Gas Alarm Installation Instructions

1. Alarm installation location: within 1.5 meters from the air source radius, well ventilated: (1) liquefied gas is heavier than air and installed at about 0.3 meters from the ground. (2) Natural gas, city gas, carbon monoxide, etc. are lighter than air and are installed about 0.3 meters from the ceiling.

2. The location where the alarm cannot be installed: the location where the air is not easy to circulate in the corner, the cabinet, etc .;

3. The gas alarm uses a wide range of voltages. Commonly, it is a 220V civilian voltage product. Generally, the voltage of 12V is relatively rare. The power supply method uses a telephone line interface. It is suitable for users with higher safety requirements. It is installed in the bedroom. Small and practical!

Application production and sales of the alarm you want in your heart 1. Power light: green light, lights up after power-on, and goes off when the alarm occurs.

Alarm light: red light, lights up when the alarm, and goes off when the alarm is stopped.

2. After turning on the power, after the green light is on or flashing for 3 minutes, the alarm starts to work normally.

3. When the detected gas reaches the alarm point, the alarm starts to alarm, the green light goes out, the alarm light turns on, and the buzzer emits an alarm sound of "B, B, B ...". When the concentration of the detected gas drops below the alarm point When the alarm stops, the alarm will stop. (Carbon monoxide alarm has delay function)

4. If the manual detection function is added, when the button is pressed, the green light goes out, the alarm light turns on, and the buzzer emits an alarm sound of "B, B, B ...".

5. If the combined exhaust fan function is added, when the alarm alarms, the connected exhaust fan will start to automatically remove harmful gases.

6. If the function of connecting manipulator or solenoid valve is added, when the alarm alarms, the connected manipulator or solenoid valve will automatically close the gas valve, thereby cutting off the harmful gas source.

7. If the networking function is added, the management center or control center receives the normally open and normally closed (NO, NC) signals at the same time when the alarm alarms. (For the wireless function added, the alarm host will receive the wireless signal for 2-3 seconds)

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 flammable gas concentration in the environment reaches the set threshold, it can send out sound and light alarm signals, and can output relay passive contact signals.

When the surrounding environment flammable gas concentration drops below the response threshold, the detector in the alarm state will automatically return to the normal working state.
