LC103-FK-H-FB Open-Face weatherproof industrial telephone with horn and beacon
External Horn · Flashing Beacon · Full Keypad · Analog · SIP/VoIP · 4G LTE options | Heavy-Duty Outdoor | IP66 (NEMA 4X equivalent) | CE, FCC, RoHS, IK10, ISO 9001
The LC103-FK-H-FB weatherproof industrial telephone with horn and beacon is a rugged open-face communication station for factories, steel plants, mining sites, power facilities, tunnels, ports, rail infrastructure, utilities, and other high-noise industrial environments.
Its open-face design provides immediate access to the handset and keypad without opening a protective door. An external horn provides high-output audible call indication, while the remote flashing beacon adds a highly visible alert that can be positioned where personnel can see it across the work area.
Analog, SIP/VoIP, and 4G LTE versions allow the same industrial telephone platform to be used across different communication infrastructures.
Key Benefits

Full numeric keypad with programmable calling functions
Rugged industrial handset with noise-reducing microphone
Weather-resistant die-cast aluminum enclosure
Analog, SIP/VoIP, and 4G LTE configurations
Wall or pole installation
Suitable for demanding indoor and outdoor locations
Project-specific beacon, signaling, color, and labeling options
Audible & Visual Call Indication
In high-noise environments, an ordinary telephone ringer may not be enough.
The external horn provides stronger audible notification so personnel can notice an incoming call even when machinery, ventilation, traffic, or production equipment creates significant background noise.
The external flashing beacon provides a second, visual indication. Because it is separate from the telephone enclosure, it can be mounted higher or in a more visible position when required by the site layout.
For the comparable LightCom horn-and-beacon configuration, the signaling equipment uses an auxiliary power supply rather than relying only on the telephone circuit. Final power requirements should be confirmed for the selected LC103-FK-H-FB communication version.
Why Choose the Open-Face Version?
Choose the LC103-FK-H-FB when personnel need fast access to the telephone without opening a front door.
This is particularly useful at fixed operational communication points where:
calls are frequent;
operators wear gloves;
fast access to the keypad is important;
the telephone is installed in a protected or supervised industrial area;
a protective front door is not required by the application.
For locations requiring additional mechanical protection while the telephone is not in use, the enclosed LC101-KB-H-FB may be the more appropriate configuration.
Analog, SIP or 4G LTE
Analog
For sites with existing compatible analog PBX/PABX or two-wire telephone infrastructure.
Standard analog communication
Telephone-line operation on applicable configurations
Full keypad / DTMF dialing
Suitable for retrofit projects
Auxiliary power required for high-output external signaling where applicable
SIP / VoIP
For facilities using Ethernet and SIP/IP communication.
SIP-based communication
Integration with compatible SIP/IP-PBX systems
PoE or DC power depending on configuration
Web-based configuration on supported platform
Suitable for centralized industrial communication and paging applications
4G LTE
For locations where a landline or Ethernet connection is unavailable or impractical.
Cellular communication via compatible SIM
No local telephone line required
Useful for remote industrial locations
Carrier, LTE bands, VoLTE/service compatibility, signal strength, antenna placement, and power should be confirmed for each project
