DC Powered Wire-In Combustible Gas Detector
Outline
Combustible gas detector ( hereinafter referred to as detectors ) uses advanced microprocessor technology with high quality catalytic combustion gas sensor was developed for the detection of combustible gases ( such as natural gas , liquefied petroleum gas , etc.), due to the combustible gas diffusion caused by fire , explosion , poisoning 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 factories , warehouses, room, family , hotels, apartments and other combustible gas leak needs to be a place of safety monitoring .
Features
High quality gas sensors , reliable , good consistency
Microprocessor intelligent algorithm automatically compensates for drift gas sensor
Catalytic combustion gas sensor is stable, long life and eliminate false alarms
Test Button - Test the alarm circuit alarm output
LED lights - Display alarm is working properly , the alarm state
Shell is made of fireproof ABS plastic , nice
Performance parameters :
I. Features
1 using catalytic combustion gas sensor , stable, sensitive response ;
2 small, easy to install , easy to use ;
3 microcontroller (MCU) intelligent judgment , stable performance.
Two Technical Specifications
1 Operating Voltage :. AC220V or DC12-DC28V
2 Power: Normal monitoring ≤ 1.5W, alarm status ≤ 3W.
3 Alarm sound : greater than 80dB.
4 alarm levels set : 8% LEL (4000ppm).
5 . Sensor life :3- 5 years
7 Operating environment: Temperature : -10 ℃ ~ +50 ℃, relative humidity ≤ 90%, non-condensing
8 Dimensions :. 120mm × 72mm × 42mm
9 shell materials and colors :. ABS ivory
Three . Use and operation
1 Preheat the power : After the probe is energized , it will issue a "beep " sound, while the green "POWER" indicator lights , which means that normal power ; then the yellow light starts flashing , which means that the detector into the warm-up phase , detector warm-up duration of approximately 30 seconds -60 seconds after the end of the warm-up , the detector goes off yellow light , and issued a " drip , drip " twice , which means that the detection probe into the normal working condition . 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 : green LED is lit , yellow, red light is off, the buzzer silent .
Fault Status : yellow fault LED is lit, sensor failure , the buzzer sounds (0.5S ON / 2S OFF).
Alarm status : red indicator light , buzzer shortness tweet (0.5S ON/0.5S OFF).
(3) self-test button:
Press the self-test button , LED light , and accompanied by the buzzer .
4 gas detection : the detector kept on the air environment for the collection , analysis and judgment , when the air in the combustible gas concentration reaches the alarm threshold , the MCU by the detector gas concentrations and gas diffusion trend for analysis, when it is confirmed to be true when gas leakage detector immediately lit red warning light and buzzer .
5 alarm handling : When the detector alarm, immediately open the windows so that the indoor air circulation, extinguish all sources of ignition , do not create a fire source , avoid all kinds of electrical switches , check the cause of the gas leak , and timely repair to professionals .
6 silencer : Under detector alarm status , click the self-test button , the detector can silencer ; under silencer state , the red LED flashes quickly , silencers state can be maintained 4 minutes , the time to quit on their own. Or click the mute button again to exit the mute state.
7 RESET: In alarm mode, press the self-test key, lasts about 5S, detectors to be reset.
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 when
Land offices, we will handle for you as soon as possible .
3 . Detector test ban lighters , to avoid affecting gas sensor life.
4 detectors at work a little heat is normal.
Five . Special Statement
Replace the sensor exceeds a timely manner when the product life ( years ) when . The Company does not assume warranty responsibility in one of the following occurs:
1 fails the requirements described in the installation, use product damage .
2 grid voltage is too high or because of changes to the machine with its own external power or self- open the case and cause damage.
3 due to damp , throw, touch, pressure , damage caused by smashing behavior .
4 Other reasons for the use of man-made damage caused by improper .
