Product Description

Combustible gas toxic gas H2S gas detector is modular designed, replaceable sensors and other modules. Automatic reminder when the sensor's lifespan expires, no calibration or maintenance required, data storage records can be checked, infrared remote control operation to avoid exposure to toxic and harmful gases

1. Display:

1. Field screen display: The field screen displays the concentration value detected by the current sensor in real-time;

2. Sound and light alarm: Three different frequencies of sound correspond to different working conditions;

3. LED: Three different colors of LED display the current status, green - normal, yellow - fault, red - alarm;

4. Infrared remote control: no need to open the cover, more convenient.

Function Description:

1. Main Function Overview:  Three way relay, multiple communication methods, sound and light alarm, alarm recording, time display, infrared remote control

2. Interactive Function:

1) Infrared remote control: No need to open the cover operation, address, alarm value, calibration value, test value support digital key input;

2) Time: Real time display with an error within 30 seconds;

3) Relay: Three way (220V, 5A) normally open relay output, high-power devices can be externally extended with intermediate relays;

3. Alarm record:

1) Record the time when the alarm occurred;

2) Record the concentration value at the time of the alarm occurrence;

3) Can cyclically store 40 alarm records; When not entered into the query, only the alarm values and alarm times that occurred in the recent time are displayed.

3. Overview of the advantages of Yao'an combustible gas alarm:

1) Flexible communication methods with added LoRa and WIFI wireless transmission;

2) Upgraded to IP67 for dust and water resistance;

3) 40 alarm records are stored in a loop;

4) Infrared remote control operation (without opening the cover);

5) Three relay normally open output;

6) The detection data is more stable and accurate, and the sound and light alarm decibels are higher.

4. Technical parameters:

1. Equipment parameter description:

1) Power supply: DC24V， Support dual bus; Power: Toxic -3W, Flammable -4W.

2) Working temperature and humidity: Temperature range: -40~70 ℃, humidity range: ≤ 90% RH.

3) Parameters:  Unit:% VOL,% LEL, umol/mol, mg/m3, ug/m3 (umo/mol and mg/m3 can be converted); Accuracy: 1, 0.1, 0.01; Gas range: can be selected according to customer requirements.

4) Implementation standard: GB15322.1-2003 2. Settings:

1) Internal settings: Gas type, gas unit, gas range, sensor range can be set; 2) Address setting: The address value can be any value between 1-255; 3) Alarm settings: switchable alarm types, set low and high limit values; 4) Time setting: Set the current time to better record operating conditions.

3. Zeroing, calibration, and testing:

1) Zeroing: Enter the zeroing interface to perform zeroing, which is easy and simple to operate;

2) Calibration: Upon entering the calibration interface, you can use the up and down keys to fine tune the calibration values, or enter numerical values using the numeric keypad;

3) Testing (entering the testing interface):

① 0 value (i.e. 4mA);

② Select the range and conduct tests at 0.2, 0.4, 0.6, 0.8, and 1x;

③ Adjust the current value by pressing the up and down keys for fine adjustment, or by typing numerical values on the numeric keypad to improve the linearity of 4-20mA.
