LC103-DB Open-Face Industrial Weatherproof Hotline Phone (Analog/SIP/4G LTE)
Reliable Emergency Communication for Industrial Facilities | Analog · SIP/VoIP · 4G LTE | IP67 · NEMA 4X equivalent · IK10 · CE · FCC · RoHS · ISO 9001 | 2-Year Warranty
The LC103-DB Series is a heavy-duty, open-face industrial hotline phone designed for instant emergency communication in steel plants, mining, and large warehouse terminals. Unlike standard models, its no-door design ensures immediate access to communication in critical situations, even when wearing industrial gloves.
Built with a corrosion-resistant aluminum alloy enclosure and IP67-rated environmental protection (NEMA 4X equivalent), this phone is engineered for the harshest conditions—extreme temperatures, high humidity, dust, and vibration. It features a vandal-resistant armored handset to prevent damage in high-traffic or unmonitored areas.
The LC103-DB Open-Face Industrial Weatherproof Hotline Phone (Analog/SIP/4G LTE) provides:
• One, Two or Three programmable hotline buttons for immediate connection to predefined numbers
• Clear full-duplex two-way communication for loud industrial environments
• High-visibility emergency interface for fast operation under stress
• Reliable voice transmission even in noisy production areas
