Installation Notes

1、Recommended installation area.

It is recommended to install the alarm near the bedroom and living area, or where you think gas may leak. Detecting propane leakage should be installed within 30CM from the ground and within a radius of 1.5 meters from the gas source. Detecting methane should be installed at a distance from the ceiling. A suitable location within 30CM and within 1.5 meters of the half diameter of the gas source.

2、Installation Precautions

(1) Do not install outside the building, in the cupboard or other damp, wet, dusty, greasy places, such as kitchen, garage, oil, dust or household chemicals will damage the sensor head of the alarm, make the alarm Can not work normally.

(2) Do not install it in a place with no ventilation, such as the top of a vaulted ceiling or a pointed roof. If the carbon monoxide alarm is installed too high, the alarm cannot be issued in time.

(3) Do not install in places where the temperature is lower than 0°C or higher than 50°C, including rooms, attics, corridors and garages. Extreme temperatures will affect the sensitivity of carbon monoxide gas alarms.

(4) Do not block the alarm vents. Install the alarm in a place where it will not be blocked by curtains, furniture or other objects.

(5) Do not install the alarm in a place too close to the burning appliance, which may cause frequent alarms and cause noise pollution.

(6) Do not install near doors and windows leading to the outdoors, near fresh air vents or any other well-ventilated place. Rapidly circulating air from fans or fresh air from outdoors can affect the response of the alarm.。

3、Install

The alarm can be installed on the ceiling or on the wall. After selecting the installation location, draw the mounting holes on the mounting bracket, punch holes on the drawn marks, insert the rubber plugs into the holes, and install them with self-tapping screws. The bracket is installed and fixed. If it is not convenient to punch and fix it, it can also be fixed with adhesive.。

Align the hook groove on the rear panel of the alarm with the buckle on the mounting base, fasten the alarm and the mounting base from top to bottom, and the installation is complete.。

4、Wiring Instructions

In the above figure, there are two control outputs, one is used to connect the exhaust fan, and the other is used to cut off the air source.

The control output port connected to the exhaust fan can be connected to an exhaust fan with a maximum specification of 220V/1A.

Connecting to the power port of the solenoid valve can connect to a shut-off solenoid valve with a maximum DC12/1.5A specification.

The power adapter interface is used to supply power to the device, and only supports the input and output of a DC12V power adapter.

Instructions

1、Instructions for use

After the alarm is powered on, the buzzer prompts "beep", the green light, yellow light and red light flash alternately and cyclically, the LCD screen decreases from 180 to 0, the preheating is over, the alarm enters the fault detection state, and enters the normal state after the detection is normal. Detection status. The green indicator light is always on. When the gas concentration value in the air is greater than 50PPM or the gas concentration value is greater than 3% LEL, the LCD backlight will light up, and the LCD screen will display the real-time concentration value of the detected gas in the environment.

When the measured gas concentration in the environment reaches the alarm setting value, the alarm will send out a sound and light alarm indication, and turn on the control output (DC12V pulse output, the relay normally open contact is closed), the red indicator light indicates the alarm state, when an alarm occurs At the same time, the red indicator light flashes, and at the same time, the buzzer emits “Di Di, Di Di, Di Di, Di Di, Di Di, Di Di, and beeps 5 times, with a cycle of 6 seconds, until the concentration of carbon monoxide and gas decreases to the set value for releasing the alarm. In the following, the alarm information is sent to the user platform and mobile phone remotely when an alarm occurs.

The yellow indicator light indicates the fault state. When the sensor fails, the yellow indicator light is always on, and the buzzer prompts "Di Di Di" and the LCD screen displays the low fault code "Gas open and short fault Er2". And send the fault information to the WeChat applet to notify the user.

When the service life of the sensor expires, the yellow light flashes, and the LCD screen displays "En2", which means that the service life of the gas sensor has expired. And send the fault information to the WeChat applet to notify the user.。

2、Test the muting button method

Press the "TEST" button to test the product, the green indicator light is always on, the red indicator light flashes 4 times, the buzzer prompts "Di, Di, Di" to send the test information to the WeChat applet for display, and the LCD backlight lights up at the same time After 15 seconds, the LCD screen displays the current concentration value. Detect whether the sensor, indicator light, and LCD display are normal. In the case of an alarm, press and hold the test button for 5 seconds to eliminate the alarm buzzer prompt and output signal, and the alarm will not perform the detection function. After about 10 minutes, To restore the detection and alarm function, press the test button to power on for 6 seconds before the power is turned on, and the Chinese/English alarm standard will be switched.

Gas Safety Knowledge

1、Introduction to Gas

Gas is divided into natural gas and liquefied gas. Gas itself is not harmful to health. It is a non-carcinogen and will not affect the human body. Therefore, no agency has imposed a limit on the exposure concentration. However, for high-concentration gas, because it will replace the oxygen in the air, it will cause an oxygen-deficient environment, which will endanger human health and even life. Mixing with air can form an explosive mixture, which can cause an explosion in case of open fire and high heat. Its vapor is heavier than air, and can spread to a considerable distance at a lower place, and it will cause flashback when it encounters a fire source. In case of high heat, the internal pressure of the container increases, and there is a risk of cracking and explosion.

Note: If the gas concentration exceeds 5% VOL in a closed space, it will cause an explosion hazard in case of an open flame.

2、Introduction to gas

Always open indoor doors and windows to keep indoor air circulation, install combustible gas alarms at appropriate locations, monitor the concentration of combustible gases in real time, and remind people to leave the dangerous area when the alarm occurs to prevent combustible gas explosion or poisoning.

3、Police handling

When the gas concentration in the air environment exceeds the set concentration value of the alarm, the alarm will send out an alarm buzzer prompt and an indicator light alarm signal. At this time, the following measures should be taken: immediately close the valve channel, open the doors and windows to keep the indoor air circulating, Leave the dangerous area, if the alarm continues to alarm, please notify relevant departments or professionals to deal with it. If the inspection is a false alarm, the user should check whether the installation location of the alarm is appropriate.

4、Alarm condition of alarm

National standard GB15322.2-2019		European standard EN50291
Alarm concentration value	Response Time	Alarm concentration value	Response Time

150PPM	Alarm within 60 seconds	50PPM	60 minutes after 90 minutes before alarm
300PPM	Alarm within 30 seconds	100PPM	10 minutes after 40 minutes before the alarm
		300PPM	3 minutes before the alarm
