product description


The HA-818B 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.

This detector is AC type, DC type. After the alarm, a pair of relay passive contact signals can be output (normally open, normally closed, jumper setting), which is used to control ventilation equipment or provide normally open or normally closed alarm contacts for other equipment.

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

Installation Notes


1. The alarm should be installed at a position less than 30cm from the ceiling, more than 2cm from the ceiling and walls, and less than 8m from the kitchen utensils.
2. During installation, first fix the hanging plate, then insert the lead-out wire, and then screw the alarm into the base. As shown below



Precautions


1. The alarm should be installed in a position that is easy to observe and easy to check by air jet.
2. The alarm should be installed in the room where there is a gas appliance and there is a possibility of gas leakage. There may be no alarm for gas leakage in other rooms.
3. It is strictly forbidden to shake, drop, or shock the alarm during the installation process, otherwise the alarm will fail.
4. The installation position of the alarm must not face the oil and gas.
5. The alarm cannot be installed in a place with good ventilation or large air flow.
6. The alarm cannot be covered by other objects.
7. The alarm should not be installed near vibrating objects such as refrigerators and air conditioners.
