Explosion proof SIP IP Handsfree One Touch Speed Dial Emergency Telephone JWBT831P
JOIWO SIP IP explosion‑proof hands‑free emergency telephone is specially developed for flammable and explosive hazardous industrial locations. Adopt SIP 2.0 VoIP protocol, can integrate seamlessly with modern IP dispatch system and IP‑PBX. Handset‑free full‑duplex design, single physical button for one‑touch emergency calling, field workers wearing heavy safety gloves can establish communication with control room rapidly. Robust 304 stainless‑steel housing achieves WF2 salt‑spray resistance, suitable for offshore platform, seaside port and corrosive chemical workshops. Support PoE and DC12‑24V dual power supply, simplify on‑site cabling. Web‑UI remote management supports parameter configuration and firmware upgrade, convenient for large‑scale project deployment.
1. 304 Stainless‑Steel Heavy‑duty Housing: Brushed 304 stainless‑steel enclosure, shock‑resistant, anti‑rust, WF2 salt‑spray resistance, perfectly adapt to offshore seaside, heavy‑corrosion chemical workshops.
2. Standard SIP 2.0 VoIP Communication: Fully compatible with mainstream IP‑PBX, industrial dispatch intercom system, VoIP server. Support web browser remote configuration, firmware upgrade, static/DHCP IP setting, main‑backup SIP server auto‑switch for stable site communication.
3. One‑Button Emergency Speed‑dial, Glove‑friendly Hands‑free Operation: No keypad, no handset. Pre‑set SIP target number, press physical button to call control room instantly. Operable with heavy safety gloves, full‑duplex bidirectional audio, no need to hold any handset during conversation.
4. Optimized Industrial Audio Algorithm: Built‑in G.168 echo cancellation and noise reduction algorithm, suppress heavy factory background noise. High‑power built‑in speaker delivers clear audio under noisy industrial site.
