Viking Electronics LC-6 6-Line Concentrator for Emergency Phones
The Viking Electronics LC-6 is a six-port line concentrator that lets up to six emergency phones share a single analog phone line — the practical answer when code requires elevator or area-of-refuge phones at every floor but your building has only one POTS circuit to work with. The LC-6 (often searched as LC 6) ships as a compact 8.25" x 6.25" x 1.75" wall-mount chassis, accepts 120V AC or 13.8V AC input, and includes battery backup rated for more than four continuous hours — keeping life-safety circuits live through a power outage.
Overview
Multi-floor elevator and emergency phone installations routinely run into the same constraint: telephone company circuits are expensive, and provisioning six separate analog lines for six elevator cabs isn't realistic. The LC-6 solves this by concentrating all six Viking Electronics emergency phones onto a single line. It is designed specifically for use with the Viking 1600A Series elevator phones, and the emergency phone category it serves is tightly regulated — life-safety gear that has to work when it matters most. Battery backup exceeding four hours keeps the system live during utility failures without requiring a separate UPS.
Key Features
- Six Emergency Phone Ports: One analog trunk serves all six connected phones — eliminates the cost of provisioning multiple POTS lines in multi-floor elevator or area-of-refuge applications.
- 4+ Hour Battery Backup: Onboard battery sustains operation through extended outages, which is a code requirement in most jurisdictions for elevator emergency communication systems.
- Dual Power Input (120V AC / 13.8V AC): Accepts either standard wall power or a 13.8V DC-regulated supply, giving installers flexibility to integrate with existing panel power without an additional transformer.
- 25-Position Screw Terminal Block: All field wiring lands on a single 25-position terminal strip — no proprietary connectors, faster commissioning, and straightforward troubleshooting.
- 500 ft Max Run for LM-24D: The optional Viking LM-24D Line Status Display connects up to 500 feet from the LC-6, so the monitoring panel can sit at a building management desk rather than next to the concentrator.
- 2,000 ft Max Run for LV-1K Wiring: Viking LV-1K wire supports runs up to 2,000 feet — enough for most mid-rise elevator shafts without signal amplification.
- 32°F to 90°F Operating Range: Rated for standard conditioned mechanical room and elevator machine room environments; not intended for unheated outdoor enclosures.
- 5% to 95% Non-Condensing Humidity: Handles the humidity swings common in elevator machine rooms without requiring a sealed enclosure.
Integration and Compatibility
The LC-6 is purpose-built for the Viking 1600A Series elevator emergency phones. The companion LM-24D Line Status Display monitors all six ports and can be wall-mounted up to 500 feet away from the concentrator — useful when the machine room is not accessible to building staff. For wiring, Viking LV-1K cable supports the full 2,000-foot maximum run distance. If you are planning a multi-floor emergency phone system or specifying equipment for an area-of-refuge installation, pair the LC-6 with a compatible PoE switch infrastructure for any IP-based call routing beyond the analog concentrator stage. Review the emergency phone selection guide for code compliance considerations before finalizing line quantities.
Frequently Asked Questions
Q: How many emergency phones can the LC-6 support?
A: The LC-6 supports up to six emergency phones on a single analog phone line.
Q: What Viking phone models are compatible with the LC-6?
A: The LC-6 is designed for use with the Viking 1600A Series elevator emergency phones.
Q: How long does the battery backup last during a power outage?
A: Battery backup runtime exceeds four hours under normal operating conditions.
Q: What is the maximum wiring distance for the LM-24D Line Status Display?
A: The LM-24D can be installed up to 500 feet from the LC-6. For LV-1K wiring to the phone ports, the maximum run is 2,000 feet.
Q: What power sources does the LC-6 accept?
A: The LC-6 accepts 120V AC or 13.8V AC input power.
Q: What are the physical dimensions of the LC-6?
A: The unit measures 8.25 inches wide by 6.25 inches tall by 1.75 inches deep and ships at 3.2 lbs.
The Viking LC-6 comes up on almost every multi-floor elevator job where the building owner wants to avoid paying for five or six separate analog lines — the concentrator multiplexes all six phones onto one circuit, and the onboard battery backup rated at more than four hours covers the outage scenarios that matter most for life-safety compliance.
Technical Highlights:
- Single-Line Concentration: Six elevator or area-of-refuge phones share one POTS circuit — in a six-cab building, that can eliminate five monthly analog line charges entirely.
- 2,000 ft LV-1K Wire Run: Enough to reach the top of a 15–20 story elevator shaft from the machine room without a repeater or signal booster.
- 25-Position Screw Terminal Block: All six phone ports and power connections land on one accessible strip — no crimped connectors to fight in a tight machine room cabinet.
Deployment Considerations:
- The LC-6 is rated 32°F to 90°F — confirm your elevator machine room stays within that range year-round before mounting; unheated rooftop machine rooms in cold climates can drop below spec in winter.
- The LM-24D monitoring display maxes out at 500 feet from the concentrator, which is plenty for most buildings but worth laying out before you run conduit to a remote lobby panel.
The LC-6 is the right fit for new mid-rise construction and ADA area-of-refuge retrofits where code mandates two-way emergency communication at each floor and the telecom budget doesn't support individual analog circuits for every phone location.
