One of the best gas alarm manufacturers

Buy household gas alarm everyone routinely listened to the introduction made by the seller, oneself buy back is often a bad product, get back in, have been used for, the seller does not agree, so that in the long run for our life brought a lot of trouble, directly affect our normal use.

Small make up detailed to introduce the function and the usage of household gas alarm, in order to facilitate everybody when buy discern between true and false.

An overview of the

GA502Q -d wall-mounted gas alarm independently advanced microprocessor technology combined with the best quality of catalytic combustion type gas sensor development, used to detect combustible gases (such as natural gas, liquefied petroleum gas), for because of the spread of the combustible gas fire, explosion, poisoning accident can be carried out safety monitoring and early warning, the detector with high sensitivity, good reliability and resistance to cigarettes, alcohol, and automatic temperature compensation function, widely used in factories, warehouses, engine room, home, hotel, apartment and so on need for safety monitoring of combustible gas leakage.

The performance characteristics of

By catalytic combustion type gas sensitive element, the work is stable and sensitive response.

The microprocessor intelligent algorithm automatically compensate gas sensor drift.

Catalytic combustion type gas sensors work stability, long service life, put an end to false alarms.

Test button - test alarm circuit, alarm output.

The normal work and alarm status leds - display alarm.

The shell adopts fireproof ABS engineering plastics, the beauty is generous.

Small volume, simple installation, easy to use.

Microprocessor (MCU) intelligent judgment, stable performance.

Product parameters

Working voltage: AC220V or DC12 - DC28V.

Power consumption: normal monitoring acuities were 1.5 W, 3 W or less alarm state.

The alarm sound: greater than 80 db.

Set alarm concentration: 8% LEL (4000 PPM).

Sensor life: 3 to 5 years.

Using the environment: the temperature: - 10 ℃ to + 50 ℃, relative humidity of 90% or less, don´t gel.

Shape size: 120 mm * 72 mm * 42 mm.

Shell materials and colors: ABS ivory white.

Use and operation

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.

Maintenance and repair

Please avoid near the wall independent gas alarm detector use hair gel, mousse, pesticide, paint, alcohol, the article such as thinner, so as not to affect the normal monitoring of the sensor.

If failure happens, please don´t remove the detector secretly maintenance, users will be able to inform the company or the company is located in the local office, we will for you as soon as possible.

Independent wall-mounted gas alarm banning the use of lighter testing, so as to avoid affecting the service life of gas sensitive element.

Independent wall-mounted gas alarm is a bit hot at work belongs to the normal phenomenon.
