Household combustible gas detectors are professional instruments for detecting the concentration of gas leaks in home kitchens. In recent years, with the improvement of relevant policies and people’s safety awareness, household gas alarms have become one of the security products chosen by many residents.
However, during the installation and use process, people will encounter various problems, resulting in the wrong installation position of the alarm, incorrect use methods, improper maintenance and other problems. Today we will explain to you the common technical problems and solutions during the use of household combustible gas detectors to ensure that everyone has a more comprehensive understanding and use of the instrument.
What is the power of household combustible gas detectors?
The power consumption of household gas alarms is about 1~2W. In life, the equivalent of one kilowatt per hour is one degree of electricity, which also means that an electrical appliance with a power of one kilowatt will consume one degree of electricity after running for one hour. If the electrical appliance runs for 15 hours, the power consumption is 15 degrees, that is, fifteen kilowatt-hours.
What is the maximum current that passes through the relay of a household combustible gas detector?
When the JT-HD2000 series household gas alarm of Chicheng Electric drives 220V fans and other equipment, the maximum current that passes through is about 1A~1.2A.
What does the passive output of the relay of a household combustible gas detector mean?
The passive output of the relay is equivalent to a switch quantity, which is generally used to be connected in series to the customer’s electrical equipment. When the instrument does not alarm, the switch is disconnected, and when the instrument alarms, the switch is closed. Such as external fans, etc.
What does the active output of the relay of a household combustible gas detector mean?
The active output of the relay refers to a certain energy output function (such as outputting 220V power supply), which is generally used to directly control the customer’s electrical equipment. When the instrument does not alarm, there is no voltage output. When the instrument alarms, it outputs 220V power supply to control the operation of external equipment.

When the instrument does not alarm, there is no voltage output. When the instrument alarms, it outputs 220V power to control the operation of external devices.
Can the conventional configuration of Chicheng Electric JT-HD3000BLE home alarm be connected to Bluetooth gas meters from other manufacturers?
It cannot be directly connected. Chicheng Electric JT-HD3000 home alarm can be directly connected to the Bluetooth solenoid valve produced by the company. If there is a need to connect with gas meters from other manufacturers, it is necessary to provide protocols and prototypes for testing, and then release customized programs for production.
What is the reason why the household combustible gas detector keeps alarming?
When the household combustible gas detector alarms, the first thing to consider is gas leakage. At this time, the user can close the gas valve, open the window for ventilation immediately, and wait until the indoor gas concentration drops below the preset value of the instrument, the alarm will stop alarming.
Secondly, it may also be a false alarm. The false alarm of the household gas alarm is generally affected by five factors: cooking, steam and moisture, the flame of the stove is too high, the gas alarm is too close to the stove, and the gas alarm has exceeded its service life. At this time, the gas valve should be closed to find the cause.
Can the instrument continue to be used after its life expires?
The core component of a household combustible gas detector is the internal sensor, which has a certain service life. According to the national standard GB15322.2-2019, household gas alarms are equipped with a life reminder light.
If the instrument life light is on, it means that the instrument life has expired and should be replaced immediately. Under normal circumstances, the life of a household gas alarm is 3-5 years.
Can the power supply be unplugged directly after the household alarm alarms? How to eliminate the alarm sound?
After the household gas alarm alarms, the first consideration is gas leakage. At this time, the power supply cannot be plugged in or out to avoid electric sparks and explosion accidents. The window should be opened for ventilation, and the alarm will stop alarming when the indoor gas concentration drops below the preset value of the instrument.
If it can be determined that it is not a gas leak, such as instrument failure, the power supply can be unplugged and repaired by professionals.
In addition, the alarm with network function has a “remote mute” function. Users can click “remote mute” on the mobile phone APP to turn off the alarm sound.
Household combustible gas detectors are the last line of defense to protect household gas safety. Consumers should fully understand the instrument, master how to use and maintain the instrument, and protect household gas safety!
