TEST

To test the installed detector while using independently, you can give some gas around in distance of 5cm to the gas convection holes by using un-ignition lighter.

Testing frequently may result in reducing the sensitivity of the detector. The alarm density of gas is set according with the criteria of GB15322.2-2005.The Detector will stop alarm and resume to the detecting state while the gas density reduced to lower than the alarm level.

NORMAL MAINTENANCE

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.

EMERGENCY ALARM TREATMENT

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.
