LC103-DB Open-Face Industrial Weatherproof Hotline Phone
Analog · SIP/VoIP · 4G LTE | IP66/IP67 · NEMA 4X Equivalent · IK10 | 2- or 3-Button Direct Call
The LC103-DB Open-Face Industrial Weatherproof Hotline Phone is a rugged fixed communication terminal designed for industrial sites where users need immediate access to predefined contacts without dialing a full telephone number.
Its open-face design keeps the handset and direct-call buttons immediately accessible, while the die-cast aluminum enclosure, armored handset cord, noise-cancelling microphone, and corrosion-resistant hardware make the LC103-DB suitable for demanding indoor and outdoor locations.
The phone is available with two or three programmable direct-call buttons, allowing each button to connect to a predefined destination such as a control room, maintenance team, security desk, dispatcher, or emergency contact.
Typical applications include steel mills, ports, mines, warehouses, power plants, tunnels, rail facilities, industrial yards, crane operations, utilities, and other harsh-environment communication points.

One Platform — Three Communication Options
Analog — LC103-DB-A
For standard PSTN or analog PABX systems. The telephone is powered directly from the analog line, with an operating range of 24–65 VDC, so no separate telephone power supply is required. Remote DTMF programming, programmable auto hang-up, delayed auto-dial, scheduled test calls, and one relay output are supported.
SIP / VoIP — LC103-DB-S
Supports SIP 2.0 / RFC3261, full-duplex communication, PoE IEEE 802.3af or 12 VDC power, browser-based configuration, web self-diagnostics, primary/backup SIP server switching, and two relay outputs. Supported codecs include G.711 A/U, G.722, G.723, and G.729.
4G LTE — LC103-DB-4G
Designed for locations where a fixed landline or Ethernet connection is unavailable or impractical. The 4G version operates from 12 VDC, supports remote SMS configuration and diagnostics, and uses an externally mounted SMA antenna with a 6.56 ft (2 m) cable. Regional LTE module configurations are available depending on project location.
Important 4G/LTE Compatibility Note
4G/LTE operation depends on more than signal coverage. The selected carrier SIM/account must be provisioned for the required service, such as voice, VoLTE, SMS, data, or SIP over LTE.
Device LTE band support, antenna location, signal strength, and carrier-side activation should be confirmed before installation. For some carriers, especially in the U.S., additional carrier approval or account provisioning may be required.
Customers may use their own compatible SIM card and cellular service plan; there is no mandatory LightCom cellular-service contract.
