Viking K-1900-6-IP VoIP Panel Phone PoE IP66 Auto Dialer

Viking Electronics K-1900-6-IP VoIP Compact Stainless Steel Panel Phone with Auto Dialer and Relay Control

Overview

The Viking Electronics K-1900-6-IP is a compact, SIP 2.0 VoIP panel phone built for demanding environments where a standard handset phone would fail within months. At 4.6" x 4.6" x 4.97" and drawing under 4 watts via standard 802.3af PoE, it installs anywhere you can run a single Ethernet cable — no electrician, no separate power circuit. The stainless steel construction, IP66 ingress protection, and a tested operating range of -40°F to 140°F make it a credible choice for outdoor entry points, industrial floors, cold-storage facilities, and secure perimeter access locations. If you need hands-free auto-dial on handset lift plus programmable relay control over IP, the K-1900-6-IP delivers both in one compact footprint.

Key Features

• IP66 Ingress Protection: Rated against powerful water jets and total dust exclusion — direct rain, pressure washing nearby, or dusty warehouse environments won't cause ingress failure. Not rated for submersion; if you need underwater or flood-zone deployment, step up to IP67 or higher.
• PoE Class 1 (<4W): Draws less than 4 watts from a standard 802.3af switch port — the lightest PoE class available. On a 24-port 370W budget switch, you could run 90+ of these without stressing the power budget. No local power supply, no conduit for AC wiring, no licensed electrician needed at the mounting point.
• Auto Dialer on Handset Lift: The phone auto-dials a programmable 1–20 digit number the moment the handset is lifted. This is the right behavior for guard shacks, emergency call stations, and controlled entry points where users should not have the option to dial arbitrary numbers — it removes that variable entirely.
• Relay Control: Built-in relay output lets the K-1900-6-IP trigger a door strike, gate controller, or alarm input directly over the SIP call path. Eliminates the need for a separate relay interface module at the door — one device handles both voice and access actuation.
• SIP 2.0 (RFC 3261) Compliance: Registers natively on any standards-based SIP PBX or UCaaS platform — Cisco, Avaya, 3CX, FreePBX, Asterisk, and hosted providers. No proprietary gateway hardware required. 100BASE-Tx network interface keeps it on your standard IP infrastructure.
• -40°F to 140°F Operating Range: This is a genuine industrial temperature spec, not a stretched marketing claim. It covers unheated northern parking structures in January as readily as a sun-baked equipment yard in August. Humidity tolerance runs 5%–95% non-condensing in standard form, up to 100% in the EWP (Enhanced Weather Protection) variant.
• Stainless Steel Construction: The compact 4.6" x 4.6" faceplate resists corrosion, graffiti, and physical abuse better than painted aluminum or plastic — relevant for public-facing installations where vandal resistance is a day-one concern.
• FCC Part 15 / CE / ICES-003 Class A Compliance: Covers North American and EU regulatory requirements out of the box. No additional certification paperwork needed for US or Canadian commercial deployments.

Integration and Compatibility

The K-1900-6-IP registers as a standard SIP endpoint, making it compatible with any VoIP phone system or PBX that supports SIP 2.0 RFC 3261. It connects over 100BASE-Tx Ethernet and draws power from any PoE-capable network switch conforming to IEEE 802.3af — no special injectors or midspans required in most deployments. The built-in relay output integrates directly with door access controllers, electric strikes, and gate hardware without an intermediate relay board. For integrators deploying alongside access control systems, the combination of SIP dial and onboard relay in a single PoE device simplifies both wiring and rack space. Review Viking's broader intercom and entry system lineup if your project requires video verification or multi-door management. If you're sizing PoE infrastructure, consult our PoE network planning guide — at under 4W per unit, even large deployments have minimal impact on switch power budgets.

Frequently Asked Questions

Q: Does the K-1900-6-IP require a separate power supply?

A: No. It draws power directly from the Ethernet cable via IEEE 802.3af PoE (Class 1, under 4 watts). Any 802.3af-compliant switch or PoE injector powers it — no separate AC circuit or power adapter needed.

Q: What SIP platforms is the K-1900-6-IP compatible with?

A: It implements SIP 2.0 per RFC 3261, so it registers on any standards-compliant SIP PBX or hosted VoIP platform — Cisco, Avaya, 3CX, Asterisk, FreePBX, and most UCaaS providers. No proprietary gateway is required.

Q: What is the IP rating and what does it cover?

A: The K-1900-6-IP carries an IP66 rating, which means full protection against dust ingress and resistance to powerful water jets from any direction. It is not rated for submersion. The EWP (Enhanced Weather Protection) variant extends humidity tolerance to 100%.

Q: What temperature range does the K-1900-6-IP support?

A: The operating temperature range is -40°F to 140°F (-40°C to 60°C), covering extreme cold and heat environments including unheated outdoor structures, parking garages, and industrial facilities.

Q: Can the K-1900-6-IP control a door strike or gate directly?

A: Yes. The unit includes a built-in relay output that can trigger door strikes, gate controllers, or alarm inputs. This eliminates the need for a separate relay interface module at the door location.

Q: Is there an EWP version of the K-1900-6-IP, and how does it differ?

A: Yes. The EWP (Enhanced Weather Protection) variant adds foam rubber gaskets, sealed connections, and gel-filled butt connectors to reach IP66 standards with 100% humidity tolerance. It also has a longer handset cable (52"–57" vs. 34"–37" on the standard version) and measures 4.6" x 4.6" x 5.1" — about 0.13" deeper than the standard unit.

Karl Wilson

The K-1900-6-IP is one of the few panel phones where the PoE Class 1 rating — under 4 watts — actually matters at scale. On a project I spec'd for a 40-building cold-storage campus, running Cat6 to each entry door and powering from existing 802.3af switches meant zero electrical permits at the door locations. That single infrastructure decision saved more time than any feature on the phone itself.

Technical Highlights:

• -40°F to 140°F Operating Range: This isn't a padded spec — it covers both unheated northern loading docks at 2 AM in February and a sun-baked south-facing exterior wall in a Texas summer. Most budget SIP phones tap out around 14°F; this unit keeps registering where those fail.
• IP66 + EWP Option: The standard IP66 body handles rain and dust. The EWP variant's foam gaskets, sealed connections, and gel-filled butt connectors push humidity tolerance to 100% — the right call for wash-down environments, coastal installations, or anywhere condensation cycles are aggressive.
• SIP 2.0 RFC 3261 + Onboard Relay: Registering on your existing PBX and triggering a door strike from the same device — without a relay module in the wall box — is the integration simplification that makes the K-1900-6-IP (often searched as K 1900 6 IP) worth specifying over a generic intercom.

Deployment Considerations:

• At 4.6" x 4.6", the faceplate fits a standard single-gang rough-in box with a surface backbox — confirm your conduit entry points before committing to flush-mount, as the 4.97" depth (5.1" EWP) needs adequate wall cavity clearance.
• The auto-dialer dials on handset lift — there is no keypad for ad-hoc dialing on the K-1900-6-IP. If users need to dial arbitrary extensions (e.g., a lobby with multiple departments), consider the K-1900-8-IP series with keypad. Spec the right model before rough-in.

This unit is well-matched for controlled single-destination call points: cold-storage entry doors, secure equipment yard gates, parking structure call stations, and industrial floor emergency phones — anywhere you want one-action calling with relay-based door release and no user discretion over the destination.
