product description


The HA-818X combustible gas detector (hereinafter referred to as the detector) is a highly stable semiconductor sensor, which has the characteristics of high stability and small sensitivity drift. It is used for indoor detection of flammable gas leakage to prevent the harm caused by gas leakage. It is widely used in households, hotels, apartments and other places where flammable gas is present for safety monitoring. Can detect natural gas, liquefied petroleum gas, artificial gas.

When the detector detects a flammable gas leak and reaches the alarm concentration set by the detector, the detector's red LED flashes and emits an alarm sound.

Installation Precautions



1. First determine that the gas to be detected is heavier or lighter than air, and gas heavier than air: liquefied petroleum gas, etc .; lighter than air: natural gas, artificial gas, biogas, etc.

2. Install the detector in a suitable place according to the weight of the gas.

When detecting gas heavier than air: install it 0.3-1.0 meters above the ground and within 1.5 meters from the air source; when detecting gas heavier than air: install it 0.3-1.0 meters below the ceiling and within 1.5 meters from the air source ( (See the figure below for details).

3. Fix the detector bracket to the wall with mounting screws and hang the detector.

4. When installing at home, you should also pay attention that the installation location should not be too close to the gas stove to avoid the detector being baked by the flame of the stove; it should not be installed in a place with large oil fume to prevent false alarms or the detector's air inlet Poor air intake affects the sensitivity of the detector; nor can it be installed in exhaust fans, near doors and windows and in places with large water vapor in the bathroom.

5. Make correct wiring as shown in the figure. All wiring installations must comply with national and local effective regulations and standards. Improper connection will cause the alarm to not work properly in the event of a gas leak.

Instructions

1. Detector wiring instructions

1.1 Check the label on the back of the product before wiring to determine the product's working voltage and output function. The DC working voltage is DC9-24V; the AC working voltage is 220V. A 5PIN terminal cable is provided in the box.

AC type: The red line is connected to the AC power line, and the black line is connected to the AC power neutral line. DC type: The red wire is connected to the positive pole of the DC power supply, and the black wire is connected to the negative pole of the DC power supply.

1.2, the connection of the relay output line:

White line: common terminal for relay output

Yellow line: normally closed end for relay output

Orange line: normally open for relay output

1.3, the connection of the solenoid valve output line:

Orange line: positive for signal output of solenoid valve

Yellow line: negative for signal output of solenoid valve

Note: The relay output and solenoid valve output functions, the detector cannot have both output functions at the same time, please check the label on the back of the product when wiring, determine the output function, and then wire according to the corresponding function.

Function description

2.1. Turn on the power of the detector. The green LED of the power indicator is always on, and the buzzer “嘀”, the circuit enters the preheating state. At this time, the red LED and the yellow LED flash alternately, and stop after flashing for about three minutes, indicating detection. Device into normal working state. Gas testing is prohibited during warm-up.

2.2. When the detector detects a flammable gas leak and reaches the alarm concentration, the alarm indicator red LED flashes, and at the same time the buzzer emits a "嘀-嘀" alarm sound. The relay with auxiliary output function or the pulse signal output from the solenoid valve output closes the solenoid valve.

2.3 When the sensor inside the detector fails, the yellow LED of the detector stays on and the buzzer keeps beeping. Disconnect the power and contact your local dealer for repair. Do not disassemble the detector without permission to avoid the danger of electric shock.

3. Product testing

3.1. This product has a self-test button, which can be used to detect whether the LED and buzzer of the detector can work normally. When the self-test button is pressed, the red LED and yellow LED of the detector will flash alternately, and the buzzer will alarm sound.

3.2 It is forbidden to use a lighter to directly test the gas convection window of the detector, otherwise the sensor inside the detector will be damaged. If testing is needed, the gas of the lighter can be put into an empty plastic mineral water bottle, and then the mouth of the mineral water bottle is aligned with the gas convection window of the detector to deflate.
