General view:
This househol gas leaking etector have the most
a vance low-current gas sensitivity components that
enables etecting the gas leake in time an then sen
out the alarm signal.
1 - GREEN ON: working state
RED ON: alarm in icator
2 - RESET button
3 - Gas convection win ows

Connections:
Installation:
• Choose the proper position on ceiling to mount the etector, be sure that the istance to gas source is about
2m
• Fix the 86 x 86 box on the selecte place by screws, then fix the etector on it
ote: avoi installing the etector close to the following sources of interference: irect air flow form vents,
fans, oors, win ows, sources of steam, oil vapor, etc.
Relay delay setting:
To set the operating time of the relay after the alarm, unscrew an remove the top cover, then fin the jumpers
name “1” an “2” near the terminal blocks.
As efault setting, jumpers 1 an 2 shoul be connecte , which means that the relay will be activate
imme iately in case of alarm.
If jumper 1 only is connecte , the relay will be activate within 10 sec. after the alarm.
If jumper 2 only is connecte , the relay will be activate within 30 sec. after the alarm.
If no jumper is connecte , the relay will be activate within 60 sec. after the alarm.
Operating instructions:
The etector can be use in epen ently or to activate an external evice (e.g. the e-valves art. 30009091 an
30009092).
1A – In epen ently.
• Choosing a suitable position to install the etector accor ing to the INSTALLATION
• With 12V DC power supply an after the warm-up (the green LED flashes per secon uring this process), the
etector comes into normal etecting state
1B – To activate an external evice.
•Choosing a suitable position to install the etector accor ing to the INSTALLATION. Connect the external
evice with the contacts NC / NO of the output relay
•With 12V DC power supply an after the warm-up (the green LED flashes per secon uring this process), the
etector comes into normal etecting state
2 - While etecte the gas leaking, the re LED flashes, the buzzer sen s out the alarm soun an the relay will
be activate. The etector will resume to the etecting state when the gas ensity is lower than the alarm
level.
3 - The yellow LED on means the sensor insi e error. Please cut off the power supply an contact the installer.

4 - If the etector runs isor erly, cut the power off an rerun again. If still in error, please contact the installer.
Test:
To test the etector, you can give some gas aroun in istance of 5cm to the gas convection win ows by using
an ignition lighter. Gas testing frequently may result in re ucing the sensitivity of the etector. The alarm
ensity of gas is set accor ing with the criteria of GB15322-2003. The etector will stop alarm an resume
the etecting state while the gas ensity re uce .
Led information:
RED LED FLASH Gas leak
GREEN LED FLASH Warm-up
GREEN LED ON Work normally
YELLOW LED ON Insi e error
Maintenance:
The user must brush an clean the gas convection win ows with a little of cleanser every three months, avoi
the cleanser into the etector in the cleaning process an must retest the etector after cleaning.
otice:
•The etector must be installe an connecte correctly. It can not work if the power supply is misse
•Please perio ically maintenance accor ing to the irections
•Test the etector every half a year
•For various reasons, inclu ing, but not limite to, changes in environmental con itions, electric or
electronic isruptions an tampering, the pro uct may not perform as expecte . The user is a vise to
take all necessary precautions for his/her safety an the protection of his/her property.
Emergency treatment:
•Shut own the tube valve right away
•Open the win ow an make the air flow rapi ly
•Extinguish all fire sources an o not use anything can make fire (e.g.: lighters, matches, etc.)
•Avoi ing open/close all kin s of electricity
•Check the reason of gas leaking an notice the relative epartments an professional persons in time
