of 0.5m and 0.3m from the ceiling ( because of the gas is lighter than the air)
5.2.4 Diagram of installation location.
5.2.5 Locations to avoid
a
Steam, cooking fume, ventilation are present directly.
b
Close to air blowing heavily like doors, windows, exhaust fan and air inlet.
c
Close to shower room, plenty of steam, and power cut at night likely.
d
Explosion Proof place
e
Outdoor or where the temperature is below 0
℃
or above 55
℃
f
Object separates the detector from the gas appliances.
5.3
Wiring requirements
For 24V power cable, we suggest of wires which cross-sectional area is equal to or more than 2.5mm2, bv
type line;
Bus can be RVs flame-retardant copper core wires which cross-sectional area is more than or equal to 1.0
mm2.
5.4
Once combustible gas in the air reaches the set alarming level, the detector starts alarming, red
indicator flashes and rings a buzzer (twice per second); When the gas concentration is restored lower than the
set alarm, the detector can be reset automatically; Detectors accessing to the alarming system,
in about 15
seconds alarms will be informed to the controller.If the detector alarm fails to reset in 30 seconds, please
immediately cut off the gas source, open the window, it is strictly prohibited to turn on or off any electrical
appliances, and ask the qualify people to come to check and solve the leakage.
5.5 If the detector is flashing yellow light and ringing a buzzer(approximately every 3 seconds ),and the
detector can not be returned to the normal monitoring state after the self inspection button is pressed, it
indicates that the detector is faulty (sensor fault).This detector has no longer function of detecting leakage,
please contact the dealer;If the detector is connected to the controller, the detector will report the fault
information to the controller.
5.6 Operation buttons: Being pressed the self inspection button, the detector will be tested by itself (in the
sequence of lighting green, red, yellow, and accompany with a buzzer sound),it will enter to the monitoring
state after the end of the self inspection test.

Remarks
1
Alarm once
powered on.
Detector is powered for
the first time or power is
cut off for a long time.

etc.)
8.3 Do not allow the detector to be exposed in the decoration environment, please wait to complete the
decoration of the site , then the detector can be installed.
8.4 Please do not use the non calibrated concentration of the gas to test the product, ultra-high concentration
of gas will affect the lifetime of the detector, also endanger human health.
8.5 Please avoid long time for hard drinking or use heavily perfume, hair gel, moss, pesticides, gasoline,
alcohol, thinner, banana oil, paint and other volatile organic compounds to affect the normal monitoring of
the detector.
8.6 Do not cut off the power supply at will.
8.7 If the detector is out of power for a long time, it needs more than 5 hours to reset to normal application.
8.8 For your safety, please contact the dealer / service provider / manufacturer,it will conduct an inspection
according the specified gas sample and consentration once a year.
