What Are the Different Types of Walkie Talkie Accessories?

Explosion-proof walkie-talkies are walkie-talkies that can work in explosive gas environments. Unlike civilian walkie-talkies, explosion-proof walkie-talkies do not refer to walkie-talkies that can withstand explosions, but rather walkie-talkies that can work in explosive gas environments.

Explosion-proof walkie-talkie

Explosion-proof walkie-talkies are walkie-talkies that can work in explosive gas environments. Unlike civilian walkie-talkies, explosion-proof walkie-talkies do not refer to walkie-talkies that can withstand explosions, but rather walkie-talkies that can work in explosive gas environments.

Applicable to harsh environment, hazardous flammable gas or dust environment such as petrochemical, coal mine, chemical industry, thermal power, food processing and other industries. We know that walkie-talkies rely on

The appearance of explosion-proof walkie-talkies is not different from that of ordinary walkie-talkies, but the materials and physical characteristics used are very different from ordinary models.

1: Class (Explosive)

Class I: Volatile gasoline (and other petroleum products) / air mixtures

Class II: Dust / air mixture

Class III:

1. Do not replace batteries and other accessories in hazardous environments. Contact with sparks during disassembly may cause explosion or fire. Even if the product is certified by the explosion-proof testing agency, the accessory connector must not be exposed when used in a hazardous atmosphere. When the accessory connector is not needed, it should be covered with a dust cover.

2. Do not disassemble the products certified by the explosion-proof testing agency by any means. Modifying the intercom opportunity changes the original design structure of the intercom hardware. Only the original manufacturer of the product can make modifications in a production site certified by the explosion-proof testing agency. Unauthorized modification will invalidate this product's explosion-proof certification.

3. When the whole machine is charging, the power switch should be turned off. It is not allowed to perform call transmission operation at the same time when charging, so as to avoid accidental burning of components or batteries.

4. Do not short-circuit the two terminals of the battery "+" and "-".

5. When in use, do not pick up the antenna by hand, do not bend the antenna.

The explosion-proof logo is printed on the radio (see the figure below), indicating that the radio has passed explosion-proof certification. The explosion-proof mark nameplate indicates the hazardous environment level that the radio can use, the Motorola battery part number that must be used with it, the user manual number, and the temperature code. With explosion-proof models. This explosion-proof model has passed the American Explosion Protection Research Council (FM) explosion-proof certification. Explosion-proof grades are IS / I Safe Class , , Div1, Grp CDEFG and NI Class Div 2, Grp A, B

The temperature code of C and D is T3C. Among them, IS is intrinsically safe and NI is N. Explosion-proof radios must use explosion-proof batteries. Only when used strictly in accordance with the prescribed scope can safety be ensured. The explosion-proof mark must be affixed after inspection before the product is shipped from the manufacturer. It is absolutely forbidden to "upgrade" to an explosion-proof product and attach the explosion-proof mark at other locations.
