Description

1.The leak detector does not alarm ,why ?
When Display 5.6.7.8.....LPG/Natural Detector Speaking Alarm Sounds.Gas concentrations below 5% LEL,the number of displays below 5,the detector will not alarm.
Alarm density is 2500PPM(1500PPM) Alarm Set point :5% LEL.Alarm Sound Level: 80-85dB at 1m.
2.The natural gas detector warming-up,green and yellow light flash,how to do ?
Plug again the detector, when in preheating state, press the test button within 5 seconds until it changes to three led lights flash .
3.How to change language?
In the state of warm-up, short pressing test button can switch language.
4.How to operate correctly ?
1.Plug in the detector with 110~250V power for preheating, need to wait 3 mins.(power cable long :74.4inch)
2.When in the preheating status,digital display shows 180 seconds countdown,three led lights flash,red lampshade flashing,the real human voice broadcast function.
3.Please note: DO NOT press any button When preheating.And do not apply gas to test during preheating since the gas will not be detected.
4.Preheating finished,detector enters into normal working state.The green led light is always on.The digital display shows"0" if there is no gas in the air.
5.How to test easily ?
1.We can do product self-test. When in working state,press test button,three lights and red lampshade flash and there is a voice prompt .It is the analog alarm.
2.Do Testing,we can use a lighter and close to the air inlet then let a little gas release, and product is alarming .You can see the gas value in the display is rising. Green and red light is fast flashing
we can hear sound alarm and real human voice broadcast .Because the lighter gas concentration is more pure .Once the gas concentration is higher than 5%LEL , detector will be alarming until the the value is falling and under.
