Bus gas leak detectors affordable aluminum factory direct probe gas leak alarm vehicle for a variety of oil to gas cars, which consists of a controller and a detector composed of two parts, a gas leak detector detects the signal is passed to the alarm control panel, control panel audible alarm in order to take measures to prevent accidents. This product is imported from US chip-based movement models, while adding automatic sensor drift compensation function to prevent false positives and false negatives, this alarm device with high sensitivity and high stability. Is suitable for gas safety adapt high-quality products, the concentration of natural gas leak once the car reaches the set alarm value, the alarm device will promptly audible alarm signal to remind you to take prompt and effective measures; turn off gas supply to exclude car danger; effectively prevent the occurrence of spontaneous combustion cars, explosions, asphyxiation, death and other serious accidents. Product Scheme 1. The main parameters for gas: Natural gas alarm settings: 1.0-25% LEL (500-12500PPM) Input Power: DC12V / 300mA Static power consumption: ≤0.5W alarm Power: ≤3W Response time: <30 seconds alarm sounds:> 85 db gas sensor (from 1M): The life of two years linkage function: can be equipped with the linkage manipulator Specifications A: YK-828 / CB with two probes Weight: 560g with robot weight: 945g Specification B: YK-828 / CB with three probes Weight: 690g with robot weight: 1075g controller Dimensions: 104 * 66 * 32mm Control Panel Size: 78 * 45 * 23mm sensor size: 65 * 39 * 32mm robot size: 72 * 63mm Box size: 203 * 140 * 75mm 2. The basic function of the vehicle when the gas alarm gas concentration reaches the set value in response to the concentration of the surrounding environment, can emit sound and light alarm signal. When the detector is in alarm state, the indoor environment to respond to the concentration of gas concentration drops below the set value, can be automatically restored to the normal monitoring state. The alarm device by the display panel, alarm control (containing all the way to the detector), detectors, three parts (with automatic shut-off valve function alarm emergency shut-off valve comprises a valve, close the control buttons are displayed in the alarm control panel The two-way alarm zone, a detector to be increased three-way alarm zone, must add a detector). Alarm controller contains all the way to the controller. Peripheral connectors have a ten-core output jack, go to the control panel wiring harness connection. There are three core a jack to connect the detector, there is a two-wire output jack, connect the robot. There switch control, were marked with lights indication. ① Press the "test button" alarm alarm, normally closed output signal, the robot starts to close the valve shut-off valve. Alarm does not act, the robot does not move. ② control the display panel has a power switch, red, green, yellow status indicator lights and built-emitters. ③ Press the "test button" alarm alarm, such as when the valve is closed, then open the valve so that the robot starts to make the cylinder valve is turned on immediately. If the valve is turned on, then make the robot start to close the valve, so that the cylinder valve is closed immediately. Valve light yellow indication. ④ power is turned on, the green light is blinking, about 1-3 minutes, the controller uttered a prompt indicating detector is working properly, in the monitoring of state; ⑤ indicator flashes red and green flashing probe zone, accompanied by the sound of a buzzer, indicating that the probe in alarm. ⑥ When the green and yellow flashing alternately, says probe fails, you should contact the service agent or return to factory warranty. Second, the installation instructions 1. Alarm controller should be installed in the place you want to test a gas leak (such as the trunk), the trunk should be installed at the outlet from the gas bottle and note the location of the nearest installed in the upper position. 2. The display panel installed in the car dashboard proper position, connected by a harness and alarm controller. 3. Detectors installed in the place you want to test a gas leak (engine compartment). Should be installed in the engine compartment above the position away from heat sources. And the control panel is connected by a harness. 4. Closures have connected device is mounted on the cylinder shut-off valve, and alarm controller. 5. Display panel outlet red, black two, access to the selected input source. Red connected to the positive, black to the negative. 6. Parking is off alarm power, when installed by the user to decide. 7. Reference Manual Instructions alarm wiring. Note: 1. Control the display panel should be installed in a position easily observed. 2. Detectors should be installed in readily accessible for inspection, where a gas leak. 3. Do not use ultra-high concentration of gas test the machine, so as not to damage the life of the alarm, and potentially harmful to human health. 4. Never install process, vibration, drop, shock this product, otherwise it will fail. 5. Detectors should not be installed in a well-ventilated or air-large at 6. He can not be obscured object detector. 7. There are two gas detectors should be prohibited immediately alarm isolation and the validity of the alcohol contact. In order to prevent damage to the sensor. Third, the use a. Debugging a. In accordance with the requirements of the installation will alarm installation fixed. 2. Turn on the switch, turn on the alarm of power, when the power indicator is blinking, the alarm enters warm-up state. At this time no gas detection alarm function, about 1-3 minutes later, the alarm into the normal monitoring status. 3. When the car environment as natural gas leak concentration reaches the alarm, the alarm device enters an alarm condition. In this case the control panel display indicates the zone flashing green and red lights, while an alarm sounds. (With a closing function of the alarm after alarm quickly launch emergency shut-off valve, and automatically close the cylinder valve). 4. When the ambient concentration of combustible gas concentration falls below the alarm, the alarm indicator stops flashing and alarm devices to detect the state of recovery. (Alarm function with a closed press the test button the display panel, so open the cylinder valve closed, open the shut-off valve will switch back to the "test" state). b. Emergency Treatment 1. When each zone indicator and red alarm indicator lights accompanied by an alarm sounds, indicating the presence of high concentrations of gas leaks exist in the environment. Discoverer of the following procedures should be checked immediately. 2. Close all gas source (gas cylinder switches, etc.). 3. Now open the door, window air convection, natural exhaust. 4. At this non-ignition and open other electrical products. 5. If someone headache, nausea, malaise, irritability, or other symptoms of shock, first aid should be sent to hospital. 6. After the gas dissipated, a search cause of the accident, and timely treatment. 7. If you can not rule out the cause of the accident, please come to rule out a gas leak fault professionals. 8. Belong to the alarm quality reasons, please contact the supplier to be checked. 9. Belong to a gas leak, please contact the relevant authorities, to check for possible leaks in the gas source 10. Note: paints, cosmetics, alcohol and other chemical odors may cause the detector alarm, should make these items away from the detector, reducing false positives.
