2. Installation
A. Installation requirements
   a. Alarm installation location: it should be installed **4 meters away within a radius of gas source and placed in a well ventilated place
     1) Natural gas is lighter than air, and it should be installed in the location where is about *0 cm from the ceiling. (Liquefied gas is heavier than air, so it should be installed in the place where is about *0 cm from the ground.)
     2)It should be placed in about one meter straight-line distance away from the edge of range hood and stove.
    b. Banned installation location: the corner, the cabinet where the air cannot circulate easily; the location where the lampblack and the water vapor can smoke directly, such as, the place where between the stove and range hood, right above rice cooker, etc.
c. Banned installation time: A. Painting and decoration of the house is not finished. B. The house is decorated, but general ventilation is less than ten days. C. The house was decorated with wood furniture or new wood furniture will be purchased, and the general ventilation is less than five days. D. Use spray (mosquito, cockroaches, etc.), air cleaner, glue, paint, alcohol, hair gel, and the general ventilation is less than four hours. E. It contains Hmds, but is not completely clean. (Note: Hmds is usually called silicone resin. It can cause the precious metal poisoning, and it can make a sensor probe completely lose its alarm function, even if its content in the air is less than ten thousandth.)
d. The consequence which is caused by illegally using the alarm on the banned installation location and in the banned installation time will be borne by the user and the installer.

Minor consequence means reducing the sensor service life, and serious consequence is to damage the detector. Such as the following circumstances:
1) False alarm: In the case of no gas leakage, the red light flashes and the buzzer keep barking.
2). Gap-type alarm: In the case of no gas leakage, the detector alarms for a moment, and then stops, and then alarms again, repeating like this, and such phenomena most happen at midnight.
3). Sensor failure: Yellow light flashes, buzzer barks in ‘beep’.
4). No alarm: In the case of gas leakage, the detector has no any response; it becomes a veritable decoration.
If the detector was installed in the banned installation time, please turn off the power for the detector, and protect the alarm with plastic bags, then open the alarm after the requirement of ventilation time has been met.
B. Installation steps:
a. Mark with oil pike or pencil on the drilling place on the installation location which complies with the installation requirements.
b. Firstly, penetrate ceramic tile with ï¿ 8mm    hollow tubular diamond drill bit (it is also called glass drill bit). (It is sold in electric tools store in decoration)
c. Drill the hole on the wall with ï¿ 6mm electric hammer, and the depth of the hole is about *9mm.
d. Put the white plastic plug into the hole, and the edge of the plastic plug levels along with the ceramic tile surface.
e. Screw into the plastic plug with two ï¿ 3.5mm black screws, and fix the detector chassis on the wall.
   f. Hang and buckle the combustible gas detector on the chassis; it should be smooth and steady and looks beautiful.
   g. Connect to other equipments, and check to see whether it is correct or not, plug in, and then the installation is finished
Notes:
1) The alarm should be installed in the place where it can be easily check and with gas leak.
2) Do not use high concentration gas to inspect the machine, which is to avoid damaging the alarm and reduce its service life and may endanger human health.
3) During installation, it is strictly prohibited to vibrate, drop, impact the product, otherwise it will fail.
4) The alarm cannot be installed at large airflow place.
5) The alarm cannot be covered by other objects.

   c. K1 key: it is also called self-checking / testing key, short-press means detector self-checking, and long press means function testing.
4. Application ï¼š
A. Connect power supply: the speak sounds “tick”, the concentration unit light, all digital tube light: *8 *8.8ï¼Œafter three seconds, the green light starts flashing 1 time/second, then the alarm is in warm-up state: ***-.-, the green "*1 " indicate that detector already used for one month. The warm-up time is about **3 minutes.
B. After warm-up, the green light is on; the green digital tube shows the current used month, the red digital tube shows the current concentration: *1 0.0, meanwhile the detector enters normal monitoring state now.
C. Normal monitor state: Use and setting of detector functions:
a. system self-test: In normal monitoring state, press K1 key shortly ,the green, yellow and red lights run in a cycle with alarm sounds output.
b. function test: In normal monitoring state, long press K1 key, the green, yellow and red lights flashed at the same time ,and the detector output some signals, such as: close valve signal, close or open manipulator signal, networking signal, wireless transmitting etc.
c. alarm record query: in normal monitoring state, press K2 key shortly; the detector will send out "tick" sound . Then you can check alarm record from back to forward, and total 8 times alarm records, the query sequence is: No.8, No.7, No.6, No.5, No.4, No.3, No.2, No.1
Alarm record display:
      Recording Number: No.8, No.7, No.6, No.5, No.4, No.3, No.2, No.1.
      Alarm happening time(such us):*1 **0(the used month and hour when it alarm)
      Alarm happening time from the current(such us):*0 **1(the used month and hour from the current when it alarm)
       The set value of alarm point(such as): 5.0 KPPM
d. Setting of concentration unit: in normal monitoring state, press K2 key for a long time , when detector send out "tick" sound once, the concentration unit of KPPM and LEL will automatically exchange. then the detector will display the switching result (unit: KPPM or % LEL).
e. Current alarm point query: in normal monitoring state, press K3 shortly and the screen will display current alarm point.
f. Setting of alarming point(unit state: KPPM):
1)In normal monitoring state, press K3 key for a long time; after the speaker ticks for two times, the screen display current alarm point, then the detector enters the setting of alarm point: the last number of concentration display beating, press k2 key once with number increase of 1, and press K1, the cursor removes one cell; after completion of setting, press K3 to confirm and exit , or the detector automatically confirms and exists; after this, the detector will display the setting results of alarm point with beating, and then enter normal monitoring state.
2)If the alarm point is set too low; after warm-up, it has been in alarm state, lead to you can't set the alarm point. You can press K3 for a long time during warm-up state, and directly enter the alarm concentration setting, and the methods are as like above.
3)The setting range of alarm point: generally **9.9 KPPM (i.e. ***9.8 ï¼…ï¼¬ï¼¥ï¼¬), from the perspective of safety, if the set value of alarm value is greater than 6.0KPPM (i.e. *2%LEL), the detector will automatically turn the alarm point to 6KPPM (or ï¼‘ï¼’ï¼…ï¼¬ï¼¥ï¼¬) after *0 minutes.
D. Alarming state: any key is invalid in alarming state.
a. alarm: if the test gas is leaking, the red digital tube of detector displays the current gas concentration, when the concentration reaches the setting alarm point, the red light flashes and the green light is off, and the speaker gives out a harsh of sirens to remind you : the gas leak! Only when the gas concentration is decreased below the alarm point, the alarm sounds gradually stop and return to normal monitoring state.
b. alarming output: when the detector alarm, there are below items you can choose except for output sounds and light :
