The LC103-3DB-L 3-button weatherproof industrial telephone with flashing beacon is designed for fixed communication in harsh industrial, transportation, utility, port, mining, and public-safety environments.
Its open-face die-cast aluminum enclosure provides immediate handset access, while three vandal-resistant programmable direct-call buttons allow users to reach predefined destinations such as a control room, maintenance team, security desk, or emergency contact without dialing a full number.
The integrated flashing beacon provides a high-visibility visual indication for call or site-signaling applications. Beacon activation depends on the selected communication version and project configuration; the required trigger logic should be confirmed before ordering. On the Analog platform, the telephone line can power a top-mounted external light without a separate power supply. SIP models provide relay outputs for control of external devices.

The published dimensions apply to the base LC103-DB telephone body; overall height with the integrated beacon should be confirmed from the final LC103-3DB-L drawing before panel, wall, or enclosure planning.
Communication Options
Analog — LC103-3DB-L-A
PSTN / PABX, telephone-line powered, 24–65 VDC, 20–100 mA DC, DTMF/PD dialing, remote DTMF programming, programmable auto hang-up, scheduled test calling, and one relay output. Ringing level is 80 dB(A) at 3.28 ft (1 m). The Analog platform can also power a top-mounted light from the telephone line, so no separate telephone power supply is required.
SIP / VoIP — LC103-3DB-L-S
SIP 2.0 / RFC3261, full-duplex communication, PoE IEEE 802.3af or 12 VDC, browser-based configuration, web self-diagnostics, primary/backup SIP server support, and two relay outputs. Power consumption is approximately 1 W idle / 2.4 W operating, with ringing level 90–95 dB(A) at 3.28 ft (1 m).
4G LTE — LC103-3DB-L-4G
12 VDC operation, remote SMS configuration, auto-dial programming, remote diagnostics, and external SMA antenna with 6.56 ft (2 m) cable. Power consumption is approximately 0.3 W idle / 1.5 W operating, with ringing level 90 dB(A) at 3.28 ft (1 m).
Important 4G/LTE 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 must be confirmed before installation. For some carriers, especially in the U.S., additional carrier approval or account provisioning may be required.
Estimated Delivery Time
Analog / SIP: typically 3–4 weeks after order confirmation.
4G/LTE: typically 4–5 weeks, depending on cellular module availability, programming, testing, and final configuration.
