SIP Emergency Handsfree Explosion Proof Telephone JWBT831P
Engineered for hazardous industrial zones, the JWBT831P is a SIP 2.0 explosion-proof emergency telephone featuring a rugged 304 brushed stainless-steel enclosure and a high-power loudspeaker for clear, full-duplex hands-free communication in noisy environments. Its prominent single-button design enables one-touch speed dialing even when wearing heavy safety gloves, while seamless compatibility with mainstream IP-PBX and industrial dispatch platforms makes it ideal for offshore platforms, petrochemical plants, mines, and ports.
SIP Emergency Handsfree Explosion Proof Telephone
Designed for rapid emergency calling in hazardous industrial zones, this handsfree explosion proof telephone combines an ATEX/IECEx-certified enclosure with SIP connectivity and true full-duplex audio. Its one-button, glove-friendly operation and high-volume speaker make it ideal for offshore platforms, chemical plants, and other high-noise, high-corrosion environments.
- Rugged 304 stainless-steel enclosure: Shock-resistant, anti-rust 304 brushed stainless steel with WF2 salt-spray protection for offshore and corrosive chemical sites.
- Standard SIP 2.0 integration: Works with mainstream IP-PBX, industrial dispatch systems, and VoIP servers; supports web management, remote firmware upgrades, and static/DHCP IP settings; dual SIP server redundancy helps keep communications online.
- Glove-friendly one-touch hands-free calling: Handset-free design with a large speed-dial button for instant control-room connection—even with heavy safety gloves; supports full-duplex, two-way handsfree audio.
- Noise reduction and high-volume audio: G.168 echo cancellation plus noise suppression and a high-power built-in speaker for clear speech in high-decibel industrial areas.
- Dual power input and surge protection: Supports IEEE 802.3af PoE and DC 12–24 V for flexible deployment; integrated network surge protection improves electrical reliability.
- Certified explosion-proof design: ATEX/IECEx certified for hazardous areas, with explosion-proof cable glands and a practical wall-mount layout for straightforward installation.
- Optional expansion features: External beacon/alarm light trigger support, SIP group broadcast paging, and remote status monitoring for improved site visibility and response.
