comes
into normal working state.
3. While detecting the gas leaking, the red LED flashes, the
Buzzer sends out the alarm sound "Di Di", and output
the network signal. If the detector is connected with valve
or manipulator, it will drive them to shut off the gas pipeline
supply. The Detector will resume to the detecting state after
the gas dispersed.
4. For model series without driving manipulator ,it will enter
the test status when press the test button and exit when
loosen. For model series driving manipulator, it will enter
the test status after pressing the test button for more than 4
seconds. if less than 4 seconds, it is switch on /off the
manipulator function.
5. The buzzer long beeps and the yellow LED ON means the
inside sensor failure. Please cut off the power, and contact
the After-sales Service Center.
6. If the Detector runs disorderly, cut the power off and rerun

TEST
Suggestion: the user must brush and clean the gas
convection holes with a little cleanser every three months, and
must retest the Detector after cleaning for preventing the
cleanser into the Detector.
NORMAL MAINTENANCE
The Detector alarms while the gas density in air exceed the
alarm level. The relative treatments as below:
1. Shut down the tube valve right away.
2. Open the window and make the air flow rapidly.
3. Extinguish all fire sources and do not use anything can make
fire, e.g. lighters, matches, etc.
4. Avoiding open or close the power all kinds of electric
Equipment.
5. Check the reason of gas leaking, and notice the relative
departments and professional persons in time.
EMERGENCY ALARM TREATMENT
NOTICE
1. The detector must be installed and connected correctly. It
can not work if without the power supply orderly.
2. P l ease period ic ally mainten ance accord ing t o the
directions.
3. The detector must have a test every half a year.
4. For various reasons, including, but not limited to, changes
in environ mental conditions, elect ric or electronic
disruptions and tampering, the Product may not perform as
expected. The user is advised to take all necessary
precautions for his/her safety and the protection of his/her
property.
To test the installed detector while using independently or
in network, you can give some gas around in distance of 5cm
t o t h e g a s c on ve ct i o n h ol e s b y u si ng u n- i g n i t io n
lighter. Testing frequentl y may r esult in reducing the
sensitivity of the Detector. The alarm density of gas is set
according with the criteria of GB15322.2-2003.The Detector
will stop alarm and resume to the detecting state while the gas
density reduced to lower than the alarm level. The alarm
output switches can connect with the defense input switches of
alarm system.
