DC Powered Wire-In Combustible Gas Detector
Outline
Combustible gas detector ( hereinafter referred to as detectors ) uses advanced microprocessor technology with high quality long-life gas sensor was developed for leak detection gas, natural gas and other combustible gases to the combustion gas leakage occurs , explosion, poisoning and other accidents can be safe and early detection alarm detector with high sensitivity, good reliability, anti- tobacco, anti-alcohol and automatic temperature compensation function, widely used in homes , hotels, apartments and other needs of the combustible gas leak safety monitoring sites .
Features
Semiconductor gas sensor , stable, long life ;
Small size , easy to install , easy to use ;
Multiple alarm signal output mode , can be easily and fire , security and other systems connected with .
Performance parameters :
One . Performance:
Operating voltage : DC9 ~ 28V ( adaptive , non-polar )
Power consumption: normal monitoring ≤ 2W, alarm status ≤ 3W
Output Capacity and Control:
List of reference detector .
Alarm concentration:
Natural gas : 7500ppm (15% LEL)
LPG : 2000ppm (10% LEL)
Artificial gas : 800ppm (2% LEL)
Sensor life: 5 years
Use of the environment :
Temperature : -10 ℃ ~ +50 ℃,
Relative humidity ≤ 95%, non-condensing
Dimensions: Diameter 103mm × height 55mm
Shell protection grade : IP30
Housing material and color : ABS Ivory
Two . Use and operation
1 Preheat the power :
After the probe is energized , it will issue a "beep " sound , which means that normal power ; then the yellow light starts flashing , which means that the detector into the warm-up phase , the detector warm-up duration of 30 seconds to 5 minutes , the end of the warm-up after the detector goes off lights , and issued a " drip , drip, drip " three times , which means that officially enter the working state , the red indicator light flashes once for about 5 seconds , which means that the detector is in the detection state. Gas sensing element of the detector when the power is started is unstable, to ensure accurate detection of the detector, the preheating of the gas sensing element is important , during warm aerated prohibited detectors tested simultaneously detect pair keys, an alarm event is not responding. 2 LEDs and buzzer :
Normal state : red LED flashes once for about 5 seconds .
Fault Status : yellow fault indicator light ; buzzer sounds once every 2S .
Alarm status : red alarm indicator light , buzzer with frequency 2HZ tweet.
(3) self-test button:
Press the self-test button , the red indicator light , and accompanied by the buzzer , after the release of the self-test health , the detector automatically exit the self-test state.
4 when the combustible gas concentration in air reaches a threshold value, the detector and the trend of the concentration of gas logical judgment , when it is confirmed to be true gas leakage ( this process to maintain the 3-5S) , the red warning light detector immediately light and buzzer , while external passive contact signal output relay .
Three . Failure Analysis and Troubleshooting
Failure Analysis and Troubleshooting below:
1 indicator does not light : no power supply or power cord may not connected , please check the power supply and wiring.
(2) No output linkage : Check the jumper settings are correct , or network cable is not connected , check the jumper settings and linkage output lines.
3 Fault lights : the failure may be caused by gas sensor , replace the gas sensor .
Four . Maintenance and repair
1 Avoid heavy use of hair gel, mousse , pesticides, paint , alcohol , thinners and other items in the vicinity of the detector , so as not to affect the normal monitoring of the sensor ;
2 In the event of failure , please do not dismantle the detector for maintenance, users may notify the Company or the Company in the local offices, we will handle for you as soon as possible .
3 . Detector test once every six months .
4 prohibit the use of lighter detector test , to avoid affecting the gas sensor life.
5 . Detector at work a little heat is normal.
6 Do not arbitrarily cut off the detector power .
