Viking E50-BK-EWP Video Entry Phone IP67 Flush Mount Black

Viking Electronics E50-BK-EWP Textured Black Video Entry Phone with EWP

The Viking Electronics E50-BK-EWP is a telephone-line-powered, hands-free video entry phone engineered for commercial and institutional door stations where you need two-way audio, a color composite video feed, and a faceplate tough enough to take abuse — all without running a separate power circuit to the door. The compact 2.84" x 1.8" x 1.65" phone module mounts flush in a standard single-gang box or sits proud on any surface with an optional VE-3x5 bracket, and the Enhanced Weather Protection (EWP) treatment lifts the enclosure to IP66, making it a legitimate outdoor candidate even in coastal, poolside, or chemically aggressive environments. If you've been searching for this unit as the E50 BK EWP, this is that product.

Overview

Entry phones at commercial doors solve a specific problem: give the person inside positive visual and audio identification of whoever is pressing the button, without requiring that person to open the door first. The E50-BK-EWP handles that job with a color video camera, a hands-free speakerphone circuit, and a blue LED that confirms the call is live — all driven entirely by the telephone line. No PoE injector, no 12V power supply, no separate cable pull. For retrofit installations into buildings that already have two-conductor telephone wiring at every door, that's a significant simplification.

The textured black 18-gauge 304 stainless steel faceplate measures 4.875" x 3.125" x 0.18" — slim enough to sit flush on a single-gang box without standing out, and stainless construction that resists dents, scratches, and the kind of casual vandalism common at apartment building entries and loading dock stations. The EWP designation adds foam rubber gaskets, sealed connections, and gel-filled butt connectors that together bring the enclosure to Viking Electronics IP66 standards — rated to handle direct water jets from any direction without ingress.

Key Features

• Telephone Line Powered: Operates entirely from loop current — minimum 18V DC talk battery and 20mA loop current. That means no separate power wiring at the door. In existing-building retrofits, if a phone line is there, you have everything you need to deploy this unit.
• Color Composite Video Camera: Delivers a visual of who is at the door before the door release is triggered. Particularly useful in door entry phone applications where intercom-only is not enough for compliance or liability reasons.
• IP67 Push Button Switch: The call button itself is independently rated IP67 — fully dust-tight and withstands temporary submersion. That's a higher rating than the enclosure, meaning the most-touched component is the most protected. Vandal attempts that try to force water in around the button won't find a path.
• IP66 EWP Enclosure: Enhanced Weather Protection elevates the full assembly to IP66 — protection against powerful water jets (not just rain). Designed to resist corrosion from salt air, exhaust, and chlorine, making it a usable choice for parking garages, coastal facilities, and pool access doors where standard IP54 or IP55 units degrade quickly.
• Operating Range -30°F to 150°F (-34°C to 65°C): That lower bound handles unheated vestibules in northern climates without a heater; the 150°F upper end covers direct-sun metal door installations in hot climates where surface temperatures spike well above ambient air. Most competitive units stop at -4°F or -22°F.
• 62dB Speaker @ 1m: Sufficient for a door station environment where ambient noise is typically 50–60dB. Not a high-noise industrial floor solution — if the door is next to loading dock equipment running, investigate a higher-output speaker option instead.
• Blue LED Call Indicator: Gives the caller confirmation the system is active. Reduces repeated button-presses from callers who assume nothing happened, which in turn reduces nuisance call volume to the inside station.
• CPC Auto Disconnect (300ms minimum): The Calling Party Control circuit detects a 300ms break in loop current from the inside station and automatically terminates the call — no need for the person at the door to hang up. This keeps the line clear for the next visitor without any action required on the door side.
• 25V AC RMS Ring Voltage: Compatible with standard telephone ringers and most PBX/KTS systems that output standard ring signals. Verify your PBX ring voltage output meets this 25V minimum before deploying.
• REN 0.8A: Ringer Equivalence Number of 0.8 means this unit counts as less than one full ringer load on the line — you can add this to an existing telephone circuit without exceeding the 5-REN limit most lines support.
• 18-Gauge 304 Stainless Steel Faceplate: Corrosion-resistant, non-magnetic stainless that holds up in humid and chemically active environments. The 0.18" profile keeps the installation low-profile against the wall surface.
• Flush or Surface Mount: Single-gang box flush mount is the primary install; the optional VE-3x5 surface mount adapter adds flexibility for concrete walls or locations where box cut-in is not practical. Plan the rough-in accordingly — conduit stub for single-gang flush gives the cleanest result.

Integration & Compatibility

The E50-BK-EWP connects directly to a standard two-wire telephone interface — analog PBX ports, dedicated door phone ports on KTS systems, or any analog line that supplies at minimum 18V DC talk battery and 20mA of loop current. The video output is composite color, routed separately to a video entry system monitor or compatible door phone controller. Verify your door phone controller accepts composite video input; IP-based video door systems will need a converter or a different platform. The CPC disconnect feature requires that the inside station supports CPC signaling — confirm this with your PBX vendor before spec'ing. For deployments requiring enhanced weather sealing beyond the base EWP, review Viking's DOD 859 supplemental EWP documentation. Pair this unit with a compatible door entry controller that supplies the correct line voltage and handles the video output for a complete system.

Frequently Asked Questions

Q: Does the E50-BK-EWP require a separate power supply at the door?

A: No. The E50-BK-EWP is telephone line powered — it draws everything it needs from the loop current of the connected phone line (minimum 18V DC talk battery, 20mA loop current). No separate power wiring or PoE is required at the door station.

Q: What is the IP rating of the E50-BK-EWP?

A: The push button switch is independently rated IP67 (fully dust-tight and submersion-resistant). The overall enclosure on the EWP model is rated IP66, meaning it withstands powerful water jets from any direction. The EWP treatment adds foam rubber gaskets, sealed connections, and gel-filled butt connectors for corrosion resistance against salt air, exhaust, and chlorine.

Q: Will the E50-BK-EWP work with my PBX or KTS phone system?

A: The unit connects to any standard two-wire analog telephone interface that provides a minimum of 25V AC RMS ring voltage and 18V DC talk battery at 20mA loop current. It supports CPC (Calling Party Control) auto-disconnect, which requires the inside station or PBX to generate a 300ms loop current break. Confirm CPC compatibility with your PBX vendor before deployment.

Q: How cold can the E50-BK-EWP operate?

A: The rated operating temperature is -30°F to 150°F (-34°C to 65°C). This covers unheated vestibules and outdoor installations in cold climates without a supplemental heater, as well as direct-sun door installations in hot environments.

Q: Can the E50-BK-EWP be surface mounted, or does it require a single-gang box?

A: Both options are supported. It flush-mounts in a standard single-gang electrical box (faceplate: 4.875" x 3.125" x 0.18"). For locations where cutting a box is not practical — concrete walls, for example — the optional VE-3x5 accessory bracket enables surface mounting.

Q: What is the video output type on the E50-BK-EWP?

A: The camera produces a color composite video signal. This routes to a compatible composite video monitor or door phone controller. IP-based video entry platforms will require a composite-to-IP converter or a different door station model.

Ted Perry

The E50-BK-EWP sits in a very specific spot in the door station market: analog-telephone-line powered with composite color video, EWP-sealed to IP66, and an independently IP67-rated push button — a combination that matters a lot in healthcare, multifamily, and institutional retrofits where the telephone infrastructure is already in place and you're not pulling new power or network cable to the door. I specify this unit specifically when the PBX or KTS system is staying put and the customer needs visual verification without a full IP intercom overhaul.

Technical Highlights:

• Line-Powered Operation (18V DC / 20mA minimum): Eliminates the need for a local power supply or PoE run to the door — a genuine installation cost reduction in retrofit scenarios where conduit capacity is already tight.
• IP67 Push Button + IP66 EWP Enclosure: The button is rated one full IP tier above the enclosure, which is where most vandalism and water intrusion attempts concentrate. The EWP corrosion treatment extends useful life in salt-air and chlorine environments well beyond what a standard IP65 faceplate provides.
• -30°F to 150°F Operating Range: That 180°F thermal envelope covers unheated Minnesota vestibule to sun-baked Arizona metal door without any heater or ventilation accessory — relevant when the installation is unmaintained and you need the unit to survive without intervention.

Deployment Considerations:

• The composite video output connects to a compatible door phone controller or composite monitor — verify your inside station or controller accepts composite input before ordering. IP-based platforms require a separate converter.
• CPC auto-disconnect (300ms loop break) requires the PBX or inside station to generate that signal. Not all analog ports on modern hybrid PBX systems do — check the port spec before finalizing the dial plan.

This unit is the right call for institutional and multifamily lobby door stations on existing analog telephone infrastructure — hospital service entries, apartment building intercoms, and school secure-entry vestibules — where adding IP infrastructure to the door is not in the project scope.
