Explosion-proof-speaker5WExplosion-proof-speaker-user-manual
Explosion-proof loudspeaker 360 ° no dead angle loudspeaker, suitable for installation in explosive gas environment place containing Class IIC, T5 temperature group, used for live broadcasting and sound reinforcement.The speaker is used in conjunction with various power amplifier devices, and is used together in the paging intecom system, with a call alarm function.Explosion-proof loudspeaker is an outdoor loudspeaker specially used in hazardous areas. It can be used in an explosive atmosphere or in an explosive environment. It is often used in offshore paga systems, natural gas and oil fields, and can help you build a safe paging system.
ATEX, taken from the French abbreviation of "ATmospheres EXplosibles", means "explosive environment".
The ATEX Directive requires the design and manufacture of explosion-proof equipment and protection systems to reduce accidents and limit serious explosions. Applies to:
(1) The new "equipment" is used for electrical components, instruments and machinery in explosive atmospheres.
(2) Provide protection and control systems with unavoidable explosions and other explosive atmosphere explosion vents, suppression systems, etc.
The ATEX directive was cited in the laws of EU member states in March 1996, and ATEX has been enforced since July 1, 2003. All products put on the market and put into use for potentially explosive atmospheres must comply with the ATEX manufacturer's directives (excluding products other than those specified in the directives).
The professional explosion-proof horn meets the certification requirements of the explosion-proof certification ATEX, which is very suitable for explosive environments and suitable for use in flammable gas environments. Professional-level explosion-proof speakers meet the requirements of industrial outdoor use, and the waterproof level reaches ip66. It can be used normally at an ambient temperature of -40 degrees Celsius to +55 degrees Celsius. II 2GD Ex db eb mb IIC T5 Gb; II 2D Ex tb IIIC T100℃ Db.
The application field of explosion-proof speakers is very wide. In general, explosion-proof speakers are mainly used in the following places:
1. Workshops that easily produce dangerous gases (laboratories, chemical plants, natural gas sites)
2. Workshops with a lot of dust (clean workshops, coal mines, chemical plants)
3. Workshops with dangerous liquids (petrochemical industry)
4. Workshops in other flammable and explosive industries such as papermaking and textiles
