Industrial Explosion Proof Telephone

 

 

The SC-EP01 Industrial Explosion Proof Telephone is designed for reliable communication in hazardous industrial environments such as oil and gas facilities, chemical plants, steel mills, mines, power plants, tunnels, highways, and other high-risk working areas.

Built with a heavy-duty aluminum alloy enclosure, the telephone provides IP67 protection against water and dust and is designed according to ATEX and IECEx explosion-proof requirements. The product carries an explosion-proof marking of Ex db ib IIC T6 Gb / Ex tb IIIC T80℃ Db, making it suitable for industrial locations where flammable gases or combustible dust may be present.

The SC-EP01 supports SIP/VoIP, analog, and direct fiber optic communication, allowing it to work with different industrial communication infrastructures. It also complies with CE, RoHS, and ISO 9001:2008 requirements.

An industrial explosion proof telephone is a specialized communication device used where ordinary telephones may not be suitable because of explosive gases, vapors, combustible dust, or demanding environmental conditions.

These telephones are commonly installed in oil and gas plants, petrochemical facilities, mining operations, offshore facilities, power stations, and industrial production areas where reliable voice communication is required.

 

 

 

1. The explosion-proof industrial telephone uses a durable aluminum alloy enclosure with an IP67 protection rating, helping protect internal components against water, dust, moisture, and harsh environmental conditions.
2. Supports standard SIP/VoIP protocols, 36–48V PBX analog systems, and direct fiber optic connections for different industrial communication requirements.
3. Optional accessories include an LED warning light and a 30W SIP loudspeaker for visual alarms, incoming call indication, and targeted announcements.
4. A predefined hotline number can be stored for one-touch speed dialing. The telephone also supports one-touch group calling without requiring additional server support.
5. Supports configurable ring detection and caller ID broadcasting. The number of rings can be set before automatic connection or announcement.
6. An optional LED warning light flashes during incoming calls to reduce the risk of missed calls in noisy industrial environments.
7. A dedicated intercom button supports broadcast and talkback functions. The telephone is equipped with a stainless steel keypad and stainless steel handset cable.
8. A heavy-duty stainless steel latch keeps the protective cover securely closed when the telephone is not in use, helping reduce exposure of internal components to the surrounding environment.

In hazardous industrial areas, communication equipment must remain available without introducing unnecessary ignition risks.

Explosion-proof communication equipment is used to:

• Provide communication in areas containing flammable gases or combustible dust
• Reduce ignition risks caused by electrical equipment
• Maintain communication between field personnel and control rooms
• Support emergency calling and operational coordination
• Provide reliable voice communication in noisy industrial locations

For projects in classified hazardous areas, the required explosion-proof marking and certification should be matched to the actual site conditions before installation.

 

 

 

Network Supports SIP V1 and SIP V2 protocols Supports backup server Supports proxy server and peer-to-peer connection modes Supports fixed IP / DHCP / PPPoE dialing Supports TFTP / DHCP / PPPoE client Supports Telnet / HTTP / HTTPS services

Audio Supports wideband HD codecs including L16G and G.722. Supports compression codecs including G.711a/u, G.726, G.729a/b, G.723, and others. Supports multiple audio functions including: VAD, Voice Activity Detection CNG, Comfort Noise Generation AJB, Automatic Jitter Buffer AEC, Acoustic Echo Cancellation AGC, Automatic Gain Control These functions help improve voice clarity and stability in industrial environments where high background noise may affect communication.

The SC-EP01 is intended for fixed communication points in hazardous and heavy industrial environments, including:

• Oil and gas fields
• Oil refineries
• Chemical and petrochemical plants
• Mining operations
• Steel mills
• Power plants
• Offshore facilities
• Industrial tunnels
• Heavy manufacturing areas

In these environments, the telephone can be used for routine operational communication, emergency calling, control-room contact, or integration with an industrial announcement system.

 

For projects that require both voice communication and local warning functions, the SC-EP01 can be configured with an LED alarm light and 30W SIP loudspeaker.
The warning light can provide a visual indication of incoming calls, while the loudspeaker can be used for announcements or targeted broadcasting.
This configuration is particularly useful in noisy industrial areas where an ordinary telephone ringtone may not be sufficient.
