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.
