LC101-KB-L Industrial Weatherproof Telephone with Flashing Beacon
Rugged Analog, SIP/VoIP or 4G LTE phone for harsh industrial, utility, transportation and remote-site communication.
The LC101-KB-L is a heavy-duty, all-weather industrial telephone designed for critical communication in harsh, noisy, and exposed environments. Fully enclosed in a corrosion-resistant, vandal-proof cast aluminum housing, it delivers reliable voice communication where conventional phones fail.
Who is it for?
Ideal for industrial plants, mining sites, petrochemical facilities, transportation hubs, tunnels, outdoor installations, and remote locations where equipment must withstand moisture, extreme temperatures, and high ambient noise.
The problem it solves
In harsh industrial environments, communication must work 24/7, regardless of weather, noise, or infrastructure limitations. The LC101-KB-L ensures clear, instantly visible, and always-available voice communication in safety-critical areas.
Why choose LC101-KB-L?
Designed for extreme heat, cold, moisture, and dust
High-visibility flashing beacon for incoming call alerts
Optimized for high-noise industrial environments
Proven long-term reliability with MTBF 50,000–65,000 hours (5.7 - 7.4 years of continuous 24/7 operation)
Flexible connectivity to match any infrastructure
Connection Technologies
Available in three versions to suit your deployment:
Analog – Standard two-wire analogue line, line-powered
SIP (VoIP) – IP-based communication via SIP, powered by PoE or external supply
4G LTE – Cellular communication using a local SIM card, no wired infrastructure required
Which version should I choose?
- Analog — for existing phone lines, legacy PBX systems, and line-powered industrial installations.
- SIP/VoIP — for IP networks, PoE infrastructure, SIP PBX systems, and remote configuration.
No landline or local network? Choose the 4G LTE version. Works with a local SIM card. Suitable for remote and hard-to-wire sites. Ideal for utilities, gates, pump stations, construction areas and outdoor service points. Antenna and power supply included with the 4G option
