Install gas alarm works? Where is suitable for installation

Gas alarm works

Most people would ask to install gas alarm is useless, gas alarm at the core of the original parts for gas sensors, installed in place of gas leakage, when the concentration of gas in the air will be triggered more than set point detector alarm, and foreign send out sound and light alarm signal.

Gas alarm can protect the safety of life and property. In civil security engineering, used for household gas leak alarm, more so for the sake of the family safe, small make up suggest everyone to install gas alarm, safety is first

Gas alarm installed in what place

Suitable for installation: gas alarm is suitable for installation within the scope of the distance air radius of 1.5 meters, well ventilated place:

(1) liquefied petroleum gas (LPG) - is heavier than air, deposition in the lower, wireless gas detector should be installed in the lower part of the air. To install a wireless gas detector with the burner or horizontal distance of the valve shall not be greater than 3 m, installation height should be less than 0.3 m off the ground.

(2) the coal gas, natural gas, lighter than air, floating in the high places, wireless gas detector should be installed in the upper portion of the air. To install a wireless gas detector with the burner or horizontal distance of the valve shall not be greater than 6 m, installation height should be less than 0.3 m from the ceiling, and above shall not be located in burner.

Can´t install the location of the alarm: corner, enclosure, such as the location of the air to flow, easy by lampblack smoked a position directly.

Using the operating methods

On electricity preheating, wall-mounted gas alarm after electrify independently, have a "di", "POWER" indicator light green light at the same time, the normal electricity; And yellow lights began to shine, said the probe into the preheat phase, the probe´s preheating duration is about 30 seconds to 60 seconds, after the preheating, probe out yellow lights, at the same time issued a ", drops "two, said the probe into the normal testing working condition. Detector of gas sensitive element charging at the beginning is not very stable, in order to ensure the accurate detection of detector work, implementation is very important for gas sensitive element of the preheating, prohibited to gas detector test during preheating, detector at the same time no responses for the key processing, alarm events.

Light and buzzer:

Normal: green light is lit, yellow, red light is extinguished, buzzer silent.

Fault status: yellow failure indicator light, sensor failure, buzzer sing (0.5 S 2 S ON/OFF).

Shortness of alarm status: red indicator light, buzzer sing (0.5 S 0.5 S ON/OFF).

Self-checking button: press the introspection, LED light, accompanied by a buzzer.

Gas detection: independent wall-mounted gas alarm keeps air in the environment is used for acquisition, analysis, and judgment, when the concentration of combustible gas in the air to alarm threshold, by the detector in the MCU of the concentration of the gas and gas diffusion trend analysis, when confirmation is real gas leak detector light red alarm lamp and immediately start the buzzer.

Alarm processing: when independent wall-mounted gas alarm, immediately opened the window to make indoor air circulation, put out all fire, don´t make fire, avoid various electric switch, check the gas leak reason, and please professional repair in time.

Mute: in the condition of wall-mounted gas alarm alarm independently, click the self-check keys, deadened the noise of detector can be; Mute state, the red LED quickly ablaze, the mute state can maintain 4 minutes, time to quit on his own. Or click the mute button to exit the mute state again.

Reset: in the alarm state, press the introspection, lasts about 5 s, wall-mounted independent gas alarm is reset.
